Picture Profiles and Exposing for Log

A log or flat profile intentionally records a dull, low-contrast, slightly gray-looking image on purpose, so it can be graded into a final look later without losing highlight or shadow detail in the process. Shot at a normal exposure, that flat image looks worse than it needs to and often crushes shadows the moment you try to bring contrast back in an edit. Exposing correctly for log is a specific skill, not the same meter-to-zero habit from Lesson 1, and it’s the one that decides whether your flat footage is actually gradeable or just permanently underexposed and gray.

Not every entry body has true log (S-Log or C-Log style curves are often reserved for higher-end models). Check your menu for a Log or Log Gamma option under Picture Profile. If it’s not there, find the flattest picture style or picture profile available, turn contrast and saturation all the way down, and treat this lesson identically, the exposure discipline is the same regardless of which flat curve you’re using.

Turn on your histogram or zebra display (zebras show diagonal stripes over areas at or near a chosen brightness threshold, useful for spotting clipping fast). With the flat profile active, meter the scene to 0 the way you learned in Lesson 1, then deliberately move exposure brighter by 1 to 1.5 stops, using shutter speed or ISO as the adjustment (aperture should stay wherever your creative spec calls for it). This is called exposing to the right, and it protects shadow detail in a curve that otherwise crushes blacks easily when captured too dark.

Watch the histogram as you brighten. The whole shape should shift right, toward the highlight side, but stop the moment any channel starts climbing the right wall, that’s a clipped highlight and log footage clipped in-camera cannot be recovered any better than normal footage can. If your specific log curve’s documentation gives a different recommended offset than 1 to 1.5 stops, follow that instead, this range is a safe generic starting point for common consumer implementations, not a universal law.

Record 10 seconds. On playback, confirm the histogram sits shifted right without wall-hugging, and that the shadow area in your frame still shows real, recoverable detail rather than a flat black block.
