fsorvin Autochrome LUT

Autochromes were not commonly printed (unless transferred for mass printing, like in National Geographic), but were more commonly viewed in a stereoscope or with a diascope, a box that used daylight, a mirror and a diffusion plate to illuminate the camera original plate from behind.

Autochrome’s mosaic, dyed potato starch grains of red-orange, green and blue-violet, were so small as to be invisible but blended together to form the impression of colour, much like an RGB display does now. Visible were the clumps formed by the imprecise spread of grains on the colour mosaic. This LUT cannot simulate the clumping. If you want to simulatate it, add in a noise layer before the LUT in your image chain. The orange-red, green and violet-blue can produce some seriously beautiful skin tones, as well as some interesting landscapes. Dial up the vividness or saturation for the colour of dreams, or dial it all back for a vintage faded look, if that’s your thing. And if it’s really your thing to be authentic, shoot with long exposure times. Autochrome had exposures of 3 to 4 seconds in daylight, so get your subjects to pose and bring your tripod. Autochromes tended to be blue shifted, so Lumiere recommended a yellow filter be used in front of the lens. Included in this LUT pack is a set of pre-filtered LUTs, set from 10% to 40% yellow, as well as an unfiltered LUT that you can dial in your own yellow filter. Just use a Yellow solid layer at Hue: 59, Brightness 100% and play with Saturation from 0 to 100%. Multiply the layer over your original and you should be good to go. This and my other LUTs can be though of as colour transformation processes. They aren’t designed with specific cameras in mind, or to transform log-encoded footage. They digitally apply the colour transform process that colour and density would go through in a Autochrome process. Apply the LUTs using your favourite LUT utility. Comes as a 3D 32-bit LUT, so it works in all LUT situations like Premiere, After Effects, Photoshop, monitors and even iPhone/Android apps. Gumroad requires an email address.
