I am using the Nikon D3100 with an SB-400 speedlight and want to use an f/4 with a shutter speed faster than 1/200 outdoors to have the flash overpower the sun. I know the d3100 does not have HSS.Is there any workaround for this? I know I could close the aperture a little but I want a shallow depth of field.
