I was saddened to learn some months ago that Dr. Masessa perished in a crash with this aircraft. It happened in 2019.
Sometimes a bunch of flowers are just in the right place :-)
The scholars think they were burial vessels.... but who really knows?
I used to do this with a lcd monitor, where I removed the lcd panel and some of the filter screens. The monitor is resting flat on it's back. On that I placed a glass screen on which the negatives were handled. This worked very good and the monitor gave a good and evenly distributed light curve.
Lately I switched to a Kaiser Slim Plano Pro (the large version) because I want to construct a XY cross table so I can lock a movement axis and make a holding mechanism that fixes the negatives to a frame. The monitor is too heavy for that.
When you buy a LED panel I would advise to only look out for those which have a color rendering index (CRI) of 90 or higher. The panels with no index or lower have a "light bias" which makes the camera record wrong colors, and this is hard or impossible to correct in post processing. This is also pertains to b/w negatives.
The camers is fixed to a full cage and a Kaiser repro stand (like an enlarger). Mounting the camera in a cage opens up the possibility to switch sides on very large negatives, like 8x10 sheets or glass plates, which is important for multiple exposures for the same negatives.
Postprocessing: I load them into Photoshop, merge them if multiple exposures had bee taken, convert to 16bit, convert to gray, run the CF Systems Colorperfect filter over them (it does a good job inverting them, bw and color), then do spot healing on dust spots and scratches (this is way faster as in light room). In light room they are catalogued, cropped and aligned, if necessary, and maybe doing a little contrast or light/dark adjustments. And then exported. That's it in a nutshell.
