Here’s a little squirt of nostalgia into the brains of our (slightly) older readers: it’s an iPad app called Light Pad HD, and it exists to help you view your film slides and negatives by turning your iPad into a light-box. Instead of having to find a brightly lit piece of wall, or a window without distractions behind it, you can just launch this $2 app and drop your film strips on top of the iPad’s screen and use its screen.
This is one app that doesn’t care about Retina screen, but that would probably prefer the larger display of the iPad Air to that of the little Mini. It can work in several ways: you can have the screen light up strips to match the strips of ~6 35mm photos, as they come back from the lab, or you can have individual 35mm-slide-sized windows light up.
These can be toggled on and off by tapping them, and if you have an oddly-sized neg or slide you can just pinch to set a custom light size. Other niceties include in-app control of screen brightness, a new iOS 7 interface design in v2.0, and iPad mini support (to get those standard negative sizes correct on the smaller screen).
Light boxes aren’t cheap. Neither are iPads, but it’s likely that you have one already, which means you can replace yet another physical gadget with a $2 app. Available now.
