I am the master of the 'work print' I have boxes and boxes of them. The exchanges are the majority of what prints I produce that get to be my 'finished' prints. Whether they are any good is beside the point, they definitely froce me to go the extra mile, as I know whoever's getting it is going to look very closely at print quality. I also generally select something I haven't printed before. Even postcards get better treatment than my regular 'work' prints. When you're flashing, split grade printing, 5 different burns & toning a postcard you know you're doing more than the minimum (ohh, that was my 1st postcard... I'm a better negative selector now!). I don't care what I receive, as long as the person has tried their best and taken a bit of care in the packaging to make sure it gets here as it left them.
