can you post a link to your screenshot(s) of your problem as requested please:

Happy to help but when you say post a link - where do I upload the screenshots? Also please be specific about what you would like to see - shots that show the problem happening, or that test that raw histogram issue with the three different ISOs?
Thnx

Which build were you using @pmus2017?

What I have to go through every feature to see if it works? Sorry don't have time to do that & don't use many features. Happy to give any more info needed about this specific problem though.

It is really not clear where to enter a bug report. At the top of this thread it talks alot about "filling in NOT OK" but doesnt say what that means nor link to anywhere?

well I cannot see any difference between the three settings. The clip warnings appear to keep the same values across the three as well. Certainly no obvious change to my eye

That's correct. The easiest way to check for this bug is in movie mode, with some raw recording module enabled (but the same bug can affect raw overlays in photo mode LiveView as well; it's just harder to diagnose there).

This was (hopefully) fixed in all models recently (until then, some models worked, others not, and it wasn't exactly the kind of bug that gets reported often).

OK so you mean does the histogram shape stay identical when switching between those three ISOs? I can try switching on RAW but on the 70D when you press the ISO button a canon slider menu appears to let you select the ISO setting and the histogram disappears. It is therefore almost impossible to accurately compare histograms between ISO settings. Any suggestions?

@pmus2017: does the raw histogram change in movie mode between ISO 160, 200 and 250?

It should stay unchanged at these 3 values. If it changes, that's a bug (and its most obvious side effect would be missing clipping indicators at ISO 160 multiples).

I am not shooting in RAW & I believe you cannot use the RAW histogram unless you are? I am using these indicators in movie mode though

OK well as I don't have a Phd in digital imagery that didn't really make a lot of sense, but I think you are trying to indicate that this assertion that 160 multiples are the native ISOs of Canon cameras is wrong ( despite the fact that I have read it / seen it mentioned in many places online ). That being so, I can of course avoid the 160 multiples that are causing the issue which is great, but the problem still stands.

Hi. Big thanks to all those who develop ML. Cracking tool. Just bought the 70d and having issue with ML exposure tools. In zebras and clip warning in histogram, they are only working at certain apertures. On certain apertures (different for different Sigma lenses) they don't display despite having displayed on smaller apertures ( so should be worse ). If I click through apertures from largest to smallest, every three or four settings they vanish then return as I move to the next  ( until exposure gets down to level where they should not be showing). It is identical issue with both tools at the same time. Any advice appreciated. Can't see this in the list of known bugs at top of thread.

OK I have identified when it occurs now - if I am on the native ISOs ( 160, 320, 640, e.t.c ) then it always happens. As I increase/decrease the aperture, every few stops the zebras & clip warnings disappear despite obvious clipping in the image. I have tried it on both Sigma & Canon lenses and the same problems occur with both types of lens. If i choose 100 ISO or any non native setting the problem does not appear. Obviously I can stick to the non-native ISOs but of course I want to ONLY use native ISOs to reduce noise!

Any suggestions?
Thnx

I do but problem seems intermittent as not doing it now. Was the same yesterday. Did it for a while then resolved itself. Will try to figure out when it happens & whether there is anything I am doing that may trigger it.

Beautiful film. I am a total beginner at colour correction/grading. I have Davinci Resolve 12. Do you use a specific LUT or look? Can you give a little detail about your workflow from flat image to colour graded. Any advice most appreciated!
