I remember reading some years about a way to practice visualization and judging appropriate focal length.
Unfortunately, I haven't been able to find it anywhere on the internet, and am sure someone here knows about it.
Basically, it involved using an empty slide mount, and a thread or string attached to the mount. The string was marked or knotted, but I don't remember exactly how (every 5 or 10cm?). You could hold the lide mount up and look through it, and when you get the composition you want, by looking at the thread you can see what focal length would give the same perspective.
Does anyone else know about this? Anyone use it, or recommend it? Cheers, Thor --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx- Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org
