Do the porting of raw overexposure detection will be ever available for the 550D and other models ?  ::)
If you think it's impossible, you have lost beforehand

Ported to 600D but black level auto detect isn't working right.

I don't quite get this, maybe the answer is buried in some thread - will there be full raw support for older cameras like the 60d, i.e. overexposure/histogram & video?

Why not?

I simply don't know if the raw stuff is doable on digic4 cameras (I didn't follow the development), and since raw video seems to be available only for newer digic5 cameras I was wondering if this is a coincidence or if it's not possible for 60d and the like...

Black level got fixed... working on many digic IV cameras... you just have to find the bins.

Hi,

It seems to me that files that are clearly not overexposed appear to be so with the RAW blinkies/zebras. The RAW histogram seems right though. In Lightroom, the raw file http://shayok.com/tmp/raw-hist/_MG_1799.CR2 requires only .25 stop underexposure in Process 2010 and none at all in Process 2012 to get all the highlights in the middle of the image. I got screenshots in ML, but unfortunately it doesn't capture the blinkies (VRAM0). VRAM1 and VRAM2 show my RAW zebra/hist settings.

I don't see any overexposure warnings in your screenshot.

As I said the blinking warning does not show up on the screenshot. Other than doing a video of the LCD, is there any other way of showing you?

If it's blinking, it's from Canon, turn it off...

Hi,
I'm a ML virgin but extremely keen to get a RAW histogram for use on my 5dIII. I do a lot of clean white interiors and mostly end up bracketing to get as good a ETTR exposure as possible, then sometimes use RawDigger to find the one closest to the right. I worry it looks a little unprofessional in front of clients and usually to a 'normal' exposure to give them an idea of what the finished image will be like.

I'll subscribe to the thread but just wanted to clarify where its at with regard to this functionality on the 5D III?

The [DONE] in the thread title is a pretty good hint  ;)

if i disable the liveview and the review (because eats a lot of battery in a canon 7d)
will ETTR work in a timelapse?

Sorry for re-opening this old thread.

Just wanted to express to A1ex and others:
The extraordinarily rapid development of RAW-based histograms/blinkies/zebras/etc (and then Auto-ETTR) is among the top two most impressive feats of software development expertise I've encountered in 45+ years of paid and FOSS s/w development. Beyond humbling.

Many years ago I was with Commodore Data as a Systems Manager for Commodore 64. When it died in the mid-90's I worked as a general journalist, but was of course interested in software developement. And I agree. The ML Universe is an outstandingly fine invention, done by a number of extremely well-skilled and innovative people. Way above and beyond the call of duty.

Agreed and I am actually loving the recent improvements made to RAW histogram ... This RAW OE warning is just icing on this fabulous cake! [emoji6]
