An overview of using the Pentax Stereo adapter with a digital camera for creating 3D photographic portraits. Also a demonstration of how to process files in Adobe Camera Raw and StereoPhoto Maker software.
My father had one of the stereo adapters. He used it pretty frequently on his trips to Hawaii. He also did color prints and mounted them on card stock for viewing with an antique stereoptican.
I'd like to use my Pentax stereo adapter again. The last time I used it was in Bora Bora years ago. I think this time around, I'll duct tape the adapter in place so that it doesn't accidentally rotate. I'll also be doing something rather ambitious - taking 3D photographs underwater. It's a pity about the vignetting issue at f11. I would have preferred more depth of field.
Thanks Michael! Do you know whether this adapter could be made to work with cameraes that do not have full frame sensors, e.g. crop sensors, or the Fuji GFX 'medium' format?
For a cropped frame sensor, you would use a wider angle lens that had a 50mm equivalent. So for example a 35mm lens on a 1.5 or 1.6 APS sensor. I’m not sure if using a longer focal length lens (63mm) on the Fuji would work. Let me know if you try it. That would be interesting if you could use a GFX100s.
Great video, I need a solution to synch with flash and it seems to be one. Do you get some image quality compromise with that adapter, beside the resolution being divided by 2, and flare issues? I mean would you be able to use a 2D version as well? cheers
I’m using it with a 24 megapixel camera and am happy with the quality. There are cameras with even more resolution if you wanted to use just one side for a 2D print. If you need to sync with flash, this is one of the easiest solutions.
@@MichaelBrownArtist I'm going to use it on 40mp camera, so should be left with a around 2 X 18mp pictures after cropping. You mentioned the Lume Pad, do you own one? Can you use those in portrait orientation as well for 3d experience?
What you do with that picture where the flash reflection is in one half and not in the other? Can that be made into a stereogramm? I ask as I shot some pictures with this adapter but on mine (bought second hand) the outer edges of the mirrors are damaged. So in fact I have on the edges of the two half images (right on the one and left on the other) some patterns that are not the same.
@@MichaelBrownArtist they have some personal nostalgic value, maybe I will retouch. Cropping also would work, but I can not reproduce that (final) step where you crop the double pair after you matched it with the red-cyan superposing. Not having the instruction sheet I exposed with f:11 and f:16 (knowing that shallow DOF is either contraproductive in stereo photography). Now I have a very wide separator between the images of the pair. Still the frames are correctly matched by the automatic of the program and also adjusted. But after cropping (although I am not sure that happens at all, see above) I get the pair with that same separator, not only a black thin line.
