I saw this critique on a website:
“…problem is, all these headshots look like they were taken at home, with a parents’ camera, in an attempt to commit without being fully committed. The only of these shots I’d use would be the second one (outdoors), but even that one is marginal at best. Professional photos take care of shadows, light balance, and color correction. These don’t.”
I see people using this kind of headshot all the time. I know money’s tight, and Canon or Nikon’s latest cameras are awesome, but headshots are pretty specific..
