The flash diffusers such as the Stofen omni-bounce, Gary Fong Lightsphere and the like, are great little gadgets that can help create soft light in a small room, or a room with a low ceiling.

The fact is, these plastic devices that you attach to the end of your flash are not softening the light coming out of your flash.

Light itself is neither hard or soft. It’s photons flying through the air in a straight line. The only way to create softer shadows is to make the apparent size of the light source in relation to your subject larger. This can be done, for example with soft boxes and umbrellas placed near your subject. Another method, if you are indoors, is by bouncing the light up into the ceiling or into a wall, which will bounce back much larger light source than the small size of your on-camera flash.

You can also use these plastic flash diffusers to aid in softening the light indoors. What these attachments do, is send the light spraying out in all directions, which in turn, bounce off everything, causing light to fall upon your subject from many directions to produce the look of softer light.

Now, are you heading outside to shoot with on-camera flash? The first thing you should do is take your plastic diffuser off (if it’s attached), and shove it in your pocket, camera bag, or wherever else you feel like shoving it.

Contrary to popular belief, a piece of translucent plastic that scatters light in all directions without nearby surfaces to reflect the scattered light back into the scene, will not soften the light. A diffuser outdoors — a large majority of the time — simply wastes light, reduces range, slows recycle times and eats batteries.

The light that will hit your subject will be the light that starts at your flash and heads straight at your subject. All the other light spreading out in all other directions will not have anything to bounce back from and will just go to waste. If you think that bouncing off the clouds is worth a try, fahgettaboutit, that’s a lesson in futility.

Outdoors, use your on-camera flash as fill, and shoot direct. Your mileage may vary, but by setting your flash to ETTL mode with a FEC of -1 1/3 to -2, should yield some very nice results.

Most people when they think of using flash, think of indoors in low-light. Well, outside in bright sunshine, flash can be your friend as well.

How many times have you been outside taking pictures only to find all your subjects faces dark and the background beautifully exposed? Sure, you could adjust your exposure to expose the faces better, but now you’ll have a background that is blown out. A better solution is fill-flash.

Below is an example of a shot I took without flash and another taken just a few seconds later using flash.

I set my camera exposure manually to the scene (bright sun on a deck at 3:00p in the afternoon). This turned out to be f/11; ISO 100 at 1/250s. Because I was going to use flash, I did not want to set my shutter speed any faster than my camera’s sync-speed of 1/250. Another alternative would be to set your camera to shutter priority (Tv in Canon) and set it to 1/250 of a second. I prefer manual settings, for I don’t want the the camera being fooled by the scene.

My daughter was in her pool where the sunlight was coming from camera right, casting a shadow across her face. The shot on the left looks like a snapshot taken by anyone with a P&S. Just by using my flash, and setting it in ETTL mode (Canon) with a Flash Exposure Correction (FEC) of -1 2/3, that same shot brings out much more detail in her face without that harsh flash look. The sun still overpowers the flash, creating it’s normal shadows. I may have even been better off using at FEC of -2 or even less (in negative territory here), but now, the picture has a much better look and feel to it.

Imagine if the sun was coming from behind her. That first image would really show a dark face, which would be completely in the shadow. So, next time you are out in the sun taking pictures of family and friends, don’t be afraid to experiment with a bit of fill flash.

Happy Memorial Day to everyone. Today is a day to honor those who have fought and served our country and to grieve those who died while serving.

Memorial Day also signals the unofficial beginning of summer and what do kids want to do in the summer … SWIM! The weather in Bel Air today is fabulous — bright sunshine and 84 degrees.

While the kids were playing, I also was playing with my camera. I thought I try my hand at shooting with my right hand while holding a flash in my left. The downside to bright sunshine is the harsh shadows that accompany it. To bring out some definition in the shadows, a bit of fill flash does wonders.

The photo above — of my daughter Keely, the ham — used my technique of underexposing the camera 2/3 of a stop to cut down on the hot spots, and pop a bit of flash from the shadow side at 1/32 power.

The flash is not for inside use only. It can really come in handy outdoors as well. Give it a try, you may like the results.
