Check out this cleverness:

[F]ashion retailer Ted Baker is making insanely innovative use of Instagram filters to deliver hidden messages people can use to win prizes. This is all to promote its new SS15 collection.

Over the next two weeks, working with Poke London, Ted Baker will upload specially-processed images to its Instagram account. The brand is asking people to re-gram or screenshot and re-post the images to their own Instagram accounts. And then by applying filters, various clues, hidden messages and challenges appear in portions of the image.

Steganography for the rest of us!
