As seen through my new macro lens, this is the test (calcium carbonate structural shell) of a small sea urchin that was unknown to science until one was purchased on eBay in 2006 and subesqently described by Natural History Museum scientists Simon Coppard and Heinke Schultz. I bought this test on eBay right around that time, unaware of this fact.
::::::::::::::::
Sea urchins are members of the phylum Echinodermata, which also includes sea stars, sea cucumbers, brittle stars, and crinoids. Like other echinoderms they have fivefold symmetry (called pentamerism) and a mouth locatted ventrally. This species is from New Caledonia, and this particular test is about 1.6cm wide.
Alternative Photo a Day -one of the first shots using my new camera and Lightroom upgrade . I had no idea that I'd set the ISO so high lol!
NAWCAD Trenton, located in Mercer County, New Jersey, consists of about 66 acres with a total of 96 buildings and structures. The center was used to test jet engines, alternative fuels, turbines, and engine starters.
The main "hangar" at NAWCAD. Im not exactly sure what this building was used for but there are slots in the ground about a foot deep and there are spikes and stands that stick out of them. It looks like you would brace something on top of them. You can see the slots better in this picture.
A toy? Not really, this lens can really deliver amazingly sharp results!
--- Lessons learned:
+ best way to get the grips is to use the lens with the cam (in liveview) tethered to a tv set via DVI
+ the lens should not be used on maximum tilt -- you cannot get sharp results with this adjustment
+ the two lenses in the Lensbaby are not coated, backlight will lead to overlit blurry results ...
+ This is a 50 mm lens, minimum object distance is approx 0,6 meters ...
+ shots were take with the 4.0 aperture, ... 5.6 has a wider sweet spot, but less wow effect
+ works fine in Av-Mode
--- This is how focusing works:
Point the optical axis of the lens **exactly** towards the spot you want to focus; adjust focus ring - if possible in zoomed liveview mode.
--- This is how it not works:
Leave the lens as-is (no tilting); try to focus on an object in the corner of the image via turning the focusing wheel.
--- One problem I came across:
The 5DMkII works fine with this lens in Av mode, even better with additional liveview, but does *not* adjust exposure in *zoomed* liveview! => Firstly wait for exposure adjustment, then zoom in, adjust focus, if possible, zoom out again, shoot. :-)

There was a really simple device for testing for the level of contamination on your shoes and hands.
Photos here were shot using old Canon FL/FD lenses mounted onto the new compact mirrorless full frame Sony Alpha A7 released on November 13, 2013 in Japan. The lenses are all manual focus due to the fact they are old legacy prime lenses. The Canon lenses used for this test:
FD 35mm, f2
FL 50mm, f1.4
FD 135mm, f3.5
FD 135mm, f3.5 (with PL filter)
This photo was taken using the portrait focal length, FD 135mm, f3.5 lens.

A first look at the Panasonic Lumix G7. Having had the camera for a couple of weeks now, the results I am getting are fantastic. And whilst none of the images in this set (Plenty more to come) are 4K still images the 4K video on the camera is fantastic as are the stills it produces. In the coming week I will be adding a blog post to PhotoOOmph.com to go through my thoughts on the camera. Keep an eye out, and any questions just leave them as a comment and Ill get back to you!
Test of an inexpensive Neewer LED Macro Ring Flash FC100. The subject is about 3cm across and is a tricky one - shiny brass. At this distance the flash works well with a shutter speed of 1/160th, f8, ISO 200 but the flash lacks power. If I move away to a distance of half a metre I can't get a decent shot at ISO 200 even at f2.8, the flash isn't powerful enough. But for the money it's very good for real macro work.
I sent Daisy to the kitchen for some selfie-practice on New Years Day. I think this must be the testing phase. 😉
Tilt test model showing a large scale RT model on the tilting platform. Model is in the LT museum Covent Garden.
Tested these brands and some more. Will need some time to round up the results...
Too many things too do, too little time.

Test Roll of Lomography CN 400 in my new Lomogrpahy Konstruktor DIY SLR.
Overall the pictures are okay. I don't think I'd be using it that often, the 1/80 shutter speed is just a bit too slow unless you stop and stand still.
Also it likes to eat film.
A Bristol Siddeley-Maybach MD655 engine, from a BR Western Region Class 52 diesel-hydraulic locomotive, under stationary test at Swindon Works. Taken on an open day, Saturday 13th September 1975. The engineer in charge ...a white-coated, bespectacled, middle-aged man... sat behind the window of a control room at the top of a flight of steps. From time to time he would notch up a handle on his console to increase the engine revs, which were displayed as flickering red numerals on a screen. In the confined space this produced a most satisfying din.
