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?
If you can’t get the shot without high ISO, then use high ISO. Programs are getting better every day to deal with the noise as well as the cameras.
Would you rather have that shot of a lifetime with some noise or miss it because your ISO is too?
