Well, a few things to keep in mind when photographing your beefcake images: using a slightly shorter lens, like a 35mm, 40mm,45mm or 50mm lens length, can exaggerate the size of a man's arms and chest when used at typical full-body to half-body distances. You can MAKE a man's arms appear larger and more-powerful, and make him appear substantially taller, by NOT using the 70-105mm lens lengths, and by dropping the camera height a little bit lower than normal. This also works on the female form as well.
I had occasion to photograph a rather average to shorter than average height, very good-looking man in his mid-20's this August, as well as his lovely pregnant girlfriend for a maternity/couples shoot. Indoors, the Nikon 45mm f/2.8 AI-P lens was the go-to lens for exaggerating her belly size, and also for making him look taller,and more-muscular in his arms.
The key is to not get too close...stay about 7 to 12 feet away from the subject, and pay HUGE attention to what the lens is actually doing as the camera is raised, or lowered, and moved even a foot or two farther or close toward or away from the subject.
We hear these ideas that XXmm or XXXmm is the best lens to use. In indoor, boudoir or living room distances, there is plenty of use for moderate-wide to semi-wide angle lenses--as long as you do not get too physically close to the subject. But in that 7- to 12-foot range, the lens length used can really be used to a huge degree to make the body's various parts look bigger, or more prominent, and stature and or leg/length really significantly altered from reality, or altered from what you would get by shooting from farther back with a telephoto lens. This is really critical, and you will not hear much about this from YouTube-era shooters or people who do not fundamentally understand perspective and apparent perspective distortion as properly defined.
Sue Bryce, well-known ladies' glamour shooter? Her favorite lens? Canon 35mm f/1.4 L prime, for close-in work to accentuate the body's shapes and size of various parts: hips, waist, leg length, chest areas, etc.
If the camera is placed closer than about 7 feet, then the nose and chin start to become oddly larger than is typically optimal. The closer the camera, the more you can work with apparent perspective distortion, to make things closer look larger. On reclining poses,. the legs will look longer if they are projected toward the camera. If the chest is leaned forward, in front of the belt-buckle area, the chest region will look bigger. Lowering the camera even 3 to 5 inches can add a HUGE amount of apparent height when working with a shorter lens in the 7-12 foot distance range, with ANY camera format.
