As a baseline, I shot these yesterday. The DOF [Depth of Field] is shallow. My next shoot, I will use manual settings. Anthony Martin [a colleague] says:
Set ISO to 400 or even 800 (best to go to 100 if you can). Set your aperture to a small value (I use f/11 unless I am going for creative and not working at 1:1) . Use the lowest shutter speed you can handle (probably 1/100 or less).
