well that's not good advice!![]()
Care to explain why shooting at ISO100 but underexposed by 2 stops is worse than shooting at ISO400 on a Nikon 800/600 series?
Numbers are useful here.
Try it.
This is how I shoot low light on my 30D.. I stop at ISO800.. here's the implied readout noise levels from the DxO data... on the D800 looks like ISO200 is worth having but benefit rapidly drops beyond that.
