Re: CR2 RAW file conversion
But what software are you viewing foto.cr2 with? It doesn't contain RGB pixels, so some software is converting it.

Re: CR2 RAW file conversion
What adjustments are needed to make the PS and IM results match? Were the camera settings at neutral? (PS will probably use them. IM won't.)

Re: CR2 RAW file conversion
Depending upon your IM version, you may need to use -set colorspace sRGB or -set colorspace RGB and vice-versa for -colorspace.convert E1DXINBI003200.CR2 -set colorspace RGB -resize 800x600 -colorspace sRGB out.png
What is your IM version and platform?
Describe how the colors are different?i tried, but the result is not good. image is dark and colors do not match with the original image.

Re: CR2 RAW file conversion
Photoshop could be assigning a different (Adobe) profile than sRGB when the file is opened. That might change the colors slightly.i'm using photoshop.

Re: CR2 RAW file conversion
Can you post your raw .CR2 file to some free hosting service such as dropbox.com and put the URL here so that the experts on raw formats can check and test with your image file?

Re: CR2 RAW file conversion
What made you choose that area to make average gray? A different result comes from using the white balance that was recorded by the camera:jose.sanpedro wrote:dcraw -v -6 -A 2000 2000 1000 1000 -T -O foto3.jpg foto.cr2
