Fair game. However, all you've done is proven that a camera that is not DR limited won't have shadow problems. Of course it won't. .

So just to be clear, you are saying that the example posted by PBD ( which was shot into a clear sunlit sky and attempting to hold good data in the deepest recess of the mandatory DR testing awning ) was not a great enough EV range to cause the Canon sensor to have DR issues ?

I wonder if Canon have sold them the rights/tooling for this lens because Canon are about to introduce a new one, which will be much more expensive of course.

Buy whatever gear that fit their needs and move on. I heard enough about people keep telling they going to switch to Nikon and Sony for the better, still, none have done so.

Talk is cheap, be a man and do it.

Yup, talk is cheap:

...

I don't ever just buy before I give it a real good try. But I'm not just a bag full of words, either. :P I intend to get a solid handle on the state of Sony raw files (and the full range of the consequences of their lossy compression) before I bite the bullet, but even if I can't work the data like I can with a Nikon RAW, it should still be worlds better than Canon data.
Hi,
    Renting also not cheap... :o

    Anyway, I try out the A7R and A7S with metalbones, A7R focusing is really slow in low light and I don't like the heavy shutter... the A7s had better shutter feel and AF in low light is faster, but still not very consistent.

    Enjoy the camera...  ;D

    Have a nice day.

Yeah, I've heard about the shutter shock problem. Part of the reason I'm renting first. It's not all that bad, considering its some $2400 to buy the camera lone, let alone the adapter.

I'll try the A7s at some point, or whatever new cameras Sony releases next year. I particularly want to get a handle on the raw IQ, and the impact of compression. I want my RAW to be RAW...and I don't like the use of lossy compression for "raw" data. I'm hoping it isn't a huge deal, but I guess we'll see.

Looking forward to seeing what you are going to post from the Sony. ( No sarcasm). Remember to include some shots with single exposures and challenging lighting akin to those that you have linked to in the past from 500px. (Well OK, maybe a little bit if sarcasm there).

This is getting quite surreal and ridiculous at the same time. Pushing exposure 4 to 6 stops. That's pure madness :) (meant in a good way).

Your not alone in thinking that. Once those missionaries that preach Exmor start talking about pushing six stops I think we can all relax in our heathen ways.

When I can snap straight into the sun and produce this image from one exposure with the Canon, who gives a damn ? I know I don't. The push/pull in this was about 2 stops.

my son, born 9/24/14..no PP, jpeg export via 6d wifi.  which is a PIA....  canon does need to make that process easier....but why am i saying that...i am a dad...say hello to lucas!!!!!

Congratulations Chuck ! Let the expense begin !  ;)

Lovely shot , jpegs are definitely getting better off the latest cameras.

Just a question on the 6D. As a wedding photographer how do you cope with the flash compensation set up on the 6D compared with the 5D ?

Site Information / Re: Canon Rumors Site & iOS 8 Issues
« on: September 24, 2014, 05:28:16 PM »
iOS 8 has a ton of bugs. I have been using it for most of the summer through my Developer Account. There were actually very few betas for this release...makes me wonder if they wanted to just get it out in time for the new phones.

Either way, Wifi is slow or doesn't connect, apps crash like crazy, and battery performance is a mess. Location Services keeps running in the background for system services too, which is strange.

iOS 8.0.1 which was released today is a mess too. The over-the-air update through the phone or iPad system preferences caused the devices to drop cellular reception and Touch ID capabilities.

Is there any way of re loading the previous iOS ?

Yes, there's three ways of fixing the issue:

1) I believe Apple is still pushing iOS 8.0.0 through iTunes. So, if you've updated to the newest version through Over The Air, then you can connect to your phone and have it restored to the old version.

2) You can manually download the 8.0.1 IPSW file from another source online. Check www.MacRumors.com in the iPhone forums for download links.

3) Similar to step 2. Find an iOS 7 IPSW file and restore through iTunes using the Option + Restore method.

Many thanks for info.

If this turns into an Apple bashing or fanboi lynching...........blurgh

I'm definitely getting less DR since installing iOS 8 .........

I've "upgraded" my ipad 4 to iOS 8 and it's made a right mess of everything. I strongly advise anyone with an ipad to leave iOS 8 well alone for the time being.

That's not an entirely fair comparison.  The entire Canon shot starts out darker before processing, and ends up brighter after processing.  So you're obviously giving the Canon shot more of an exposure boost in processing. 

With such a heavy shadow boost, I seems you are trying to create an "HDR look" without actually using HDR (combining different exposures).  That's valuable if you really want or need to substitute one technique for another, i.e. boosting shadows instead of combining exposures.

The Nikon/Sony sensor certainly has an advantage if you really need to do this:  shoot a high contrast static scene with maximum shadow detail but without using any of the techniques that photographers have used for such scenes in the past, such as blending bracketed exposures, adding light, choosing a time of day with less contrast, etc.  That sensor advantage matters to some photographers, but not to others.  I understand it's important enough to some to make a switch.  At the same time, it's not evidence of a flaw in Canon's sensors, which perform quite well for photographers who don't need to do what you've shown.

He's not trying to create a HDR look without doing HDR. He's trying to map the real world brightnesses of those objects into the compressed space of the L(ow) DR device that is your monitor. This is known as tone-mapping. And when your sensor is as clean as Exmor is, you don't need HDR. HDR was 'invented' to overcome the shortcomings of noisy sensors (and film, you could say). It's not some 'standard technique' everyone should use. It is and was a crutch for less-advanced technology. Once you have sensors with no noise, and with full-well capacities (FWC) so high that even shot noise is mitigated (b/c you're just sampling so many photons), there won't even be a need for HDR. Ever. The D800 got rid of most of the noise, and the D810 took us one step closer to this by extending the FWC. It's only a matter of time. Meanwhile, Canon's FWC and read noise are stuck where they were more than 6 years ago. And that's fine; they're prioritizing other things. Maybe they'll catch up, maybe they won't. But that doesn't change the creative opportunities that noise-free technology in almost every other brand affords, and there's no point in arguing against that. You might not need it, but many do, and many more don't even know they'd benefit from it.

What was that Steve Jobs quote again? 'People don't know what they want until you show it to them.'

In the future, with HDR displays, you won't even need to do any of this tone-mapping. You'll see those Exmor shadows b/c the white point will be extended and the entire brightness scale will be shifted (towards brighter). The shadows will automatically become more visible b/c they're brighter on your monitor. You won't need to do as much tonemapping, and so the 'HDR-look' will be mitigated.

And if you're looking at old Canon files on those sorts of devices (which already exist), you'll be looking at noise even before you raise the shadows.

If he's not trying to create an HDR look, then why does the processed version have such an HDR look?  That's not a real world look.  That's one interpretation of a real world look.

It's great that you've found a sensor that meets your particular photographic needs.  That's great!  At the same time, meeting your particular needs is not the definition of a "good sensor" or of "creative opportunities".

Further, it's rather odd that having moved on to Nikon, you would spend so much effort on a Canon forum demonstrating how a Nikon sensor meets your particular needs.  Photographers can easily pick out unique advantages in *each* system, and demonstrate how they meet some specific needs. 

Odd or not, his feedback was and continues to be rather useful, at least to me. This coming from a long time Canon user (AE-1).

It's puzzling how users of this board take sometimes constructive criticism as an affront.

Quote
For example, now that the 7D Mark II has been introduced, should I go over to Nikon forums with posts demonstrating how this camera has a unique anti-flicker feature that helps sports photographers who shoot action in fluorescent light? Should I post examples of clean 7DII shots vs. "less advanced technology" Nikon shots that show awful exposure and white balance shifts from shot to shot and even within a shot?

If it's within context and in a civic manner, why on Earth shouldn't you?

Quote
Or should I go to Nikon forums to demonstrate other advantages of the Canon system (flash features, specific lenses, dual pixel AF for video, etc.), all the while mocking Nikon users for not "understanding" these Canon products and the "creative opportunities" they are missing?
  Short answer:  no.

If you're mocking whomever, that wouldn't be very helpful towards your arguments now would it?
I didn't find anything offensive in sarangiman's posts, on the contrary, i find them informative and surprisingly calm, considering the fact that pointing Canon's shortcomings is such an anathema here.

Agreed it's not the 'look' I would go for, but I have to say the data from the lifted second image, the Exmor, is superb and I can't really see why anyone would want more than this. Makes me wonder how sensors are going to improve upon this in the future.

As I've always said, if you want to lift data by this amount the Exmor is substantially better. ( Though if you were comparing your 1DsIII the latest Canons are better).

However I never do so for myself it's not an issue.

I'm talking about normalized Raw performance, which has seen very, very small gains. Save for at the highest ISOs (e.g. 25.6k and above), where lowering sensor-level (upstream) read noise actually affects image quality, since you're amplifying the raw signal off the sensor so much (b/c the signal is so, so small).

Otherwise, ISO performance is largely dictated by sensor size these days.

If you are referring to low ISO I wouldn't agree. The 5DII had substantially more latitude that's the original 5D at the highlight end, even if the actually DR wasn't greatly different. Likewise the mkIII has substantially more latitude than the II, and the 6D a tad more again. Tonal graduation has also improved, as well as highlight headroom in terms of clipping to white, as well as at the other end in graduation to black.

OK so this might only be noticeable to the discerning user.

I can appreciate that, but that doesn't mean you are not compromising by using it at f/1.4. Knowing what those compromises is important.
Your example is poor, perhaps if you had started with a different lens in a different situation you could demonstrate your point.

I knew of that compromise. What is hard to predict ahead of time - you know me not being a computer and all - is exactly where I'd run into the noise floor.

And that's what's so nice about Exmor - you don't have to worry about that. You can worry about other things, like focus, or capturing the decisive moment.

My example is not poor, it's just irrelevant to you. I've posted examples of other use-cases, and gotten answers like 'well I don't shoot that high DR scene', or 'you could've just used a GND', or 'oh you already used a GND? well you could've HDR'd it then'...

My point here is that you can always have an answer as to how you could've done it differently.

Doesn't detract from the main point: this is one less thing I have to worry about now.

These same arguments are constantly recycled. The same sentiments were thrown around during the digital vs. film debate.

As for sharing the whole file - no point. I did years ago when I showed this same problem with fixing vignetting with the 24/1.4 on my then newly acquired 5D3. And it was the same thing. Some people got it and agreed it was unfortunate, others said I should've used a flash or just accepted the vignetting, etc. And all those comments still missed the main point - I wanted available light only for that shot, and I generally don't mind vignetting but for that particular shot I didn't care for it. But I didn't have the choice to take out the vignetting, b/c of the ugly banding that ensued.

There's really no point - I just saw jrista arguing thread after thread about how he'd like to simplify his workflow by not having to resort to HDR every single time. It's the same argument here - I'd like to not be so constrained by my system when there are better options out there.

I didn't consider Nikon to be a better option until enough factors swayed me. Like not designing the grip for elf hands, for example (that ones for you, jrista).

You can certainly talk the talk, but after all this typing and in put from others I don't see this can continue until you post the full, original image as many of us have requested. Mask the faces if necessary as suggested by PBD. You've made all sorts of allegations against the 5DIII not coping with the situation: let's see the full picture.

Always interesting to hear from people who have real, practical experience with the different systems, rather than those who fantasise over what they think a different system can do to improve their photography.

I must admit I'm a bit of a Fuji fan myself, but having learnt over the years that multiple systems are, to me, a distraction from making real images, I now religiously just stick to one, other than trying out the opposition now and again to keep myself up to date.

Oh, and here's yet another wedding image I was processing from my 5D3 that I decided to throw out b/c by the time I corrected the 3EV vignetting of my 24/1.4 and then added 1.5 stops (b/c I underexposed by 1.5 EV to save the sky/clouds above my subjects), I had this wonder junk overlaid over my image

Maybe you should learn to convert and process your files properly.

I always thought wedding photographers make use of reflectors to avoid such classic lighting problems? That was what my wedding photographer did to get a beautifully exposed shot with the sunburst and blue sky behind us. Oh, he was using the Canon 5D classic.

Oh, here is another example: http://www.mattgranger.com/light. Matt has mostly Nikon gear.  ;)

You are absolutely right, except that generally those here suggesting the Exmor tech can do a better job don't want to be bothered with fill, they want to be able to use every ounce of the extensive latitude in the Nikon file.

They will of course will be lifting data that has recorded virtually no light, so the photographer using 'old' tech such as a 5D or D200 and sound technique will produce a much higher quality image.

So what happens if you use sound technique with both Canon and Nikon ? You get pretty much the same image. A well lit and correctly exposed image will always triumph over the same one which has been poorly lit and under exposed.
