Shot with Nikon D200, Nikkor NC 35mm f1.4 AI converted. ETTR Method in UniWB, pulled in Lightroom.
Nikon HM3 Lens hood to reduce incidental snow glare. 3 filters in-line to narrow the histogram band into the right region.
This was using:
•CC30M on top, to push the red and blue photosites to match the native green.
•Tiffen circular polarizer in the middle to pull the skies down and further narrow the value band
•Tiffen Ultra Contrast 3 below the polarizer, (closest to the lens), to drastically narrow global contrast and push the majority of the tonal data into the right half of the histogram.
Single exposure, No HDR.
OK no strobes but it's a DIY softbox

AND I took the shot with my p&s in P mode
A range of notebooks with blank, lined, squared and graph pages. Print them on different paper stocks and colours for different effects.
An experiment in coupled "reaction-diffusion systems" (actually, using a mexican hat convolution more akin to field models of neural activity in the cortex). There are two variables with sigmoidal transfer functions, and an adaptation variable that causes the pattern to shift.
messing around with some reaction diffusion patterns for cast ceramics
pattern generation for this piece is the same as this video but larger
Here is my homemade lighting. A 10" clamp-on reflector dish, you know the the ones that are at every hardware store. Clamped onto an extra tripod. Bulb is a fluorescent. Just white, near sunlight. Think there are better bulbs. Diffuser is made out of a 12" embroidery loop wth "rip-stop" white nylon. Note the sticks(Skewer) to take up tension.
Diffusion was a month long festival of photography that ran all May in Cardiff.
Alas, I only managed one event/exhibition and these were taken there, the main exhibition and the Council's old tram shed in Grangetown.
Hope the event is repeated next year
I've just completed a detailed blog post outlining how I diffuse flash on both an MT-24EX twin flashlight and also on a regular flashgun such as a Canon Speedlite. The blog post is here.
Made with Cinder and the Kinect CinderBlock.
Runs in realtime. Playing around with some reaction diffusion.
