This week's challenge was Motion and I decided to experiment with Rear Curtain Flash Sync to create a feeling of movement in my images.
Without getting overly technical, there are two 'curtains' in your camera which are triggered when you press the shutter button to take a photo. The first (front) curtain slides up and exposes the sensor (or film, which is what I used 'back in the day') and the second (rear) curtain follows behind, protecting the sensor from over-exposure. Once the second curtain has finished its movement, both curtains return to their original position. The delay between the first and second curtain movements is what's called 'shutter speed' and is determined by the setting you dial in.
Using a long exposure (also known as a slow shutter speed) causes the subject to blur or streak, depending on how quickly it's moving. If you use a flash and set your camera to Rear Curtain Sync, it causes the flash to give its pop of light right before the second curtain starts its initial movement.
So why do we even care about this? Because instead of simply having a streaky subject, we can also freeze its movement at the end of the exposure, giving a more solid object for the viewer. It shows us the subject as well as its path through the image.
I also moved the camera to streak the background and give an even greater feeling of motion. Horse popped up to see what was going on, so I turned my camera on him too. That's just the way things roll around here.
