Hi, I'm a new member seeking some voices of experience....
wow power leveling,
I've recently become interested in 3d after seeing some impressive photos on websites,wow power leveling
learning about Stereo Photo Maker (SPM), and finding that both parallel and cross-eyed viewing come
easily to me, thus dispensing with cumbersome viewing equipment. A couple of weeks ago I bought a used
Stereax beamsplitter and have fitted it to my Canon A590IS (incidentally, the Canon la-dc52g
supplementary lens adaptor for the Canon A-series makes a good beamsplitter mount). It performs quite
well despite the first-surface mirrors being in poor condition. It evidences the usual dark rectangle in
the centre at the widest zoom (35mm equiv.) and this can be minimised by moving to a longer focal
length, which also eliminates a surrounding image of the internal of the beamsplitter. The results, when
cropped, etc., by SPM, are reasonable but I decided to see if newer optics would improve things and have
bought a new SKF-1.
ffxi gil,
The SKF-1 was designed for a Zenit 58 mm slr lens but,ffxi gil when attached to the Canon, it produces a
much more intrusive central rectangle at all points in the zoom range (which includes an effective
58mm). I happen to have an old Minolta slr with a 58mm lens and, on that, the SKF-1 has a much-reduced
central rectangle - to the point of virtual disappearance at f/1.4, although becoming a problem above
approx. f/8. While the rectangle appears to be the result of the central blanked-off area at the front
of beamsplitters, this is merely sized to match the mirror geometry and sizes. I'm surprised then that,
at the same field-of -view, the results aren't very similar for the two lenses. Is it because the two
lens designs are very different? For example, maybe the fore-and-aft position of the effective lens
centre relative to the front element? Any comments from experts out there would be welcome.
cheap aion kinah,
I'm thinking that I may have to make a 4-mirror beamsplitter (along the lines described in this forum)
cheap aion kinah with optimised mirror sizes to get the best results. Any advice on what I should
particularly watch out for given the problem I have outlined?
wedding dresses,
The SKF-1 has sealed optics and,wedding dresses in this area, the Stereax suffers badly in comparison. I
have been thinking of using thin, "optically-polished", stainless steel mirrors as more robust than
first-surface mirrors. They are sold as mirrors, seem highly reflective, and look to me to be pretty
flat. Has anyone any knowledge of their suitability? Would SPM be able to take out minor aberrations
caused by lack of flatness,wedding dresses as it compensates for so many other deviations from the
ideal?
wedding dresses,
All help appreciated.
