Amazon: did it come from Amazon directly or a third-party vendor that does business through Amazon? Also see the following note on B+H. B+H: I would definitely inquire about this. It's always ...

It could be the coating, purple is normal, green less so because that's where these coatings are supposed to be most transparent, assuming you're looking at it from the same angle as changing the ...

Yes, I was wondering why this article hasn't gotten more attention here, given that it's already over 1.5 years old.

For a camera as an image-generation system, one needs a sensor and a JPEG engine. Both need to be able to work with each other. While it might not be impossible to make an ISO 100 system ...

I understand what you're saying. You want a base ISO 100 system, and then use DR200 to get to a minimal ISO setting of 200, and so on. But that would work only if base amplification could be ...

Sure, but using the DR modes alone won't do it, which was my point.

That all depends on what the compensation does. The tone curves that are used with the DR modes put middle grey to where they should be given the ISO setting, ie in the same spot, otherwise they ...

This is a continuation of a discussion we had in the thread on Fuji's choice of base ISO of 200. Specifically, we were talking about midpoint calibration. Quite correct. However, during ...

Set ISO to 800 and DR to 100, 200, and 400 with identical aperture and exposure time. Examine raw values (e.g. using RawDigger). You will see that they that 1x, 0.5x, and 0.25x for that series. ...

The DR modes do not shift the midpoint

When there is a finite DR, one has to make a decision about how it is divided up into highlights and shadows; or, in other words, how to map the light from something that is middle grey in a scene ...

"So many"? How many are there really? And what are they comparing? IQ, mostly. What types of images? The ISO conundrum only shows up in some static images when people don't realize that they may ...

Personally, I wouldn't be surprised if middle grey went lower in the future. I think blowing highlights is a bigger problem for more people than are blocked shadows. Thus, devoting more of the ...

I'll try again. The system is basically a base-ISO 100 system. However, Fuji's auto-exposure system lowers the exposure by ~1EV (tag 'RawExposureBias', the correct value is 0.7EV), compared to the ...

Well said. You may have noticed that Bill did not reply here. I might be mistaken, but it sure looks like he is using the 'ignore' function regarding the particular individual in question. Be it as ...

I think it's been widely accepted that, within a generation, the performance of sensors with comparable technology is very similar. It is unwarranted to expect miracles without any strongly ...

I came to general photography through scientific applications of imaging. I did not deal with ISO, so nothing was engrained in me ;-) I always found ISO the strangest concept, because it is so ...

Well, that ISO setting is only truly useful for sooc-JPEG shooters. Raw shooters who take exposure into their own hands would indeed better be served by simply stating something that's more ...

Yes, ISO is a setting that relates to how the signal from the incoming photons is mapped to output sRGB values. But that only pertains to middle grey. There is much more to an image than middle ...
