Years ago I purchased my first off-brand speedlite but never took the time to learn how to use it much. Then I got the Canon 430EX and found how much more freedom it gave me to light a situation and add catchlights in my clients' eyes at outdoor locations. Even though I prefer to use a large reflector, I don't always have an assistant with me.
Finding that the 430 wasn't as powerful as I would like, I then got the Canon 580EXII speedlite and wow, it's a little powerhouse! I'm learning to use it on and off camera and how to bounce it off a wall or ceiling for more soft, diffused light. These skills will come in handy for upcoming weddings.
I just discovered photographer
Neil van Niekerk who gives you tips on how to use what he calls a "black foamie thing" and lots of other tips on how to use a speedlite. I also incorporate the
Gary Fong Lightsphere when there's no wall/ceiling to bounce off of. Check out wedding photographer
Melissa Jill who uses it. She's a fabulous photographer who's blog I've been reading for years. She's very generous in sharing her expertise with other photographers. I believe the post starts in August 2011, and you'll want to read all of them because they build on top of one another.
The other things I've bought in the last six months to help me fire my speedlites wirelessly is the
Paul C Buff CyberSyncs where you put the transmitter on your camera's hotshoe and attach the receiver (via a cable) on your speedlite or strobe lights. I attached some sticky velcro to my speedlites and strobes so it wouldn't just dangle. It allows you to take your speedlite off your camera, put it on a light stand, have an assistant hold it or whatever creative way you can think of. The PCB company is well known for their fantastic customer service and their prices are reasonable. The CyberSyncs do take batteries so that's the only limitation.
So last night I had the idea of taking a photo of one of our beautiful Bradford Pear trees that are in bloom right now with a speedlite either in the tree or behind it somehow so that it would shine through the white blossoms and illuminate the whole tree. It was a bit of a challenge getting my lens to focus so I used a flashlight to shine where I wanted the focus to be, locked the exposure and turned off the flashlight. I put the Canon 580EXII speedlite on it's included stand in ETTL mode and set it on the ground about 20 feet behind the tree. The whole time I kept pushing our cat Kovu away, but he insisted on hanging around and for the "winning" shot, he stepped into it! I love it!
