When I printed these out as 8x10"s for class, I found they were a challenge for some people to see. Not everyone could pull off the 3D effect. My husband finds them difficult. Maybe it's because he has astigmatism, but that's just my theory, frankly.
I discovered, rather by accident, that I could see those old fashioned images created for stereoscopic viewers, just by focusing beyond the image itself, requiring the same concentration given to those magic eye posters in the 90's. You need to keep your eyes level with the image, and stay still until it "pops" into focus. Either cross your eyes to slowly bring the two photos together, or try to focus on a depth beyond that of the image. Everybody's screen size and resolution is different, so view them on the smaller side; not larger than 7" across.
I found one trick is to position your screen at your arm's length away, actually put your finger tip at the bottom, center of the image (below the white, vertical line), then raise a finger on your other hand at elbow or forearm level (of the extended arm), focusing on the finger. Without changing your eye's depth of field, you should see that the two images beyond have now combined into one. Your eyes will be slightly crossed. Whew! Weren't expecting eye exercises today, were you!?
I actually think the effect is better if you look beyond the image, like 50 yards, but apparently I've found a weird talent that I will never find any use for beyond my own amusement.
There are actually 3D cameras out there, but these were taken with my trusty Canon by taking two shots, one step to each side, then making sure they lined up horizontally in potato-chop. For tabletop, shots, I only moved a couple inches left/right.
All that said, it may be that all you see, and all you'll ever see, is two similar images next to each other. No big deal. Sorry for the workout. Instead, please enjoy them for what they are. An April weekend in Wisconsin.
Should you want to view these in different sizes, here is a link to the set. The triple circle (ooo) icon on each individual image's far right, features on All Sizes option. Just an FYI for anyone's image you wish to see larger.
BTW, happy Friday!!
