Light Box Loupe is the easy iOS solution for proofing and saving film negatives (and reversal film) in real-time.

Light Box Loupe allows you to take advantage of the iOS device's large screen and imaging capabilities to view a magnified positive image from original film negative or positive transparencies. It allows you to see the film images as if a proof print were made and then save the live view result to the Photos App on your device.

Light Box Loupe also has light box functionality as part of the App. Working with two iOS devices, you can set one in LB mode to have a uniform white, light box surface to backlight your film material and then with the other, a magnified live view viewer to evaluate a nearly correct positive black and white or color image.

Light Box Loupe is useful in helping to view and organize large quantities of film material without the need of a proof print or scanner. It is not meant to replace film scanning but help in organizing quantities of film images for later high quality scanning and preservation.

There may a lag in physical device movement and the corresponding image updating on-screen. This is due to the use of motion stabilization to aid in steadying of any sudden movement while viewing.

Please move the button!

I really love this app, but PLEASE move the picture taking button to the bottom of the screen! Then you can easily snap a pic with one hand. This sounds dumb, but I like to use this app while the negs are hanging to dry, so I use an iPad as a LightBox in one hand and my phone with this app in the other. Also, unless you are left handed, you put your hand in front of the image while you are taking it. Otherwise, I LOVE the function of the app.

Great Negative Viewer!

This app is very useful to view negatives on the fly! It also helps if you have an iPhone and iPad with the app installed in both, so you can use one as a light box and one as the “loupe” viewer. Only criticism is the camera lags a little; doesn’t quite meet real time playback.

Very useful

I’m always inverting my colors on my phone to view negatives. This works great. Gets the job done for a proof. The camera is a little slow, you move your phone then the image catches up, and the icon to take the photo could be in better thumb reachable location. But it’s the only one out there. So cheers to that.
