A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

Can someone explain how ISO/Base ISO functions these days? (alien.top)

So generally, I’ve always understood that the lowest ISO is best to shoot at. Though with newer cameras, they usually have a higher base ISO and in some cases Dual ISO.

I usually work with the R5C, even for photography. It feels odd to take portraits at 800 ISO because I’ve always been told it should be as low as possible.

So does the Base ISO system, negate the need to shoot at lowest ISO for the clearest and least grainy image?

The dual ISO is for video in order to capture maximum dynamic range when using LOG profiles. It’s got little to no relevance for stills photography, unless you’re shooting stills in log. Max DR for stills is usually at 100, with the R5 sensor it’s 50 according to our friends at DxO.
