Return 5D2 because of Low Iso Banding

You are joking right. It is a great thread. He hung you quite high :)
Not quite. He offered a lame apology for lying about "quotes" from me and others - which he had simply made up. Then, after essentially humiliating himself, he went away. Read the exchange if you are interested.

The thread finally dried up since he was the only one pushing the Noise Bander point of view with the usual sprinkling of personal insults towards those with other views, while several others tried to respond rationally to his insults and inventions and simply got flamed for their trouble.

If that's being "hung high," cool. :-)

I couldn't agree more with you.

Flame on me, hate me, I don't care. I am a college level Graphic Designer for nearly 15 years. What does that mean?!? It means I know how to use Photoshop and the tools. I've seen it all, from film to the first consumer digital camera files.

The 5D MKII is a great camera. I've never ONCE had a file I could not use in production, nor have I had a file that I've had to "push", within reason, keyword, in-reason, with bad results.

EVERY photo I see is user error in capturing and expecting too much or WAY too much expectations from post processing.

Does the 5dMKII band. Yes. But if you push the file to unreasonable expectations.

You get someone like John Sheehy or whatever his name is thinking the only result should be random noise, not a pattern. Whatever. I still haven't seen any photos from this "worthy" photographer. Troll to the extreme.

So also D3s is a bad camera as all canon (no a toy as 5D2) because his iso 6400 is a lot better than 200 pushed 5 stop!?
Do you prefer aD3x 100iso pushed 6 stop or a D3s at 6400?
Possible that for you the only important thing is the banding free in IQ!?

Details, sharpness, tonal range, color fedelty , amount of noise in shadows but also in midtones, high iso performance..all less important than banding to judge IQ?

What defines the boundary of "in-reason"? Results, or some platonic rule of 'exposure"? If the camera did not result in banding, and only fine, random noise, would it still be out-of-reason? Take a shot at ISO 800 on a 39MP Hasselblad. Is that not "in-reason"? Did you know that ISO 800 on the Hassy is actually ISO 50 under-exposed by 4 stops? The hardware has a single gain; ISO and exposure are just logistics. Take many of the Nikon, Sony, and Pentax DSLRs; or even the Canon G11. They give the same noise, shooting at ISO 100 and -3EC as they do at ISO 800, except the latter has 3 stops more headroom, and the RAW file is SMALLER . What is really "in-reason" here? The brightness of the review image, as the sole arbiter of reasonable exposure?

If it is not "in-reason" to underexpose the 5D2's ISO 100 by 3 stops, it is because IT IS AN INFERIOR CAMERA FOR DR , not because RAW data, in general, shouldn't be pushed 3 stops.
EVERY photo I see is user error in capturing and expecting too much or WAY too much expectations from post processing.
... from particular cameras with horrible shadows.
Does the 5dMKII band. Yes. But if you push the file to unreasonable expectations.
Every 5D2 image has banding. The question is, when do you see it. You see it when the contrast of the banding reaches a certain percentage of the contrast of the subject. Normally, you see it only in pushed shadows, but it could come up in very flat midtone and highlight areas, if saturation or contrast is boosted.

The fact is, you can push many other cameras several stops more than where the 5D2 starts to show banding, without seeing banding, just random noise, giving a slightly grainy look.
You get someone like John Sheehy or whatever his name is thinking the only result should be random noise, not a pattern. Whatever.
This is a huge distinction that you are trivializing. People like you have no idea what the DR potential is without pattern noise. For small images, a 5D2 sans banding would have 4 or 5 more stops of DR, even if it would only improve a couple of stops at 100% on a monitor.
I still haven't seen any photos from this "worthy" photographer.
What does your bizarre philosophy have to do with anything? I am discussing empirical realities of the RAW data. That does not require one to be a "worthy photographer" by your arbitrary definition. I'm not about to start picking out photos to show you, because of this challenge. You're just one in a long line of irrational people posting here.
Troll to the extreme.
A troll is a person who says things to elicit frantic reaction, as an end in itself. I have not displayed any such behavior here. Everything I've said is my real belief and am discussing the subjects with genuine interest in them. Calling me a troll is slanderous. Using the term troll to devalue everything you don't want to see here is juvenile.

So also D3s is a bad camera
Stop right there. This "bad camera" thing is yours. I do not paint cameras good or bad with a broad brush; that is not an intelligent endeavor.

Monolithic simplicity is for simple people, incapable of holding realistically complex ideas in their heads.
as all canon (no a toy as 5D2)
I did not say that the 5D2 is just a toy. I said that for low-ISO DR, it is a toy.
because his iso 6400 is a lot better than 200 pushed 5 stop!?
That's a problem too, because it means that a lot of the read noise at base ISO is downstream electronic noise, but it is a lot less than Canon downstream noise, with a lot less banding, so it is a better camera, in that regard.
Do you prefer aD3x 100iso pushed 6 stop or a D3s at 6400?
That depends on how much highlight headroom I want to allow. If the D3s doesn't clip the highlights, then I'd want it.
Possible that for you the only important thing is the banding free in IQ!?
No, that's not possible, but that is the squeakiest thing most obviously in need of oil, and only needing a drop of oil.
Detail, sharpness, tonal range, color fedelty , amount of noise in shadows but also in midtones, high iso performance..all less important than banding to judge IQ?
What is your problem? I am not talking about overall IQ, nor do I have to. I am talking about DR. Does the universe revolve around you and your monolithic simplicities?

Ah, true to form, John!

Given your scores of incessant and obsessive posts on this issue, the last sentence is superbly ironic, don't you think?

Using search engine on DPR found this thread.
Question, on your first photo, did you find banding when resolving the shadows
Some people were asking me how I managed to return my 5D2, because they always had problems with the retailers, since the retailers are reluctant to give your money back, even though it is your rights at some points.

Another work around is to chargeback using your credit card company. Your transaction was with the retailer, not with Canon (the retailer should deal with Canon).

If you are happy with your camera then move on,.. this thread is not for you.

But if you are not happy and wish to return the 5D2 camera, UK government supports you to return the camera. http://consumerdirect.gov.uk/

First you have to send formal complaint letter to the retailer using Sales of Goods Act 1979
Some formal letter templates are here:
http://consumerdirect.gov.uk/
http://www.google.co.uk/#hl=en&source=hp&q=sales+of+goods+act+1979&fp=1

Then you contact and send letter to your credit company
(if you bought your 5D2 with credit card).
using Section 75 Chargeback
http://www.moneysavingexpert.com/shopping/section75-protect-your-purchases

http://www.choose.net/money/guide/articles/credit-cards/section-75-of-the-consumer-credit-act-guide.html
http://www.google.co.uk/search?hl=en&rlz=1I7ADRA_en&q=chargeback+section+75

Keep your recorded delivery proof slip and all letters/documents and proof of purchase. The bank and retailer will ask for the copies of them. Don't send the original.

If everything fails you can go to Small Claim Court.

http://www.which.co.uk/advice/taking-a-dispute-to-the-small-claims-court/index.jsp

With the camera in your hand and all the test results and all of these forums on the net you can show the judge that the camera doesn't fit for purpose.

















I hope this helps anyone who needs it.

Wish you good luck.
 
I agree the 5D2 is a toy for those who do not know how to process correctly........otherwise it's a fantasic camera with fantastic IQ.

It's not a fantastic camera for DR. It is a poor camera for DR, by 2008 standards.

There is no way to "properly process" more DR into a single exposure.

Yes, I agree; what comes after your colon is BS. It's BS because regardless of whether you have a good point or not, your response is broad and sounds like a mantra; it has no specific solution, and doesn't show any indication that you understand what issues people are running into.

Your response sounds like nothing more than "I know how to process and you don't" bravado, because your scope is so narrow and you interpret things in the narrow context of your limited experience. I'm sure I know far more than you do about RAW data, and exposure, and processing. Most of the people who defend cameras with unnecessarily poor DR know very little about how things really work; they operate completely upon platonic ideals and myths, and biased, partial experience.

With right post production is possibile to obtain good quality also in DR and details also with the 5D2, comparable with all current dsrl.

Yes raw of 5D2 in shadows at low iso is poor and much less clean than that of Sony and nikon FF in term of bands but more "real raw" and details are all there.

I've finally taken the plunge to respond to these forums. There seems to be a lot of opinion rather than analytical fact. A quick search of google throws up the following two sites which describe the achievable DR of the sensor in various DSLR's along with the noise sources which are identified and quantified.

http://clarkvision.com/articles/evaluation-canon-1div/index.html

http://clarkvision.com/articles/digital.sensor.performance.summary/index.html

Well worth a read.

The absolute limits of the dynamic range are set by the sensor then compromised by the noise sources, A/D convertor (quantisation, dither) and the rest of the signal processing chain. The SNR(db) is not affected by amplification as the noise and signal are amplified by the same amount, assuming the number format supports the resulting value. ie changing the "ISO" or pushing values. Also the system transfer function will affect the perceived SNR eg by clipping low level pixels (article suggests Nikon's do this) or saturating at non-maximal input light levels.

Camera's can't capture the DR of the human eye but then neither can any of the output devices (printers, screens etc). Asking for more DR (subject to the noise floor of course) allows you to select part of that range for output or map(compress) between the input and output ranges (eg like HDR) .

(now opinion) To me structured noise suggests a process in the camera is creating this. Whether this is noise injected by the sensor readout structure and timing, power/clock etc coupling in to the A/D or some other mechanism I don't know.

It's a subjective view whether pushing images to expose this artifact is "bad" or whether you can see this in the output print and therefore not something I'm going to comment on. It's an individual matter whether it's important or not.

Does anyone have the statistical tools to analyse the raw images which are claimed to have banding to understand the structure and noise levels?
 
If returning your camera is what it takes to get you low iso banding nutjobs to move to a different forum, it couldn't happen any faster as far as I'm concerned, LOL. If you can't make a good image with a 5D2, you have no business owning one in the first place, so yes, please return it ASAP.

Who said that anyone complaining about the banding can't make a good image? The problem is that the 5D2 is worse than other DSLRs in the low-ISO shadows (and Canon is generally worse than other manufacturers, these days). Not only is there banding, but the random read noise is higher than most manufacturers except Olympus. Therefore, images which require more than 5 or 6 stops of DR can suffer on the 5D2, compared to other cameras and other manufacturers.

It's amazing how many whiners are on this forum, putting blame out there to cover their lack of skill with a camera and or processing. Especially when there are so many out there shooting amazing stuff. I guess the countless, and I mean literally countless awesome examples of 5D2 shots, with excellent DR, don't amount to anything to these nut jobs.

No; what's really amazing is how many people are so dim that they can't imagine why anyone would need more than 5 or 6 stops of DR in a single exposure.

Amazing stuff within a narrow range of requirements. Step just outside that range, and you get junk, junk you would not get on many other cameras, some costing 15% what the 5D2 costs..

You're not making any sense. I don't think you even know what DR is, because the 5D2 can not deliver excellent DR in a single exposure at low ISOs. Please define DR, as you understand it.

You probably don't apply any PP on your 5D2 files.

Because you and probably a few peopl don't use 5D2 for scene with 7 or 8 or more EV in DR.

5D2 is only a tool with can require more post production also for his "crude" raw.

Many here and in other forums are the amazing pictures captured with 5D2 and only 1 exposure with DR higher than 6EV.

Have you ever seen the gallery of gdanmitchell, Matt Anderson, etc?

Great pictures, many with much more than 6EV and captured with 5D2 (many with 1 exposure).
Is it si impossible for you?

One should obtain the better by a tool (the final result is important) and not to stop himself to find his limits.
