Tone CaliperYou think in color.
Tone Caliper lets you edit a photo by working with the colors you can actually see.
Edit by color, not by panel.
Most photo editors make you translate what you see into sliders. Tone Caliper starts with the image.
The colors in your photo appear on a wheel as a soft map. Pick the blue in the sky, the green in the trees, or the warm tone on a wall. Then move it where you want it to go.
Shape the colors that are already there. Push a sky deeper. Warm a highlight. Pull one tone away from another.
Refine by light, not just color.
A color edit doesn’t have to affect every part of the frame. Limit it to the highlights, midtones, shadows, or any range in between.
Warm just the highlights. Cool only the shadows. Treat the same color differently depending on the light it falls in—no brushes or manual selections.
With a color pin active, press H to reveal its selection directly over the photograph as a grayscale preview. Refine the lightness range, check exactly what the grade will affect, then continue shaping the color from the wheel.
See the look.Know how to get there.
Use any photo as a visual guide while you grade. Tone Caliper shows its colors alongside your own, making it easier to see what separates the two images and decide which colors to move, preserve, or leave alone.
Black and white starts with color.
A good black-and-white photo is not just a desaturated color photo.
Tone Caliper lets you decide how each color becomes tone. Darken blues for a heavier sky. Lift greens for brighter foliage. Separate colors that would otherwise fall into the same gray.
Start with classic filter responses like red, orange, yellow, panchromatic, or orthochromatic. Then fine-tune the image by hand.
Open a folder. Start editing.
Tone Caliper works with the folders you already use.
No import step. Open a folder, browse your photos, flag your picks, filter by lens, date, or location, and send any image into the editor.
Start from a look you love.
Browse looks shared by other photographers, save one in a click, and try it on your own photos.
Use it as a starting point, not a locked preset. Apply the look, then adjust the exact colors that need attention in your image.
Save your own recipes too, and build a small library of looks around the way you edit.
Nothing moved. Nothing uploaded. Nothing rented.
Your originals stay untouched.
Your originals are read-only, never moved, renamed, or baked over. Every edit lives separately, so you can rework or reset any photo, any time.
Your photos stay on your computer.
Browsing and editing happen locally on your machine. Your library is not uploaded or used for analytics. Online access is only used for things like trial validation, licensing, and shared recipes.

Questions
Which files can it open?
JPEG, PNG, TIFF, HEIF, and camera RAW — Canon, Nikon, Sony, Fujifilm, Panasonic, Olympus/OM System, Pentax, and Adobe DNG (including Apple ProRAW, Ricoh GR, and DJI).
Does it change my original files?
No. Your originals are read-only — never moved, renamed, or overwritten. Every edit is stored separately in a single catalog file you control, so you can rework or reset any photo, any time.
Does it fit my current workflow?
Yes. Tone Caliper reads the folders you already have and changes nothing on disk, so it sits beside whatever you use now. Think of it as a non-destructive color finisher: point it at a shoot, grade or convert to black and white, and export.
How much is it, and how does the trial work?
Tone Caliper is a one-time $39 while it is in beta — a $20 founder discount off the regular $59, no subscription. The 14-day trial is the full app, editing and export included, so you can try everything first. After you buy, a license key arrives by email and on the confirmation page; paste it into the app to unlock it.
Which platforms does it run on?
Tone Caliper runs on 64-bit Windows 10 and 11, and on Apple silicon Macs running macOS 26 Tahoe or later.
