So I'm trying to buy the right software that will help me to convert a huge file into the size prints I want. How do you guys do this? Say for instance I'm using a 21.1 mp camera. We know the file is going to be HUGE. How do most of you go about getting your prints. Save it to an SD card..? And take it to a photo shop? Do you have to resize first? If so how do you do it and using what program.
