Like the weekend, little focus and much of it was a blur - LED strip on a printed circuit board. These were rapidly superseded by strip circuits on sticky-backed tape that can be easily cut to length, are much flatter, and have better colour matching of the LEDs - the above seem to vary even along this short length.
Had a purge on the eight remaining films from 2019, and they've now been digitised via a camera. Batch edit stage done too. The individual editing, tagging etc. will take an age, but glad to have finished that first awkward stage. Wet out, so a good day for such work.
