I found a 'gotcha' if you use LED light bulbs as a light source.... when your shutter speed gets to around 1/60s and faster, you start to get banding! Best to stop down and keep speeds to 1/40s and slower.

General purpose LED's can certainly do this. Fortunately the easy fix is to use either flash or an LED light that is designed for photography . No banding, high CRI, adjustable output, portable, battery-powered, flat even light source when diffused, most have adjustable color temp, tripod socket for mounting.

My favorite lights are the compact Aputure LED panels that I got from B&H...

Amaran AL-F7

They use the common Sony NP-F lithium batteries, or can be powered via USB-C (but output is cut in half). They also have a D-Tap input if anyone has a D-Tap video power pack.

When you're done duping, you can take these lights (I have 2 of them) outside for shooting macros, or use them for video, or your "favorite" Zoom meeting!

1/40s:

1/125 second (banding visible)

Both those images are from Kodachrome slide film, taken in 1959. That film is nothing short of remarkable. All the old E-6 color slide film more than 20-30 years old are fading, some badly.

Yup, time is a-tickin away! Good luck to you!
