HELMUT Film Scanner


Helmut is a photographic film scanner on your phone.


Usage scenarios
* NEW: capture frame using phone's camera, or use an image from Gallery (e.g. taken with your DSLR).
* Digitize your (old) negatives.
* Share your (lomo) shots easily without format or film type restrictions.
* Fast contact sheet tool.

Features & Instructions
1. Place and press a negative uniformly on whatever you like (see section Lighting the Film below).
2. Launch Helmut and capture the frame, or choose already captured image from Gallery.
3. Crop the frame.
4. Tweak the scan with tools you're used to work with while scanning:
* Brightness/Contrast.
* Levels (General, and all 3 RGB).
* Color Balance.
* Hue/Saturation/Lightness.
* Unsharp Mask.
5. Flip, rotate, and share! So far we've implemented 3 services to work directly from the app: Dropbox, Facebook and EyeEm. You can always open the resulting scan in a native Gallery and share elsewhere from there.
6. See our set on Flickr for visual inspiration: http://www.flickr.com/photos/88137108@N06/sets/72157633282298542/.
(7. Spread the word about the app, share your successful scans!)

General Guidelines
* Make sure you light the film frame uniformly. If part of it is lit more than the remaining area -- you'll get a poor scan.
* Don't use flash or any color effects while capturing the frame with the camera. Yeah, right. Common sense. Just sayin'..
* Crop the frame accurately, leave out the film perforations. The colors will be more accurate then. Everyone knows it's a film anyway.
* Be nice and report (see email below) if something doesn't work instead of exploding here. We know it's not perfect. You know that technically it's very challenging. This is an open-source initiative, so participate. If you know a way to improve Helmut, please tell us. We will implement all the valuable ideas.
* If possible, be sure to press the frame against the light source. Poor man's solution -- simple glass. Anti-Newton-Ring typish is, of course, more suitable.
* Also, try eliminating other sources of light. Put your main light source (see next section) into a box with a single hole for a phone lens on top of it. This fixes the excessive contrast or color cast in the resulting scan.

Lighting the Film
Again, no matter what you use, make sure it's lit uniformly.
Here a list our ideas for a light source:
* Your laptop screen with an empty Notepad window (and turn on max brightness of the screen).
* iPad, Tab, any tablet with some lightbox app open. Or just plain white screen.
* Your window pointing to the sky.
* Google "DIY film lightbox". Add "lomo" to the query.
* We are working on creating several budget open-source lightbox versions. Something you could build easily on your own; or send to some 3D/laser printing service to cut the pieces which you could assemble manually. We will publish the sketches as soon as they're ready. Any creative suggestions are highly appreciated.
* Use some commercial solutions, e.g. a recently release black box by the well-known producer.

Known Bugs
* If the app is crashing after you capture the frame -- try lowering the 'Scan Quality' in the app Preferences. Our aim was to make as large resulting scan as possible. We therefore push the memory limits and for some phones that's simply too much.
* Currently app only works in portrait orientation.

Permissions Explanation
* Camera: for capturing the frame.
* Storage: for saving the scans and intermediary files.
* Network: for sharing the scans.

All in all, stay tuned. This is just the beginning. We have a lot more to offer in the project. Be sure to check http://HelmutApp.com for updates.

Have fun, boys and girls! Let's keep the film alive.

Recent changes:
* Tweaked auto-adjustment algorithms.
* Stabilized cropping mechanism.
* Minor bugfix when loading a preset with adjustments in Levels.
* Added support for more tablets.

SO cool! This app is so cool! I'm thrilled that there's one for Android, given that there are various ones for iOS (but none that work on my hand-me-down iPad from work). One minor issue: when I try to upload to Flickr, it opens the web browser and asks me for permission to allow the third-party app to access my Flickr account every time I try to upload to Flickr, even if I accepted before. The acceptance doesn't seem to "stick". The Helmut app says my account is linked but it can't access Flickr to upload anything. I have the Flickr app on my phone as well and that doesn't help, though I can upload through it or from the Gallery into Flickr. Am I doing something wrong?

Takes a very long time to download. Once you take a picture of the negative the 1st preview can look great but once you accept the picture is then goes slightly out of focus automatically. The final picture is not great but it was nice to see all the same. Sorry I don't think this app is all it makes out to be. Waste of time & and will uninstall it.
