I have slides that are over 40 years old and it is time to digitize them, especially since NCECA is in Tampa/St Petersburg this year and I'm involved and will need to make a couple of presentations. So I sent 30 slides off to ScanCafe to see what they would do with them. I am happy with what they did and now I am going through all the slides I have from 1968 to digital, which is about 2002, I think. There are thousands.
This is one of a close up of one of my second year graduate school works. It is a slab built round pot, and you see the top. It was lightly rakued, a process I called "Smoked Raku." Its diameter is 16 inches. I will post some of the other ones from that period, including the firecracker pots and the flocked pots, as soon as the scans come back.
ScanCafe is inexpensive if you get lots of slides scanned, but the shipping is expensive for just a few. That said, it was worth it to just see what their quality would be and not commit hundreds of slides only to be disappointed. This image is clear, faded for sure, but I think it can be helped with Photoshop. It did not have much color anyway.
