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

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

Did You Know You Can Archive Your Digital Photos on Analog Film? |

For those who diligently perform DAM or are interested – a new worry for you… bit rot.  Nope, not just with files stored on CD or DVD ROM.   This is in addition to the regular updates in terms of long term data storage technology.  I think Dr’s offices are the slowest to adopt new tech – I mean you still have to fax over referrals, and they will give you a copy of your X-ray on CD.  I mean newRead more

Daniel Wolf, 65, Dies; Helped Create a Market for Art Photography

When I was at UC Berkeley studying Physics, I added a BA in fine arts. At that time, I have to confess that didn’t consider photography to be Fine Art and thought of it more as craft.  I had been making some ‘artistic’ photos and printing them in the darkroom, but somehow my mind was locked.  My opinion didn’t change until about 2000 when the very first digital cameras.  This article about Daniel Wolf creating an art market for photographyRead more
