Thread: speedlite + ND filter on fast prime vs HSS speedlights

    Default speedlite + ND filter on fast prime vs HSS speedlights

    Hi sempais.

    Newbie question time.

    Which is more effective use of battery power?

    I am interested in controlling flash (over ambient) on a sunny day outdoors.

    Using Speedlights + ND-ed fast primes (eg ND filter on 50 1.4 wide open) or using High Speed Sync speedlights ?

    I am reasonably sure this question has not been asked before. (Search function due dilligence)

    However I am not even sure if I am asking the correct question.

    Any help is appreciated.

    Many thanks in advance

    A lot depends on the strength of the ambient light. How strong are you talking about?

    If it is very sunny, your speedlights might not even have enough power to overpower the sun

    Remember Nd or hss, the first thing to know is if your speedlight is strong enough to over power the sun. Most folks use strobes and ND. But even with strong sunny noon day sun, at 1.4 you will need a very powerful strobe and a high density nd

    HSS will use more battery, because it's a continuous burst of light over a period.

    Once you use HSS, your power output would drop by at least 2 stops. i.e both flashes might be at 1/1, but the HSS enabled flash will be like 1/4 power of the one without.

    Only use HSS when you need to shoot faster than 1/250 to freeze things. If the subject is not a fast moving subject and you are not required to freeze, you are better off using a ND (more efficient use of power).

    In the end I shot in the shade with toned down ambient (2 stops) as per strobist blog tutorial. I had a key coming in from camera right (porta soft box), and handheld a bare flash over the subject as a "kicker" (or what's the correct term?). No snoot, but i will build a grid soon from some Ikea straws. It should be interesting.

    I'm just a newbie... one of the little birdies is over exposed. Minimal Post done.

    C n C welcome.

    (I am using that soft wide open tammy 17-50 @ F10 or F8, with YN speedlites. )
