Ok so this isn’t the best example, the top image isnt mine but basically that gap on the left of the frame (Its actually a reflection) is what I want to replicate. So the block colour will flat against the back of the frame, with the full colour print almost against the glass of the frame so you can look behind it. This will obviously require a deep edge frame – maybe near 10cm?
If this works there is also the possiblity of placing a small projector inside the frame, so it projects an image inside the frame behind the print. Will need to test somehow first!
