3-D flower shots

Lord Vetinari

Some cross-eye stereogram flower shots. The last one was a PP accident but I liked the colour (should be yellow/white)

Ahhhh another beautiful series of images I cannot make work for me
Ohhhhh well one of these days I will figure out how to be cross-eyed

Thanks Stu and Skippy
You're going to have to learn to view these skippy
In the meantime two of the above shots.

These were the two that I liked the most by far. The 3-D effect was fantastic. Skippy, you have to really cross your eyes so that you see 3 distinct images from the two. Sorry you can't see these two.

Thanks for the kind comments all - glad you enjoyed them.

Very nice Brian.

These shots are focused stacks are they also? There seems to be a great deal of DOF in the individual images. How do you caprture stereos? Do you move the cemra right/left a fixed amount - say 65mm or so? That is a typical interpupillary distance.

Skippy,

You will need to wear you bifocals to see these. Do you have normal stereopsis? Normal depth perception? Is your vision normal in both eyes?

If so, look at the computer screen and hold your finger up in front of your nose about 6-8 inches out. Look at your finger - this will converge your two eyes, now, gradually begin to look at the computer screen, and it should pop into three dimensional glory. It may take a few tries, but it looks lovely when it happens.

Thanks for the comments Pathfinder. The first and last shot are focus stacked, so you end up doing quite a few shots for a stereo.
Yes these 3-Ds are taken with what is called the cha-cha method- take 1 shot move sideways and take another shot. I then use a freeware prog stereophotomaker to put the shots together and align them properly both for horizontal alignment and also for the stereo depth.
The amount of movement is not fixed at the eye space distance, it's linked to the nearest subject distance, so you are supposed to move approx 1/30th of the nearest subject distance (from the focal plane) so for macro shots that may be as little as 5mm but for flower shots it's around 10cms. I'm afraid I don't measure it I just do it but sometimes take a series of pan shots around the subject and find which pair works best.
It's a bit of a hassle doing them but if you can freeview these I think the final result is worth it.

damn my lack of depth perception!

They are sweet when you separate the two images, copy them into their own layers on top of each other, and then turn the top layer on and off repeatedly. I did an animation in imageready, but since it's not my image I won't post it.

No problems with you posting the result- Sounds like a 3-D wobblogram as I call them.

The depth on the two that are focused stacked are absolutly amazing. I've never heard of this technique though, can you point me somewhere where I can find out more information on this.

Myself, I've played around with HDR a lot, and I notice there isn't any on this site. (a search for HDR turns up zero hits) What is the general feelings towards them on this forum. I know some sites don't like them at all. I try to keep my HDR's more realistic, not so saturated looking.

Why not start a new thread with some examples of your HDR work? I'm sure you'll get a good idea of dgrin's general feelings about them if you do that.

See http://www.flickr.com/groups/macroviewers/discuss/163367/ for a short tutorial on focus stacking.
I'm sure I've seen some HDR threads here.

Thanks Brian, I've DL'd the program and will be playing till the wee hours tonight. Read a lot of your tutorials also, great stuff.
