Pinhole Assist

I've used this app for a couple years now, and have seen many improvements over time. The combination of having a whole lot of camera presets built in, along with reciprocity failure calculation for a huge list of films, there's not really anything more I could ask to add. This is an absolute must have app if you're serious about nailing exposure in some tricky situations. Very, very flexible and adaptable to just about any scenario!

Really like this app

This is my go to app for pinhole photography. I just started playing around with pinhole cameras about a year ago and this has made getting good results much easier, especially because it takes reciprocity failure rate for whatever film you’re using into account. The only other option I wish it had was the ability to key in “normal” exposure settings from a handheld light meter or dslr test shots and convert it to your pinhole exposure settings. Regardless, this makes pinhole life soo much e

I’m relatively new to pinhole photography. Currently using Thingyfy lenses on my EOS 5D MKIV. I tried out this app for the first time today. With all parameters set correctly, I was able to get good exposures the first time. You have to covert the aperture diameters to f stops. Then you are ready to go. I was able to get good images with long exposures at ISO 100. Very pleased. Thanks.

I really like this tool. It saves me the trouble of figuring out the exposure time given the small aperture of a pinhole camera. However, it does crash every single time I try to add a film (when I edit the reciprocity correction table). This is very annoying.
