Diffuse - The Dictionary of Image.
I am really pleased with how this has turned out. I took this image in a quiet moment at work. I was mixing up some agar mixed with indicator fluid, for an experiment with various molarities of acids. I noticed that the indicator fluid turned the nutrient agar mixture this bright green (acid then turns it pink) and thought it looked really interesting. Then I shook the McCartney bottles up to mix them, before autoclaving them, and thought this then looked even better.
The idea to add the definition of diffuse came to me in a sudden flash of inspiration, when I saw one of my contacts Dictionary of Image submissions, defining 'separation'. I just thought that this worked alongside it nicely.
The text was added with the Gimp, and the font is Andalus.
The definition is from the on-line dictionary service, dictionary.com.

The female Evarcha species on a flash diffuser.
This female Jumping Spider, an Evarcha species, was found in a similar place to the male Evarcha falcata. However, looking it up later it didn't seem be consistent with a female Evarcha falcata, but more like E.arcuata. Although there is one feature missing, and that is the dark cardiac stripe. It looks like a not completely mature specimen.
Any second opinions on the species are welcome as E.arcuata has not been found on this site/area before. I'll be searching for another individual now to confirm the species.
My dad purchased this for me, since I don't have a flash and have to use the onboard one when it's too dark and I'm taking pictures of kids. (They don't like to sit still.) Before he got this for me I was using a piece of wax paper over the flash. Believe it or not, this works better.

I'm working on an assignment to emulate the work of Jay Maisel. One of the things that inspires me about Jay Maisel is his ability to see and produce beauty from the mundane. Instead of copying his photos, I want to see if I could come up with my own mundane beauty. I also love his use of color and hope to go on a color search over the next couple of days! Here I love the diffused light that just kisses the window frame, and the texture created by the sloppy paint job and cobwebs.
Shots taken at 1:1 with my 5Dmk2/MPE-65/430 Ex flash setup.
Top no diffuser
middle my standard coke can diffuser with 1 layer of LCD diffuser + 1 layer kitchen towel. This gives 2 stops light loss compared to no diffuser.
Bottom as the middle but with a layer of LCD dispersion film directly on the flash head. This film gives a 0.2 stops light loss but does give slight but noticeable reduction in contrast. The film when used the right way round has the interesting property of splitting a single light beam into two separate beams.
I obtained both the LCD diffuser and dispersion films from an old portable PC LCD screen I took apart.

Two DIY flash modifiers I made today. One is a simple mini-softbox similar to a previous design. It differs in that it's made from foam core and uses white cloth as it diffusing material.
The other is a new design.
Alcohol bottles are a commonly used to create DIY diffusers. But this one is a little different.
It's a large sized round (cylinder) bottle made with the same translucent white plastic making it ideal softening/diffusing material.
I built this as though it were a mini-softbox, but with a round opening allowing for the severed bottle to fit snugly.
The "softbox" protrudes about 2.5 from the flash, and the bottle about 2 inches with a 4 inch diameter.
It's sized to fit to a Vivitar 285HV flash, and is held on using Velcro straps.
Materials used:
-empty large alcohol bottle
-black foam core
-black gaffers take
-velcro
-epoxy
-white clothe
-white paint
Tools used:
-matte knife
-ruler
-pencil
-cutting mat
-stapler
-Leatherman multi-tool
-paint brush

Series of uncropped shots taken at 2:1 and focus stacked of a fairly high contrast situation of a dark dead fly on a light background.
I was using styrofoam packing sheet for the diffusion where 3 -layers gives a 1 stop light loss from the flash gun.
The non diffused shot actually had a deeper focus stack so the rear of the abdomen is more in focus.
This photo is diffuse because we know that there is light in this picture but we dont know where it is coming from.

These babies are approx 1mm in length. Found them on my wife's roses just under the new growth.
We had a trip to Prague in January – 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.
