AuRA Rotary Assist Film Developing Machine by Viktor Falendysh — Kickstarter

Here’s a rotary film processing assistant on kickstarter that looks very well made.   I’m curious about how much difference in processing times a rotary drum makes, and whether drum speed, reversal matter.   I see that the AuRA’s standard processing turns fast for 30 seconds then slows down.  Is this really the equal of agitation?   Should a vane or other protrusion be put in the drum to assist with mixing?   I’m guessing that the film reels will provide enough opportunity forRead more

LEARN OPENCV in 3 HOURS with Python | Including 3xProjects | Computer Vision – YouTube

I’ve gone down the rabbit hole for Machine Learning, Computer Vision and have been scanning the internet for different resources.   This is a relatively long video introduction to Open CV, but interesting so I’m posting here.   I’m going to be diving into OpenMV,  OpenVino,  TensorFlow, and more.    I’m particularly fascinated by the AI technology that lets even simple cameras recognize faces, objects, read text, read emotions, recognize gestures,  and more, but at the same time a bit frightened byRead 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

Chromostereopsis – Wikipedia

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

Rolleiflex 6000 – A Passionate Review – By Volker Muth

I’ve met Volker in Germany once during Photokina and he’s a nice guy.  It’s great to see his article on the Rolleiflex 6000 system which is very detailed, but omits a few things about lenses he hasn’t used.    The 90mm APO macro lens by Schneider, the 180/2.8 Schneider, and the 60mm Schneider Curtagon are all missing from his report and personally I think these lenses are some of the jewels of that system.  If he liked the 150mm SonnarRead more

Opinion: Do we really need all those buttons and dials?

Here’s an interesting opinion piece that I first saw on DPR that made me think for a while both about the use of AI in devices and also about ergonomics.  Cell phones are able to make truly remarkable images but the real frustration is that it takes so long to get your camera app open and to take the shot, and when you want to make slight adjustments it’s not all that easy to do so. So while modern camerasRead more

Master Profiles: Bruce Gilden

Portraits taken by Bruce Gilden keep popping up in my Insta feed and I went searching to see what kind of light he was using since I could not always see the catchlight in his subjects eyes.  Now I know why – he uses the flash off camera and sort of jumps out at his subjects and raises the flash with one hand while shooting with the camera held lower in his other hand.  This technique seems to work reallyRead more
