Reading through some of the forums I decided to try the idea of using ‘export to DNG (Denoise & Optical Corrections Only)’ as a way to work on my DeepPRIME denoised images. Two things surprised me:
The export was very fast, much faster than a normal JPEG export with all of my corrections.
The output file was larger dimensionaly than the raw file. For example a raw file that is 2620x1956 exports as a 5185x3888 DNG. In this example the image was shot with a 20MP sensor, and that is approximately the size of the resulting DNG.
So for those that understand these things could you give me a quick explanation (or a link to point me in the right direction) as to what is happening here? I’m guessing (and that’s all it is) that the original raw file (ORF in this case) has some type of compression that the DNG does not.
I’m happy to share more details if I didn’t provide enough information. Thanks in advance for answering.
