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.

I didn't have much opportunity to test my newly bought Speedlight flash. So Merlijn had the honours to de-virginize it.
Although he wasn't keen on posing today, I think this image came out pretty well. I am happy with my new toy.

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
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).
Testing the New 7D Mark II
This Bird was far away from me around 150 meter !!!
Sparrowhawk (sometimes sparrow hawk) may refer to several species of small hawk in the genus Accipiter. "Sparrow-hawk" or sparhawk originally referred to Accipiter nisus, now called "Eurasian" or "northern" sparrowhawk to distinguish it from other species.
The American kestrel (Falco sparverius), a North American falcon species, is also commonly referred to as a sparrowhawk
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.
Testing out a DYI camera rotation rig. Just pointing it at the TV in the living room with a TV tray table in the foreground. 8 exposures at 45 degree increments.
A mobile fuel test unit, also called a 'prover' truck, used to test accuracy of gasoline pumps. A certain amount of gasoline is pumped into the small stainless steel tanks and measured on the devise above them.
Testing Oblivion House converted to Skyrim with new textures, now I need to add glow to the windows so shine at night
Trying out still life.
Testing out the Phottix Odin System. Sb910 in wescott 8x 12 softbox left and Yongnuo in wescott 8x12 softbox right ( didn't trigger appropiate flash level as they it's not compatible with the odin system). Generay Video Light on top of lens to creat the glow in the subject lens. I had the mitros + in the rear. Ironically the Nikon Df is on a video tilt head that I will never be used because the Df doesn't do video.
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.

With the wide availability of Covid-19 vaccines in Southern California, this Bus Test Express (Say that three times fast!) had no test-takers Wednesday afternoon while in the parking lot of a busy Montclair shopping center.
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.

37602 is now seen on the rear of 1Q13 test train as it heads for Tondu at Margam in some gorgeous evening light. 9/7/13.
Testing the Ibis 66 for a friend - and I'm sure he will have a lot of fun with her.
There is one item: don't pull out the lens immediately before you make a picture, you could pull a vacuum, and your film could be out of focus.
