For a start, it would mean that the bottom three stops of your file would be a noisy mess, but it would also encourage you to use an inappropriate exposure.Ĭ-Log is designed to accommodate around 11 stops of DR. And there are a number of reasons why more is not always better.įirstly, there's simply no point using a Log curve that encodes 15 stops of light if you sensor can only capture 12 before the signal becomes indistinguishable from noise. More precisely, Log curves are designed to encode a pre-determined number of stops of light. In the previous section I wrote that Log curves are designed to retain similar amounts of information about every stop of light you captured. Colors are also desaturated, to reduce the risk of saturated parts of the scene clipping and hence losing flexibility when color grading. The simplest way to think of Log files is like JPEGs but with tone curves designed to share their data values out more equally between the number of stops you captured. Crucially, it tends to be relatively small, which is valuable in video: when you're measuring file sizes in data per second, then the clock is ticking from the moment you hit the button. Log is an attempt at a middle ground between these two: it's subject to a lot of the processing and compression that a JPEG file is, but has been expressly designed to retain enough information about the original capture to remain flexible. In stills photography we generally choose between JPEG files (a small and efficient compressed format but one that has limited editing flexibility), and Raw files (larger but retaining the greatest flexibility). To understand why cameras have different Log profiles, it's worth going back to basics to explain why videographers shoot Log at all. In doing so, we hope to make clear why cameras sometimes offer multiple Log profiles, to help you decide which one to use. In this article, we're taking a closer look at C-Log3 and how it differs from the existing C-Log profile. With its latest firmware, the Canon EOS R5 gains the Canon Log 3 profile for video.
