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)
finally got my little lens adaptor that allows me to use my dad's gorgeous old Pentax screw-mount lenses on my Canon DSLR -- and what a difference a lens makes! tried to shoot the same scene, a few minutes apart, both 50mm lenses and shot at 1/100 at f2.8 -- yet there's a huge difference in how they look! Canon "nifty fifty" 50mm f1.8 is the top image, Pentax's Super-Takumar 50mm f1.4 is the bottom...

Lenny has a new way of drinking lately, which involves dipping his paw in the water and slurping off of it.
Just testing a new method.

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!
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.
The crawler-transporter 2, with NASA's mobile launcher atop, makes its way up the ramp to the top of Launch Pad 39B at NASA's Kennedy Space Center in Florida, on Aug. 31, 2018. The ML will undergo a fit check, followed by several days of systems testing. The 380-foot-tall mobile launcher is equipped with the crew access arm and several umbilicals that will provide power, environmental control, pneumatics, communication and electrical connections to NASA's Space Launch System (SLS) and Orion spacecraft. Exploration Ground Systems is preparing the ground systems necessary to launch SLS and Orion on Exploration Mission-1, missions to the Moon and on to Mars. Photo credit: NASA/Cory Huston
Under threatening skies, QR 2474 leads 700 Series EMU 701 south through Dakabin on the Northern Line as Departmental Train #4U80 (Maryborough West to Wulkuraka Maintenance Facility). EMU 701 has been conducting various acceptance tests between Maryborough West and Bundaberg over the past few weeks,
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.
