This from an essay by Ben Breard, AfterImage gallery about dealing with untalented photographers.
"I try to handle untalented photographers gently and positively. Most any of them can improve with more years of work, but they still might not be at a gallery level. I try to be truthful, but it's not easy. Frequently I hear myself saying (chickening out), "We just don't have a market for your kind of work." I usually don't have the heart to pronounce, "Your work just isn't of gallery quality, and it may never be."
