In this recurring column, we highlight a few items we've run across that don't merit a full story of their own but are interesting enough to bring to your attention. This time we look at the Milky Way, Sigma's Contemporary 30mm, Stable Diffusion's compression, SF Camerawork and a watch.
- Tim Hardwick presents a few Photos of the Milky Way Were Taken on an iPhone 14 Pro by MacRumors forum member ToddH. "Taken at ISO 12,500 and ISO 10,000 using the 12-megapixel setting (Night Mode isn't available when the 48-Mp setting is on), the images were shot using Apple's ProRaw format and then edited using the mobile version of Lightroom on the iPhone itself," he writes. "To get the shot, ToddH says he attached the iPhone 14 Pro Max to a tripod with a Skywatcher tracking device that moves in the opposite direction of the Earth's rotation, making the sky appear still to the camera to avoid elongation and make the stars look pinpoint."
- Kirk Tuck presents a slide show of images taken with a Sigma Contemporary 30mm f1.4 Lens on a Leica CL. "It was on sale," he says of the lens. "I'll keep it."
- Matthias Bühlmann tested Stable Diffusion Based Image Compression. "As you can see, while Stable Diffusion as codec is a lot better at preserving qualitative aspects of the image down to camera grain (something that most traditional compression algorithms struggle with), the content is still affected by compression artifacts and as such fine features such as the shape of buildings may change," he writes.
- Max Blue reports SF Camerawork Moves to Fort Mason. The local nonprofit has sponsored workshops, lectures and exhibitions since 1974. "The plan, moving forward, is to maintain a hybrid online and in-person model, as Camerawork welcomes the public into its new brick-and-mortar home," he writes.
- The Watch Now tells the time right now. Look, no hands, Mom. It's always "now." (Perhaps also a shutter speed option on future smartphone cameras that rely on computational photography.)
More to come! Meanwhile, here's a look back. And please support our efforts...
