I have run the gamut with clients. I have one client that is sooooo picky, Its very hard to shoot for them. Nice people, just very very picky.

I have had others that use my photos that I might have as a keepsake, but, not for ads.

Not to mention I see ads and think that they have made their dog look worse than it is with that photo. So, the long answer to your question is that NO many people cannot see a crappy photo
