As I cross my eyes with difficulty I image you guys leaning into your screens with crossed eyes too. :lol:

Not a Number, really nice stereo image....
I've seen some before, and that one is one of the best I have seen.
Some really lack a wide focal plane, and look just barely 3D, but that one looks fully 3D.
It looks like I have a pot of gablripes sitting on my keyboard.

What is your technique for making them?

For the people who have trouble seeing it, they can be really hard to see if you haven't done it before.
Just keep trying, and you will get it eventually.
It is easiest if you are not right up next to the screen, but rather 18" or so back from it.

To present a stereo vision effect (aka "3D") you need to present the left and right eye with images take at slightly different angles. So basically take one photo then shift the camera position to the right or left about 2.5-3 inches (average distance between the centers of the human eyes). With a small subject I use a tripod and a focus rail. The rail is set so the horizontal movement is perpendicular to the subject. Exposure, zoom should be the same in both photos - use manual modes. Everything as much as possible should be in focus, horizontal lines should be parallel with the top or bottom frame line, vertical position should be the same in each frame. You may have to fix this in post-processing. Paste the "left-eye" image on the left, the "right-eye" on the right. If you don't get a stereo effect try swapping the positions. If properly photographed flipping back and forth through the right/left images should appear to be rotating slightly to the right and left.

You can do the post-processing in most photo-editors such as Photoshop and/or use StereoPhotoMaker (freeware) which has some nice tools for aligning and cropping the image. Exposure, level adjustment and sharpening is better done in Photoshop or whatever. You can also create "anaglyph" 3D images - but you need red/blue or magenta/green eyeglasses to view them. StereoPictureMaker will make interlaced photos for use with "shutter" eyeglasses with some Sharp monitors (the system 3D TV monitors are using).

If you have trouble crossing your eyes try making a frame with your hands and holding the "frame" less than halfway between your eyes and the monitor. Focus on the frame and move it back and forth until you see the stereo image.

Here's the presumed hybrid D. ultramafica × spatulata. I think the effect works nicely with this one.

Wow, that one is great...
I just made one (by hand) of a D. peltata. I'll post it once I resize it (from 2.2 MB). It is a bit harder to line up than yours are.
I also made one of a capensis leaf, but again it is more difficult to form the image, as these pictures were not done carefully.

OK, I've got the pics on photobucket.
Here they are:

Drosera peltata:

You need to tilt your head a bit for this one.

Drosera capensis:
Stereo_Drosera_capensis_Small_zps36ec1217.jpg

Focus on the bottom part of thie image first. The alignment was not very good, and the leaf bends toward you. If you get yourself oriented on the bottom section of the image first, it is much easier.

I tweaked these a little in StereoPictureMaker. I did some vertical alignment and swapped the left and right images on both and moved the D. capensis a bit closer together. You can to some extent control where the virtual fore/background is with the horizontal separation.

I found an app that makes these super easy to make.

D. ramentacea (or at least i'm pretty sure it's the real thing).

Drosera hamiltonii deep pot test - they seem to color up best in the winter - more response to red (or is it blue in winter) end of light spectrum? I've noticed the same with Cephalotus which grow in the same areas in Australia.

Thanks for the instructions for 3-D NaN. A very cool effect. I especially like the way the resolution increases in the viewed image.

@GemStateC - Those are some nice-looking plants. 'Don't see D. ramentacea often. 'Reminds me strongly of D. hilaris.
 
  • #312
@bluemax - Thanks! I was a little concerned it was D. hilaris at first.
D. tomentosa hairy and glabrous flower stalk forms:

And happy almost Valentine's Day. Compliments of D. 'Dork's Pink'.

I hate to muddy up such sweet photography in this thread, but I'm gonna do it anyway.

'albino' x aliciae

I call this little number a big mess.

How many dews can you spot in this pot?

'albino' x aliciae from a different angle. Look at them stipules!

D. capensis x aliciae has such robust leaves!
D. prolifera flowers: It looks like some pollen actually made it onto the stigmas. I'm not sure if this plant can self pollinate but some seed would be very interesting.

Communis var breviscapa (spatulata??). It seems to need more light than the average sundew to color up.

I repotted my Drosera Adelae, and found 5 small plants growing off of the roots. :)
