Una punta de una de las estrella acuñadas en una moneda de 1 céntimo de euro. El objetivo es un Scheider Kreuznach 28mm f/4 de ampliadora y está a un aumento de unos 10X montado en fuelle.
Con luz de flash directa los efectos de la difracción son muy visibles, en cada punto brillante se ven los discos de Airy y aparecen moteados de colores por la dispersión de la luz en la superficie del metal.
My first Lego stop motion test. I think it came out quiet well. Constructive criticism is appreciated. Link: www.youtube.com/watch?v=yPgIoIowYoA
Ricoh TLS 401, Fuji Superia 400 (accidentally shot at 200. Oops!), Auto Sears 55/1.4 w/ Camron UV filter. Negatives Scanned.
Test roll through the camera body that apparently has seen no use since 1984. The meter doesn't work, so I used the LightMeter app by David Quiles Amat on my Galaxy Note II.
Disclaimer in regard to focus: WOW this thing's viewfinder is terrible. The waist-level finder is OK, but small. The eye-level finder is practically impossible, plus mine is cracked and filthy inside... Just crossed my fingers and fired the shutter.
Taken with SX-70, wheel darkened one and one-half marks. Taken outdoors with the sun behind a cloud during mid day. Strange how this one only required one and one-half, but my other shade images required three marks.
Work-in-progress renderings of a conjectural model of the topsail schooner Invincible, c. 1836. No plans of the vessel are known to survive, although her hull dimensions are known. This model is based on plans of similar, contemporary craft. The length of the lower masts looks off; I oughter double-check that.
Haven't given the whole realism thing a go before s thought I'd see how it comes out. Not really that big a fan of realism stuff but quite pleased with these.
Done pretty quickly and not too neat but just tests.
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.
Testing Lamy ink for review. This is a test on an index card. See the notes for what the bits are. Next pic in the photostream is more testing - same stuff in a Moleskine, and the PigPog Smudge Test.
The plan is to do this same pattern with a few different inks, as a way of comparing. If anyone's got any ideas on better ways of doing it, I'd love to hear them.
testing out the new bees with a self portrait...
Strobist: AB800 1/8 power camera right thru Softbox

North Shore, BC.
It was cold, you can't see the south side of the lake, but it is still lined with snow banks, with the occasional calving off.
A few last minute low light tests using the Fuji X100s camera. A: Quietly in a dark live theatre show 'Little Mercy' B: a dark sunset catching much of the Western sunset opposite the Harbour Bridge from Walsh Bay wharfs.

There was a really simple device for testing for the level of contamination on your shoes and hands.
This is a test shot of Bridgelux Vero 18 35W LED module, p/n BXRC-30H4000-F-03. This LED is advertised as having CRI 97 and 4000 lm luminous flux, which is equivalent to characteristics of 150W halogen lamp. Color temperature should be about 3000K.
This photo was taken in complete darkness without any optics covering LED module. Paper with pastel swatches was located in about 100mm from the module and set at 45º to its axis. Camera was set to 3200K color temperature and I had to close the diaphragm pretty much to get this paper properly exposed.
As you can see, color balance is a bit off the uniform in reds, but it's normal for high CRI LEDs because of wider "red hump" in their spectrum. At least, it's not worse than "orange hump" of halogens. 3000K seems to be real number too. Swatches are bright and equally lit, which is impossible with regular LEDs, having CRI 72 or even worse, which is equivalent to cheap fluorescent tubes.
To prevent overheating, I've used HP server CPU passive heatsink, p/n 409498-001 (bought used one from eBay for less than $10). It keeps the LED temperature just above the body temperature, so it's a kind of overhead, which I expected - this heatsink is intended for CPUs with TDP more than 65W. It means, I can use smaller cylindrical one with small (40mm) fan.

My new test-setup for lens-testing. Read more about this at Camera Labs
