Did you hear about the truck load of Viagra that was hijacked?

I started a thread a couple days ago looking for tips on digitizing old stereo cards. A request was made for samples so I'm uploading a couple by photographer H H Bennett. He was active from about 1864 to 1908 taking many landscape shots in the upper Midwest. His studio is now a museum in the city of Wisconsin Dells (previously named Kilbourn City as seen on the card).
I scanned these with an Epson flatbed, recovered details using the Nik tools as they were faded with age/sunlight, resized and converted to .jpg for posting.

Try contacting the George Eastman House in Rochester, NY. They have many experts.
You may have luck with a longer focal length macro lens at small aperture.

Thank you for the prompt. My copy stand is one of the old Ekatagraphic units but Eastman didn't occur to me.

I believe the reason for the curved cards was to increase the 3D effect, but not sure how that works. I would be reluctant to try to flatten the cards; they have been curved for a very long time.
The theory is based on the optics of the old viewers. The viewers have a simple magnifying lens with some amount of field curvature in their focus (never been measured to my knowledge.) The curve of the card is presumed to match the field curvature of the lens so the entire image is reasonably well in focus.
However, a couple years ago a stereo afficianado found some old photos of the Keystone factory showing the cards being processed in tall stacks, so while compensating for the lens may be part of the reason for the curve, the old photos show keeping the stacks stable was certainly a use for the curve.

I would consider flattening one image, slowly.
Put a book on top of the image.
A day later or several days, add another book.
Look at the image to see how it is doing (any cracking).
If this works, try another one.
I have no idea if this will work.
Just something to try.
I enjoy looking at these stereo images and I hope you post many!
I view these images using the crossed eye technique.

Thanks for the suggestion, I may try that with a duplicate card or two.
As a bit of background, the cards were apparently produced with the curve so when they came out of the production area they could be stacked and nest together to prevent the stack from toppling over. Flattening would actually be trying to reverse part of the manufacturing process.
In libraries, they use a repro camera with a digital back, but that would be a bit too much of an investment for a home hobbyist.

We use ours with the 1800's viewer as intended though.
Lots of fun and brings back childhood memories.

I also use the old Holmes viewer regularly, but as many of mine are fading with age I wanted to bring them into Photoshop and try to recover before they deteriorate even more.

Looking for ideas on digitizing old stereo cards. I have some that are flat enough to scan but others have such a pronounced curve that they can't be successfully scanned. From Googling a bit, I see two options:
1) Push down on the scanner cover until they flatten out. Being albumin prints, I resist doing this for worry of cracking or tearing the emulsion.In some cases there's 1/2 to 3/4 inch curve over the 3 1/2 inch height of the card.
2) Set up a copy stand with good side lighting and photograph the cards. Not sure if I can get enough depth of field to get good focus on the entire card so focus stacking might be needed.As I have a couple thousand cards that would be a major pain to photograph the entire set taking multiple exposures each and then combining the images.
The second option seems the most doable, but I'm wondering if anyone has tried this before and can share any pointers.

It will be interesting to see what comes out of the large gatherings at major cities these past few days.
On the network news just now, they said one of the Alabama pool partiers tested positive and was likely contagious while there. Possibly exposed hundreds as he moved from spot to spot during the weekend.
Also said Alabama opened 2 weeks ago and are now setting daily records for new cases.
Regional data, but interesting.

Well, that's no ordinary rabbit. That's the most foul, cruel, and bad-tempered rodent you ever set eyes on.

I have always been a Pentax fan because I feel I can get more bang for the buck. I presently own a K-3 and am very happy with it, but like to learn more so as to get its full potential.
I have own a Pentax 18-50 f2.8 lens, a Pentax 55-300 lens and a Pentax 18-250 walk around lens. Any feedback would be appreciated.

I use a K70 mostly with vintage manual lenses. Try www.pentaxforums.com for an active Pentax community. Lot of helpful people over there.

Interesting. Some said it is a replica car, but it has antique auto plates????
In Arizona a replica is registered as the year it's modeled after rather than the actual assembly date. Maine may do something similar.
I have a Mercedes replica that gets registered as 1929 even though I assembled it in the 90s.
