White balance — fine-tune, favourites & spot measurement

[IMAGE / VIDEO: White balance — fine-tune, favourites & spot measurement — screenshot / clip]
WB ADJUST
Open the WB sheet and tap ADJUST… at the bottom: a small window appears over the live view with the camera's own A–B (amber–blue) and G–M (green–magenta) fine-tune pad for the current white-balance mode — every step is written to the camera at once, so the picture changes as you drag. Drag the window by its header to park it anywhere; its place is remembered. RESET returns to the centre; MORE… opens the full White Balance screen.
Preset manual d-1 … d-6
The WB sheet keeps a single Preset manual row and shows the slot the camera is on (d-3 · your comment). Tap it to choose any of the six slots: each shows the comment stored on the camera and whether it has been measured, so the names travel with the camera to every phone. ADJUST / MEASURE… at the bottom opens the White Balance screen for comments, locks and spot measurement.
White Balance screen
Shows the mode being adjusted (photo shooting menu or video recording menu — the camera keeps them apart) and the sub-types where the camera has them: Auto 0 / 1 / 2 (keep white / normal / keep warm) and the seven fluorescent lamps. In Preset manual the six d-1 … d-6 slots are listed with their comment (editable, as on the camera), each with its own fine-tune and a padlock — a protected slot cannot be overwritten or re-measured.
WB favourites
Tap + to keep the current look — mode, sub-type, Kelvin and fine-tune — under a name on this phone. APPLY writes a favourite to any connected camera; the bin icon deletes it. With the gang on, an applied favourite is sent to every ganged body.
MEASURE A SPOT (Preset manual)
Photo or video mode — the camera must already be on Preset manual (PRE): the button and the d-1…d-6 list appear only then, exactly like the camera's own menu. Tap it for the chosen d-slot: the camera enters its spot-WB standby and the app mirrors the camera's measuring frame over the live view. Tap a white or grey area of the picture (TAP-AF need not be on) — the camera measures that spot, stores the result in the slot and the frame reports OK or Unable to measure. CANCEL leaves standby. A protected (locked) slot refuses the measurement: unlock it first.
MEASURE WHOLE FRAME (photo mode)
Photo mode only, on Preset manual: the same measurement the camera makes when you press the shutter in PRE standby — the whole frame is averaged into the chosen d-slot and no picture is saved. Fill the view with a white or grey card, then tap. The result R / B gains appear in the slot list; a protected slot refuses it.
