Just did a quick test using blacklights in my lightbox. From left to right:
Standard Lighting, Standard Lighting + Blacklight (and digital editing to remove the purple discoloration of course), then Blacklight only.
The edited blacklight looks a little less natural, but the eyes look much more alive. IDK, maybe I'll use it more in the future, maybe I won't. Any thoughts?
Testing Metropolis from Lomography. I love the desaturated vintage look.

Just some test shots with my new Canon 80D. Taken near my home in North Lincolnshire. Not much to take pictures of around here, as the ground is so flat! Light's terrible. But I tried to make do!

Electronic gain for R,G1,G2,B channel of D810a Bayer matrix is measured following approach described in the article of Craig Stark "Signal to Noise: Understanding it, Measuring it, and Improving it: Part 3 - Measuring your Camera".
Electronic gain is different in R,G1,G2,B channels, the highest in B and the lowest at R.
Relations of gains for different channels don't change with ISO.
ISOs for that gain is equal to one is calculated for each channel. According to results, there is no reason to use ISO higher than 600 (say ISO 640) in astrophoto. Above it we will get truncation of the dynamic range of the shot without any benefit in signal or S/N ratio.
Healey Mills to marsden MGR wagons, nice day for December, with dry rail / good conditions.
Loco ran round at Marsden, train returned to Healey Mills, success.....
Come 1981, when the Woodhead Route closed, these MGR's were a regular sight through Huddersfield, heading for the Fiddlers Ferry power station, at Warrington.
Often overloaded, and on a wet rail, chaos usually reigned for many an hour, as they failed to make the uphill struggle to Marsden. Stranded passengers everywhere, while their trains were diverted up the "Lanky" and just a few local stoppers to Leeds with no taxis / buses, or backup plan, it was awful, and it happened regularly.
A class 37 was on standby in platform 7, when this photo was taken, and 56 006 had a brake van marshalled, at each end of the wagons.
Looking at this now, it seems as if BR had the woodhead route stitched up already, even though it did last until 1981.
