Raw editor for T7/1500 images

[davetelling]

I have a new Rebel T7, and I'm having a hard time finding a shareware/freeware raw file editor. I have tried Raw Therapee and UFRaw, but both just show my raw files as mainly bright pink backgrounds. I read that for UFRaw, the program doesn't recognize my camera - and looking at the camers list, the T7 is not listed. So, any ideas as to what might work? I see many recommend shooting in raw format because it has the most picture information, but it's a problem if the editor can't work with it. I had hoped ot use UFRaw to convert to tiff so GIMP could import it, but that's not working. I'm open to suggestions!

It's been a while since I got my T6i but I knew the SW DL was mentioned somewhere at the start...make that manual your best friend. I went as far as to have mine printed, spiral-bound so it lays flat. 6"X8" format, not too small, not too big.

John,

The manual I have is printed, in 3 langauges, and very tiny print!

I download the pdf and install on my phone and tablet.

Dave, Yes, I know the printed manuals from Canon are tiny when they actually include them and I have 20-20 vision....I also have the PDFs on my phone and tablet but prefer the printed one at times. I do like the search feature of PDF files to find things, it's like an index on steroids.

I understand Costco is good at restocking returned items as new!

Do You have some facts to substantiate that claim? I'd really like to know if they really do that.

Several months ago I bought my Canon SL2 "Kit" from Costco. It appeared to be a factory sealed box with all the docs and warranties. The lenses included are probably not up to your standards, but the camera works GREAT for me! Any problems I've had are all related to my inexperience.

RawTherapee 5.8 works and so does darktable. UFRaw hasn't been updated for years.

I did try Raw Therapee, and it did the same as all the other "free" apps - pink everywhere. I am going to try the Canon DPP and see how that works.

Pink means that the black level isn't correct. For example older RawTherapee or older darktable versions that  haven't got the raw support for a camera model yet. T7 got raw support last year.

I have attached print screens from RawTherapee, darktable and one pink one from darktable with the black level put to zero. In the pink one you will also see the optical black area that raw converters normally don't show you.

Optical black areas can be used to remove the random banding issue from EOS R.

Hello Peter,

I feel really dumb right now. I went back to my download folder to see which version of raw Therapee I had gotten, and it was 2.41 (!). Not sue how that happened, but I did download 5.8, and all is now much better. One thing I did notice, is that the same file opened in RT has a lot of what I assume to be noise specles (multi-colored pixels scattered all over the image) that I do not see in DPP4. I turned off de-noising, sharp mask, etc. and the difference is still there. I also saw the same "noise" (or whatever it is) opening the file in PhotoscapeX.

Raw Therapee image - note the multi-colored speckling.         DPP4 image - no specling, but looks like things are not as sharp, although I don't have sharpening turned on in RT. If I DO sharpen in DPP$, no speckes appear.

So, at this point, I'm leaning toward DPP4.

"Do You have some facts to substantiate that claim? I'd really like to know if they really do that."

I do not personally because I don't utilize Costco or Sam's Club.  I read a reply here on the forum from an individual that was a victim of it. I thought, oh well, he's just a complainer and not very responsible because of other posts he has made.  However, I have since paid attention to some of my friends locally here that thought they had bought some items from Costco that were obviously opened. My apologies to the first guy reporting for doubting.

MPO, I would never, ever, buy a camera from Costco or Sam's Club or Walmat either for that mater. If you can buy some sausage and a rug and tires at a store you probably aren't choosing the best place to buy a camera, IMHO, of course. Also goes for Amazon!

"...at this point, I'm leaning toward DPP4."

And at this point you are making the right choice.  DPP4 is going to have the most accurate conversion of a Canon Raw file.  Canon is the only source that knows exactly how to accurately convert their Raw files.  Everybody else guesses how.  The freebies and open source software are at the low end of that guess work.

Adobe is on top for non-Canon software. Basically because it is the most widely accepted and used photo editing software available. Bar none. Period!  So, if you aren't going to use Photoshop/Lightroom, use Canon's own DPP4. Personally I prefer PS (ACR) conversion over DPP4 and the fact I almost always wind up in PS, I simply prefer to start there.

As you can see, the image with noise is brighter and sharper. Those things increase the visible noise. Probably you use the default settings in RawTherapee that increases the contrast. I find darktable easier to handle.

I use all three raw converters. darktable, RawTherapee and DPP4. DPP4 doesn't have support for Linux so I need to use a VirtualBox. I really like the lens correction, but the lens correction in DPP4 is only for Canon lenses. RawTherapee and darktable use Lensfun as lens correction database. It means you can add any lens.

If I shoot raw and want to have the exported jpg to look like jpg straight out of the camera, but with higher image quality, DPP4 is easiest to use.

With both RawTherapee and darktable it is possible to remove the maze pattern from EOS R. It was not possible with DPP4 or Lightroom in December 2019. Perhaps Adobe and Canon have solved the problem in March 2020?

Different raw converters, different strengths and weaknesses.

I have noticed the same thing.  There is no malicious intent.  It is just simply sloppy inventory control, IMHO.
