I’m super interested in the process that Ethan Moses shows here in this video to make ‘instant’ color ULF photos. Here instant really means direct positive color process, and not anything as easy as a peel apart film. He’s built a film holder that can double as a developing tray so that he can pour the chemicals straight into it after exposing the film. It looks like a lot of fun and the results are quite amazing. He alsoRead more

A Just Noticeable Color Difference
For a long time I’ve wondered what kind of image test could reveal a camera system’s ability to accurately capture color tonality and separation. Grapes, peaches, apples, leaves on a tree, skin and all kinds of things really aren’t just one color but a whole range and often speckled with lot’s of small bits of color. Some sensor’s like the fat pixel Kodak pro MFDB sensors do a great job with this when shot at base ISO but a lotRead more
Lippmann Colour Photography – AlternativePhotography.com
Source: Lippmann Colour Photography – AlternativePhotography.com TL/DR – 1) Interesting technical discussion of one of the earliest color photography methods and 2) a great website that covers alternative photography. Mr. Lippmann won a nobel prize for developing a color photography technique in 1908. He used a interference of light technique where light coming into the glass plate film was also bounced off a mirror behind the plate and thus the image recorded was the resulting combination of incoming light andRead more
DIY Photo Project: Create beautiful abstract photos with polarized crystals – YouTube
I saw this video on making colorful images of crystals by using a cross polarizing technique and thought I’d save it for reference. But the principle is very simple – use two polarizing filters – one on either side of the subject. Maybe you could actually use anything that has a very small change in thickness that light can pass through – plastic sheet that you heat and press patterns into, whatever. DP review TV produced the video.Read more
Filmomat: A really cool film processor that handles 35mm up to 5x7in sheet film!
I’ve been following (lusting after?) the Filmomat since it was first introduced, and at that time the creator had just made it for himself. Now sometime later he’s made it available for sale (although it’s kind of pricy) and that is really exciting. What makes it so cool? First off, it’s really difficult to develop color film at home – the chemicals aren’t expensive or dangerous but color film processing just requires really steady temperature control and at higher temperaturesRead more
Pixar in a box Tutorials on Kahn Academy
I spent part of the day reviewing color science and other really excellent tutorials put together by Pixar staff for the Khan Academy. These were really well done and even though I know color science fairly well, I still felt that there were one or two things to pick up. Perhaps this is because these tutorials are taught from the perspective of making movies which involve of course the science behind it, but also desired emotive effects as well asRead more
