Photoshop instructor Unmesh Dinda from PiXimperfect has come up with an interesting tutorial that shows you how to create and send ‘secret’ images that can only be viewed by the intended recipient, using Photoshop. The image will be a blank PNG, unless the recipient opens it in Photoshop and follows the necessary steps.
If you want a higher level of encryption, the tutorial shows you how to create an Adobe color table file (.ACT) that acts as a “key” to decode and reveal the image. Watch below.

03:14 – Saving your image
03:56 – Decoding the image
04:28 – Method 2: Advanced encryption
