Re: Photographing a Person: A test of focal lengths

It seems to me that what most consider to be the transition range from a "distorted" head shot to a "normal-looking" head shot corresponds to focus distances that are in a range from about a half an arm's-length for the 17mm lens (~1.5 feet or "uncomfortably close standing distance") to just beyond an arm's length for the 45mm lens (>3.5 feet or "plenty of personal space").

Interesting, no?

Perhaps individuals that prefer portraits taken at 75mm are just less comfortable being physically close to other people.

Any psych students out there can feel free to use this for the basis of a dissertation. I don't require coauthorship. Just include me in the credits.

Edit: Dagnabbit! Looks like I got scooped.

Tom, that's a really cool article!

In another thread, I posted photographs of people taken at different focal lengths. I thought it would be useful to do a test with the same person at different focal lengths, so I enlisted the help of my neighbor.

The test wasn't as controlled as I would have liked: he changed is head angle slightly a few times, but I think an overall impression can be gotten.

(I'd like to get a manequin and do a similar test!)

Also, I moved his location when the sun became harsh on the face.

I positioned the tripod to frame approximately a head-shoulders pose, and moved back accordingly as I changed focal lengths from 12mm (a little less than 2 feet from lens to face) to 150mm (about 14 feet from lens to face).

Here they are -- focal lengths in m4/3 format, so double them to get full frame equivalent.
