Thanks Hannah! All you need is regular 35mm film. The camera will make two images, side by side, on the regular film. You will need to scan each image, and label them carefully, to feed into the software to make stereo viewing cards.
I’m glad this resource is useful for folks.
Regarding my development methods with Diafine, at it’s simplest I develop for 5+5 and use continual roller agitation.
My more detailed response is to consider time, temperature and agitation.
Hi FVZZMAN,
My dad and I both use antique Holmes viewers to look at our cards. The viewing quality and user experience of a Holmes viewer is excellent. It also means we can use the same viewers to enjoy antique Holmes cards in the same way.
