Here are thirteen examples of using Photoshop to improve a CD cover. For cataloging purposes, every recording I own has it's cover scanned, making this a job that never ends! Most of my CDs come from thrift stores, so they are often in need of some work.
Sometimes it makes sense to combine two or more discs into one recording, requiring either a modified or brand-new cover. For this Rachmaninov, I made a new one.
