Basic Correction
The top section handles the technical fixes. Input LUT applies a conversion LUT before anything else, which is where a camera maker’s log-to-Rec.709 file belongs. Auto is Adobe’s automatic colour and tone correction; Adobe says it works on log clips too, and the Intensity slider scales it back. White Balance holds the eyedropper with Temperature, Tint and Saturation, and the tone sliders below it shape contrast.
Creative
Look loads a creative LUT or one of Adobe’s presets, with its own Intensity. Underneath, Faded Film, Sharpen, Vibrance, Saturation, the Shadow Tint and Highlight Tint wheels and Tint Balance let you split-tone without leaving the panel. Vibrance is gentler than Saturation on colours that are already strong, which usually includes skin.
Curves, Color Wheels & Match, HSL Secondary and Vignette
Curves pairs RGB Curves with five hue and saturation curves: Hue vs Sat, Hue vs Hue, Hue vs Luma, Luma vs Sat and Sat vs Sat. Each has an eyedropper that drops three points around a colour you click, which is the quickest way to grab one hue. Color Wheels & Match holds three-way wheels plus the shot-matching tools. HSL Secondary builds a key from hue, saturation and lightness for a targeted correction, and Vignette shades or lightens the frame edges.
Where your own LUTs go
Browse works for a one-off, but LUTs you use often can sit in a folder Premiere reads at launch. Adobe gives these locations for the current user: on a Mac, ~/Library/Application Support/Adobe/Common/LUTs; on Windows, AppData\Roaming\Adobe\Common\LUTs inside your user folder. Inside it, files in a Creative subfolder appear in Creative > Look, and files in Technical appear in the Basic Correction Input LUT list. All-user folders exist too and need administrator rights.
