I wouldn’t blame such a simple editor for not being a raw developer, but pretending to be one is cheating. After opening a very common CR2 file, the program is actually showing – and editing – only the embedded (highly compressed) jpeg preview image. Which is worse than nothing. I have noticed this also with one of the previous versions of this program. Such “approaches” were the reason I made a couple of raw files with fake preview jpegs. Although the difference is easy visible without that. End of testing.
