You can work for me as a freelance DI artist. However, I will have to know how fluent are you with Photoshop, and how detailed and accurate you are. Your skill level shall determine your wages.
I will usually give you two sample images to work on. I will not tell you what I want. This way, I know how good you can spot problems. You have 15 minutes to show me the results.
It is a game of speed and accuracy. If you cannot complete your assigned task within that time frame, I am sorry but you are out.
