Why do you recommend RAW images?
When using RAW images we are able to extract a lot more information from the file resulting in much more detailed, accurate, and desirable corrections. In addition, our famous PRIME denoising only works on RAW images.
Why do I need to use unedited images?
To apply automatic corrections for your specific camera body / lens pair, we need to be able to identify the equipment and shooting conditions with 100% certainty.
To be able to correctly identify the camera body / lens pair, our software needs access to original, unedited exif information (this info tends to get edited / lost when images are processed). To apply the corrections and achieve desirable results, the image needs to be unaltered prior to being processed through DxO PhotoLab 3.
What will happen if I try a processed image?
The camera body / lens pair with which you shot the image may not be correctly identified by DxO PhotoLab 3 (if at all) resulting in no automatic optical corrections.
Can I use JPEG? TIFF?
You can use jpeg and tiff images, though you will get much higher quality corrections if you start with RAW!
