Hi all,
I am interested in making some 3D photographs, the concept seems cool.
What I noticed while looking closely to the pictures is that they are in fact two pictures, taken with 2 cameras a few centimeters away
in one we have the red channel, in the other the blue channel, our brain mixes them so we have a 3D photograph.
I am interesting in trying this.
Here's what I intend to do:
Make a tripod camera holder where I can slide the camera 5cm left or right, this should be quite easy to do.
take the same picture with the same settings on both sides of the holder.
in photoshop do the mixing of the 2 pictures, but how can I do it ??
ok from one blue channel, the other red channel, what do I do with the green ??
how to process ? I got the principle but not the direct way of doing it !!
anyone can help ?

I have never tried it but my approach would be to add a layer over the image in photoshop and colour it as close to the blue in your glasses. Then merge the layers using multiply. Do a similar process for the red channel with the original image. Then I would merge the blue and red layers using add. Let me know if I am waaaay off the mark ;-)
