Why Isn't My Canon 7D Sharp?
I just spent $2000 on the “best” APS camera and it's not sharp. Is it bad focus? Is it a bad sensor? What did Canon screw up? Not really.
- The current price of the Canon 7D is significantly less than $2000, in Canada. I was one of the first
sucker pioneer in Canada and paid the full price. I needed the camera then.

Finding Photos With Only Given Keywords
The problem with searching by keyword, is that Lightroom will show all the photos containing that keyword, whatever other keywords are present in that photo. What about the photos containing only that a specific keyword or keywords?

Flags — Lightroom and Photoshop
In Lightroom, I use P to “Pick” aka Flag a photo and U to “Unpick” aka UnFlag a photo. There are also the ratings and labels.
Lightroom is basically a photo editor, the curves are applied to the whole photo while Photoshop is a pixel editor. In Photoshop, I work at the pixel level, whether it's with layers or the other various tools, I modify the pixels.

Q: How To Apply Presets To Multiple Photos?
A: There's no direct way that I know of to apply a preset to many photos at the same time, up to the current version of Lightroom 2.5. But there's more than one way to skin a cat2 There are a couple of alternatives:
- Apply the preset during the import. It's just a regular edit and doesn't change the original photo, Lightroom just applies the preset to the preview.

Q: How to Delete Keywords From Photos in Lightroom?
A: It's not obvious, if you highlight the wrong keywords in the Keywording box and deleting them doesn't work. Why? Because Adobe decided not to provide it. The solution, instead, is to use the keyword list

How To Go A Few Steps Back Into The History
I am processing a whole bunch of files in Lightroom. Now I realize that I don't like the recent steps that I did and want to go back more than 1 step backward. Ctrl-Z / Command-Z only undo the last command, and if you did a select, that's the last one that will be undone. So are you stuck?
No, not really. Lightroom does not make any change to the original photo. This means that every time I look at a processed photo, Lightroom has to apply all the changes that I have done and in that order. So Lightroom keeps track of the history. Going to the “Develop” module, in the left pane, you can view the history of what has been done to that photo3.

Lightroom — Adding Keywords To Many Photos
There are two main ways of adding keywords to many photos in Lightroom:

Lightroom — Backing Up Your Catalog
I've always wished Lightroom would allow me to backup my catalog when I wanted. No, Lightroom does not allow me to backup catalogs. Lightroom decides for me when to backup my catalogs. And I often disagree with Lightroom.

Lightroom — Crop & Overlays
Some photographers are geniuses, some photographers are purists. However a photo comes out of the camera, it is and cannot be changed or altered. The photos are always full-frame... Painting is the "art of adding to a blank canvas". Photography is the "art of removing from real-life onto a photo". I don't have that luck of being such a photographic genius. I'm no Cartier-Bresson, I strive, but I'm not there yet. I crop most of my photos.
Everybody knows that Lightroom includes cropping tools. By Typing R, in any module, Lightroom will take you to the crop tool in the Develop module. Then you can crop left, right, top and/or bottom.

Cropping to Fixed Size In Lightroom
I'm in process of making moo cards. For the one that don't know, moo cards are business cards where you can set as many as 50 photos per batch of 50 business cards. The requirements are that the photos must be 1039 pixels by 697 pixels at 300 dpi. These dimensions include the bleeding areas.

Q: Where's my EXIF data?
A: Lightroom is so versatile, it has everything. Lightroom does the digital asset management with the keywords…, the processing of the photos with the develop module, the printing, the web… I'm sure that somewhere in that huge beast, there's a small hidden module to make coffee. Very few people have the 2 monitor setup. I'm not one of them. I have what used to be a huge 22" monitor, now it's getting small. Since there's so little screen space, Lightroom hides a lot of things. One of them is the EXIF data. You can see it from Library module.

Lightroom: Another 20% in Performance
Last month I order a new computer from Dell, a powerhouse, a monster, it took 3 weeks to arrive. It's an Intel iCore7, a 4 CPUs with hyperthreading behaving like an 8 CPUs computer with 8Gb of RAM and a terabyte hard drive. I bought the Dell because it was so cheap, almost $600 less than the equivalent computer at the “cheap” and high volume computer place.
It seems that Dell, HPs and the other computer manufacturers make more money loading the computer with all these 30 days preview softwares. I hate that, so I reformatted the hard drive and did a clean install. Lightroom performance is very much dependent on the speed of the computer. Today's tips are for Windows only! It applies to both Vista and Vista 1.1 Windows 7. But they will again improve the Lightroom performance since the computer will not be busy managing the display.

Lightroom — How to Set File Names
Most people, including Adobe's default, use the date as the directory for the name of the photo, so the names look like: 2008 then 05 then 01 then the filename. So when did you travel to New York? Do you remember the year and the month? I don't, because I don't think that way.
I like my filenames to be NewYork-20080501-0345.dng. This means that I took the photo in New York, on 1-May-2008, and that was the 345th photo of that series.

Lightroom — How to Set Panels Behavior
The Lightroom panels are driving me nuts! They come, they go. Whenever they come and go, it changes where things are. If I move the mouse too quickly, the panel does show up again, I have to click on the panel actuator, the triangle. So I prefer to switch to manual.
To control the appearance and disappearance of the panel, you will need to right click on the panel actuator, the grey triangle.

I set my keywords in Lightroom, I also make sure that I save them, but Bridge does not see my keywords
That's because Lightroom, by default, only save all information and changes in it's own database. Lightroom doesn't save it to the photo if it's a DNG file or to the XMP sidecar if it's in another format. You need to tell Lightroom to save all the changes to it's database and to the XMP sidecar or the DNG file with:

Lost My Picks
Q: I picked over 200 photos, copied them to my main collection and now when I filter for the picked photo, I get nothing. Zippo. What happened? Where did my picks go? What should I do?
A: Yes, that's right! Somebody at Adobe in San Jose decided that flags, both “Pick” and “Rejected” are local to the current collection. This means that when you copy or move a photo from one collection to another collection, the flag is not copied along.

Lightroom — Lousy Photo Rescue
The photo is lousy! A few photos can be rescued, most of them can't. How do you quickly judge if you should spend the time to rescue it? But you can quickly try by switching to Black & White. Press the “v” in the Library module or the Develop module just to see if the photo will work. Black and white photos have a different feel. Then you can later improve the conversion with the Gray Scale Mix.
It's quick, just the letter “v”, lowercase. You don't like the photo in black and white? Either Ctrl-Z / Command-Z to undo and not having the action in the history or “v” again to return the photo to its original colour.

Lightroom: Negative Queries
What's a negative query? A negative query is when I want to know what it's not. For example, I want to see in Lightroom all the photos that are not about Walter, a dog. When we look in the selection it says “starts with”, “ends with” or “contains”, but most of the times it does not say: “Does NOT contain”. It would be nice but Lightroom does not allow it.
But wait! Lightroom does allow for the negative queries in the Library Filter, but it doesn't say it in the selection menu. Lightroom has the “!”, without the quotes, operator which means NOT.

Lightroom — New RAW Formats And DNG
You have just bought a new Nikon D3x or a new Olympus E30 or a new Canikon Z45, and either you don't want to upgrade your Lightroom or your Photoshop or can't upgrade your Photoshop or your Lightroom because of some plug-in will not work with the new version or some killer bug that will affect you.
Adobe tells you that you will have to upgrade or no new camera support. In fact, Adobe provides free support for all the same cameras as the latest Lightroom or the latest ARC5. Since the beginning, Lightroom has supported the DNG6 format and at all the versions of Photoshop CSx support the DNG format.

As you work on your images in Lightroom, all of the changes are being saved automatically into the Lightroom/SQlite database.

How to select a catalog when starting Lightroom
It's always a pain when Lightroom opens, it opens the last opened catalog. That's OK if you just have 1 catalog, but when you have, like me, more than 1 catalog, it's a problem. So either open Lightroom with the last opened catalog, wait for the opening and then switch or:

Lightroom — Slow As Molasses Or Lightning Fast?
Adobe claims that Lightroom is extremely fast. Tons of people on the Internet complain that Lightroom is slow as molasses. Who's right? Both. You can make Lightroom either run slow or fast depending on how you operate it. The major problem is that most people don't bother to understand how Lightroom works, they only learn press this key or that key... They must be the same people that take photos instead of making them.
Let's first understand what Lightroom does, and then you can operate to make Lightroom fast. Lightroom is a database program to catalog photo, to track them, to rate them and retrieve them. It has some editing facilities that are very similar to the raw processing in Adobe Photoshop.

Speed tip — Raw Cache
Lightroom and Photoshop use the same ACR, Adobe Camera Raw module to process the photo into the Develop module. The difference between Lightroom and Photoshop is that the ACR is built-in Lightroom, while in Photoshop, it's a stand alone application.
When Lightroom reads the a photo for the first time, Lightroom adds that photo to the Camera Raw Cache. The problem is that there is only so much cache. By default it's only 1 Gig in size, it's not that many photos, so the older photos are removed from the cache to make space for the newer photos.

Lightroom — Speedup Your Computer
In today's blindingly fast computers with the burning hot CPU and astronomical amount of RAM, the slowest part of your computer is the hard drive. Modern hard drives are fast but they are from 50 times to 500 times slower than your RAM.
Lightroom is extremely disk intensive. Although most of its catalog is loaded in RAM, the photos, the cache, and the previews are not loaded in RAM but are read from your hard drive.

Why is the histogram not the same on Lightroom and on Photoshop?
When looking at the histogram9 in Lightroom vs the the same photo in Photoshop, the histogram look very different. There are lot more clipping in the Photoshop histogram than in the Lightroom histogram?
This is due to the fact that there are different colour spaces in Lightroom and in Photoshop. Most likely the colour space used in Photoshop is sRGB and Lightroom is either Adobe RGB or ProPhoto RGB.

Lightroom — Workflow & Smart Collections — Part 1
A large part of my Lightroom workflow is implemented via the magic of Lightroom's Smart Collections. Smart Collections are dynamic filters, where you assign a few rules, and Lightroom will update the filter according to your selection criteria. So it will match the photos as they are changed or as they are updated.
Collections are static listing of photos. You will need to add the photo manually by dragging and dropping the photo in the "regular/plain" collection.

Zoom Levels
In the Library Module, you can zoom with the Navigator. The standard zoom levels are FIT, FILL, 1:1 and the variations of 1:…
Too many people check their photos at 1:1 or 100% zoom level, to examine all the pixels. I used to do it too. The problem with 100% zoom level is that in “real life” it's never used. I'm not the only one to harp on the pixel-peepers. Adobe also recommend using the 1:1 or 100% zoom level only in the Develop module and when using the brushes.

Lightroom Misconceptions
Lightroom looks like a very simple product but it's very advanced and can be very complicated. It's so good that I almost don't use Photoshop anymore. But there are many misconceptions. Here are some the biggest misconceptions:
- Lightroom will not match your cameras rendering when working with raw files. The camera shows only the jpeg preview, not the raw data. Lightroom applies its processing to the raw data. You can emulate the camera preview with presets or create your own camera profile.
Lightroom Misconceptions: read more →
Q: How to to create a Lightroom preset that adds +0.5 to whatever the current exposure instead of an absolute value?

All processing done by Lightroom in the Develop module is always done with the 1:1 previews, except for the cropping operations.

You have read my article Lightroom: Slow As Molasses Or Lightning Fast? where I mention that Lightroom has to build it's previews on the fly if they don't already exist. This will make Lightroom and your computer very, very sloow. But you didn't generate the 1:1 previews during the import.

Lightroom — Real Life Workflow
Everybody talks "Workflow". What's a workflow? It just a sequence of operations12. So here is my sequence. It's the best! For me! Why because it works for me! I have processed as many as 5000 photos in a month in Lightroom.
I hear you say: wait a second, there are people that claim that with their workflow, they can process 3000 photos in an evening. Actually, it's like comparing "hamburger flipping" and cooking "a full gourmet meal". They only import and while only assigning a couple of keywords and only delete the "bad" photos. My other limitation is that I can do this photo editing for only so many hours in the evening. Today, you will get the overview, then in the many following installments, you will get the actual details, including the why of such and such step.

What size you you make your photos for web display in Lightroom?
Lightroom allows you to set the size of a photo in pixels when exporting the photo. Everybody has their own “recommendations”. Some says to make it 500 pixels wide, some say 250 pixels wide... How big do you want your photo to be at 72 dpi13? So if you want a photo to be 4 inch14 wide then make the photo to be 4x72 = 288 pixels wide.
Wrong! What's wrong with these “recommendations”? The assumption that the standard screen resolution is 72 dpi. Most of these people are Mac users. The standard Mac resolution for the screen is 72 dpi, but the standard Windows resolution is 96 dpi! Many Windows users have set their computer to use the large fonts which convert their desktop to 120 dpi. A few extremely “poor sighted” people will have a resolution of up to 196 dpi. The use of 72 dpi makes it easy to convert the fonts from pixels to points, because they're the same.

Lightroom: Workflow & Smart Collections — Part 2
A large part of my Lightroom workflow is implemented via the magic of Lightroom's Smart Collections. You can see part 1 at: Lightroom: Workflow & Smart Collections — Part 1.
Smart Collections are dynamic filters, where you assign a few rules, and Lightroom will update the filter according to your selection criteria. So it will match the photos as they are changed or as they are updated.

The Keepers
Today, all cameras have a motor drive that can take at least 3 photos per second, some as many as 10 frames per second. 32Gb memory cards are becoming common place, that's 1200 photos per card for a full frame camera.
What are the keepers? Those are the photos that awe the customer. The keepers are the photos you want to keep 10 years down the road. The basic question is: “How do to find the keepers?”
Lightroom: Very Slow Speed
Yesterday, I got a phone call from Alice, a friend, complaining about how slow her Lightroom has become. She uses Mac and I'm a Windows guy. She wanted me to come, I wasn't too keen, she uses Mac and I'm no Mac expert. I can identify the screen, the mouse and the keyboard but what about the right clicks on a Mac? Nothing that important yesterday so I went.
I arrived and Alice showed me how slow her Lightroom was. It was slow, very, very painful. Actually, it wasn't just Lightroom, the mouse was very sluggish and I noticed that every time she was doing something on the screen, lights on her router15 were flashing. Why were they flashing? Was something wrong with her network? Now that's something that I understand. So I started asking questions, like:

Many people complain that the stacks don't work. It's usually because they didn't read Lightroom's RTFM16 or maybe it's because there is no manual supplied and no much of a help file. Here are some of rules for stacking photos in Lightroom 2.x.
- You cannot create a stack using images in a Collection or Quick Collection. You need to be in a folder for creating stacks.

Flags — Lightroom and Photoshop
In Lightroom, I use P to “Pick” aka Flag a photo and U to “Unpick” aka UnFlag a photo. There are also the ratings and labels.
Lightroom is basically a photo editor, the curves are applied to the whole photo while Photoshop is a pixel editor. In Photoshop, I work at the pixel level, whether it's with layers or the other various tools, I modify the pixels.

How To Go A Few Steps Back Into The History
I am processing a whole bunch of files in Lightroom. Now I realize that I don't like the recent steps that I did and want to go back more than 1 step backward. Ctrl-Z / Command-Z only undo the last command, and if you did a select, that's the last one that will be undone. So are you stuck?
No, not really. Lightroom does not make any change to the original photo. This means that every time I look at a processed photo, Lightroom has to apply all the changes that I have done and in that order. So Lightroom keeps track of the history. Going to the “Develop” module, in the left pane, you can view the history of what has been done to that photo3.

Some photographers are geniuses, some photographers are purists. However a photo comes out of the camera, it is and cannot be changed or altered. The photos are always full-frame...

I'm no Cartier-Bresson, I strive, but I'm not there yet. I crop most of my photos.
Everybody knows that Lightroom includes cropping tools. By Typing R, in any module, Lightroom will take you to the crop tool in the Develop module. Then you can crop left, right, top and/or bottom.

Very few people have the 2 monitor setup. I'm not one of them. I have what used to be a huge 22" monitor, now it's getting small.

Lightroom: Another 20% in Performance
Last month I order a new computer from Dell, a powerhouse, a monster, it took 3 weeks to arrive. It's an Intel iCore7, a 4 CPUs with hyperthreading behaving like an 8 CPUs computer with 8Gb of RAM and a terabyte hard drive. I bought the Dell because it was so cheap, almost $600 less than the equivalent computer at the “cheap” and high volume computer place.
It seems that Dell, HPs and the other computer manufacturers make more money loading the computer with all these 30 days preview softwares. I hate that, so I reformatted the hard drive and did a clean install. Lightroom performance is very much dependent on the speed of the computer. Today's tips are for Windows only! It applies to both Vista and Vista 1.1 Windows 7. But they will again improve the Lightroom performance since the computer will not be busy managing the display.

I like my filenames to be NewYork-20080501-0345.dng. This means that I took the photo in New York, on 1-May-2008, and that was the 345th photo of that series.

The photo is lousy! A few photos can be rescued, most of them can't. How do you quickly judge if you should spend the time to rescue it? But you can quickly try by switching to Black & White.

Then you can later improve the conversion with the Gray Scale Mix.
It's quick, just the letter “v”, lowercase. You don't like the photo in black and white? Either Ctrl-Z / Command-Z to undo and not having the action in the history or “v” again to return the photo to its original colour.

They must be the same people that take photos instead of making them.
Let's first understand what Lightroom does, and then you can operate to make Lightroom fast. Lightroom is a database program to catalog photo, to track them, to rate them and retrieve them. It has some editing facilities that are very similar to the raw processing in Adobe Photoshop.

Speed tip — Raw Cache
Lightroom and Photoshop use the same ACR, Adobe Camera Raw module to process the photo into the Develop module. The difference between Lightroom and Photoshop is that the ACR is built-in Lightroom, while in Photoshop, it's a stand alone application.
When Lightroom reads the a photo for the first time, Lightroom adds that photo to the Camera Raw Cache. The problem is that there is only so much cache. By default it's only 1 Gig in size, it's not that many photos, so the older photos are removed from the cache to make space for the newer photos.

Why is the histogram not the same on Lightroom and on Photoshop?
When looking at the histogram9 in Lightroom vs the the same photo in Photoshop, the histogram look very different. There are lot more clipping in the Photoshop histogram than in the Lightroom histogram?

Lightroom Misconceptions
Lightroom looks like a very simple product but it's very advanced and can be very complicated. It's so good that I almost don't use Photoshop anymore. But there are many misconceptions. Here are some the biggest misconceptions:
- Lightroom will not match your cameras rendering when working with raw files. The camera shows only the jpeg preview, not the raw data. Lightroom applies its processing to the raw data. You can emulate the camera preview with presets or create your own camera profile.

Q: How to to create a Lightroom preset that adds +0.5 to whatever the current exposure instead of an absolute value?

Lightroom: Finally a good camera profile, now what?
After using your new Canikon D6xMk3, finally somebody comes out with a great camera standard. The photos, with this new camera profile, are outstanding. National Geographic, here we come, too bad Life folded a few years ago. The only problem is how to apply it to all the photos and not one at the time.

Lightroom: Horizontal vs. Vertical
When people want to buy photos from you, especially from stock, they have certain requirements. One of the more often used requirement is the photo to be horizontal or vertical 10. If you are like me, I don't record it every time, instead of that I let Lightroom almost do it for me. I say almost because it's not fully automated, just very simple and quick to do.
I have 2 smart collections:

Lightroom: How to Delete All Keywords at Once
I am reorganizing my keywords in the WIP11 catalog. I need to delete 1394 keywords. I explained in Deleting Keywords how to delete one keyword at a time, but over a thousand keywords? Very, very, very painful! Too painful.
Lightroom does not provide the facility to delete all the keywords, but you can...

Lightroom — How To Generate The 1:1 Previews After Importing
All processing done by Lightroom in the Develop module is always done with the 1:1 previews, except for the cropping operations. You have the choice of when Lightroom will generate the 1:1 previews, either before you will need them or when you will need the 1:1 previews. You have read my article Lightroom: Slow As Molasses Or Lightning Fast? where I mention that Lightroom has to build it's previews on the fly if they don't already exist. This will make Lightroom and your computer very, very sloow. But you didn't generate the 1:1 previews during the import.

How to have multiple photographers in the same Lightroom catalog, and identify the photos for each photographer?
In the import, create a metadata template for each photographer. The metadata template has the Creator's Name as the photographer's name, see #1.

Lightroom: Photos Without Location
Some people do their metadata in bulk. I don't, I don't have the patience. A big portion of my metadata is done during the import, but not everything can be entered during the import of the photos.
The 5Ws: What, When, Where, How and Why. I often need to answer these questions. One of them is the Where. I have a smart filter that allows me to identify what I have not entered. I work at it, in small doses. My smart filter catches the Country, the State/Province, the City and the Location. The important part is the Match any.

Lightroom — Real Life Workflow
Everybody talks "Workflow". What's a workflow? It just a sequence of operations12. So here is my sequence. It's the best! For me! Why because it works for me! I have processed as many as 5000 photos in a month in Lightroom.
I hear you say: wait a second, there are people that claim that with their workflow, they can process 3000 photos in an evening. Actually, it's like comparing "hamburger flipping" and cooking "a full gourmet meal". They only import and while only assigning a couple of keywords and only delete the "bad" photos. My other limitation is that I can do this photo editing for only so many hours in the evening. Today, you will get the overview, then in the many following installments, you will get the actual details, including the why of such and such step.

Smart Collection Within Smart Collection
I want to create a smart collection within an existing smart collection.
No, you cannot create smart collections within smart collections. A smart collection is an active “filter”, that is updated every time it does get a “focus”.

What size you you make your photos for web display in Lightroom?
Lightroom allows you to set the size of a photo in pixels when exporting the photo. Everybody has their own “recommendations”. Some says to make it 500 pixels wide, some say 250 pixels wide... How big do you want your photo to be at 72 dpi13? So if you want a photo to be 4 inch14 wide then make the photo to be 4x72 = 288 pixels wide.
Wrong! What's wrong with these “recommendations”? The assumption that the standard screen resolution is 72 dpi. Most of these people are Mac users. The standard Mac resolution for the screen is 72 dpi, but the standard Windows resolution is 96 dpi! Many Windows users have set their computer to use the large fonts which convert their desktop to 120 dpi. A few extremely “poor sighted” people will have a resolution of up to 196 dpi. The use of 72 dpi makes it easy to convert the fonts from pixels to points, because they're the same.

Lightroom: Workflow & Smart Collections — Part 2
A large part of my Lightroom workflow is implemented via the magic of Lightroom's Smart Collections. You can see part 1 at: Lightroom: Workflow & Smart Collections — Part 1.
Smart Collections are dynamic filters, where you assign a few rules, and Lightroom will update the filter according to your selection criteria. So it will match the photos as they are changed or as they are updated.

Lightroom: Megapixels vs. Print Size
You just bought the latest Canikon at 18 megapixels or at 24 megapixels. How big of a print can you do? Almost unlimited. How can that be unlimited? Won't your photos become just dots? Actually that depends on a few of things:

People And Keywording
In my keywording tags, I have the category: People. It's divided in people that I know and people that I don't. So far it makes sense. Either you know the person or you don't.
I do a lot of photos about dogs and street scenes. A vast amount of these photos do not have anybody in them, but I still have them tagged under the category people.

The Keepers
Today, all cameras have a motor drive that can take at least 3 photos per second, some as many as 10 frames per second. 32Gb memory cards are becoming common place, that's 1200 photos per card for a full frame camera.
What are the keepers? Those are the photos that awe the customer. The keepers are the photos you want to keep 10 years down the road. The basic question is: “How do to find the keepers?”
Lightroom: Very Slow Speed
Yesterday, I got a phone call from Alice, a friend, complaining about how slow her Lightroom has become. She uses Mac and I'm a Windows guy. She wanted me to come, I wasn't too keen, she uses Mac and I'm no Mac expert. I can identify the screen, the mouse and the keyboard but what about the right clicks on a Mac? Nothing that important yesterday so I went.
I arrived and Alice showed me how slow her Lightroom was. It was slow, very, very painful. Actually, it wasn't just Lightroom, the mouse was very sluggish and I noticed that every time she was doing something on the screen, lights on her router15 were flashing. Why were they flashing? Was something wrong with her network? Now that's something that I understand. So I started asking questions, like:

Working With Stacks in Lightroom 2
Many people complain that the stacks don't work. It's usually because they didn't read Lightroom's RTFM16 or maybe it's because there is no manual supplied and no much of a help file. Here are some of rules for stacking photos in Lightroom 2.x.
- You cannot create a stack using images in a Collection or Quick Collection. You need to be in a folder for creating stacks.
