The 50mm lens is what people usually consider a normal prime lens because it has a normal perspective similar to the human eye. Do not try to shoot too close to your subjects as the barrel distortion would be more obvious, unless that is the intention. I shot this picture with a very barebones setting, just window light, white bedsheet as reflector and my trusty old Nikon 50mm F1.4 AFD. Just add exposure compensation to blow out the highlights and you get a somewhat high key effect! Cheers!
