yup, 3 is camera jpg
1 is DPP+PS and 2 is ACR+PS.

workflow for 2 is really quick and its the reason why i'm thinking about leaving DPP completely out of the whole process.
i know people reported before that theres color issues with ACR due to using adobe color profile instead of camera profiles, but latest version of ACR reads camera profiles (Neutral, Standard, Portrait, Landscape) and it seems to me its applying them correctly.

i'm guessing if you have a photo which is good as it is and only need a little bit of sharpening and correcting distortion/CA/vignetting and maybe adjusting white balance, DPP is the way to go, but as long as you feel like photo needs editing in PS (especial lightening or darkening parts of the photo), using ACR is better then using DPP.

what are your thoughts on this?
