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

Chromostereopsis – I just learned this word for visual illusions that convey an impression of depth.  Artists have taken advantage of this property for eons.  A discussion on dpreview about depth of field in captured images theorized that chromatic aberration from some lenses helped the perception of depth and even that perhaps humans and other animals have evolved to use chromatic aberration to their advantage.   This information was deployed in to suggest that older less perfect camera lenses may actuallyRead 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.
