Nude photography is an art form in itself and you need to understand that before you attempt it. My suggestion is to get some idea of what type you wish to shoot. Almost every photographer has some nerves about shooting nudes in the beginning. I did, I never thought anyone would pose nude for me if I wanted to shoot some. We are not talking about your girlfriend lying on the bed using a cell phone camera. That is just not even something to discuss in the fine art arena.
Now once you get the idea you need to find the model. There are going to be many of you asked to take what is now considered boudoir photography. This could be your neighbor, friends, friends of friends and others. I did many that way including in-law photos one time.
My first suggestion is to find out what type of images they want, not you. You may not be willing to take those shots or you may want to only take those types of shots. Talk to the client and make sure you are on the same page. Of course, if it is something you are doing for yourself and paying the model, shoot away.
I do not like color nude photos because if they are not touched up a lot most of the time they show the imperfections we all have in the skin. Black and white changes things dramatically. It also lets the eye concentrate on the image instead of the imperfections.
Lighting is a key. A great shot is from the back standing with various degrees of the feet being spread some. I like the head turned to the side and the lights from the side to help focus on the curves of the body.
While the 50mm is a good portrait lens it does not do well for nudes as most professional models and others prefer some private space. I suggest at least an 85mm lens like the ones Nikon has. You can also use something like the 70-200 for good shots.
Now for the model, keep the room warm. Not hot unless you want sweat in the shots, but you can get that effect using a spray bottle. Cool rooms keep the skin tighter in case that needs to be an option. Now some shots like the nipples to be extended. Warm rooms have a tendency not to do that. That can also be changed with cool items, cold items by the model themselves. They know what works on them.
I prefer to shoot nudes without showing the face for many reasons. If I am doing a package for someone I used to shoot a full shot in a semi nude state or in lingerie as the cover shot. That way if the images get out there is nothing to prove it is anyone person. Of course tattoos have changed that some and may need to be covered by something if privacy is an issue.
The item that will get you in trouble the most if not properly done is the poses. Keep them simple unless you are using professional model. If you are, they can help you as they know how they look the best and will also have no issues with you getting closer for more intimate shots. If you have no idea and the client has no idea get some magazines and books on fine art photography and you will see many options. Just make sure that the poses are comfortable for the model. You need to have them in a comfort zone for the shots to work.
Do not forget the releases for legal purposes as they show you did this a part of an assignment or project and if they look young, get a photo id.
Good luck. KISS, keep it simple stupid.
