I'm planning ahead. I'll be back on the road soon and not have much time to spend at BPN, so I was looking ahead at the weekly themes.
I'm wondering what fits the 3D theme. I used to do some 3D composites that require some skill to see, but I don't think that's what you mean here?
Attached is a quick example I shot this morning of what I'm talking about.
In order to "see" the three dimensions, you have to almost cross your eyes and at some point the two images will merge into one and look very three dimensional. You can slightly move your head and it will appear that you can see around the foreground objects (sunflower in this case).
Patti, Thanks for providing the link and for giving us some info. I was thinking for the theme that we would concentrate on making images look 3D by using any and all techniques. Including but not limited to shading, composites, lighting etc. Contestants should create only one image per post and the effect would have to be visible on the posted image. Hope that defines it a bit more-if not let me now.:) I think the right sunflower image shows 3D look using the FG and Bg effectively.
Those 3D images drive me crazy. I have yet to be able to see one successfully. Actually your comment about crossing your eyes is the most useful trick yet. Almost seeing this in 3D... Was it shot with a special camera? ..TFS
Thanks Denise. I didn't think this type of image was what you had in mind.
Nick,
There are special cams that will do this, but you don't need them. These are shot using regular cameras. I just used a 20D with a 16 to 35. I was very close to the sunflower head and I took a shot with the center of the camera slightly to the left side, then I moved about 3 inches or so to the right keeping the camera parallel to the fence as before and took another shot.
Then I processed both shots and put the left one on the right and the right one on the left which is what you have to do for the "eye crossing" procedure.
The farther away you are from the point of interest (focus), the longer the distance between shots. I did one of these from an airplane shooting the clouds relative to the ground. I waited a few seconds which in commercial airplane speed is quite a distance. It really did look 3D.
If shooting some trees in the midground with a backdrop of mountains, you can move several feet.
But the important thing is that you keep the camera parallel to the background for both shots.
I've seen lots of images using this technique, Patti, and find them quite interesting. I've never really tried taking them myself though. I find that in order for me to see them correctly the images have to be in parallel view which means you put the left one on the left and the right one on the right.
Ah, yes, I hadn't thought of that. The distance is important in viewing. I should have made it smaller so that the normal viewing distance that most people sit from their computers would make it easier to see. I do have to sit back to see them.
Question for Later
