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?

With that in mind, if I shoot in a studio setting, is keeping the ISO low still preferable?

If you’re shooting in a studio setting i don’t see how you would need higher than 100 iso , since sub 200th of a second is the normal flash sync, you’d have to go to like f22 to start overpowering your lights.

I understand that very well. My question is that, does Base ISO on your camera signify the cleanest image in all settings?

Yes, base or native ISO will produce the least noise in a correctly exposed image.
