  • Thanks for the feedback. I’ll admit I’m not the best with technical details, my brain spaces out pretty quickly when I try to understand the finer points of the technology involved. As a photographer, I rely on instincts.

    There is obviously some need for technical understanding nonetheless, otherwise I’d be making lots of pointless mistakes. We are agreed on the practical implementation of the dual gain technology in modern sensors such as the one in my A9, which for me is mainly about preserving highlights; I am less likely to blow them if I limit my ISO to 800 vs. letting the camera bump it all the way to 6400 or 12800.

    I haven’t used Canon or Nikon, but the Sony mirrorless cameras I am familiar with are prone to overexposing the scene when it is mostly dark, but has occasional bright flashes (such as is the case at fire shows).

    I mitigate those tendencies by mainly relying on highlight metering, limiting my ISO range, and using S mode with significant (usually around -1 EV) exposure compensation when there are very bright flashes; that is usually enough for Sony mirrorless cameras to avoid blowing highlights (fire breathers are a notable exception, I have to key in everything manually in advance).

    As for exposure vs. light, you are correct of course. For good and for ill, “increasing exposure in post” is how I have learned to express my Lightroom editing process, since the slider I use for that is called Exposure and I increase that value.
