They were not mine. The best I came up with in the admittedly limited time I devoted to the exercise was this.
Pffft. As the kids' episode of Phineas and Ferb came to an end, so did my light painting.
Instead, we did this.
I think the Expert Photography guy would classify this as light graffiti, so I might just give myself a free pass on day 26.
To my kids, this is light saber photography. You achieve it by having your light saber fight with flashlights in the dark at a long exposure (very slow shutter speed).
I highly recommend this as a way to entertain your kids. We went to our basement on a dark, rainy day, and I covered the one basement window. I set my ISO to 400 and my aperture to f/5.6, then put the camera on a tripod. I used a remote, but that really isn't necessary if your subjects will be moving--you won't keep them in focus anyway, so there's not much need to avoid camera shake.
Most of these photos were taken with a shutter speed of 5 or 10 seconds (5" or 10" on your camera). If we used a longer exposure, the flashlights illuminated the whole scene.
In post-processing, I darkened the blacks in these photos to further reduce the illumination created by the bright flashlights. Next time we do this, I would like to try with pen lights that don't shine so brightly.
To get the pink light saber, my daughter held a piece of pink tissue paper over her flashlight.
I realized too late that I should have had them remove their white socks.
When trying the cartwheel trick, my son had the next brainstorm. He took off his socks, put a flashlight in each, then used the sock to swing the flashlight in patterns.
My daughter ran and swung a flashlight sock in this one. I think it looks like the flight of a spastic firefly.
For me, light painting was a bust. Light sabers, however, were a huge hit and created some beautiful patterns. Next time your kids are bored, grab some flashlights and your camera and head to the basement for some light saber photography. I assure you it will be more fun than basic light painting.
Tomorrow's challenge is Colorful Water Droplets, or using water droplets as a refractive lens. Expert Photography shows you how to execute this trick at How to Create Colorful Water Droplet Photos. I have seen some amazing photos using a similar method, and I'm curious to try it myself. I could see my kids getting into this one, if I let them help again.
What do you think? Are challenges like light painting and water droplets fun exercises to try or useless diversions from practicing photography basics?
