Comps and Zed Cards. Make your presentations to an Agent impressive. Include Comp or Zed cards. Both sides are used. Name, Unions, specs.
Comp cards are usually in black and white.
It is sometimes hard to find someone to do this technique, however, here in the Los Angeles area, some 'Sir Speedee' printers do it. Format is generally about 6 X 9 inches. You should have lots of left over shots from your photo shoots. Keep these in a small portfolio or album, to bring along to any interested parties. This is not a paid commercial, but in Los Angeles area, I would like to make a recommendation for Head-Shots and Comp work.
