Missing travel and on site photoshoot in far away places. Before that why don’t you practice at home first? The process is simple. Shoot the backdrop by underexposing it. If you want the background to be blurred, then shoot between f1.8 – f2.8. Taking note that the shutter speed do not go over 1/200 second as the flash is not fast enough to cover the whole body if the shutter speed is too fast (unless you have a flash system that has fast sync feature) Adjust the ISO and the flash power (M Mode) accordingly since shutter speed and aperture are fixed. Note: the shutter speed should be above 125 to make sure camera shake does not happen. Camera: Nikon D500 Lens: 50mm f1.4 Flash: SB800 naked and no softbox.
