To be honest its was another togs words of advice to me. He is a super successful photographer so i took his word as gospel.
Not saying its right just waht i shoot for landscape.
But surely if you have everything in focus at F11 then that is going to be better than F16 isn't. Other than creating star burst or wanting a slightly longer shutter speed without the benefit of ND filters shooting at F16 would just be pointless compared to F11 or F9 etc (this is pending everything is in focus at F11). Once something is sharp and in focus then it can't be more in focus...
True, but if you have very close FG and a far mountain, F11 will not give the DoF you need. If everything if is can be in focus at F11, then thats's to use, if you need F16 to get the depth, thats what to use.
I use as wide an aperature as possible to get all in focus, but F11 sometimes is too wide.
For my Olympus it is ISO200 to get best dynamic range.Your optimum ISO will depend on the body, my 5D3 it is 100 whereas my digital back is 25, some Nikons won't go as low as 100 for example.
