10I want to document my work with photos

Open your project and tap Photos. Every picture of the piece sits here in one grid, with the Primary one badged. Each photo has a ⋮ button in its corner for the things you can do to it.

Take Photo opens the camera; Choose from Gallery opens your photo library, where you can pick several at once. A project with no photos yet says Add Your First Photo and offers the same two buttons.

Tap any photo and it fills the screen. Pinch or scroll to zoom - the percentage in the corner tells you how far in you are - and the strip along the bottom moves you between photos. The play button runs them as a slideshow, which is a pleasant way to see a long project from cast-on to bind-off.

From a photo's ⋮ menu, Reorder Photos opens a screen where you drag them into the order you want, and Move Up / Move Down nudge a single photo one place without opening anything. Progress shots in order and the finished piece last is the usual arrangement - though the first photo is the one everyone sees, so many people put the best one there instead.

In the full-screen view, the pencil beside the caption opens Edit Photo Information: a Caption of up to 500 characters and a Copyright Notice of up to 100. Captions are what make a project readable a year later - "after blocking", "sleeve detail", "before I ripped it back".

A photo's ⋮ menu offers Make Primary. The primary photo is what appears beside your project in lists, in search results and on other people's screens, so it is worth picking deliberately - usually the finished piece, in daylight, on a plain background.

A finished-object photo often has a person in it, and Ravelry is public. Turn on Auto-blur faces as you add photos, or use Blur Faces on one you already have. The faces are found and blurred on your own phone - nothing is sent anywhere to be analysed - and you see the result before anything is uploaded.

Cropping a photo that is already on Ravelry would normally cost you resolution, because you would be cutting into the copy on screen. Edit from High Resolution, in a photo's ⋮ menu, fetches the full-size original first, so the crop comes out of the whole photograph. Also phone and tablet only - in the browser the app tells you so rather than quietly giving you a smaller picture.
