Photo 2 Lesson 6

Class #6
In this critique we broke into small groups and tool a look at the progression of shooting a single subject while changing technical variables such as aperture, shutter speed, focal length, etc.

Technical: Intro to Flash
We discussed:
  • What flash is, and why it has such a quick duration.
  • We found out what camera sync speeds are.
  • We showed how flash is not effected by shutter speed (other than sync issues).
  • We demonstrated how flash moderates it's output according to the aperture and the distance you are shooting at.
  • We discussed that while using shutter priority modes or manual how to mix their flash with the ambient light.
  • We discussed the difference between flash exp comp, and regular (ambient) exp comp.
  • We looked at how flash falls off because of it's distance from subject and size.
Creative: How to use flash effectively.
For this portion we discussed:
  • That using an on camera flash looks about the same as the pop up flash that is already on the camera (with a little more power).
  • To make better light we need to change the direction and the size of the light source.
  • We demonstrated how to bounce and modify flash.
  • We did a small demo on wireless flash.

Assignment #6

The purpose of this assignment is to get you to play with your flash. You will be trying to find situations that suit the following techniques:

Fill Flash: Try this one on a bright sunny day or with a light source that is directly above and/or slightly behind the subject. Take a shot using no flash at all. Then use your pop up (or on camera flash) and try the same shot again. Try a couple of variations with flash exposure compensation higher and lower as well as exposure compensation up and down.

Flash with a long exposure (slow shutter sync): Try this one in low light conditions where you can make shutter speeds of 1 sec or longer @ f/5.6. An evening street scene or city scape in the background (far from camera) with a person in the foreground (close to camera) would be a good situation to find. Take a shot of the subject with no flash (long exposure) and see what you get. Now try the shot with the flash on (in TTL), the camera in manual at f/5.6 at your camera's sync speed (1/125ish). Then try one more shot with the flash on and the long exposure to see what you get. *This can make results similar to the night portrait mode on your camera. A big key to successful looking shots is to have some sort of lights in the background.

Bounce Flash: (for those that have an on camera flash): For this technique find a subject (person or thing) that is near or can be placed near a wall. Try one shot without any flash at all if possible. See what you get. Then take one with your flash on, shooting straight at the subject. Then try to bounce the flash off the wall and see what you get. *To make sure your flash has enough power, take these shots around f/4 or f/5.6 at 400 or 800 ISO.

The more you do this the better results will get, so try to find several situations that may work. Make at least 4 4x6 prints of the best shots from the sessions to class 8. Have fun!

Some interesting links:
Strobist: Lighting 101 Try this one out. All about portable flash techniques. The first link is the the intro page. There is lots to look at on the sight.

Natural Looking Flash A wedding photographer Neil can Niekerk. He has some really good hints and tips on how to work with an on camera flash.

Remember that next weeks class is a field trip at the Legislative building. We will meet at the front entrance at 7:00pm.
Bring your Tripod or borrow one if you can, it will give you way more creative choice if you do. See you there!
