Wow - why choose between cross eyed and red blue anaglyphs?!?!?! It's both!

(And awesome, too!)

Shaka - I had the same problem as you with the larger size but was able to cross eyes by focusing on the distance as james had... gorgeous.

I'll see what I can do Nico. smile.gif

Problem is that you need a colour pan from the right pancam, particularly because you are seeing both the blue and green channels through your right eye. I suspect then, that it is very important to have R1 (the only 'blue' filter on the right pancam) which not many pans have.

The other option is for us all to turn our glasses round the other way, this would make much more sense given the way the pancam filters are arranged!

btw: Gibson has R1 smile.gif pancam.gif

If the transcript of this conversation is unearthed by anthropologists in two or three centuries, it will be concluded that we are High Priests of the Occult discussing strategies for appeasing our pagan gods in order to achieve Enlightenment.
It's easier to explain it that way. ph34r.gif mars.gif

James: That is truly nice, and the colors come through in the anaglyph beautifully. My hat is off to you. I had no problems seeing the 3D effect, but I must admit that I work with anaglyphs so frequently that I sometimes think I no longer need the glasses. laugh.gif

I was particularly interested in what you have accomplished, because I have been working intermittently on some other color anaglyphs for several months now, and have learned that creating a good one is not a trivial task. I hit a roadblock at one point and enlisted the expertise of another member. We hope to have something to contribute soon.

James:

Beautiful colour anaglyph! It's like being there - it really gives an impression of the rolling nearby landscape.

It tends to fray a bit when you start seeing ghostly bits of MER in the foreground - why not try simply blocking out the 'confusing' bits, which might let the close ground work?

Hello smile.gif

I've just finish thge compostition of two panaroma from McMurdo Pan (it miss me two column of images to build the maximus of the pano).





The contrasts levels of each frame are not unified, I'll make this when the pano will be complete. wink.gif

Other details for French speakers here.

James, that's a stunning colour analglyph pan! I noticed that the impression of true colour improves as you observe it longer and longer, perhaps as your retinas fatigue to their respective colours (this is what leads to afterimages).

One question - what did you use for the right green channel? Did you synthesize it?

Thanks.

Your righ about the colour - it takes my brain a while to get to grips with mixing the different colour channels coming from each eye. blink.gif it does get better the longer you look at it. smile.gif

Yeah, it's basically a mix of R1 and R2.

About the problems with seeing 3D with anaglyphs - as someone said, the pancam channels are too wide apart, but the real problem is with the way of generating the anaglyph. IMHO the read and blue channels should be aligned perfectly in the center of the image to make a good anaglyph. I have trouble seeing real 3d with some images posted here - I see double. But when I take those "bad" anaglyphs and do some rough align in photoshop, the results are unbelieveable - especialy with this color anaglyph from james (10x!)

I think it varies from person to person, I made the colour anaglyph with the red and cyan channels aligned at the bottom as I find it really hard to see the near field in 3D otherwise. Maybe multiple versions are needed! blink.gif

I recommend Stereophotomaker to any one having trouble with pancam anaglyphs.
You can open an image and adjust the alighnment until you can see the 3-D effect.

Yeah - the anaglyph effect only works over a certain range I find - one has to coregister them on the point of interest - and sometimes that means you can get half a dozen anaglyphs from a single image pair
