Online Advanced Assignment- Slow or Rear Sync Flash

  • Jun 30, 2013 · 7:00 PM

This is a fun subject. By using slow or rear synced flash, the shutter remains open capturing all the available light. Then at the end, the flash pops freezing the action. This is handy for those images where you want to show movement and time. By popping the flash at the front, the movement trail and the stopped action will be reversed. So a car for example, to front flash a moving car over a 5 second exposure will result in a still car with a trail happening in front of the car. using rear sync, the flash pops at the end of the shutter, putting the light trail behind the car. Play around with the different flash settings- slow sync, rear sync, front flash, high speed flash, and maybe even multiple flashes in one image. Different cameras use different names for these same techniques. Search the web or read you manual to see which one applies to your camera.
Submit one image, change to web size- 640 on the long, at 72 dpi, JPEG. Please make a new image for this assignment. No archive digging.

    I had no idea this was a feature. Thank you for bringing this to our attention. I'm excited to try out some techniques with this. On the Canon T3I (and I'll assume other similar Canons as well), it's First Menu > Flash Control > Built in Flash Settings > Shutter Sync, it's called "Second Curtain".

      It can also be activated on the external flash units. On the Canon it looks like three triangles, two faded out, the third filled in solid. I'm sure it's possible on Nikon and other main stream cameras.

      Mark, thanks for the tip. You just saved me a big chunk of time I'm sure.
