In the realm of modeling photographers there are what we call GWC's, which stands for "Guys with Cameras". These are guys who go to Walmart or Best Buy, get an entry level DSLR with the kit lens, take a couple hundred images of their friends and then pass themselves off as "modeling photographers". As you might expect, their images are little more than snapshots. Subjects perfectly centered in the frame, no depth of field control, no use of fill flash when it is needed, etc. In other words, they suck.
To my horror, I read a profile of one of these GWC's who stated for a 2 hour shoot, that he would shoot 200 frames and guarantee 10 good shots. In a 2 hour shoot I may shoot 50 and 40 are good. I immediately emailed him and told him he needs to remove that from his profile. For you to broadcast that you have a 4-5% success rate that you are telling the entire planet that you totally suck as a photographer. I offered to take him on as an unpaid assistant to mentor him on some of the finer points of modeling photography and his response was indignant. I thought fine, if you want to be a lousy photographer your whole life have at it. I am certainly not going to waste my time with you. I have told aspiring models that although everyone has to start somewhere, as I did a long time ago, they have to keep in mind that their modeling portfolio is their resume. You would not walk into a job interview with a resume hand written on a cocktail napkin. Why then would you have crappy images from a GWC in your portfolio?
