Earlier this year I contacted a lovely company in Italy called 3DFlow that has developed some very impressive software called 3DF Zephyr. After using a trial version, I contacted them and they have very generously offered us an educational licence because we are a community archaeology group.
I know software probably makes many archaeology enthusiasts yawn, but this program allows you to take a number of photos from different directions of a find, a trench, building or feature and it automatically creates a 3D model that you can move around on your computer, tablet or smartphone phone and zoom in to see the details.
I tried it out last night with a series of photos I took earlier this year during CM418 with my digital camera. They were of the interesting floor feature in Trench W, made up of large R-B floor and hypocaust tiles. I am very impressed with the results which you can see by clicking here.
