I had to look this one up as I had never heard of it. Interesting idea of vibrating the negative but I'll let anyone else interested do their own research. There were even videos which unfortunately did not seem to connected to the Adams machine and were about as much use as a chocolate teapot in terms of "how to"
Someone with patience and looking to learn a new skill might well benefit from this machine. I suspect bigger than 35mm negs are almost a sine qua non even for the most skilled retouchers
