Canon Log Image Quality
With Canon Log, movies may be affected by horizontal banding, depending on the
subject or shooting conditions. Record a few test movies and check the results in
advance. In particular, noise may become more noticeable if you enhance the contrast
when color-grading your movies.
With Canon Log, skies, white walls, and similar subjects may be affected by noise or
uneven gradation, exposure, or colors.
Horizontal banding is more likely to occur when recording somewhat dark, flat subjects.
This image noise may even occur at relatively low ISO speeds around ISO 400.
If noise is noticeable, try recording under brighter conditions and adjusting brightness in
color grading. Noise can also be reduced by recording at ISO speeds lower than ISO
400, although dynamic range is narrower.
Caution
General Canon Log shooting precautions
With Canon Log, autofocusing may be more difficult for subjects under low light, or
for low-contrast subjects.
Noise may appear at image edges if [Peripheral illum corr] in [ : Lens
aberration correction] is set to [Enable] when Canon Log is set.
Canon Log 2 and Canon Log 3 are not supported.
Histograms of images captured with [Canon Log] set to [On] are not based on
images as converted for View Assist display. Image areas shown in gray in the
histogram roughly indicate signal values that are not used.
ISO 100–320 is not available when recording RAW movies with Canon Log set.
Note
Playing movies recorded with Canon Log
View Assist is not used during movie playback.
