Not a problem

Lightroom Classic: Trouble with Canon 5d Mark III aspect ratio

Today I imported RAW images I shot on the Canon 5d3 with the camera set to Add Cropping Information set to 4:5 ratio. Crop lines are displayed on the camera LCD but you see the full frame outside of the crop when review files. Alarmingly, when I imported them to LR 4.1 RC, the images appeared cropped to 4:5. I though ok, I'll just go to the crop tool and I will see that a crop has been applied and I'll remove it. Unfortunately, there was no file beyond the crop lines, it could not be removed as far as I could tell. I called Canon and they told me to try Digital Photo Professional, a program that I never pay attention to. Sure enough, the images were intact when viewed there. There appears to be a bug when LR 4.1 RC encounters the crop tag on the raw file.

Correct, this is intended behavior.

Intended or not, the point of RAW images and Lightroom being non-destructive is that we have the OPTION of changing our minds later on.... I have to add my voice that this is not a good fixed option to impose on users.

I will repeat a posting in another thread here:

Eric, could you please describe the intended behaviour?

I have a camera with a 3:2 sensor. If I set the aspect ratio in the camera to 16:9, I still get a full 3:2 raw file (verifiable in RawTherapee) with metadata saying that the aspect ratio is 16:9.

When I import such a file into a raw converter, I expect one of two behaviours:

1. Ignore the 16:9 metadata and show a 3:2 image.

2. Use the 16:9 metadata to "pre-crop" the photo to 16:9, but still make the full image area availiable in the crop tool.

Instead Lightroom does this:

3. Crop the photo to 16:9. Throw all available image information outside the crop area away with no option for the user to use that information in the crop tool - even though the information is still there in the raw file and occupying space on the disk.

If #3 is really the intended behaviour, I think that a lot of us would like to hear Adobe describe the rationale behind this. It is very much against the tradition behind raw photography.

This is a general problem that also applies to other cameras as well, e.g. compact cameras like Canon G12, Olympus E-PL1, etc. - and probably future DSLRs that have the same feature.

With that in mind, I think it is a duplicate of http://feedback.photoshop.com/photosh...

P.S. The raws can be fixed using exiftool with option -m and the tags aspectratio, aspectframe, CroppedImageWidth and CroppedImageHeight (depeding on camera), but this may be risky depending on the raw format.

P.S. II: Proposal: Instead of "hard cropping" such raws, LR should apply a "soft crop" using its standard cropping tool on import. Using this method, the information in the metadata is not lost, but can be overridden anytime by the user. Furthermore, the crop tool can be modified that it contains "Original" (= crop as the camera settings) and "Full Frame" (= whole raw image area). A reset of the crop tool or the develop settings should revert it to "Original".

However, I see a problem here for photos already imported in LR3+4 using "hard cropping" because they have to be converted to "soft cropping", taking into account existing "soft cropping" and the coordinates of local corrections. Tricky, but should be manageable.

Absolutely agree to the P.S. II proposal above! I have the same issue with the Olympus OM-D E-M5 on cropped images. Please just apply a soft crop according to the camera settings by default instead of "hard cropping" the image!

I created a little LightRoom plugin, which automates the exiftool process and stacks the new raw on top of the old one:
http://tim.jagenberg.info/projects/de...

It's my first LR plugin, so it is quite possible that it still is somewhat buggy. So far I only tested it with Olympus ORF raws.

I updated the tool and now it should work on mac. I also successfully tested DNGs on windows:
http://tim.jagenberg.info/projects/de... -> DeAspect 0.1.2

The crop marks should be a hard crop with a jpeg image and go back to default (2:3 ratio) when processed in RAW. There needs to be a way to revert back to the original full frame image!

Why hasn't Adobe acknowledged this issue? It's so easy to test and verify. Granted, it may not bother that many people, but if there is a bug, at least acknowledge it. It seems like it would be pretty easy to fix.

It seems like this behaviour is intended, so there is (at present) no problem to acknowledge. See the post of Eric Chan at the end of the similar problem thread: http://feedback.photoshop.com/photosh...

How could this be intended behavior? It's destructive editing! Doesn't that go against the principle of Lightroom and working in RAW? Why make anything that can't be undone? The camera is sending all of the information and Canon's software, Digital Photo Professional, gives you the entire file. Obviously that is the intention of the camera manufacturers. It must be a simple issue of how LR choses to read a meta tag. I think Adobe should re-evaluate it's position on this and give the user the option. Otherwise the feature on the camera is not usable. I am a magazine photographer. I shoot a few covers and full page photos and I need to be able to shoot to layout. With 4x5 crop lines shown on my LCD, I am reasonably close to the correct format. But I can't use this feature if LR is throwing away information! Please reconsider!

Evan, did you read Eric's post in the linked thread? Here, I'll re-post it for you:

"Understood. In the future, we may be able to implement a mechanism for retrieving the full (uncropped) image data. I did not mean to suggest this was impossible, or that we hadn't considered it. We actually did consider it this time around, but it didn't make the cut for various reasons. "

Just read it. They obviously spent time developing this new behavior. I think it's totally unacceptable and needs to be addressed in the next release. It goes against the core values of RAW workflow. When you set White Balance in the camera, the WB setting can be changed in Lightroom. What is the difference? It's basic fundamentals.

Hey Eric,

as you are considering implementing a solution: I think it would be great, if that aspect-ratio meta data was mapped into a "Crop" development step applied after the initial import. This way, the photo would appear "as shot" after import, but the user would retain full flexibility to change his mind later on.

Greetings
Tim

"Didn't make the cut" implies they agree and want to implement this, but didn't have time given that there are always many more features to be implemented than there is time to implement them, so they prioritize and my guess is that this one was low on the list because it has a very simple workaround - don't set the camera to crop. I certainly agree that the new defringing controls are vastly more important and I would most certainly have chosen that feature over this feature every day of the week, had I been making the choices.

My point is that they could have saved even more time by not changing the way it used to work. I do not think you can conclude that implication from his comment. If that's what he meant, he should say so.

For me the crop marks in the camera are vastly important. It effects how I shoot. The shoot is irreversable. If you don't shoot a job they way it needs to be done, you can not always reverse it. In the past I have had custom focusing screens with crop marks but you can't change the screen in the new 5DIII.

It's better not to implement a feature than to implement it partially.

I don't use the de-fringing controls much. For the lenses I have, I don't find them very necessary

We all have our own priorities. If this is not a priority for you, why are you following this thread?

What was changed? I wasn't aware of a change here.

LR 3 ignored camera crop information and did not apply it to the RAW. LR 4 crops the raw. That is the change they implemented. You can read Timo's post here: http://gsfn.us/t/2v4fr

That is not exactly true. LR3 already used the camera crop information to crop raws, e.g. for Olympus XZ-1 or Canon G12. There was no general change - at least not from LR3 to LR4. However, it could be that there were changes for specific camera models.

That was my understanding as well, but I admit I'm not completely up on this so maybe, like you said, there was a change regarding some cameras or something.

I totally agree that the user *must* be able to access the raw data - it really does partially defeat the idea of shooting raw. Adobe - please make it so that the crop is applied, but that when you go into crop you get the full sensor data! This really seems to me the only logical thing to do. Honor the setting in camera but be able to access the sensor original information.

This is something they really should correct right away. In camera should be able to undone in LR 4.1. Right now I'm struggling with this problem and photos go to customer.. actually they're not because I have to make re-shoot. One days work for nothing.

Mike, you can use the Canon software Digital Photo Professional to remove the aspect ratio, but then you still have process the raw images with the Canon Software (DPP) program.

I wish there was a way could have the crop marks displayed on the back of the Mark III without impacting the actual image. As it is nice to be able to view the 4x5 ratio as a reference.

Well I just got screwed by this today. The CR2 have already been deleted after conversion to DNG, and now I discover that Lightroom has distructively edited the RAW files without any confirmation. Apparently I can't get the original image content back, and the client is waiting for her now-ruined photos. Brilliant.

Adobe, make fixing this a priority please!

Is there any intent on fixing this issue in a LR4 update? I sure hope so, otherwise I have about 75% of 1000 files from a couple of recent outings that will probably be worthless. Needless to say, I have turned the cropping info feature off, way too late. I would be satisfied if they could come up with a fix that totally ignored the crop info, actually I would be elated.

I did try removing the crop in Canon DPP and re-saving, didn't work. Even tried removing crop and doing a save-as, no fix. If you remove the crop and save as a tif file, the crop is removed, but the file quality was degraded.

Also PO'd at myself for not verifying the crop data feature before shooting a bunch of photos.

The worst part may be watching LR4 crop the image as it is being imported. That is rubbing salt in the wound.!

Your images are not lost. You can use exiftool to remove the crop from the image before you import.

Unfortunately, the command is a little different for different cameras, probably because the crop information is in a proprietary format. I don't know the correct command for a Canon. You will have to look in the exiftool output for a cropped and an uncropped image to find out what is different.

Perhaps you can find some inspiration in the commands for Sony and Olympus:

For Olympus, you can use this:
exiftool -AspectRatio=”" -AspectFrame=”0 0 0 0′′ -DefaultCropOrigin=”" -DefaultCropSize=”" -o target_filename.ORW source_filename.ORW

For Sony, you can use this to change a cropped height of 3376 pixels to 4000 pixels on a 24 MP sensor:
exiftool -sonyimageheight=4000 -exifimageheight=4000 -o target_filename.ARW source_filename.ARW
