The folks from the Kloke Locomotive Works taking their latest creation the steam engine York out for a test run on the Fox River Trolley Museum's tracks. A work platform on the locomotives right side allows a couple of technicians to adjust one of the pistons. One of the crew on board said she was running so-so. Understandable since she only has a few miles on her after being shipped from the factory in Elgin This is absolutely the newest steam locomotive in the United States, and quite possibly the world. Thanks to the heads up from BasicBill and the wagonmaster on this event

Update (2015-02-09)
I did new tests:
www.photigy.com/best-focus-stacking-macro-rails-vs-focus-...
*/
This is a quick test to compare the results of two focus stacking approaches:
1.)
For this one, I did two shots and changed the focus between the shots.
First one: Focus on the front pin, second one: focus on the pin in the back.
Then I copied the (sharp) front pin near the pin in the back. One can easily see the large difference in size. If you want to do focus stacking this way, then it might work (the programs tolerate size up to some degree), or it might not.
2.)
For this one, I did two shots and changed the distance of the camera between the shots using a macro rail. One can easily see, that there is no difference in size. A good basis for focus stacking.

So, a macro rail is a cheap gadget, but does a good job to provide a good basis for a stacking series for focus stacking.

The pathfinder (or test) backplane of the James Webb Space Telescope is shown here at NASA Johnson. It's secondary mirror boom was extended in prep for cryogenic tests in NASA Johnson's giant Chamber A. Mounted on the pathfinder are two test primary mirror segments, and at the end of that boom structure, a test secondary mirror.

Test runs continue with Class 701 units on the Bournemouth main line, but still no firm idea when they will enter service. Here 701010 passes Christchurch on a run from Eastleigh to Bournemouth via a run round at Basingstoke on the 4 February 2023. Grotty weather conditions, but the new Z30 coped just fine and works well at higher ISO settings.
More tests today. I'm learning how to control very light values. But first I did a little ink test in the upper left to see if you get green when you mix yellow and black ink. Yes, you do if you are very fast and mix them while they are still wet. I used a yellow Micron pen and a black Zig pen.
My main test was to slowly build up dilute colors. I had burnt sienna in one Kuretake Mini waterbrush and cobalt in another. I applied a wash, waited for it to dry completely, and added another. I did this four times to create four increasingly darker values. You have to be very patient, but it works. I learned this method from a book called "The Wash Method of Handling Water Colour" by Frank Forrest Frederick published in 1908. I found it for free on Archive.org

Where you can download it as a PDF, ePub, or Kindle file.
Finally I tried to get the lightest value possible with a number of colors. I used a wet round brush to pick up a little dried tube paint. I then quickly dipped the brush in water, tapped the brush against the inside of my water container (to dislodge a little water) and then made a brush mark down the dry page. This deposits very little pigment and is a good way to make beautiful, light colors. I also tried lifting some color out with a thirsty brush (in the cadmium red/lemon yellow mix), and I tried adding a little more color on top of the wet first stroke (ultramarine and cobalt - bottom left).

Testing out lith-printing on paper. This is the best so far, still somewhat uneven but usable i think... Its an art that takes a time. to practice due to the fact that you have to pull the print out of the developer at the right time.

I failed to focus a camera...and I'm badly done...sorry.

A test shot done of Kina (renamed Gwendolyn Giang),that's why her hair is Blah. I wasn't planning on posting this; but the angles and little editing I did came out waayy too well not to.
Did some High ISO test today. Results are pretty impressive. Here are the Exif data.

Just something about this light and background test shot before we got into the shoot. I was going to toss out but kept coming back to it and decided to post. Taken at Freestone Park in Gilbert Arizona.
Taken with a Canon EF 200mm f/2L IS USM lens and Canon 5D Mark II Camera. Shot wide open at F/2.

A small test piece I created to test the slat deployment mechanism. The challenge was translating push-pull spanwise motion to chordwise motion. The solution was creating spanwise stip that pushes thin strips of paper along a curved (90º) paper track. The resulting mechanism makes for incredibly precise and synchronized motions across multiple slat tracks at the same time (=SUCCESS!)
