Photographing things that change too slowly to notice.
Method, not motivation. Cadence tables, lighting, the maths behind a watchable time-lapse, and what we learn building a camera that holds onto the last photo.

How to photograph body recomposition accurately
When muscle increases and fat decreases, the scale stays completely flat. Here is how to photograph body recomposition with fixed lighting, distance, and posture.
Body recomposition replaces lower-density adipose tissue with higher-density muscle tissue, meaning your total scale weight may not move for months at a time. The only objective proof is visual geometry. To track recomposition accurately: photograph every 14 days under diffuse indirect light, stand 6–8 feet from a navel-height camera, and hold a strictly relaxed neutral posture without flexing.

Why software stabilization cannot fix misaligned progress photos
Software warping and post-capture alignment tools crop your frame, invent artificial pixels, and fail at 3D parallax. Here is why capture-time alignment is the only real fix.

How often should you take progress photos?
A cadence for eleven subjects, from daily selfies to monthly baby photos, and the rule that decides all of them: never shoot faster than the subject changes.

Why your before and after photos do not match
Four variables decide whether two photos months apart can be compared: distance, height, angle and light. Only one of them is fixable afterwards.

How many photos does a time-lapse need?
The frame count where a photo sequence stops looking like a slideshow, the frame rate that suits slow subjects, and a table of how long each cadence takes to get there.

Progress photos without a tripod, using a shelf
A repeatable full-body setup using a shelf, a book and a strip of tape. No tripod, no remote, no second person, and more consistent than a mirror selfie.

Ghost overlay, grid lines or align it afterwards?
Three ways to make repeat photos line up, compared on what each one actually knows about your last shot. Only one of them has ever seen it.

Why we built a progress photo camera with no server
Progress photos are among the most sensitive images people take, and most apps upload them to a cloud. The case for having nothing to upload to.

Guides and tools, not just posts.
The guides are step-by-step setups. The tools run in your browser and never upload anything. Both are free and neither needs the app.
