Re: [photo-3d] P&S

[Linda Nygren <lnygren@xxxxxxx>]

Many autofocus P&Ss don't even *have* an infinity focus lock. The first
time I tried this aerial technique I had a camera that would not fire at
all because the plane window was "too close". (It was a pentax zoom)
Then I got a new P&S (a different model Pentax) that had the infinity
lock feature but the brand new camera malfunctioned and all I got was
some weird error messages. Since I replaced that defective camera, I
have had bad luck in that the plane windows have been in such bad shape
that I haven't even bothered to try. One of these trips I will get a
chance to try again, although I typically only fly about once a year.

I *have* gotten some nice aerial shots of clouds with a Realist on
occasion, where they were close enough that the depth was pretty good
even without the wing-in-the-foreground effect. One trip I was making a
connection in Pittsburgh and had a nice photo op looking down the
smokestack at some power plant with nice clouds in the view, but I was
of course at the end of a roll of film, which then proceeded to detach
itself from the spool in the camera at the end of the roll. (The only
time that has ever happened to me). Although I had no resistance on
trying to rewind it, I made the mistake of opening the camera back and
ruined the film that I had already exposed. If I hadn't been in a hurry
to reload, I would have thought it through and left it for a darkroom.
Oh, well. -Linda
