    I don’t have a 1D series camera, but I think the set up will be the same. You select HSS on the flash, not the camera. I have a Canon 430EX and the setting is selected on one of the buttons on the back. Potentially interesting aside,
    Canon recommend setting HSS and leaving it on as the flash will decide depending on camera settings and shooting conditions to switch between that and normal mode as required.

        My pleasure Harvey. I remember reading and re-reading my camera manual for how to set it before I worked it out!

            OK, my options would be

            1 Set the camera to the “P” setting and let the camera and flash sort exposure out from there. or
            2. Set the camera to shutter priority (Tv) and a suitable shutter speed (I normally select max for my camera, check your manual for what that is on your camera) or
            3. Set the camera to manual and select a shutter speed and aperture value. The flash will calculate a suitable output for the settings and light conditions. You can help the flash in certain circumstances by selecting lower shutter speeds or increasing or decreasing aperture settings.

            For all above, be aware of the maximum flash distance for your flash unit. This is where the other setting I have not mentioned so far can be useful - ISO. I usually keep my ISO setting at 200 or 400, but if I need to help the flash out in more difficult situations I can rack the ISO up a bit.

            There are a whole raft of other potential settings/options/preferences that could come into play, but these are the basics I tend to use. If you are new to flash photography there are many online tutorials and books you can use to learn the techniques.

              Don't think it matters what shutter speed your going to use it will work fine in high speed from 60th sec right up to your highest just remember it won't throw out as much light in high speed mode so you may have to add a bit of + Exposure compensation in your flash setting to compensate.

                I seem to recall that HS flash doesn't work in P mode.

                  High speed sync does work in P mode. Often the camera will simply close the aperture as much as possible before it starts to use faster shutter speeds.

                  If you have HSS set on a flash then the camera will use "regular" flash below the sync speed and switch to the HSS mode when the shutter speed goes above the sync speed.

                  So if you shoot wide aperture pictures outdoors in daylight then having HSS set allows the shutter speed in Av or P mode to be faster than the sync speed.
