In an earlier post, I mentioned how Quick Response (QR) codes appear to be not used to their full potential, especially in terms of photography. 

A QR code is a small square, made up of black and white squares. Similarly to a bar code, the. QR code can be scanned and link to other relevant information.  

If the QR code was part of a photograph, then it could be perceived as an invisible layer. I like the potential it could have for enabling the viewer to interact with the subject at s deeper level. This could include revealing a map of the photograph's location, or an audio clip that would provide a narrative. 

Despite these apparent advantages, having a black and white square on the photograph would obstruct the viewer from appreciating the image in its entirety. Ideally, I would want the QR code to be hidden.
