Tips and tricks for taking quality photos using your Android and iPhone?
Lighting Conditions: Bright but indirect light is best. Placing the check too close to lighting sources may cause shadows.
Background surface: Any surface of a solid color that contrasts with the check is best. Use a dark-color surface for light checks; a light-color surface for dark checks.
Document Zooming: Make sure that the bottom of the check is aligned with the base guideline on the camera when taking the picture.
Image Size: Use the green guidelines to properly zoom and scale. Make sure the entire check appears in the guidelines and fills the space as much as possible.
