Since my Adobe Lightroom expired days ago (and right now it costs almost 200usd on Adobe's main page) I decided look an alternative and give it a chance. The main alternative I found is RawTherapee My main preoccupation about was about what happens when I import a Canon Raw 2 (.cr2) image and if it's work correctly. It works fine! I been trying like 20 minutes some changes and doing profiles until moment of saving a image THIS happens. I opened again an I found my changes on course, and I didn't lose anything, then I exported my result. What I found is something I been looking through the edit process that is a BIG NOISE on the image. Then I make another test on Adobe CameraRaw As you see, there is noise but in any way comparable with how RawTherapee manages it. Conclusion: Since I used the worst possible photo to edit, Adobe manages wide better the noise, doing it some preprocess that never gets same result on an app...
