I absolutely agree Skip that we should look to push borders, go for the different angle and so forth. But in that sense you can then argue for the putting together of absolutely any objects, however inappropriate, and simply get out of it by saying 'I was going for something different!' In Brit lingo we call it 'a cop out!'
If this was a real guitarist in the nude I wouldn't have a problem with it as such, it is more the fact that she so clearly is not a guitarist nor has the faintest clue how to hold one or whatever that prevents the image from gelling in a way I would want it to.
I have heard of that nude cellist you refered to as well actually. I guess there is nothing new in her rationale comment: after all, every naturist I have ever heard on TV or magazine articles or whatever has used the sime worn-out comment 'It is the most natural thing in the world. It just feels totally natural!' Well, each to their own I guess, not for me to tell them what they should or should not do, but for me, I might not dress up for dinner but I do always stay dressed
So keeping it photographic, my point is really about whether this partiular lady and the guitar work together in this picture but sadly my feeling is they don't. Now if she wants a couple of guitar lessons, i'll be happy to help on two conditions.... she puts some clothes on and she gets them nails cut
Cheers,
