STROBIST: 430ex with stofen diffuser high at camera left on a lightstand (90 deg to camera, even with subject) 420EX behind camera right at waist hight, both triggered by Canon ST-E2 trigger.
A diffuser hack for a Omnibounce/Lambency type of lighting.
The PE-HD bottle it was made from once held lactose. It was left over from one of the kids' medical treatments. If you know what lactose is used for then you'll understand why it's appropriate that it now spills light.
The SB-600 has its 14mm wide adapter folded out and is set for 1/8th power. Capture was 2 seconds at ISO 100, f5. The flash was the only light source.
I still have to check the setup for any colour cast.
A quick test shows that it will cast about the same amount of light on a subject as a flash bounced off the ceiling (for the same flash output and similar distances for flash-subject-ceiling-flash).
A subset of pyranometers used in the diffuse irradiance study collect data from the roof of the SGP radiometer calibration facility.
Unlike the ARM SGP and TWP sites, which have periods of darkness and daylight each day of the year, the NSA site experiences extended periods of both darkness and daylight. Additionally, due to the harsh conditions present there, the broadband radiometers are equipped with electric heaters inside the ventilators to keep hoarfrost and snow from undue interference with the measurements. This IOP, which took place from 2006 to 2007, provided a long term (1-year) set of measurements needed to investigate and refine the IR loss correction methodology for the ARM NSA data.

March 2009.
Nikkor 60mm, homemade flash diffuser, lightroom.
We had a trip to Prague in January 2015 – for Jayne’s birthday - we don’t buy Christmas or birthday presents, we travel instead. We left snowy England for a very, very dull and grey Czech Republic. Yet again I was on a photographic downer looking at the weather forecast, grey is the colour that haunts me. Fortunately it was dull grey and not burnt highlight inducing bright grey.With the grey sky acting like a big diffuser I was going to have deep shadow and contrast to deal with. We had three very short spells of broken cloud which gave us a bit of sun and colour, which I managed to more or less anticipate so we managed to be in decent locations every time – generally somewhere high.
We had been upgraded to a five star hotel, apparently our original choice was flooded. We got compensation and five star hotel upgrade– a first for me. The Art Nouveau Palace has a beautiful interior, with beautiful rooms, the breakfast room was fantastic, as was the breakfast it has to be said. We were able to have an early breakfast so were out on foot just after eight. It was very cold – and dull! We spent the whole week well wrapped up. It drizzled for a day, but never really wet us, it snowed for a day, again we didn’t get wet and the snow didn’t settle. We walked 65 mile, spending plenty of time checking buildings and their interiors out – and coffee shop and bar interiors it has to be said. Although it was dull and sometimes wet I decided that the Camera was staying in my hands for the whole trip. Whenever I put it in my backpack for one reason or another I regret it.
Again, I didn’t look at any photographs of Prague before we got there, I like to just walk and discover, with the DK guidebook in my pocket (which is full of photos it has to be said). We like to get off the beaten track and see the grittier side of the places we visit – within reason! Prague has an incredible tram network, over 1000 trams – with many of them Tatra Eastern Bloc machines. The system seems chaotic but in reality it is incredible with one of the largest networks and highest usages in the world. The trams and cars frequently share the same road space with very little in the way of drama, none of the inexplicable and pathetic constant horn blowing one finds in many countries. Once it became apparent that buildings with a grey blanket as a background were going to be a bit un-inspirational I decided that the trams would be a good focal point instead. Where I have photographed one of the older trams against a background without clues it is easy to imagine that the photos were taken fifty years ago.
The train network also provided photo opportunities. The rolling stock ranges from old Eastern Bloc to very modern double decker’s and pendolinos. There are three stations although we visited the main station and Smichov. The main station interior is art deco and has been renovated by a private company. The exterior and the platforms are very rundown with a grim eastern bloc 1950’s feel –but it works! We discovered to our amusement that we could just walk across multiple lines, no health and safety, just keep your eyes open and don’t walk under a train – you’ll make a mess. Smichov station was grim, it didn’t help that it snowed all day and was grey and bitter. We felt like we were in a 50’s film set in Russia, broken concrete platforms and dereliction. With both stations there was another world underneath them. The underground Metro is running seamlessly and efficiently away beneath your feet. I didn’t have any problems taking photos anywhere but I was very open and obviously a tourist, I didn’t act covertly or suspiciously. There was only one occasion I was stopped and that was in a shopping centre – full of CCTV cameras filming everyone else!
We discovered old and beautiful- and very large- shopping centres hidden away in quite a few places. Brass framed windows and doors, shops thriving, there was a massive camera shop with thousands of second hand cameras, too much to look at. Many of the landmark buildings prevent photography, some make a small charge, some encourage it, the DK guide book gives a good indication regarding camera use. Nothing stops many people though, they just shoot away regardless, usually wanting a picture that includes their self. Prague is surrounded by low hills and has a fair few towers that you can pay a few pounds to go up, so viewpoints are plentiful. I think we visited most of them. I read about the Zizkov Tower, which looks like a Soviet rocket on the horizon and we headed straight for it - after crossing the rail lines! Set in a quiet residential area, there wasn’t a soul about. Two beautiful girls on reception and we parted with a few pounds, into the lift and were on the observation deck with no one else up there. There are fantastic views over the city, but! It is through two layers of not very clean glass so you go for the view rather than sharp panoramas. Still a fascinating place, with a nice café bar and very clean toilets – there are toilets everywhere, usually manned with a fee. Places are well staffed compared with home were three students are supposed to run a 20 screen multiplex cinema.
Graffiti was prominent, no matter how grand the monument, some moron would have daubed it. How do they get away with it in a 24 hour city centre with a strong police presence? The place is very clean, constantly being swept. What did surprise me, was that many buildings, that looked grand and built of stone, from a distance, were actually rendered with very low quality brickwork concealed. When restored the building look very impressive, others are missing the outer render from ground level to a fair height.
I need to cut this short really, I like to put a background story to the photos and although it would be better to individualise it to a specific photo or group of photos I don’t have the time to do that. I do try to give specific detail in the title bar after I have uploaded, this is time consuming enough although I’m pretty proficient at it by now. There are many things I would like to write that should be of interest to anyone thinking of going to Prague but I’ll have to let the pictures do the talking. As usual I am unlikely to be selective enough with my uploads, I’m not very good at leaving photos out so I just upload and be damned.
Edit 21 Oct 2009: I am no longer using this diffuser.
It's a Sto-Fen and I've covered the outside in gaffers tape (to keep light from leaking out if it) and I cut out the front end plastic and replaced it with some diffuser plastic from Bogen.

Den lave vintersolen ble ekstra svak fordi vinden bragte med seg mange små iskrystaller som dempet lyset og solens intensitet.
A simple method of flash diffusion costing pennies. Set the flash head at 45 or 60 degrees and the white card can be bent to any angle you like to soften the harsh flashlight. Use this in addition to other light sources (e.g. daylight from window or outdoors) and set the speed and aperture for the available light and the flash will then fill in the shadows.
The central idea of this is the concave front end. the idea is to match the radius of it to your likely working distance, which should give an even illumination of the subject (assuming you can evenly distribute light across the front screen). There is a 'splitter' inside the housing which deflects light out to the edges of it. This is NOT my idea - several people have similar designs floating in cyberspace (eg search 'Macromeds'). I also must say that I have not cracked the problem of blown highlights yet, so more work to be done there.
Using a diffuser in a wood in North Yorkshire in the autumn and the next image will show it without the diffuser...
The trumpeted exhaust diffuser on the 3000-series buses helps to cool the exhaust gases. (Interesting fact: without the diffuser, the gases are so hot they could set something in their surroundings on fire.) To learn more about the new buses visit trimet.org/newbuses.
I was playing around with using different materials to diffuse the light from a flash light and ended up using a Kleenex to satisfactory results.
The ocean breeze was blowing when I took this shot, so it's not quite as crisp as it should be. I decided to run up to the Reagan Library because they have some pretty gardens there. And a lot of other great things! On a clear day you can see the ocean from there, too :-)))

Float over this picture with your mouse pointer to see my notes. The light does clearly change. Sorry both photos have their own inherent problems (focus & noise) but that's the joy of self-timer shots ;-)
The diffuser I'm using is a Gary Fong Lightsphere Cloud C4. This is attached to my Canon Speedlite 580EX. store.garyfonginc.com/licl.html for info or buy at amazon.com
