DSims: You probably meant it as a negative, but I kind of like that you find the logo is distracting. My rationale is this: I've seen logo that are huge and take 10-15% of the frame, which isn't the case here, but my watermarked shots are used for web sharing (facebook, blog, e-mail) and after two years of doing it, people started to recognize the logo and immediately associate my name with it. It has definitely gotten me some commissions.
Is it distracting to the point of taking away from the subject, though? That is the question. I used to place it in a corner, but I find it does its job better when placed in negative space , as if it were an ad. None of my clients ever complained about it (I do provide a DVD with unmarked photos for very low resolution prints (4x6" or wallet size), whereas anything bigger than 4x6" must go through me.)
I don't charge a lot compared to boxed studios in my area (350$ for a one hour session, with two 8x10 and five 5x7 plus wallet sheet, whereas my competitors charge 500$ for less) but I should mention I am a 25 years old full time university student and only shoot professionally full time during the summer. It's definitely the high season right now. A great time to re-orient my business' niche.
I do thank you for your feedback, I will try reducing the logo's opacity to 50% and see if it has the same impact, or simply using the initials in the box for a more subtle look!
