Looking at Bokeh

How to characterize the styles and traits of different lenses Many lenses draw with different characteristics and often have family/brand traits, but it’s sometimes hard to see those differences. Often times the only way to see them is to look at the out of focus rendering. This article will be mostly a place for me to put some images into the same spot and to hold my notes, but I’d love to hear from others who have studied this inRead more

Kodak Tri-X vs. Ilford HP5 – A photo comparison by The Darkroom Photo Lab

I thought this was a very useful film stock comparison and wanted to post it both for other and also so I can come back to it.   Personally I mostly shoot T-Max 400 and Ilford Delta 3200, but now that I’m shooting 8×10 and 11×14 I’ve started to shoot a lot more Ilford film stocks since they are available and less expensive.  What film stocks do you like? WHAT DO YOU LIKE? Kodak Tri-X 400 classic grain structure, contrast, deep blacksRead more

European Month of Photography

European Month of Photography EMOP or European Month of Photography: That is your excuse for your next European vacation – or at least it might be mine!   I was just looking at the web page for the EMOP Berlin – which was held from Oct 1st to 31st in 2020 and realized how cool that would have been to be there.  I always enjoyed the photo exhibitions that coincided with Photokina.   The cities which have EMOP are Athens, Berlin, Paris,Read more

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

Canon hails groundbreaking 1-megapixel SPAD image sensor as the “eye of the future” – DIY Photography

Canon has developed what was everybody thought to be impossible. And while it might not be the highest resolution camera sensor out there, Canon’s new 1-megapixel Single Photon Avalanche Detection (SPAD) sensor offers some huge benefits over more traditional CMOS or CCD sensors. The biggest being that it all but eliminates noise from your images. […] Source: Canon hails groundbreaking 1-megapixel SPAD image sensor as the “eye of the future” – DIY PhotographyRead more
