Standard, Neutral, Vivid … Flat Monochrome and the twenty Creative controls can be adjusted in place, exactly like the camera's menu: Quick sharp or the individual Sharpening / Mid-range / Clarity, Contrast, Brightness, Saturation, Hue, and — for monochrome bases — Filter effects, Toning and Toning density. A control you have adjusted shows an asterisk and its deltas in the list. RESET reads the camera's factory values back.

Create a Custom Picture Control from any base, name it (up to 19 characters, as on the camera) and write it to one of the nine slots — or open an existing slot to edit, rename or delete it. Slots are shown with the names stored on the camera and follow renames made on the body. The LIBRARY keeps looks on this phone so you can write the same look to another camera.

ON CAMERA (default): every change is written to the camera as you adjust and that control is made active, so the live view shows the look. Switch to PHONE ONLY while recording, or to prepare a look without disturbing the active control — nothing reaches the camera until UPDATE / WRITE. Leaving the editor without writing restores exactly what the camera had before.

Press and hold to see the original: the app writes the control's previous values back to the camera, so the live view shows the real before — not a frozen frame. Release and your edit is applied again.

Adjust a Picture Control on the camera body while the editor or picker is open and the app follows: the camera announces the edit and the values update within a second. Filter effects and toning are greyed out unless the base is a monochrome control — the editor says which bases enable them.
