Log video is footage recorded with a logarithmic tone curve designed to preserve a wider range of tonal information for grading later. It often looks flat or low-contrast straight out of the camera because it is intended to be transformed into a finished look during post-production. Sony describes S-Log as a gamma curve optimised for footage that will be graded. Read Sony’s S-Log guide.

Why record in log?

When a scene has bright highlights and deep shadows, log may give a supported camera more room to retain detail across the image. This can help if you plan to adjust contrast and colour to match multiple cameras or create a particular look. The exact result depends on the camera, recording format, exposure and grade; “log” alone does not guarantee more usable dynamic range.

Log footage is not a ready-to-publish picture profile. Sony notes that S-Log images require dedicated grading software or an editor with grading tools. Your project needs an appropriate conversion or colour-management workflow, and you should monitor how the footage looks while recording.

When standard video may be simpler

If you need a quick turnaround, do not plan to grade, or are recording a simple one-camera tutorial, a standard profile may be easier. Log footage can show noise more clearly in dark areas, and an unsuitable exposure or missing conversion can leave the final picture washed out. Sony specifically warns that noise in shadows may be more noticeable with S-Log than with other gamma settings. See Sony’s support note.

Before a paid shoot, make a short test from recording through export. Check exposure, monitoring LUT or assist settings, colour space, editor support and final delivery. Use your camera manual for the correct profile and base settings; S-Log, V-Log and other log curves are not interchangeable names for one universal format.
