  • The target image brightness is governed by four major factors: (1) scene luminance: how much light the scene is throwing at the camera
  • Lower base ISO means that either the system as a whole or the sensor itself has lower sensitivity. So, one could put in a crappier sensor, crappier CFA and/or crappier microlenses. Not likely. One ...
  • I think a few things are mixed up here. ETTR and stacking aren't alternatives or opposites. ETTR simply means that one is trying to get as much light into the camera as possible. The more light ...
  • I haven't read through all the responses here. But if you're asking such a general question about CFAs and sensors in general, it is probably best if you simply judge the output of the candidate ...
  • I do not know anything about Sequator, but a general problem with this type of superposition is that there are both static and moving parts in your scene. You could crop the trees out of your ...
  • It's 'scientific' alright: you did an experiment, made observations, collected data, analyzed the data, and drew conclusions. The only problem is that it's bad science as the conclusions drawn are ...
  • Replied in ISO v EV
    Actually, I like the water/bucket analogy. It has its problems, like any other analogy, but it's suitable for illustrating a lot of concepts. I would include the scene that shoots water with a ...
  • Replied in ISO v EV
    Old school is so, um, dated.  think there are fundamental differences between film cameras and digital cameras that warrant different approaches, particularly when it comes to ISO. You're basically ...
  • Replied in ISO v EV
    Yes, I do think it was a deliberate decision. I don't think Fuji was lacking intelligence when they did that. And I think they are reversing their stance because it's an often-requested feature. ...
  • Replied in ISO v EV
    Take a deep breath and read calmly what I wrote. I wrote that "it doesn't seem it was a bug but a deliberate decision". Of course I have no proof, and neither do you that it wasn't a deliberate ...
  • Replied in ISO v EV
    You have been participating in these threads yourself, and not everyone agreed that it's an anomaly, first of all Fuji, because it doesn't seem it was a bug but a deliberate decision, even if they ...
  • That can happen. But we're talking about a stack here, so SNR should be quite high, which will alleviate the color-shift issues. Besides, incidentally, one big argument in the past for doing ETTR ...
  • Replied in ISO v EV
    When setting aperture and exposure time explicitly, on my X-E1, the EC dial doesn't do anything. This is a matter debate around here occasionally, where some say, the EC dial should change Iso ...
  • You can use the stacking method in general for all kinds of static low-light scenes, e.g., in churches or museums that don't allow flash, or at night to get a high-SNR image of a cityscape. Of ...
  • I use Op/Tech . They have a modular system that allows the camera to go from sling to neck strap to the front of a backpack in seconds.
  • The idea of stacking is to take many images to build up SNR. It's a way to get higher exposure without running into camera limitations. Increasing ISO will not do much, if anything, for SNR, only ...
  • They probably cheat somehow :-D Also, ETTR at ISO6400 is pretty difficult. ETTR is usually done at base ISO. Anyway, you're already at 20-25s exposure time, so there doesn't see to be much you can ...
  • Yes, you are correct. BTW, I just love how you typically respond to such situations by shouting "YOU ARE WRONG!!! YOU DON'T UNDERSTAND!!!". Nice style. Never considering that there might have been ...
  • EC changes ISO only when minimum shutter speed is exceeded. That is a special case that I did not want to go into at this point; neither how DR settings affect the whole thing.
  • Replied in ISO v EV
    There have been some good responses so far, but there is inconsistency as to the terminology used, so I would expect it all to be a bit confusing. First off, I assume with "EV button" you actually ...
