I was just spending some time getting to grips with DxO. I exported some images to file as Jpegs, they were in the order of 20Mb. I thought I could get away with half size for what I wanted as I have no intention of discarding the raw file!
I see a scale in DxO export settings, Quality 0-100, must be percent right? That is the first assumption that will prove a point!
It obviously isn't percentage, but what is it, from trial and error I find that somewhere in the 96-97 range gives half size files! Please see attached list.Dxo jpeg sizes

The blue highlighted set is from one image, I realised it was a crop when I went to compare the raw file so I repeated the 95-100 set and added the raw for comparison. Can anyone tell me how this scale works, it just seems completely random that a quality of 50/100ths (%?
) can give a file size of 1/16th the full size file.
Someone must know the answer to this, please! It's making my brain ache! (How do you draw a smiley with smoke coming out the ears?)
Thanks in advance for help with this, I know it is not necessary to know the answer but enquiring minds need (like) to know.
