For a while after I first got into lighting, it was all about soft light, the softer the better. We’re talking massive softboxes as close to the subject as I could get them. It’s a beautiful way to light, but more and more I find I want my images to have some grit, some character. Enter hard lights.

I try not to call her "Hard Lights" to her face
The problem with using hard light is, well, it’s hard. By hard I don’t necessarily mean harsh; I mean the transition from light to shadow is very quick, or non-existent. This can give you problems if you want any detail in those shadows, because they’re going to be pretty much black, unless you use some kind of fill. Enter the sun.
The sun can be a harsh mistress, it’s true, but if you know what you’re about you can make some really stellar images in even the harshest light of the day.
Pardon me a moment while a go into a little in-depth aside about lighting. I think the biggest mistake people make about lighting a subject is to think that it is about removing shadows. It’s actually the opposite, it’s about creating them, but putting them exactly where you want them and being in full control. That’s why on-camera flash looks terrible, it destroys all those shadows that give your subject it’s depth and three-dimensionality.
So how do you create shadows in harsh sunlight? Easy. You overpower the sun. Believe it or not, but usually you can do this with a single bare hot shoe flash, so long as it is in close enough and on full power. Easier still, stick a couple of flashes side-by-side, and get the choice between more light, or a lower power setting for a faster recycle time. Worried about casting multiple shadows? Stick the lights behind a small umbrella and now they’re one source, or else gaffer tape them together so they’re so close they might as well be one big super flash.
Stick the sun behind your subject, and maybe slightly to the side. Depending on the angle, this can give you a nice rim light, and you wont have to worry about the sun being in the persons face (squinty eyes generally don’t leave people looking their best). Stick your flash on the other side of your subject, facing back towards the sun, put it up nice and high, and point it down right into their face. This is a very good opportunity to not be a total dick. Do not tell them to look at the flash. That’s bad juju. Or, if you really want them looking into the light, have them wear glasses. Mirrored shades tend to look completely bad ass when shooting in harsh sun.

As for exposure, you have two choices: a neutral density filter and a wider aperture, or a really stopped down aperture. The only thing to consider with this choice is how much depth of field do you want? Once that’s decided, underexpose the background a tad. That’ll leave your sky a nice rich blue, and really put some drama into everything, especially clouds if there are any.
Sound like a lot? Sound intimidating? Try it, I dare you. I guarantee you fifteen minutes of futzing around with camera and flash settings, and you’ll end up taking one of the coolest photos of your life.
