Anyway, I just read a paper, being published soon, in which that advice was proven useful yet again.

30 years ago, Bob Morris, then a senior scientist at NSA, gave a keynote talk at the CRYPTO conference (the leading conference for academic cryptographers).

He opened by telling us he would reveal the NSA's first rule for cryptanalysis (which certainly got our attention). "First", he said […]

Captured with the Rodenstock 50mm Digaron lens and about 13mm of vertical shift to maintain the geometry (but several architectural features - setbacks and tapers in the building design - still make it appear to converge toward the top).

So this was mostly a play on the concept of "street photography". The street is the literal subject, but everything about it - the absence of people or any depiction of street life, the use of a heavy, tripod-laden camera, the compositional formality - defies the conventions of that genre.

This is a high resolution stitch of three captures with the Rodenstock 32mm/4.0 HR Digaron lens, yielding a 230 MP image with roughly the angle of view of a 14mm "full frame" rectilinear lens. The high resolution invites you to look closely for signs of life, but they remain elusive.

While this […]

@Edent So what? Nothing about having alt text embedded in EXIF data stops from being able to edit it for specific contexts in the rare cases where it needs to be.

I just want it to be easier to make my images accessible. Being able to compose thoughtful descriptions in advance, once, rather […]

Really comprehensive and timely thread (still in progress) by @heidilifeldman on the legal issues with Trump’s federalizing and deploying various state’s National Guards for domestic law enforcement duties in other states.

I finally have finished reading the 69 page complaint and multiple exhibits filed by the state of Illinois and City of Chicago against Trump, Noem, Hegseth etc., seeking to prohibit them deploying federalized National Guard troops in #Chicago. #Chicagoland #LawFedi https://storage.courtlistener.com/recap/gov.uscourts.ilnd.487574/gov.uscourts.ilnd.487574.1.0_4.pdf 1/

I'm not sure why there's all this controversy all of a sudden over things written by people who hold a one-year master's degree in law.

Getting a small swarm of people "reminding" me to use alt text, I guess because I seem like the sort of person who probably doesn't.

The metadata for this image claims it was shot at f/16. That's wrong; it was more like f/2.5 or so. This was an artifact of the too-clever-by-half way Leica M cameras estimate the f stop. There's no mechanical link between the aperture ring and the camera body, so instead they estimate the […]

Captured with a small full-frame camera and 21mm lens. A three second exposure smoothed waves and surf.

This was an exercise in tone, perspective, and convergence. The four major boundaries of the scene converge (approximately) near the center of the frame, forming a flattened X.

I moved […]

Periodic reminder: I post an approximately daily image-of-the-day here, along with a short thread with technical details on the image and/or background about the subject. I generally re-boost it in the (US Eastern) evening, for the night crew.

I should note that none of this is technically difficult. Many image editors can embed and edit arbitrary EXIF fields (GPS location, captions, copyright, exposure, etc). Extracting data from EXIF is straightforward for websites that process images. The software part is easy here, and mostly done […]
