The digital SLR course ended last week

Monday, September 1st, 2008 at 6:21 pm

Last Monday was the last week of the digital SLR course that I was doing with David. After covering long exposures we covered exposure, perspective, depth of field and (not) using the flash. From this I have added some more photos to the Flickr set.

These include the stereotypical flower for depth of field:

Small DOF (28mm 1/250s f/1.8)

double exposure using an external flash twice in a long exposure:

Long exposure - flash x 2

and using long exposure again, but with a moving sparkler and the external flash:

Long exposure - Sparklers and flash (1)

I would recommend the course to anyone.

  1. Great stuff Stephen. Would like to know more about how the latter two were produced.

  2. We were all lined up along one side of the room with our cameras on tripods set for bulb. Moses (the teacher) was on the other side (about 10 feet away) in front of the black cloth hanging on the wall. The lights were off and the blinds closed.

    As I was in the middle I was holding an older automatic flash, set for f/5.6 at 10 feet at ISO 100, above my head, aimed forwards.

    For the first photo Moses stood on the left for one firing of the flash, then stood on the right for another firing of the flash. All with us holding the shutter open.

    For the second photo Moses moved the sparkler around for a few seconds and then asked for the flash to be fired which lights him up shortly before the end of the shot.

  3. Stephen, I tried doing this type of thing over the weekend. I was unable to find a way to fire the built-in flash as the end of the exposure instead of the start. How was the flash triggered in your photos?

  4. The key thing is that the built-in flash was not used. The flash was external and there was no connection between it and the camera.

  5. Yes further research shows that it can’t be done with the built in flash as when you turn on rear curtain sync it fires twice. A proper canon flash can talk to the camera and ignore the first curtain. I’m thinking I might like a Canon 430EX E-TTL II Flash :-)
