What I am saying is , even if this lens pair with 12.5mm separation is used on a full frame sensor, the image width at the central portion of the sensor will not change for both pairs. Therefore the

Note that images sent or uploaded to the group are resized to a maximum 2048 x 2048 (our chosen group setting). Original size was 3888 x 2592 (1944 x 3593 x 2) on according to the exif data. These

I understand, the person in charge of codifying the 4k standard declared there will be no 3D option in it. John M. Clement

"I doubt the increase from 1824 to 1920 would be due to the increased width at 16:9 ratio." Agreed, because 1920 is the width of the 4:3 image anyway. We do not yet know the width of the other aspect

The above graph has almost identical values as my calculations except the 1:1 ratio where I mistakenly did not consider the sensor height. The slight difference is due to my assumed sensor size of

Same old, same old. Why did the 3D TV come to an end? 3D movies that started in the fifties? Stereoview cards? It is just a commercial thing. A new gadget to sell. Now its 4K or whatever. The large

John, the idea with the "multi-aspect sensor" is that there are some "extra" pixels that are not counted in the 16mp (overall sensor is really ~18mp instead of 16p) but the camera uses them where it

Ok, here are shots with the Loreo Macro 3D lens. Hope they go through, they were quite large, upt to 14 mb. You can get pretty much the same good results with both lenses, if you put your mind to

Sensor size and imaging area are different. Sensor size relates to the physical dimensions of the sensor itself, not it's imaging area.(wiki) The sensor of a 4:3 camera measures 18mmX13.5mm (22.5mm

According to the eBay listing here was a set of 250 signed copies and then additional ones printed for the trades. I didn't think it appropriate to post link to the ebay listing here but you can

I do have a copy in my collection. However, the quality of the pictures is pretty bad. All original books should be signed and numbered - but there are a lot of re-prints out there ... Alexander Am

Anyone familiar with First Impressions of America by TC Porter(1899)txt w stereorscopic pics+viewer? Flat wooden viewer included inside book. Authors claims just 2nd book produced with stereoviews.

These are variable magnification 3D Macro lenses that I produce manually. Oktay

"Classical painters frequently attempted to convey the element of the third dimension through the use of 2-D depth cues, such as perspective and shading. Such attempts were unsuccessful, but pointed

Has anyone here owned/used or otherwise familiar with the 8 lens 35mm Fuji Rensha Cardia camera for lenticular?

These are two of Ronald's attachments that did not go through (for unknown reasons). These were taken with the Pana 3D lens. Linda

Do you think acid from the book pages may have contributed to the print fading or is this just the nature of albumen prints?

Check the link in my posting about callotypes (from a post card website). They show original full size images and a couple different levels of magnification shown the random pattern.

As Linda says, using 1:1 aspect ratio is useful for Stereocard views. I would also add that it is purposeful for side-by-side viewing on mobile phones and at the Zoom meetings; my own needs are
