Yes, the intensity is captured but the spatial data are missing, just averaged out to one value.

But he is right. There is only 1/4 of pixels, i.e, half the resolution in both directions.

Sorry, but no, it was not. There was a slight improvement. I work with an sd Quattro H and I see problems like this in many pictures. And I used an SD1 since it was released, so I know what I am ...

You know that this is ISO800?

I checked the pictures on his web page and they are quite good, i.e. beautiful. But looking at them in 1:1 presentation reveals the Quattro problem. It is very obvious. Here are two screenshots (100%).

I see it the same way. There are positive things to say about the design and handling of the Sigma cameras. I know, people have different oppions about it, but I really like the Bauhaus kind of ...

As you say, it improves a little bit but this improvement is not worth the time one has to invest. Interestingly, the image falls apart after the adjustments you did in RawTherapy. The TuFuse ...

Thank you for the explanation, makes sense to me. Still, even after steeping-up the contrast curve, insn't the maximum DR given by fully transparency/max. density? That means, the slide may have ...

Isn't that the other way round? (note: I added the text in bold to give the complete context after snipping away most of the text). Negatives have a max. DR of 12 (density 3.6) and slides are ...

Whatever! I responded to the question by Rick if the 40mm lens will be 3600 USD or Yen.

I think this is the price for the camera. One source says it will be $4500 and the other says $3600. The second source mentions a new 40mm lens but I assume the price is meant for the body.

Your answer is patronizing and you simply got it wrong. Of course, the ADC has a given bit depth. What I wrote is that doubling the sensor output doubles the ADC value. „thus adding one bit“ meant ...

I read this here not for the first time. And it is wrong in the context we discuss. The sensor to ADC path is linear and 1:1, i.e. a doubling of the signal from the sensor results in a doubling of ...

Is there a reliable source for the information about the number of ADCs in a Foveon design? I never heard of it. ENOB < specified bits is well known and holds for every ADC in any camera. So, at ...

You know that for most cameras ISO is just a mimikry of film sensitivity and a simple mathematical multiplication of the sensor data. So, any ISO setting is possible and I don't see any difference ...

Don‘t apologize. The humour was very obvious. Unbelievable that it was mistaken as a real camera comparison......

Not necessary to reshot the pictures. The DC crop mode simply cuts away the outer pixels. Nothing is changed in the analysis of the results, IQ is exactly the same. As you say, just larger files.

Isn‘t that a drastic difference? Unless you look at the pictures in such a way that they fill a normal screen, respectively. This way, the hi-rez picture can‘t show the higher resolution. Once you ...

These are two shots. Seems that the AF changed focus. Right?

Licht means light in German.
