Lens for nude shoot

[William Whitaker]

Gosh, photography sure has gotten expensive!

wrt your original question (I think...) If using a 210mm (or 8-inch) non-telephoto lens, think of the focal length as an f/stop, i.e., f/8. As your lens-to-subject distance decreases (camera gets closer to the subject) you will have to move the lens away from the film plane in order to hold focus. When you're close enough to the subject that the lens is 11 inches from the film plane, your bellows factor is 1 stop (f/11 - f/8 = 1 stop). That's the conventional rule of thumb, anyway. And it is completely independent of the state of dress of the model. I admit it's simplistic, but it dispenses with non-linearities and is easy to remember.

Every time I try to do nude photography, I either catch a cold or get sunburned.

I worked for a commercial photographer that always kept a yard stick handy and figured out his bellows factors that way (we did a lot of product shots fairly close up) I always wondered why this method had not been taught in the Photography School I went to

I keep a tape measure with the camera, and use a table I made for each lens. The method Will mentioned is great too.

Ndwgolf, I made an online simulator that might be useful for you https://apenasimagens.com/en/focal-l...s-and-framing/

I just divide my bellows extension by my aperture and get my f/stop.
