Pictured are RAF recruits during their fitness test at the end of basic training...Sport develops both confidence and improves fitness whilst creating the opportunity to have a sense of belonging and make friends; all of which resound during Basic Recruit Training...The RAF is an agile force that demands high levels of physical robustness and readiness, fitness is heavily encouraged in the RAF.
Recruits will be expected to meet the RAF standard of fitness so that Physical Education Flight (PEd) can build on this to teach you to work effectively in tiring and stressful situations.
Fitness testing begins early in the selection process with the Pre-Joining Fitness Test (PJFT) and is regularly assessed with the RAF Fitness Test (RAFFT) which you will take on your Pre-Recruit Training Course (PRTC).

Exposure and development test to get a suitable negative for cyanotype printing providing detailed shadows and highlights
.
Ilford HP5+ exposed at 50 iso, 4 sec. at f/16
5 mins at 20°C in HC-110 dilution H 1+63
Cyanotype contact print exposed 25 mins in my UV box
4x5 Arca F-line, Rodenstock Sironar N 150 mm
test shot with the Sigma 85mm F1.4 on my Sony a7RII (ILCE-7RM2) using the LA EA3 A-to-E adapter, only thing I did in post processing was to noise reduction
shot with compressed RAW
I've bought myself some new toys and this is my first try using Nikkor 50mm F/1.8 AF-S lens and the Bokeh Masters Kit.
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.

This is a test of the exposure range of Fuji Neopan 400 developed in D76 1+1. It ranges from -6 to +8.
The range of exposure is dictated by the shutter speeds of my Canon A1. 30s to 1/1000 and by results. There is still a usable albeit very washed out image at +8. However when it comes to under exposure the film fairs less well, with no visible image at -7.
This is in comparison to a similar test conducted on Kodak Tmax 400 also developed in D76 1+1 here www.flickr.com/groups/ishootfilm/discuss/72157632397197365/
apologies for the bad alignments of shots, but then this is for shits and giggles rather than serious science.

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.

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).
I built this for the guys over at tested.com, as a thank you for having me as a guest on Octobercast 2013.
Testing the New 7D Mark II

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

DERBY, ENGLAND - MAY 18: UltraFan® on Test Event on Testbed 80, Wilmore Road, Derby. Testbed 80 is the world's largest and smartest indoor aero engine testbed. The UltraFan® is 25% more efficient than the first-generation Trent and offers 40% less NOx and 35% less noise and almost zero nvPM particulates at cruise.
Did some High ISO test today. Results are pretty impressive. Here are the Exif data.

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.

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!)

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.
