This is totally off on a tangent, so feel free to ignore:
After struggling with slide scanning on an Epson V500 for years, and generally getting lousy results (loads of chromatic aberration, poor detail resolution despite plenty of pixels, and bad color) - I decided to try to photograph them. The setup is simple. D800, Micro-Nikkor 105mm with extension tube, small piece of diffusing plastic, flash backlight. And some tape to hold it all together.
Wow.
The result is razor-sharp with all the fine detail I have always missed, totally clean from CA, and with a few quick Lightroom adjustments it's there. Previously I had to bring them into Photoshop and spend hours.
The scanner is outside my window if anyone needs it...
