HEIC, WebP, AVIF, and JPEG XL measured against the only questions that matter: how much bandwidth they actually save, which features they carry, and the patent and browser-support realities that decide adoption regardless of who compresses best.

Image Codecs Compared -
Modern Video Codecs H.264, HEVC, AV1, and VVC measured on the axes that actually decide a codec's fate: rate-distortion efficiency, hardware decode support, and a patent landscape that has killed technically superior formats outright. A working account of where each one really wins.
-
Strobe vs Continuous Light Strobe and continuous light are not competitors for the same job — they put their energy in different places in time, and that single difference dictates motion-freezing, sync speed, color rendering, heat, and whether you can shoot video at all. A working photographer's honest comparison.
-
The Physical Camera vs The Phone in 2026 The phone won photography on volume and convenience, and for most pictures it is the right tool. The honest question is the narrow set of jobs a dedicated camera still wins — low light, telephoto reach, real optical depth of field, and all-day ergonomics — and why those wins come down to physics computation can mask but not repeal.
-
Tripods, Heads, and Why You Pay A tripod is a stiffness-and-damping machine, not a weight-holder, and that reframes everything about what your money buys. Load ratings are nearly fiction, the head is where most people mis-spend, and weight is a tax you pay for either stability or portability — rarely both.
-
Autofocus Systems Explained Autofocus is the camera feature most photographers stopped thinking about decades ago, and it has been quietly reinvented twice since then. We walk contrast-detect versus phase-detect history, the on-sensor phase-detect revolution that mirrorless made standard, the neural-network subject and eye detection that defines 2026 flagship performance, and the honest gap between marketing claims and what actually focuses in real shoots.
-
Image Stabilization Image stabilization lets you handhold shots that would have been impossible on film, and the engineering behind it sits in the intersection of MEMS gyroscopes, real-time control loops, and clever optomechanics. We walk optical (in-lens) versus sensor-shift (IBIS) stabilization, why the math differs, why some bodies and lenses stabilize so much better, and the honest "stops of stabilization" reality.
-
RAW vs JPEG RAW and JPEG are two answers to the same question — what should the camera write to the card when you press the shutter — and the answers look very different at the bit level. We walk what each file actually contains, the in-camera pipeline that bridges them, why white balance and tone curves are "settings" on JPEG and "metadata" on RAW, and the honest case for each format in different situations.
-
Color Management Across Cameras, Screens, and Prints Color management is the part of imaging that most people quietly resign themselves to never understanding, and the operational reality is much simpler than the documentation makes it sound. We walk color spaces, ICC profiles, the calibration chain, why your monitor and your print do not match, and the honest workflow that produces consistent color across cameras, screens, and prints.
-
Computational Photography A modern phone camera captures one image to display and computes perhaps a dozen behind it, fusing them into a result no single exposure could deliver. We walk what the phone's pipeline actually does between shutter press and saved JPEG: multi-frame alignment, HDR fusion, night-mode stacking, semantic segmentation for portrait mode, and the honest line between optical capture and after-the-fact reconstruction.
-
How a Camera Sensor Works Every photograph starts at a piece of silicon counting photons, and almost every interesting difference between a phone and a full-frame camera traces back to sensor engineering. We walk the photon-to- electron conversion, the Bayer color filter array, back-side illumination, stacked sensors, the ADC and read-noise budget, and why the same scene produces very different files on different chips.
-
Lens Engineering A modern camera lens is a stack of 15 or more shaped pieces of carefully chosen glass, each fighting a specific optical defect, and the engineering behind it is one of the more underappreciated stories in consumer technology. We walk the aberrations every lens has to correct, what aspherics and low-dispersion glass and fluorite actually do, why fast glass is heavy, and the honest case for a $2000 prime over a $400 kit zoom.
