  1. On-Camera Flash When and how to make it beneficial to your photographs

  2. Reduce your flash intensity • Many cameras will have a setting for flash intensity. Find it. This will essentially just turn down the brightness of your flash, which will avoid overexposing your subjects' faces. • You must be in Program, Aperture or Shutter speed priority or manual mode to change your flash power.

  4. Where to reduce flash intensity

  5. Make a diffuser • External flash units turn out better photos because they have bigger, better bulbs, mostly, but also because they're often fitted with a diffuser. These accessories soften your flash's harsh glow, but they're both expensive and generally impossible to fit onto your mom's point-and-shoot • A coffee filter held in front of a flash, a translucent film canister with a notch cut into it, a simple piece of A4 paper or even a piece of matte Scotch tape over the flash lens will measurably improve your drunk party photography.

  6. Activity • Pick an object or a person to be your subject. • Take your first picture of your subject with the flash set to 0. Your ISO should be 200. White balance should be?? (You figure it out) • Next take a picture with the following flash exp. compensation settings: 0, -1, -2, +1, +2 • Upload each to Photoshop. Put all of the photos into one document, side by side, and label each photo with the flash exp. Number it was set to. • Save as a jpg. • Turn into turn-in folder, with your name on it.

  7. Shooting in low light with a flash • In general, when shooting in low light conditions you have two options:1. Use a flash, which results in a well exposed foreground against an almost black background, or2. Use a slow shutter speed (ideally with a tripod), using ambient light to illuminate the background scene. • Slow sync flash, is a combination of both these techniques – using a slow shutter speed, with a burst of light from the flash – and results in a sharp subject, frozen by the flash, and a lighter background illuminated by the ambient light.

  8. Camera Settings • Many cameras have a setting called “Night Portrait” which makes use of slow sync flash, however I recommend setting it manually and reducing the flash power to gain more control and different creative results. • Select Shutter Priority on your camera, and then select a slower shutter speed. The actual shutter speed you use, will depend on the result you want. • If you merely want to illuminate the background, then select a shutter speed between 1/60th and 1/20th. However, if you want a more creative image with motion trails, then experiment with longer shutter speeds of 1/10th – 1/4th and longer.

  9. Flash Settings • Front curtain syncWith most cameras, the flash fires as the shutter opens, freezing the subject in the starting position, and creating motion trails until the shutter closes.Rear curtain syncSpecialized flash units allow you to set the flash to fire as the shutter closes, resulting in motion trails during the exposure, and a sharp subject frozen by the flash in the end position. • Set your flash power to between -1 and -2 (somewhat diffused to balance ambient light with well exposed foreground).

  12. Practice slow sync • 1. Pick a partner. In low light situations you will take a photo of your partner moving in some way. (spinning, head banging, moving hands or feet, etc) • 2. Set camera to auto and take a picture with the flash • 3. Turn off flash and take a picture on a slow shutter speed (set camera to TV or S and put the shutter speed to 1/60) • 4. Your mode should be set to TV (shutter priority) and your shutter should be set to 1/60th and 1/20th of a second. Make sure you flash power is set between -1 and -2. • **You need to stay in class to practice if you are not passing the class**********
