whilst on my holiday around europe I got into the habbit of shooting in+ S2 Jpgeg, I was doing this as family back home wanted to see lots of photos not just my 30 or 40 favourites which I would go the effort of PP, and in order to save space I would just delete the versions of the photos that I didn't deem worthy of spending time on PPing.
Having come back I didn't change it back since my computer was reformatted and the codec I was using to view files on my computer is gone, and for some bizarre reason I can't get it working again so hence I'm still shooting in + S2 so I can preview the files and the open up the ones in ACR
however going through my photos from this mornings sunrise I noticed that the images actually look different to the ones I open and do no adjustments to what so ever
let me explain with an example
the image on the right is the file completely un edited, and the one on left is the file opened up in ACR then straight away saved as a .
could anyone shed some as to why this is occurring?
