Custom picture files on the camera enable you to adjust color tones in movie recording by applying a combination of settings (gamma/color space, color matrix, and look files), mainly in preparation for post-production processing.
- You can select a custom picture file to record movies with your preferred image characteristics.
- Preset custom picture files can be edited to create new ones.
- To adjust movie color tones, you can register look files.
Caution
- Applying custom pictures may change the metering level.

Canon Log Image Quality
- With Canon Log, skies, white walls, and similar subjects may be affected by noise or uneven gradation, exposure, or colors, depending on the subject or shooting conditions. Banding or noise may also be noticeable in dark image areas.
- Noise may become more noticeable if you enhance the contrast or edit images in similar ways.
- Record a few test movies and check the results in advance.
- Image quality may improve if you change the ISO speed or, in post-production, perform color grading.
Caution
With Canon Log, autofocusing may be more difficult for subjects under low light, or for low-contrast subjects.
Difficulty in autofocusing can be reduced by shooting near maximum aperture or using a bright lens.
- Noise may appear at image edges if [Peripheral illum corr] in [: Lens aberration correction] is set to [Enable] when Canon Log is set.
- Histograms with [: HDR/C.Log View Assist.] set to on are not based on conversion for View Assist display. Image areas shown in gray in the histogram roughly indicate signal values that are not used.
