Canon EOS 6D Mark II Dynamic Range Talk & Sample Images

Re: Canon EOS 6D Mark II Dynamic Range Talk & Sample Images

For those wanting to switch to the Nikon D750:
https://www.dpreview.com/news/5252259585/nikon-expands-d750-shutter-recall-yet-again-more-cameras-affected
If you look at the comments section the comments sound about the same as those on this forum, but slamming Nikon.

The Nikon D600 had a shutter problem as well (sensor oil splatter), and the D4 & D800 had a lockup problem.

Well, sort of... Yes, the DR of the downsampled 6DII image will be higher, but downsampling doesn't change the DR when the image is captured. IMO, it's the latter that matters – if you have a 13-stop scene, and 12 stops of DR, you've clipped one or both sides. If you then downsample that image until you have 13 stops of DR, you don't get back what you clipped at capture.

I agree with that....sort of . As I understand it the DR discussion is about the level of shadow detail and at the moment I am not sure if this is defined as whether a sensor can pick up the signal at all, or if it is about signal above noise.
If you preserve the highlights, then shadow recovery depends on the artefacts you see when you do so. Some look to a higher DR sensor to recover the shadow (no downsampling needed) but you can also do it by downsampling which mean you can 'uncover' an until-then hidden signal by effectively lowering the noise floor (which I believe this is what the astrophotographers do).

[this is gleaned from bits-and-pieces read over the years so may be incorrect].

Very well put. This is my understanding as well.

Depends what you want your muck ups to look like, but make no mistake this file is not exposed optimally, a -1.33 EC was dialed in yet there is at least one stop of head room unused!

Here is my two minute play in LR, mind you I prefer a 'natural' look over the radioactive HDR style Dan is trying to portray as optimal.

Private, I just had a sense of deja vu !

However this time they allowed downloading of the raw mis-exposure. I presume the flash failed here ? Also the horizon is well off but the image is already so tight around the dog's feet it can't be levelled.

This is a very similar situation to the infamous 5Ds image; underexposed in very low light. Under normal conditions I am sure that the RGB values of 25 - 28 around the girl's neck would easily lift without showing undue noise. However in this case it has made even the bride's face and neck look bad.

Here is a Before/After, to me the IQ is looking pretty sterling. But then I am results driven not click driven....

Yep!

Mind you, one thing I have learnt is never say "can't", you just need to look at the problem a different way.......

1.1 degree clockwise horizon correction to include dogs 'feet'.

I agree that's responded to noise reduction pretty well, but I still think that underexposing in an already dark situation is very misleading as far as the camera's capabilities are concerned.

Shot with the same exposure a D810 is still going to have poor tonality in the guy's blue suit. It's just a bad exposure, full stop.

Clever sod, mine's 1.2

What you do to this?

Edge of stone to water and water and the dog...

Yes, you clean up some noise but push down here, pop up there.. will download and try.

Re: Canon EOS 6D Mark II Dynamic Range Talk & Sample Images

It is interesting to see what you can do and completely agree would be a binner and it is funny they would post an image like that to show how bad the camera is

On the same merit I was hoping like the 7DMKII 5DSR 5DMKIV and 80d the old purple shadow cast and colour noise would be a thing of the past but its not.

We are 20 odd pages in and everyone's arguing but nobody has posted an image.

Plenty out there have a go

Quite a few good high contrast images in the DP image slideshow IMG_0741.CR2 is worth a look.

Like I said the files look very familiar almost feel exactly like the 5DMKIII.

Let me remind you that DPR may not like us to repost their sample images without prior permission.

Did you try the IMG_0087 ?

I just applied an adjustment brush to the darks. Global was WB and NR, nothing else.

I see why you need NR. Suit becomes bad. Don't notice noise so much on SRGB screen but AdobeRGB screen yes.

-100 Highlights, +50 shadow, noise gone. but too dark?

Same here. ISO 100 image with a ton of noise reduction similar to what I usually do to ISO 6400+ images

DPReview have a consistent history of posting deliberately badly exposed Canon images then holding them up and saying "look how bad it is". It is bullish!t, they are liars and cheats and are doing a severe disservice to people who don't realize what DPReview are doing.

On the specific issue of use, I'd argue the reposts fall clearly under the education exclusion in the copyright law. Even if they objected, which they wouldn't because any click is a good click, they'd have difficulty proving infringement on 'samples' they post for download and comparison purposes.

No just a 1.77 exposure reduction to the brush. This is a very easy file to get a usable and natural looking result from.

Clicks.

That is money, Amazon own DPReview they want clicks and sales, doesn't matter what brand, just click and buy.

22 isn't a ton of NR. The image is easy to work with even though DPReview deliberately messed it up.

To be sure, this image has a -1.33 EC, the heavy lifting is a +1.7 exposure lift to the darker areas. If they had put the camera in Highlight Tone Priority and left the EC alone this image would be perfect out of the camera.

Then DPR bashing Canon (a company with the biggest market share) are hurting Amazon .
