This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
Uranyl nitrate was combined with NaCl and recrystallized on the glass rod. Behind it is a specimen of meta-autunite from the Daybreak Mine in Spokane WA, USA. Meta-autunite is a uranyl phosphate mineral.
Uranyl nitrate solution (0.25M) was combined with a sodium carbonate solution (1.25M) and was used to rehydrate some DAP Plaster of Paris mix which was set in a square mold.
Initially (when still wet), there was no fluorescence but after the calcium sulfate re-hydrated (and the mix produced CO2? bubbles), the resulting plaster fluoresced a bright blue-green, typical of carbonate based uranyl minerals. Behind the plaster square is a specimen with a coating of andersonite from Yellow Cat Mesa in Grant County UT, USA. Andersonite is a hydrated sodium calcium uranyl carbonate.

Much appreciation to Gordon Czop for the uranyl nitrate.

By doing this capillary flow experiment in space we discovered several surprising mechanisms of fluid behaviour. Important for 1000s of industrial processes.

Experimenting with some new toys the other day. I hope to have some subjects other than myself to shoot pretty soon.. I'll let you know!
Another shot from the set I shot with my photography student, Lucy, at Meiji-jingu Shrine last week. The shot on the left was made using my Micro-Nikkor 105mm f/2.8 AF D lens and the one on the right with a Nikkor Ai 50mm f/1.2. Lucy and I spent an hour shooting this subject, exploring all the angles, experimenting with the exposures and moods we could create by varying them. Great fun. I, for one, was beginning to get a truly 'zen' oneness with the object by the time we finished.

Post-processing in Photoshop using Nik Colour Suite 3's cross-processing, darken/lighten centre and Alien Skin's Coliur Film emulation plugin.
All filters faded back, blended, overlayed etc etc. The right-hand shot als had an adjustment layer [hue/saturation] applied, with sections erased and faded.
A photoshoot with model Myrthe,
I experimented with my diy beautydish and the post processing in photoshop.
Light setup:
metz 45 with diy beautydish above the model as main light.
metz 45 camera left behind the model.
metz 45 camera mounted with a umbrella right at eye level as a fill.
Here are a few shots from an experiment my friend and I did about a year ago. The idea was to drop the dice from about 1.5 feet and get them in focus as they bounced. I think we did ok.

Connectivity and readymade.
Experimenting, manipulating and combining daily life objects in order to attempt, to force or to mystify a workable connection between them, at least to make it visible and/or possible. This exercise is to be considered as a warm-up, a first step towards a further installation or project.

For me, fashion is a form of art. I wanted to take the time and experiment with some styles and colors to se what works and what doesn’t. Feel free to comment on what styles you think work best 😃
Transmitted light.
Paper: Ruscombe Chateau Vellum 85g, 4x5".
Process: dry exposed calotype instr. Pelegry
Iodised in Pelegry iodizer with no whey but extra lactose
Exposed June 18th, 2012 ca 14.00, indirect indoor light, on a sunny day with veiled skies
Exposure time: 10 min f/8
Developed 50 mins, 0,8% gallic acid 300 ml, a shot of 2 ml AgNo3 added after 20 min
The thin Chateau Vellum is beautiful paper, but it does have a rather coarse structure in transmitted light… Might get a bit better when waxing, but that will be for a later stage…
This is the last sheet of my brushed Pelegry batch. Brushing works, but you are looking for trouble. Some overcast days might be coming up, so I might try and print one of these early experiments…

ESA astronaut Luca Parmitano waves from the bus that will transport him and his crewmates from the Cosmonaut Hotel to Baikonur cosmodrome in Kazakhstan.
Luca, NASA astronaut Drew Morgan and Roscosmos cosmonaut and Soyuz commander Alexander Skvortsov will be launched in their Soyuz MS-13 spacecraft from the Baikonur Cosmodrome on Saturday 20 July. This date coincides with the 50th anniversary of the Apollo 11 Moon landing and marks the start of Luca’s second space mission known as ‘Beyond’.
While in orbit, Luca will support over 50 European experiments and more than 200 international experiments. He is also expected to perform a number of spacewalks to repair the cooling systems of dark matter hunter, AMS-02.
More information about Luca’s Beyond mission is available on the blog. This will be updated throughout his mission, with updates also shared on Twitter via @esaspaceflight.

This started out as an experiment in stacking focus but I gave up and took only 1 shot. The experiment will be attempted again in the near future.
