I have Lightroom 5 and would like to send out some photos for printing to Walgreens. My question is: What is the best way to have the photo I see on my screen to look some what accurate for printing ? Such as colors, saturation etc. I don't have calibrating software, etc. was thinking of trying Windows 7 calibration. Basically just want to print something for my dad and sister that looks decent and can be hung on the wall. Preferably 8x10. I'm afraid any larger would not look good. I shoot in raw. Any suggestions and advice would be appreciated. Thanks all.
