The talented Jessica Walsh just posted a super helpful entry on how to photograph your work.
A basic understanding of photography skills is important for graphic designers. I can’t tell you how many times I’ve seen a well done piece of design be ruined in portfolio settings by poor archival photography. Your design work will often live on largely by the photographs you take of it. These photographs are what potential employers will look at online before deciding to call you in for an interview. They will be what gets posted to design blogs and ffffound, and they will forever haunt you in your narcissistic moments when google image search your name. So it’s important to be happy with the photos of your work.
