I correct my files (for color, brightness/contrast, level etc) before uploading to Mpix and ordering prints. My question is, when checking out, do you let Mpix 'color correct' or ask them to turn this off? My concern is, I'm not sure what color profile Mpix uses, so some of my already corrected pics might come out dark or dull. Just wondering what you guyz do with your orders (i.e. wedding shoots). Thanks in advance!
