I’ve been experimenting with colour infrared video and photography for some time, photography is easier due to the IR blocking filter on my stills camera being quite weak, plus manipulating RAW images in Photoshop and Gimp using colour channel swapping is very effective. However video is another matter entirely, the IR blocking filter on my Canon HV40 is quite strong so filming on very bright sunny days is essential, then manipulating the imagery in After Effects can be long and unpredictable, film grain/noise needs to be removed, channel swapping in video is not very clean so many more effects are needed to produce a ‘respectable’ clip.
I’ve put some IR video clips together in this edit to give you an idea of what can be achieved.
Here is a November desktop wallpaper for you, it was shot at the Lea Valley river in East London using a Nikon D70 and a Hoya IR filter.

Some time ago I was shown this video of ‘circles dancing in a rhomb’ by
At the time it inspired me to create some interesting patterns with crochet, based around the negative space within the structures and the rhythmic dance of the circles within the shape.
But it was the cellular structure of plants that the video reminded me of most, cross sections of plant stems show similar patterning due to the negative spaces created by the vascular bundles, cork, cambium and pith.
The video below is a rough edit of a sort of conversation between Gelada’s computational realisation and forms found in nature and captured on my new microscope :)
I unexpectedly got a Bresser Biolux NV microscope with USB camera for xmas, it’s a good hobbyist microscope with 4x, 10x and 40x objectives, the kit came with some prepared specimens and even some shrimp eggs and an incubator for growing them, as well as spare slides and cover slips
Here are some captures from the included slides :
And here is a video capture that has been processed as b&w and inverted
I’ve been doing lots of online After Effects tutorials recently as I’d like to add cgi effects to some of the footage I shot over the summer with an aim to represent natural phenomena such at photosynthesis and gravitation.
Things are going well and I’m getting my head around the use of fractal noise, particles and using lights to project images onto surface meshes.
I’m particularly proud of my Earth which was created entirely in After effects using CC-Sphere and fractal noise as well as jpeg maps.
You can find lots of cool AE tutorials here and here
The biology of cells has always fascinated me, I follow a few flickr groups on the subject and have been very impressed by the work of Tatcher a Hainu
Flower stalk of a dalia by Tatcher a Hainu
I like the way he stains his specimens and and the level of detail in his photography.
However it is Darkfield microscopy that really inspires me due to the high contrast levels and black backgrounds which make it suitable for projection and video mixing.
Here is a superb example of micro-videography, a capture of the algae Volvox…
Volvox aureus, darkfield moves by Jens Hallfeldt
From what I can gather he used a professional microscope, the Olympus CH40, a very nice DSLR, the Canon 5dII and a Zeiss Ultracondenser.
I attended a workshop that set out to explore the relationship between flickering lights and perception using DIY circuit boards and LEDs. We soldered components to a board and added controllers, speaker connections and LEDs to create experimental ‘hypnosis’ goggles.
This was my second attempt at soldering, the first was when I tried to fix my television with a soldering kit from Argos. I found the soldering quite tricky to begin with and constantly dripped solder over several copper covered columns on the boards but luckily the workshop organiser Ryan Jordan was very helpful and patient. We connected the 555 chip enabled circuit boards to safety goggles and then hallucinated away, here is a video
I however did not finish my goggles and filmed the event instead :) but the circuitry proved useful during my bike ride home when I attached it to my bike as a flashing front light, it also made another appearance later in the evening during an improptu light show at Electrovision…
In September I was looking forward to capturing the Harvest moon in timelapse, this is the first full moon closest to the autumnal equinox and is unique in that it appears early in the evening, and very low on the horizon. This creates an optical illlusion whereby we percieve the moon to be much bigger than it actually is.
I had purchased an intevalometer from GentLED and attached it to my Nikon D70 then set up my tripod in the back garden with the camera pointing towards the skys.
Here is the result
However I was a day late and could only film after getting home late in the evening, so this is not in fact the harvest moon :( nevermind, I will try again next year…
