\u96c6\u4e2d<\/div>
Focus-peaking overlay. Highlights in-focus detail with a colored stroke. Long-press for the Focus assist menu: Peaking color (a swatch window that stays open and docks at the screen edge so you compare colors on the live feed \u2014 X returns to the menu), Line thickness (Thin \/ Medium \/ Thick \u2014 the stroke width only, detection is unchanged) and 'Threshold & tuning\u2026', which opens a live slider over the feed: 0 shows only the crispest, highest-contrast edges, 50 is the factory detection, 100 also lights up soft edges and fine texture such as hair or fabric. Pills in the same drawer: THIN\/MEDIUM\/THICK, GRADED (stroke strength follows sharpness instead of a solid line) and TONE (relaxes the detection on flat profiles \u2014 N-Log, Log3G10, HLG \u2014 so the same slider position looks alike on every tone). Everything here is part of an app preset. In fullscreen, long-press a Quick Button bound to Focus to cycle the peaking color on the fly.<\/div><\/div><\/div>
\uf451<\/i><\/div>
\u30b7\u30de\u30a6\u30de<\/div>
Exposure zebras. Diagonal stripes over areas above your set brightness threshold \u2014 separate Highlight and Middle-Grey zebras with their own colors and levels. Long-press for modes, levels and 'Auto Standard per Tone': ON loads the standard levels whenever the codec\/tone (or view LUT) changes; OFF remembers your own levels separately per tone.<\/div><\/div><\/div>

\uf55f<\/i><\/div>
\u30d1\u30f3\u30c1<\/div>
Focus punch \u2014 the BODY's live-view zoom (LiveViewZoomArea), not a digital crop: tap cycles Entire display \u2192 100 % \u2192 200 % \u2192 400 % (only the levels this body offers \u2014 the list comes from the camera itself), hold picks a level directly. Long-press a level in the sheet to star it: one favourite makes the tap toggle that level \u2194 Entire display; two or more make the tap cycle through the starred levels only \u2014 star "Entire display" too if you want Off in the loop. The punch follows the AF point: Tap-AF moves it. "Snap to detected subject" (row at the bottom of the sheet): On punch-in centres the zoom window on the face \/ eye \/ subject the body has detected the moment you punch in; Follow keeps re-centring while the subject moves; Off leaves the window where the focus point is. Works with the body's AF subject detection and, on bodies that have it, MF subject detection. The tool is hidden on bodies that do not announce live-view zoom. Punch can also sit on a fullscreen Quick Button A \/ B (Options \u2192 Video or Photo tool table): tap behaves like the HUD button, long-press opens the level sheet, and while the body is zoomed the button lights and prints the current level (100% \/ 200% \/ 400%). While recording the body allows only Entire \/ 100 % (no change at all in RAW codecs), and the camera magnifies its own monitor only \u2014 the app feed stays full frame while recording or on HDMI.<\/div><\/div><\/div>

Framing guides. Aspect-ratio markers (2.39:1, 1.85:1, 4:3 \u2026) drawn over the feed. Long-press to choose ratio and style, dim everything outside the active frame, or magnify the live view so the guide fills the screen (uniform scale, single guide).<\/div><\/div><\/div>

Z\u30d5\u30a3\u30fc\u30eb\u30c9<\/div>
Z Field exposure assist. Colors the image by exposure zones from crushed shadows to clipped highlights \u2014 a light-meter view of the whole frame. Long-press for the menu: 'Edit colours\u2026' opens a live panel over the feed where you pick one color per stop (the stock Nikon Z palette first, transparent, or a custom color) and watch the overlay and legend change as you tap; 'Save Current as Preset' stores that palette under a name, tap a preset to apply it, long-press to rename or delete. Presets and the current colors are part of an app preset. See the 'Z Field \u2014 Exposure Assist' section below.<\/div><\/div><\/div>
\uf27d<\/i><\/div>
F.\u30ab\u30e9\u30fc<\/div>
False color. Maps IRE brightness ranges to 10 reference colors \u2014 the legend shows the exact 0-100 IRE range for each color. Long-press for the menu: 'Edit bands & colours\u2026' opens a live panel over the feed (right edge in landscape, bottom in portrait) where you tap a band for its color (stock palette, transparent, or a custom color) and move its START level with \u2212 \/ + \u2014 the overlay and legend follow instantly, so you see exactly what you are about to save. 'Save Current as Preset' names and stores those bands + colors; tap a preset to apply it, long-press to rename or delete. 'Auto Standard per Tone' ON loads the standard cine bands whenever the codec\/tone changes (hand-editing or loading a preset switches it OFF so your setup isn't overwritten). Presets and the current bands are part of an app preset.<\/div><\/div><\/div>

3D LUT<\/div>
3D\/1D LUT preview. Applies a color-grade LUT to the monitor feed only \u2014 recording is untouched. Long-press to pick or import .cube files. Accepted: standard Adobe\/DaVinci\/RED .cube files \u2014 any 3D size from 2\u00b3 to 128\u00b3 (17, 33, 64, 65, 125 all load) and 1D LUTs (LUT_1D_SIZE, expanded on import); TITLE and DOMAIN_MIN\/MAX are honoured. Not supported: .3dl, .csp, ICC. 33\u00b3 is the sweet spot for live view; larger cubes work but take a moment longer to import and to push to background windows. Organise the menu: '+ New folder\u2026' creates your own folders; long-press a folder to rename or delete it; long-press a LUT for Move to folder\u2026 \/ Rename \/ Delete. Inside a folder, '+ Import \u2026 into this folder\u2026' files a new .cube there. Bundled packs and LUTs you delete are only hidden \u2014 Options \u25b8 Display \u25b8 Restore bundled LUTs brings them back. Folders and renames are library organisation and are not part of an app preset.<\/div><\/div><\/div>

\u30ec\u30fc\u30c0\u30fc<\/div>
Exposure radar \u2014 a per-channel clip \/ crush meter. Each R\/G\/B bar counts only the pixels that are genuinely clipped (at the tone's measured clip level) or genuinely crushed (below the Z Field's \u22126 zone for that tone), so SDR, N-Log, HLG and R3D are each judged on their own curve. A bar starts filling and its lamp lights once more than 3 % of the frame is clipped or crushed; the noise bar estimates sensor noise in the darkest areas.<\/div><\/div><\/div>

Slow motion (S-MO). Switches the camera into its high-frame-rate capture modes \u2014 the picker lists only the resolution \/ frame-rate pairs the body actually supports, and the resolution and frame-rate chips in the top banner update each other so an impossible combination can never be sent.
