This instructable shows you how to put an image inside a QR code and make it still readable.�
This instructable works with both Gimp and Photoshop, the instructions for Gimp are exactly the same, though the menus are different everything needed is in roughly the same place.
Or watch this video:
Step 1: Things You'll Need
- A computer with photoshop installed
- A smartphone or QR reader of some sort
- A QR code generator (here's a web based one)
- Images you want to embed
Step 2: Generate a QR Code
Or you can make them on your phone.
The shorter the code the better this technique works, mine's quite long.
Use the biggest size setting you have for easy editing.
Step 3: Open It Up in Photoshop
Go to image>mode>RGB
This is for the editing process.
Step 4: Add Your Image As a New Layer
Your image should be colour, but we'll deal with text first.
I chose orange and just put KJ, as in killerjackalope up.
Step 5: Making the Code Work.
Basically colours over 50% brightness as an RGB value lighten the image, under 50% darken, black makes black, white makes white. The reason this works is that a QR code is black and white only, so we only change the colour with hard light, not the brightness.
So it scans perfect.
Step 6: Images With No Black
Immediately it scanned.
Step 7: Photos From a Camera
This photo from of my coffee maker's gauge is on hard light mode at 60% opacity.
To get the opacity just right, hold the phone up to the screen and you'll see it trying to recognize points, slowly, very slowly lower the opacity until the image scans properly.
