It was suggested that I take a look at the work of Imants Tillers who produces large landscapes made of of small square pieces.
After blending the photos together in photoshop using layers I've printed that image out and cut it up. Next I've used similar shapes cut from old gift cards, white gel pen on black paper and magazine print glued to card. A few snaps of it in progress:
Ok, so the starting point for my next work will be some New Zealand mountain photos I took back in about 2003. It's something I've always wanted to work with.
