The X3 sensor records full RGB colour at every photocell site on the sensor, thanks to three photocells embedded at different depths in a silicon wafer. Sigma now owns the Foveon company, and has continued to use this innovative technology in its cameras, including the DP2s compact camera which I reviewed back in June, as well as Sigma’s most recent DSLR the SD15.The Foveon X3 sensor works in a different way to the standard CCD and CMOS sensors found in every other digital camera.Ĭonventional camera sensors only record brightness, relying on a red, green and blue mosaic filter to provide colour information, and interpolating the full colour image from the results. The challenge for me now isn't to take good pictures, its to produce emotive pictures which no self-respecting camera has a right to take.I’ve been following the development of the unique Foveon X3 sensor since its first appearance in the Sigma SD9 back in 2002. The kit nowadays is too good, even my 4 year old can take some cracking pictures, which means there isn't any challenge anymore: no spending hours in a darkroom snorting dodgy chemicals no humping half a ton of mechanical wonder camera kit up a hill. It's taken a little over a year to figure this out. So, I've finally found utopia, so why did I loose the inspiration to take pictures? Prints are exceptional (ridiculously good), usage is a breeze: just point and shoot, and it rarely lets me down. Last year I traded again for a mirrorless setup. ![]() My old film kit looked good, felt good, but was a pain in the bum to use and rarely did I get an exceptional print from it.Ī few years back I traded the lot, darkroom included, for a DSLR setup. Not because I'm stuck in my ways, but because I spend all day on a computer, so didn't want to spend all night on one too. Ok, for years I resisted the digital revolution. Reduce saturation to -50'ish (depending on the intensity of the hotspot). open the image in Macphun's Intensify applicationĤ). (this is a slight cludge, but works for most imagesġ). Here you will now have a full false-colour-processed IR image. Go to Colors > Components > Channel Mixer OK, first step: get the red picture off your Digital Camera and then:Ģ). (if you haven't tried Macphun's applications you're missing something quite special.) Macphun's Tonality, Intensify Pro and Snapheal. My other plugins are paid-for items, but worth every penny: Absolutely essential to the process is "The GIMP" - the open source photoshop alternative. So, I've long been an Apple Aperture user, and with the help of some plug-ins, have a pretty stable IR workflow. The price is annoying, but the new subscription model is a stopping point: I reserve the right not to be connected to the Internet. I'm no doubt shooting myself in both feet, but I have an aversion to Photoshop. Skin reflectance 600-650nm (red) abs 580 (yellow) better results achieved by running colour map through crazy bump first! if available, link variable sss to alpha colour outputġ4. highlight intensity to 10%, global to 10%ġ1. set highlight colour to 75% of main colourĦ. click force extension, set to 0.2 (or higher - depends on skull showing through)ĥ. link bump to alpha map (connected to transparency)Ĥ. ![]() Load picture, include transparency, link bump to pictureĥ. if available, select variable depth and link map to colour outputġ. if looking too golden, then adjust scattering colour based on the formula:Ģ0. ![]() absorption filter colour copy from color tabġ9.

NOTE: I think this can be bettered using a 3layer Donner/Jenson model, but haven't achieved it yet.Ĥ. When importing MakeHuman (collada) model into Vue, here is the basic render setup.
