I prefer the lightroom images. I'd like to see 100% crops to judge this sort of thing.

What exactly does the "100% crop" term mean? The images I posted were right right off the camera with no additional cropping.

And to post the image on PotN you had to shrink it down to 800 pixels wide. That meant shrinking it down to 15% of the original linear dimensions. That means you can't see the original, individual pixels.

If you'd have cropped an 800 pixel wide chuck from the image you could have posted that without resizing - that's known as a 100% crop. It allows you to peek at the individual pixels. Some people believe that such pixel-peeking is vitally important, others couldn't give a monkey's what the individual pixels look like but prefer to examine the image as a whole.

7d support isn't final yet - it's only beta support, so there's more work to do yet.

I will be glad when they have something more official as the LR2.5 profile labeled "beta" is really off from what I'm seeing in camera / in DPP.

What I've done is to use a hex editor to replace the label inside the 50D profiles and they seem to do a better job than the "beta". I wasn't sure if 5D Mark II would be closer to 7D or 50D. I didn't see much difference so I went with 50D. Both seem to be better than the initial support.

Here's the steps if anyone wants to try it out:

1. Copy & appropriately rename the profile you want to clone from the original. On my machine the 50D profiles are in these two folders:

  • C:\ProgramData\Adobe\C​ameraRaw\CameraProfile​s\Adobe Standard\Canon EOS 50D Adobe Standard.dcp
  • C:\ProgramData\Adobe\C​ameraRaw\CameraProfile​s\Camera\Canon EOS 50D\Canon EOS 50D Camera *.dcp

Copy them to, respectively:
  • C:\ProgramData\Adobe\C​ameraRaw\CameraProfile​s\Adobe Standard\Canon EOS 7D Adobe Standard.dcp
  • C:\ProgramData\Adobe\C​ameraRaw\CameraProfile​s\Camera\Canon EOS 7D\Canon EOS 7D Camera *.dcp


2. Open the DCP in any hex editor (external link) (if you don't know what a hex editor is (external link), you probably shouldn't be doing this). For instance this file:
  • C:\ProgramData\Adobe\C​ameraRaw\CameraProfile​s\Camera\Canon EOS 7D\Canon EOS 7D Camera Faithful.dcp


3. Find the profile label at the top of the file (e.g. "Canon EOS 50D") and type over it with "Canon EOS 7D". In my case, the "50D" was 1 char longer so just replace the extra chars with "00" on the hex side of the screen. Make sure to name this exactly right as I believe it is this label that LR uses to match up with the camera model in the metadata.

IMG NOTICE: [NOT AN IMAGE URL, NOT RENDERED INLINE]

4. Save it.

5. Repeat for the Adobe Standard and each Camera profile.

6. Assuming you placed the files in the correct folder, named them correctly and updated each of camera labels, you should now have additional profiles for 7D images:

IMG NOTICE: [NOT AN IMAGE URL, NOT RENDERED INLINE]

I'd be interested in hearing if anyone has better success with 50D profiles, 5D Mark II profiles, or any others. In my experience, they still aren't quite right but a step better than the "beta" profile. Much less warm for sure.

Are they all full RAW, or did you use mRaw/sRaw? With bridge i'd say try clearing the cache, the same may be true of LR.

Nope, fingers crossed for the next release. I don't much like DPP so for the few mRaw I took I just batched them straight to jpeg, chose my keepers, then only processed the best ones. Even then I batched to TIFF then tweaked in ACR.

Thank you for the clarification.

...

Wow. That's one hell of an introductory post. I love it!

Another thing worth mentioning is that I had better results manually changing my white balance in Lightroom from 'as shot' to 'auto', even when the camera was set to 'auto'. Auto for the camera and auto for Lightroom are entirely different things.

Just saw this post... yeah, my images with my 7D in LR is much more warmer than OP's.

In DPP:

In LR:

BTW, love that I can shoot 3200 ISO and still have good noise control.

Well, it took me a week longer to get around to it but it was totally painless and the results look good. It'll do me until we get full support. If anybody wants to download the profiles (if you're not sure about playing around with a hex editor) then I could stick them somewhere.
