I bought a package that is supposed to teach you how to correct your eyes and stop needing glasses. Im nearsighted. Anything to not wear glasses right?
Anyway, The focusing you do in to view this is one of the exercises in the package.

Is it helpful? Dunno.
Didnt work for me because it also required that you stop using your glasses.
I can not drive and otherwise function properly without mine.

I am not medically qualified so could not comment. Suffice to say if you can focus on a screen within 2-3 feet you should be able to freeview ...

hi,
great write-up... i've messed around with stereo photography before, however generally on things close-up. i've recently seen some fantastic landscape photography in stereo here on the Potn stereo thread, and i'm heading to Nepal next week so would like to give it a go there and see if i can capture the Himalayas in stereo.

Any suggestions or tips? i guess i'll be working in large steps rather than mm or cm movement. is there rules and guidelines for how much to move?

cheers

I would advise you to read around stereophotography sites and learn what you can. If you have specific points I'd be happy to talk about them in detail.

One general rule of thumb is your stereobase - side distance between shots - should be 1/30th distance between you and the nearest feature in the stereo. At the wide bases you may use, the result will be a lot of cropping, as only small area of each image will feature in each so take that into account when framing.

Anaglyph format will probably serve your needs better rather than pairs.

Get back to me should you need to consider specifics, otherwise I'd like to see your eventual stereos. :D

Has anyone used twin Canon 405Ds in a stereo setup? What was the lag between the cameras? I'm wondering whether an SLR Shepherd is necessary or will a wired remote to both cameras give accurate enough sync?

Twinned Dslrs have been effective with the Lanc Shepherd but the rig is big, cumbersome and of course expensive: the cost of doubling up in L glass would be prohibitive for many.

Times have overtaken the Lanc Shepherd with the introduction of Stereo Data Maker with synchronisation now measured in 1000ths of a second -- more than capable of freezing the motion of drops of water hitting a surface and fragmenting!

Thanks for responding! Yes, I read about SDM but it seems to only apply to certain p&s cameras. I will be shooting poster ads so I am hesitant to use something like even the G9, which seems to be the best camera compatible with SDM.

Here are the points which cause me to be reluctant but perhaps you can put my mind at rest?

1. Matching the focal lengths on 2 P&S cameras exactly doesn't sound easy.

2. I'm not sure if you can lock in manual focus on these cameras.

3. To sync with a flash unit I assume you would still need something like the Magic Flash? (see http://www.ledametrix.​com/magicflash/index.h​tml (external link))

4. So-so image quality, but that is a matter for me to decide. I hope that the anaglyph will help mask some of the IQ issues.

After some more reading on SDM it seems you can lock/control focus but I'm still finding no information about syncing an external flash.
