Flashes are designed to do just what their name suggests, “flash”. This operation is different from a studio strobe because flashes do not light as lamps before firing. Flashes are smaller when compared in size to studio strobes and much more portable.
Flashes are a quick and easy way to add light to a photo without requiring a full light set-up and accessories like reflecting umbrellas. Just to be clear a flash is no substitute for the full lighting set-up.
I have so long kept back from writing about strobe, flashes and every other studio light because it is very easy to think “If a little light is good, then more is better!” or “This shot isn’t quite right because of this dark spot, it must need more light.” These assumptions are not always true.
Up to this point I also have not defined the venue of the photography. Many portraits these days are shot outdoors. Yes a good number are shot in a professional in-door studio, but just because more or less are shot in one place over another means absolutely nothing when it comes to doing your best job with each portrait. As I write this article, I have an outdoor setting in mind with some great texture variations and color fusion. Something like your nearest botanical garden.
Never hesitate to use the light already in your setting. The more natural the lighting looks will enable you to focus on your subject’s personality and facial expressions.
I understand there is a lot to think about when taking photos, believe me, I do not work like some photography super hero. We will get better, faster and smoother the more we practice the right techniques and processes.
Having your subject looking into the sun can be hard to do for a while, so offer for them to turn their back or side to the sun and fill your shot with a flash. Perhaps even getting the hard shots over first and then just dealing with the flash in the rest of the shoot will not be as difficult.
Always being considerate to the subject so that looking any one direction is not kept up too long, find a routine that works well for you and use it!
