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

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.

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?

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.

You mess up dog shoulder with EV+1.77. Not natural.

In your opinion. It is a subjective adjustment that took a few seconds, if you want to change the dogs shoulder make a small adjustment brush, none of this is difficult or time consuming.

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

Shhh! Don't tell them then :P

OK, I won't.
;)

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.

What is the benefit tho? Just stupid.

Clicks.

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

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

That doesn't matter, people will still click Amazon via DPReview, it doesn't matter if they buy the Canon or a Fuji etc it is just about sales. Garbage like this generates clicks, clicks generate sales, sales generate the income. It is no more complicated than that.

The thing is that no amount of Canon crap would make me buy Fuji crap. I'll just keep my old camera :)

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

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.

When I'm lazy it's like this

Don't like brush. Bad side effect.

Try Exposure +0.7, Highlights -100, Shadows +45, NR luminance +50.

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).

Just to clarify, while astrophotographers do lower the noise floor, it's generally not done through downsampling, but rather through averaging multiple exposures (and subtracting averaged dark frames).

Then again, DxO had been publishing data showing Canon sensors performing worse than their competitors for years before DPR started their 5-stop pushes. Neither seem to have affected Canon's market dominance.

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

Tried my dirty fast exposure blending. I processed the RAW into two separate TIFF/16bpp files, one for shadows, one for highlights and then use EasyPanel to create luminosity masks. Three layers bleding. Time to complete was under 5 minutes. It's far from ideal, but on a smaller print, it should still be "usable" enough.

And if the camera had better DR, you wouldn't have to do that.
Or, the image would have looked even better after your (skillful) post-processing.

Overall, what you've shown here is that the dynamic range deficiencies of the 6DII are not an issue for someone as skillful as you.

This wouldn't be an issue, if the image was exposed better to start with. Processing bad input image will only produce mediocre result at best. You have to have good input image to make a great output. And even Sony sensor would have had trouble with that exposure.

I just tried playing with sliders to find clipping points. Black clipping point is at +1,5 EV while white clipping point is at -2.33 EV. That's huge dynamic range in that scene and EVERY current camera out there would have had trouble capturing that scene. The optimal way to capture all detail in such scene is exposure bracketing and then exposure blending in post. GND filter is not an option here for obvious reasons. They shoul've capture same scene with e.g. A7r II, so we could play with both files alongside each other. My guess is that even Sony would have crumbled upon heavier edits as that scene is simply too much for any sensor currently out there...

But hey, sometimes that one stop of DR makes all the difference. Just like how sometimes a broken analog clock shows the correct time of day...for 2 of the 1,440 minutes.

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

I'd have to agree with that Neuro, every extra stop of DR makes a difference. I seem to have spent a lifetime, when shooting a client on a sunny day, either using off camera flash or mostly simply re-composing to avoid the harsh highlight. The higher the DR of a camera the less I have to do that....little by little maybe. The extra DR of the 5D MklV was one of the principal reasons I upgraded from the 5D mklll. It was that or I was closely monitoring Nikon's D750 to cover high DR situations. So, thank you Canon for the 5D MklV it saved some money and hassle.
Ultimately I could get by without 14 stops of DR, I have done for a long time with the 5D, then the mkll and then the mklll. It just makes life a little easier, expands the options a tiny bit. The 6D mkll will do a job and do it well, a little extra DR would just make life a little easier.

Yes ... but it wasn't.

S**t happens, so sometime you need to fix things that weren't supposed to happen.

And this is precisely where having more DR is really useful.

That still doesn't make it an honest representation of what a skilled photographer can do with a 6D2, which is how it's being interpreted. And, I believe, how it was intended to be interpreted.

Sure, more DR is always useful. Unless, like at that scene, DR is simple too much to handle for ANY camera. You would either need fill-in flash, reflector or expose for the skin tones. That photo is simply botched up and no camera could have saved it in the first place...

I tried downloading the RAW files and was not able to open any of them in LR. How were you able to do this?

+1. I'm a 99% of the time available light guy, and even I would bring a speedlite to portraiture like that.

No faux HDR shadow-lifted nonsense will balance the background without sucking the color/soul/feel of that moment out of the shot. It's a parlour trick for that application.

A working photographer friend of mine had a whale of time finding a wedding photographer for his own wedding. He knew the time/location of the ceremony would be a bright blowout of a scene to shoot, so he asked prospective wedding photogs he was interviewing how they'd manage the background lighting. Some actually told him to not sweat it -- 'this camera has such latitude that I can just lift the shadows and rein in the highlights. You'll look great.'

He then crossed that photographer's name off of his list and called the next one. 8)
