hi
i have 2 tattoos. one on my back small tribal effect and one on my ankle which is getting added too tomorrow.
the only time i have had a problem with the tattoo in modelling is on commerical jobs. it sometimes goes against me. but most of the time the photographers i work with have been ok with the tattoo. they just photoshop them out if not appealing to them in the shot.
what i do say is u will never please everyone all of the time. and if it is what u want to get do it for yourself and ur own reasons. but think carefuly before getting it done as it is permanent and u will have to look at it everyday. it will be expensive to get done but even more expensive and painful to remove should u decide against it.
good luck
