Things I’ve discovered

I bought an Olympus OM-1n camera to get back to hands-on, manual B&W photography. This would also allow me to use IR film for infrared photos and is far less expensive than buying a second mirrorless camera and having it converted to IR, and buying the filters it would need.

Here are notes and thoughts on IR photography, principally on film. I may update this article every now and then.

Film or digital

Why not both?

It’s easy to add an IR filter to a smartphone. You could continue taking IR photos that way, but I find this is a neat way to preview a scene, and check whether it’s worth taking a film photo.

You’ll need the IR filter (I compared three in this story) and a way to attach it to the phone. The best way is with a magnetic holder. A more complex way is with some type of phone shell that allows accessories to be attached. You’ll have to search Amazon…

A holder I made is shown above with a scoop cut out from a magnetic ring, and a 39mm to 58mm step-up ring epoxied to it. The step-up ring has a hole cut out, to tightly match the lens box of the iPhone…
