Segunda versión de una imagen previamente publicada. En esta ocasión hice un scaneo más completo usando la opcion "Raw" de VueScan, obteniendo una imagen de 16 bits sin nigún tipo de manipulación por parte del scanner haciendo toda la edición en Photoshop.
Primeros resultados de los experimentos con quÃmicos para color. Dado que no pude hacer el bleach, los negativos quedaron muy densos y difÃciles de scanear. La pelÃcula usada es una "KLICK" asa 200. La cámara es una Praktica L, con lente MIR 1B 37mm f2.8.
Scaneado con un Epson V600 y VueSan

just used a phone drawing app to make the effects but i need some advice here....so....yea....feel free to leave a comment!!!!!!!!
Testing the Canon EF100mm f/2.8L Macro IS USM on the Canon EOS 5D Mark II at Wooden Shoe Tulip Festival. Love the color and contrast of the lens. The hybrid IS and AF works very well. Shot a series of closeups handheld and all came out sharp. Too bad the lens belong to a friend. I may need to go get one myself.

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

GB Railfreight Class 92, 92 014 hauls a Caledonian Sleeper Mk5 test run south as 3Z11 Glasgow Central to London Euston through Acton Bridge.
Whilst there were some indications this would be a Load 15/16, there were only seven Mk5s in the consist behind 92014 - as was the case with the test runs the prior week. It was also the same short-formed "unit" of coaches, so at least some of them are getting some miles under their belts. The missing coach is believed to have wheelflats.
Rake was: 15006 / 15104 / 15203 / 15316 / 15324 / 15325 / 15329
(Missing coach: 15326)

Update (2015-02-09)
I did new tests:

*/
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.

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
archive.org/details/washmethodofhand00freduoft
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).
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.

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.
Developer kodak d8 diluted 1-4
About 2.5 stops overexposure (if i remember correctly).
Print from kiev 88 negative.
Band is Gete from Oslo.
I built this for the guys over at tested.com, as a thank you for having me as a guest on Octobercast 2013.
Testing Oblivion House converted to Skyrim with new textures, now I need to add glow to the windows so shine at night
The Board of Trade Inspection of the Irwell Viaduct over the developing Manchester Ship Canal. There are 10 locomotives of the Midland Railway and Manchester, Sheffield and Lincolnshire Railway standing on the bridge, giving a total of 750 tons. The date is said to be 1893, but I wonder if it might be a bit earlier. The site of Irlam Locks is in the distance and the old railway bridge just after the viaduct that will replace it. The River Mersey is running in on the right side of the image. The viaduct is still in use today but has been completely rebuilt with new steelwork and extra support pillars for the outside spans.
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.
1/15 sec
f/4
ISO-3200
Noise reduction in Camera is set to Standard. No post processing is done to the photo.
You may find a 100% cropped photo below.
Enjoy
