Just a question - what exactly are you disappointed with? This isn't a dig at you for not being happy, it's a genuine query. Mine last year (my first marathon) were rotten, and this year's are much better: more of me and pretty well-framed. The actual prints are okay without being great and could have been framed better, but my only real complaint (apart from the fact there was no finish-line shot of me) was the cost: four 5x7 shots for £53, with no reduction for more than one, is far too much.
So what is it everyone is unhappy with? Quality, cost, how you look in each shot, number of shots of you?
