Overview
GotPhoto's QR code system is really helpful for keeping your photo jobs organized., so it's important to take your QR code pictures in a way that makes sure the system can read them easily. In this article, we'll review the key to shooting easily recognizable QR codes, as well as some common mistakes to avoid.
Shooting Guidelines
There are three key elements to taking a good QR code photo:
- The card should be flat.
- The photo should be evenly lit.
- The code should be in focus.
If you keep to these guidelines, your codes will be recognized by the GotPhoto system.
Some further things to keep in mind:
- Size: The recognition is done on a 1200px scaled photo. The dots of the QR code still need to be recognizable with that image size. The code can even be as small as an edge length of 15% of the photo (2% of the image area).
Our recommendation is to shoot a close-up of the QR Card so you can still read names, access codes, and/or handwritten notes on each one. - Positioning: In order to make sure that the QR code is flat, we recommend using a clipboard.
- Siblings/Buddy Shots: The GotPhoto platform can recognize up to 5 QR codes in a single image, making sibling or buddy shots a breeze. Make sure you meet the rules above with all QR codes in the image.
- Backlighting: If you are holding cards by hand, make sure not to backlight your cards!
