....
"As one example, the selection of a CFA, the color pattern put in front of the sensor, is a choice between quality of color, and ISO performance. If the CFA allows each pixel to see a broader spectrum of color (e.g. for the green pixels to see a bit further into yellow) a camera’s ISO range can be modestly increased. The resulting loss in color quality is subtle – subtle variations in color are missed and a handful of specific colors become difficult to photograph. In a market where a ISO 25,600 camera has a leg up on a ISO12,800 camera, the engineers are under enormous pressure to pick the modestly increased ISO over subtle color quality."

Thanks for the INFO. But that did NOT in any way answer my question. I suppose most people here are clear that High ISO means low DR When you split in three RGB Monochrome signals it is more than clear that with high ISO you get not so nice images.

And yet my question was related to: "colour that actually eye perception is UNABLE to differentiate?"

Can't wait to see sample images and sensitivity comparisons...

That's really interesting. A claimed advantage of medium format digital cameras have been that they have color-optimized CFAs rather than high ISO, it would be awesome if this sensor has taken the same type of optimization.

I think a 50 megapixel camera for sure should be optimized at high resolution use cases, rather than trying to be a hand-held low light action camera.
  Actually NO! The trend with MF is to optimize the ISO availability ;-)

A plea to the more knowledgeable people here:
Could you please enlighten me why Canon is going for colour that actually eye perception is UNABLE to differentiate? Or I misunderstood it?

Interesting. Could be one of the many reasons for the restared High MP competition:

However,  I suspect that the person referenced is just seeking to help defray the costs of managing a site and trying to cover the costs of one's time is not trivial for some of these sites. A few make a career of it (and when the quality of the content is of value, deserve compensation, e.g. this site or the digital picture.)
Even if that is the case - Hosting and similar Cost. Is there a backdoor for that? Otherwise if not officially stated the editorial of such a website/blog/vlog could be considered as pure hobby ergo all costs are not to be considered?

EOS Bodies / Re: Just for Jrista: 2014 Market Data
« on: January 29, 2015, 04:17:35 PM »
More than 45 days after the last topic post I am revisiting especially for our beloved Jrista in order to update it with some Canon Financial Results 2014 and two additional summaries.  First one & Second one

In short:

Results

Within the Imaging System Business Unit, although sales volume of interchangeable-lens digital cameras declined owing to the shrinking market—in Japan as a result of the reaction following the rush in demand prior to the consumption tax increase, and in Europe and other markets due to worsening economic conditions—the advanced-amateur-model EOS 7D Mark II achieved healthy growth, enabling Canon to maintain the market’s top share.

Outlook

As for the digital camera market, although projections indicate continued market contraction mainly for low-priced compact models, demand for interchangeable-lens digital cameras is expected to recover gradually.

And the most interesting part

As for the industrial equipment market, with manufacturers expected to continue making capital outlays for semiconductor lithography equipment in response to increasing demand for memory devices and image sensors, demand is expected to remain at the same level as the previous year. And as for FPD lithography equipment, demand is projected to increase as device manufacturers boost capital investment amid growing panel demand projected for 4K televisions and mobile devices. 

Would that mean update of the old 0.5 tech? As well as using the SONY systems or CANON own 5 layer CMOS? ;-)

2015 - good times!

EOS Bodies / Re: Sony Sensors Coming to Canon DSLRs? [CR1]
« on: January 29, 2015, 02:57:26 PM »
That means that they would have to use DIGIC CPUs sensors with DPAF (CANON sensor tech). That means they can't be SONY.

Considering that phase detect on the imaging sensor is something just about every manufacturer does that's quite a bold statement.
Phase detect - yes. DualPixel Auto Focus however as concept has been made by ONLY one vendor of 4/3 camera.... I believe it was Fujitsu... not sure about the name.

Maybe I'm just naive, but who makes RED's sensors, and why doesn't Canon go to them over Sony? The RED Dragon at roughly APS-H size beat out the full-frame Nikon d-810, according to ::cough:: dxomark.  Anyone know, does Sony make RED's sensors too?

The vendor is CMOSIS ;-)

I reckon that in a previous topic I've pinpointed exactly that problem:
...And I wonder how do you make a home-grown in-house tech go out to you competitors to produce it? Or you just don't - and that makes you look like everybody else.

If this turns out to be true - then it makes sense. Sony obtains DAF and Canon makes a big comeback.

Combine that with already high ISO capabilities achieved by both vendors and you get a better Noise levels thanks to downsampling, right? Or am I wrong about the noise?

There however still seems to be missing one part of the puzzle:
 
One shouldn't expect Dual Pixel sensors manufactured by Sony. No way.
So probably Canon will manufacture most of their FF bodies with own, home-manufactured  sensors and use only Sony sensor for a special high quality (DR, high resolution) body. That makes a lot of sense because high resolution Dual Pixel FF sensor (being effectively 2 x 46 MPix sensor) would generate enormous stream of data  that would need processing not only for stills but also video (scaling, denoising etc.) and AF (dual pixel, CDAF).
.... You said it all by yourself:

... would generate enormous stream of data  that would need processing not only for stills but also video...
That means that they would have to use DIGIC CPUs sensors with DPAF (CANON sensor tech). That means they can't be SONY.

Additionally where will be situated the the downstream amplifier(s) (secondary outside of the sensor amplifier - thanks Jrista for the clarification). If on the CMOS sensor DxO low-evaluation-of-CANON-sensors-trend will change drastically. AFAIK it is because of them CANON is always behind SONYKON.

I believe all amplifiers with SONY are on the CMOS and with CANON are not. How will they merge that logic. Complete change of logic on one or both of vendors' proprietary  DSP (digital signal processor). In Canon that means DIGIC 7S (s - for Sony sensors).

However, CR might decide not to allow begging on their forums.  ;)   I see lots of it on ebay.  One person was selling a scribbled note to raise money for a new 5D MK III.

Do you have a link - or it didn't happen.  ;D ;D ;D ;D

In some contest rules, I've read a pretty simple way to classify - at least for Americans.  If you list "Photographer" as your profession on you 1040 tax form, then you are a pro.
Actually that makes quite a lot of sense.

...But the truth is that clients that value results gravitate towards pros that can deliver, it is not about the gear (most of the time) it is about the consistency of the output.
I myself quite share the above quoted.

Depends what pro area of photography your are looking at and comparing it with enthusiast etc.
Seems like he is referring to stock and mass market subject imagery that anyone can get access to shoot.

For me there's no contest and I would not enter into any business area that there might be. I will deliver effortlessly and with style every time no matter what the brief is. Its not just about taking the pictures there's often the drama you have to create or sometimes minimise completely to make the job run how they would like.
Then turnaround the images the next day all processed really nicely.
Exactly the same here.

And that is why I do share in about 90% the opinion on how the Pro & Enthusiast are shaped. And though Thom DOES put the Enthusiast next to Amateur I tend to disagree.

IMO we do have the PRO that works for a bare existence and Tim Wallace among many other colleagues do shares the opinion that commercial photography is 80% business. However I believe that every PRO should be also an Enthusiast to some extend.

The market is oversaturated with generally the same pictures. More and more people on FaceBook already know how to make a descent portrait or a landscape. I hope there are enough people among you that DO recall how photos on FB used to look like. Then phones upgraded. DSLRs became more and more affordable. YouTube and many other tutorials were made and people learned HOW actually to make great photos.

So general PRO with boring same style is not a good idea for business. True - a PRO will deliver 100% a consistent output, but at some point that very same person has to become more of a Enthusiast in order to experiment. That can make him/her even a trend setter. A name-brand.

BTW it takes skill/talent to get good shots with an iPhone. And there are more than a few really excellent iPhotos around. You may have even seen some without realizing it.

I showed on many occasions that with an iPhone or an Android one can make photos that are impossible to be made with a DSLR with a huge LENS. Time will come soon. RAWs are already available on both platforms. Now we need I guess an iteration or two (five at most)  to get the DR (I do my HDR manually with PS after a nice bracketing) and faster and more sensitive focus.

Aside from size occasion-wise it is the same as in the article:
Quote
I’ve written before about any animal interaction in a National Park being more likely captured by an amateur than a pro. It’s a numbers game: there are more amateurs in the park with cameras than pros. And given the rise of smartphones, that has gotten incredibly worse, as basically a pro operating in public spaces trying to take unique images is now competing against everyone, not just other pros.

Photography is not what it used to be... And it is a little mess.

New clients sometimes believe they know what a nice photo is and ignore the consistency of the output that only a PRO can deliver without a risk. No matter if it rains or not.

I had a few such occasions. And I had to fix and finalize projects that were a few days away from the deadline. "Today" to deliver what some amateur had to deliver "yesterday". Or whose post production was awful or just disappeared...

Never underestimate the need of a versatile clientele ;-)
