    Why don't camera manufacturers just call it like it is...

    I don't need my 20d telling me that my camera is on a high ISO... just say 3200 just like it does when it's set on 1600...

    If I'm setting my ISO that high, I've already turned on a damn custom function. I know there's going to be noise, I don't need a stupid name for the mode.

    technically it isn't a true iso, it just works that its similar. especially with "iso 50" the contrast and tonal range is totally fucked

    unity gain iso for cropped sensors is around 1250, so anything above that you have posterization of the data values

    the "high" values are not achieved through sensor amplification but by manipulating the raw data.

    That being the case, would it be better to shoot iso 1600 when shooting manually then boost the exposure in post processing?

    It seems that a the horsepower of a computer might allow for better enhancement algorithms, or am I way off?

    you can underexpose it and then boost, but it'll be the same because you'll get more noise with an underexposure anyway.
