This is the third test roll I run in my old Olympus Mju II, a camera that I used to be very fond of for some years, although the point-and-shoot made me a lazy photographer without any control of any parameters. After the first two test rolls I thought the visible issue on the right edge of the frame was a light leak. So I shot this roll with all the possible sources of light covered with black gaffing tape. Surprise, the problem is still there and even more pronounced and regular. I haven't got the camera with me now to investigate but it will probably have to be seen by a technician.

Testing some lights with my brother. I like, do you like?
P.S. The EXIF data says 50mm, that's flickr trying to lie to you. It's actually and old Nikor 85mm f2. All manual homies.
Testing out a new blue background since I feel like everything in my photostream and yt channel looks too plain as all white. Don't worry I will still keep my legoformers with a white background to keep it consistent. (This also gives me an excuse to show off my old clone wars figs)
Testing my Cannon Rebel T3 with some apples. No photo editing done. Need to play around with shutter speed/Fstop.
Lenny has a new way of drinking lately, which involves dipping his paw in the water and slurping off of it.
To test the backlight I made a special arrangement. A glass plate containing a pattern. There is also a portion which is translucent. This allows me to test the influence of the background module. A part of the foreground exposure is in fact reflected. With different masks I measured this effect. The results will follow.

I met Freska today to discuss ideas for our upcoming shoot in a few weeks. During our meeting we did a few test shots to determine what type of lighting we would be using for the shoot. She works for FM 99.7NOW radio station here in San Francisco and is currently training for a Figure Competition that will take place in 3 months. Despite having our meeting right after her vigorous workout sessions that she has on the daily, she was excited and full of energy to have our meeting. She's such a nice person, I can't wait to work with her in a few weeks.

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.

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.
