It’s Christmas for crypto users today! Imgur user crazyflashpie has posted a super easy tutorial on using channel colors in Adobe Photoshop to hide keys in any photo. Additionally, he has a beautiful 4k-ready image of every coin in the world, available freely for anyone to use.
“I was tired of seeing physical coins anytime an article about Bitcoin emerged in the press. This artwork cointains coins from all over the world (There are even 21 casascius bitcoins in this image).”
It also lives Creative Common’ed on flickr https://www.flickr.com/photos/crazyflashpie/15261748371/
Update: If you like this, you might also like stenography, where you can hide images inside another image. There’s a Chrome plugin for that here: https://chrome.google.com/webstore/detail/secretbook/plglafijddgpenmohgiemalpcfgjjbph and another photoshop tutorial https://www.youtube.com/watch?v=4AQLpxzJF8A
