What's the largest you've had printed Gary?

Gene did a poster 8 feet x 6 feet for in a Florida airport. This was the biggest we have done. Amazingly, some people could actually see it.

We had one request to do a two story high ceiling in a building atrium. We quoted an outrageous fee and did not get the job.

My maximum is 4" x 3" which is as big as I like to go.

Interesting, I'd have thought the bigger the easier it would be to see.

personally I think there is an optimal ratio: size/distance from, which will vary from person to person

6 by 6 I would have to stand back quite a bit

Not so. Your eyes need to pull together the repeating panels. And the wider the panels the harder it becomes.

The attached: The first two circles (when viewed full size) should be pretty easy for most people (sorry Chris) to pull together.

I have to work to get the next two to come together.

The third pair I can pull together but it is not easy.

My stereograms that are basically designed for 10" x 8" viewing use a repeat that is either 1 1/2" wide or 1 3/4" wide.

The biggest advantage for a poster size image is you can get more detail to the hidden image. But the repeating pattern becomes more obvious and less random.

Thanks for that info Gary. I get the attached image quite easily.

I get the attached image quite easily.

Full size, not the thumbnail? If so you're better at this than I am.

Odd. When I pull the two in the middle group to make three, I see four on top.

This is what I see if I take a screen-grab Gary:

the full size is actually esier than the thumb nail for me

it would be interseting to try them as seperate images - with the full image they all 'pull together' so to speak for me, I cannot do them in isolation - and I see what egg sees

It depends on which two dots you focus on. For me at least.

Steve - I'll try to post a stereogram with different width patterns, though I will have to link since TG only displays up to 800px.

OK. I bashed this out. Same depth image, three different widths on the repeating pattern. 25%, 20%, and 15% of the width of the final image. I prefer to work between 15-17%

Put these on 3 separate pages in the same document at 1:1 and go between the images and you can see the difference in the repeating panel width. The page size is 960 x 768px
