On the 4th and 5th of October we were in Kirkcudbright, Dumfries and Galloway, working together with the local History Society. Using photogrammetry we recorded selected tombstones in Kirkcudbright Kirkyard in 3D- and the results were fantastic! One of these was the headstone dedicated to ‘Billy’ Marshall, a traveler and ‘King of the Gypsies’ who apparently married at least 17 times and lived to the ‘advanced age of 120 years!’ Find out more about him on his Wikipedia entry here.
One of the group members, George Wishart has passed on this very helpful tip for sharpening stills from 3D PDFs, so you can get an image like this:
“3D PDFs do not open in Photoshop. However if I rotate the image to the desired position, I can then capture it using “Print Screen”. Ctrl v opens it in Photoshop. I can then crop the desired part to A4. That can then be sharpened. I like to use a duplicate layer with high pass filter in the duplicate layer which I then blend in overlay mode. The image can then be flattened and saved as a jpeg. Worked well on William Marshall.” George Wishart, October 2014.
Thanks George! Please do keep passing on tips and hints, either by using the reply tabs on the blog here, or email them to M.Maxwell@gsa.ac.uk and I will post them for you.
