Can't do a stereogram


This is apparently some sort of stereogram, but I can't do it. I have an easy time "doing" images like File:Stereogram Tut Random Dot Shark.png, but for some reason the same technique doesn't do anything with this picture, and when I focus my eyes normally, I can't see any of the repeating patterns that are generally necessary for seeing the underlying parts of such images. How is one supposed to see this image and others like it? Nyttend (talk) 02:10, 10 November 2018 (UTC)
 * This looks like one that you need 3-D glasses for, the color-based ones they used to use in the old 3-D movies, before they perfected the polarization-based version. Our article seems to be at anaglyph 3D, which is not a name I really recognize, but it seems to be the right concept. --Trovatore (talk) 03:52, 10 November 2018 (UTC)
 * Okay, I've never seen such a movie (and never understood what to do with the paper or cardboard 3D glasses), or maybe I would have recognised the situation. Thanks for helping me understand better.  Nyttend (talk) 05:21, 10 November 2018 (UTC)
 * FWIW, I have such a pair of red/green glasses (designed for printed images) to hand, and they work somewhat, but not very well, for the picture at either the size as rendered here, or larger as from the originating file.
 * It appears to me that the red components are 'overexposed' and/or have 'bled' beyond their original extent. I suspect somewhere in the chain of reproductions between the original and the image on my screen, the colour balance or some other dimension(s) of the image has/have been distorted. There may also be a mis-match between the colours used in and reflected from paper-printed 3-D photos versus those coming from a lit computer screen. {The poster formerly known as 87.81.230.195} 2.218.14.42 (talk) 16:11, 10 November 2018 (UTC)
 * I'm no expert but as far as I know, if you don't wear 3D glasses and you view a flat surface which is just an ordinary screen or paper and not a hologram then the only way to get a proper 3D effect is a pattern which almost repeats left-to-right, like in File:Stereogram Tut Random Dot Shark.png. It works when your eyes focus on different places but your brain is interpreting it as if they focus on the same place. A hologram works by emitting different light towards your left and right eye. This requires a special medium. 3D glasses work by filtering light so your eyes see different things. Virtual reality headsets work by having two screens showing different images to the eyes. Actual reality works by your eyes seeing an object from different angles. PrimeHunter (talk) 19:25, 10 November 2018 (UTC)

(I don't know whether there are different kinds of polarized 3D glasses or whether the design is standardized. Does anyone know?) --Guy Macon (talk) 17:22, 10 November 2018 (UTC)

can someone help me with a question regarding the BC Government?
Hi. I'm a disabled adult who lives in British Columbia and I get income assistance though a program called the ministry of social development. I'm wondering if there is a way I can expand my funding and I don't currently have a social worker. can someone please suggest something to me? Thank you!

 * This seems to be the place where you would go for such inquiries. I would start there.  There's a phone number for general inquiries, and there are also links that take you to locations of in-person offices where you can meet with someone to discuss your situation.  I hope that helps!  -- Jayron 32 04:46, 10 November 2018 (UTC)
