What are some tips for capturing highest quality close up images of documents that will be processed by a document scanner app like Droid Scan?
Tip: before you begin, make sure you are using the right settings:viewtopic.php?f=7&t=64
Capturing photos of documents is a type of "macro photography," and learning about that technique will improve your document captures. A tricky aspect of this type of photography is that it exaggerates some problems that are less noticeable in casual photography (outdoor scenes, group portraits), especially:
- focus issues
- motion blur caused by camera shake
- lighting problems
The good news, though, is that cell phone cameras are getting better at this type of photography, and even when your camera can't capture the optimum image automatically, there are techniques you can use to greatly improve the results.
In the area of improved camera software, many camera apps now feature a macro mode that you should explore. This will help with focus issues.
In the area of improving your own technique, the two most important topics are lighting and camera motion. Lighting: Diffuse bright light works best, flash is always an option to consider in poor lighting conditions, and your camera app has exposure settings that you can experiment with to improve definition in the capture.
Camera motion: this becomes crucial in close up photography. If you need good results but not production quality results, learning how to use spot focus and how to press the shutter without shaking the camera will be enough. See the links below for more details.
If you need the very highest quality results, a tripod or a rig that supports the camera is recommended, for example a Gorilla Pod.
