CHRO-MA-SMITH — Guide

Film looks, grain, halation and colour grading for your photos, with a photo gallery built in. Everything runs on your own device — nothing is uploaded, and every edit, LUT and export is processed locally.

Getting started

Gallery

Studio

The tool rail on the right groups every tool into six stages. Each stage opens with its tools folded; click a name in the row under the stage title to jump to a tool and open it. A tool with a square around it in the rail has been edited.

Look

• Preset — 113 film looks (C41 still, cinema, reversal, instant, black & white and more). Hover a look to preview it on your photo, click to apply, and set its Strength.
• Input & print — set Input to V-Log (Lumix) for V-Log stills so a normal Rec.709 look applies correctly. Highlight response and Print change how bright areas roll off.
• Apply LUT / LUT chart — drop your own .cube, or use the LUT chart to turn any Lightroom preset into one (see the note below).
• All FX (top bar) — applies your chosen effects in one click. The ▾ beside it picks which effects, their strengths and the look.

Light

• Histogram — live levels with shadow/highlight clipping warnings; click a clip marker to show clipped areas on the photo.
• Basic — exposure, contrast, highlights, shadows, whites, blacks, temperature, tint, vibrance and saturation. The eyedropper sets white balance from something neutral; Auto sets levels and white balance for you.
• Curves — master and per-channel point curves. Click to add a point, drag to shape, double-click to remove.
• Halation — the red-orange glow real film gives bright edges. Shadow protect stops dark details inside bright areas flooding red.
• Bloom — soft highlight glow.

Colour

• Mixer — shift the hue, saturation and luminance of eight colour bands independently.
• Wheels — tint shadows, midtones and highlights.
• Point colour — pick one exact colour in the photo and change only that.

Texture

• Noise, Sharpen, Lens — noise reduction, sharpening and lens correction.
• Masks — radial, linear, brush and AI masks (subject, sky, skin) with their own exposure, colour and tone. Show on photo draws the selection; O cycles its modes.
• Grain — film grain, shown at its true export size in the 1:1 view.
• Artifacts — dust, hairs, scratches and light leaks; Reshuffle re-rolls their placement.
• Effects — vignette, clarity, texture and dehaze. Retouch removes spots and blemishes.

Skin Tone mask (even out an uneven tan)

• Most colour controls shift every tone by the same amount, so a patchy tan stays patchy. Uniformity pulls the selected skin toward one target: areas far from it move a lot, areas already close barely move.
• Add a + Skin mask and click a mid-tone patch of skin. Move the shape so it covers the person you mean — colour alone can't tell skin from sand or wood. Use + Brush or − Subtract for anything the shape can't isolate.
• Set Show on photo to Selection, then shift-click each different kind of skin (matte, shaded, paler, pinker) until it all reads red. A patch that is only weakly selected barely moves.
• Keep Feather low so colour, not position, decides how much each area moves.
• Target: Match pick evens out the tone you clicked, Swatch offers the Monk Skin Tone scale, Custom takes any colour. Preserve modeling keeps the natural shading — start high.

Output

• Crop — aspect presets, rotate, flip and Straighten (fine steps near level). Auto level finds the horizon; Set region… tells it where to look. Pick a Grid to see it on the photo.
• Border — two stackable frames (inner and outer), including film-edge styles.
• Canvas — mats the photo onto an aspect-ratio canvas (4:5 stops Instagram cropping a 2:3 photo), on a colour or a blurred copy of the photo.

Info

Metadata (camera, lens, exposure, size) opens first. Keywords and Tags (auto tags plus People & Pets) sit below it.
