Canon R6 - CLog 3
I haven't seen an option on the R6 to use CLog2. Only CLog (1) and CLog3. Here's an article that discusses the differences . One thing I would advise is to turn off "View Assist" and view the histogram of the image before recording. You may find that you're not overexposing as much as you think you are. On the R5, I generally shoot +2 EV or even as high as +3 EV before the highlights start to clip in CLog3 mode. "View Assist" seems to clip the highlights so that you can see what kind of exposure you're getting on the low end, at the expense of throwing away all the highlight details that are actually getting captured in the video file.

Looking for Color Grading Advice (C-Log3): canon r6 mark ii
I’ve used an R6ii since it came out for video (recently got an FX6 though. My recommendation would be to shoot in cinema gamut, used the Phantom LUT (their neutral one) and then add a look LUT that mimics the Fuji eterna (at a low percentage) to get those red tones in the right place. Also one note I’ve noticed is even though iso800 is the Base ISO, I prefer to shoot in iso400 at a loss in dynamic range because it makes the shadows looks much more pleasing. More on reddit.com

Canon R6 - Some noob questions about shooting log footage
I am FAR from an expert on this sort of thing, however I have a bit of experience in shooting video in Clog 3 on an R5. I learned a ton from this video from Tyler Stalman , where the biggest thing was learning to do the color grading before the LUT as it affords a far greater dynamic range (6:20 specifically). I do everything in Clog 3, ISO800, and then use ND filters to get the correct shutter speed. Video editing is definitely fun, but also far more time consuming than photo editing. More on reddit.com

Does the R6 iii let you chose your base ISO when shooting Clog3?
Yeah you can definitely choose your base ISO independently from your shooting ISO on the R6 Mark III in Clog3. It's in the menu under the video settings - you'll see options for 800 or 3200 base. Pretty handy feature, not just limited to cinema cams anymore More on reddit.com

r/canon on Reddit: Canon R6 - CLog 3
September 7, 2021 -

So, question about CLog 3 on my R6. Having some troubles embracing this new one due to the ISO 800 base. Most of my video is shot in daylight, and I am finding I am constantly having to max out my ND filters to meet even the CLog 2 ISO 400. I can see the benefit when shooting in controlled lighting, but for any day time shooting it is a tough one to embrace. Further, if I shoot a mix of CLog 2 and CLog 3, I cannot see an easy way to differentiate in Premiere and that makes the Capture LUT process a real pain in the ass.

Any thoughts and suggestions? Is CLog 3 in ISO 400 better than CLog 2 in ISO 400? Probably not, but anyone with experience know?

Thanks!

r/videography on Reddit: Looking for Color Grading Advice (C-Log3): canon r6 mark ii
May 8, 2025 -

I shoot with a Canon R6 Mark II and record in C-Log3. I’ve tried Canon’s official LUTs and experimented with different color spaces like Rec.709, Rec.2020, and Cinema Gamut.

Most of my footage is of animals such as; deer, bears, dogs, ducks, geese, bobcats, etc. all shot in 4K. These videos are just for fun, and I like to share some of them on Instagram Reels and TikTok.

That said, I’ve been struggling to get a good color grade. The few clips I’ve managed to shoot and grade just feel off, colors look strange or flat, and I can’t seem to get that vibrant, natural look. For those working with Canon C-Log3:

  • Do you rely on Canon’s LUTs or use custom ones?

  • Do you manually convert to Rec.709 or use a LUT as a base?

  • What color space and gamma settings do you find give the best results?

  • Any tips for making colors pop in a realistic way?

Would really appreciate any advice or shared experiences. Thanks in advance!

r/canon on Reddit: Canon R6 - Some noob questions about shooting log footage
September 11, 2023 -

Hi all,

I am getting more into the video side of things (mainly a portrait photog) and am having a little bit of an uphill battle learning to work with log.

I have a first gen R6 which can shoot in Clog (709, 2020) and Clog 3 (709, 2020 and Cinema Gamut).

I am finally feeling comfortable on the grading side of things (using DaVinci Resolve Studio 18.5) but am a little confused about exposing properly, esp at night time in low light settings.

Here is what I have gathered to far:

Native ISO for Clog is 400

Native ISO for Clog3 is 800

Coming from the photo side of things I thought that I can bump up the ISO to get the right exposure but this has lead to a lot of noise in the footage.

I am now understanding that for video we must stick to the base ISO…is this correct?

Some videos I have watched mentioning going in multiples of 800…so 800. 1600. 3200.

I think we’re supposed to overexpose log by 1.5 stops but if that isn’t possible due to certain lighting conditions, how can I get the best (min noise) end product?

I have tried denoising in DR and it takes away from the sharpness quite a bit.

Topaz AI Video denoiser does a decent job but takes some of the saturation away from the reds.

However, I want to make sure I can getting everything right in camera so I do minimal denoising later.

Currently here is my workflow

Import into DR > add to timeline > color space transform onto node to move from clog3 cinema gamut to rec 709 and cineon for the first phase > second node, add Kodak LUT from the “film looks” luts.

I think we’re supposed to overexpose log by 1.5 stops ETTR is often messed up. Cullen Kelly has a good video on it here https://youtu.be/aB8ku9ET-dw?si=cN6BMHyDiC6ICkJG If you are going from iso 1000 to iso 2000 to ETTR, you are doing it won't. I am now understanding that for video we must stick to the base ISO…is this correct? No. Will a ISO 800 image have less noise than one shot with half the light at iso 1600, yes. But if you don't have a means to double the light on your subject (or faster lens) then ISO 1600 is going to be your only option. Import into DR > add to timeline > color space transform onto node to move from clog3 cinema gamut to rec 709 and cineon for the first phase > second node, add Kodak LUT from the “film looks” luts. I will ask where you are making your grade at. If it is in the rec709 nodes, this could be causing you problems. I would recommend using the automatic color management added in V17 to grade in DWG. You can grade on the clog side of your first CST. But having a common working space for all cameras is desirable. Cullen has also converted the Kodak and Fuji LUTs to DWG to eliminate the cineon faff I have the R5 (never shot an R6), many people complain about it being noisy, but I haven't seen it. This video is at obviously quite dark and even has slow motion. I think it worked well https://youtu.be/OhA6X-o8KXE?si=bVS94nFq_HGU-Ba0 Iso 12800 is going to be noisy, no doubt. But if you can't get a good image at 1600-3200, I think you have a workflow problem.

r/canon on Reddit: Does the R6 iii let you chose your base ISO when shooting Clog3?
January 26, 2026 -

Hello, I can't seem to find this setting in Canon's camera manual and I don't have a camera to try it on. I'm wondering if I would be able to shoot at 800 ISO but with 3200 ISO set as the base ISO. I've heard the R6 iii has dual native ISO in Clog3 at 800 and 3200, but I'm not sure if you can choose which base to use independently of the ISO you're shooting in.

I'm considering buying the R6 iii and I was watching this youtube video that explains the benefit of choosing the base ISO for dynamic range. Seek to 4:53 to for the explanation.

I'm not sure if this is only a feature available on dedicated cinema cameras.

r/canon on Reddit: CANON R6 - 10 bit CLOG 3 confusion
October 25, 2022 -

Hi there,

I notice there has been a fair amount of confusion on this subject and I am yet to find a definitive answer.

I purchased a monitor with a wide P3 colour gamut, I plan to use this as my primary colour grade monitor but I would like some clarification:

  1. I shot some footage for a Music video with BT709, is this the same as REC709 and such although shot using CLOG 3 does this give me limited creativity in post?

  2. Next, what is cinema gamut and such does changing to this give me the widest colour grading potential?

That should be all for now, I simply want a definitive answer for myself and those wondering in the future.

Many thanks

A color space has 3 parts, a set of primaries(definitions of red, green, and blue for RGB spaces), a white point, and a transfer curve (sometimes called a gamma curve). See https://hg2dc.com/2020/01/08/question-17/ BT709 Clog3 has the primaries and white point of Rec709, but it has its own transfer curve which is designed to preserve the light ratios of the original scene, it just kinda compresses them somewhat. The idea is you can invert that log transfer curve and arrive back at a radiometrically linear frame Cinema gamut is an alternate set of primaries you can use in place of rec709. They are MUCH wider - in fact, all 3 are imaginary - which avoids most loss of scene colors and allows you to convert down to your output space after you've done the grade. It's especially handy if that output space is something wider than rec709, such as DCI-P3 for film deliverables, or Rec2020 for HDR video. It does come with a downside that YOU are now responsible for doing this downconversion correctly instead of letting Canon handle it, and...well, sadly a lot of software doesn't do this right - ACES doesn't bother to really do it all - so it's not like shooting in excessively high res or bit depth where you can just effortlessly downscale it and it works nicely. On an additional note, a P3 monitor will not show Rec709 footage the way it will look on an actual TV, or even a youtube video on an sRGB monitor. You'll need either a dedicated rec709 grading display, or to make sure a Rec709 > P3 conversion is being performed on the fly to your viewers by the grading application's color management. This may or may not be the default behavior, so don't assume it's being taken care of for you. (ex, Resolve + Windows it will NOT be done for you!) Welcome to color science, enjoy your stay

To add to conversation: Your monitor should always be set to the same specs your output video is. I use eizo cg series monitor that has awesome color gamut, but since I mosly work in rec709 gamma 2.4 D65, it is set exactly as that. Professional monitors are nice, because you are able to set them for the project needs. Edit: don't forget that is has to be frequently color calibrated.
