Stock photography and kids have one thing in common - they make you more aware of your surroundings. Some people talk about seeing the world through your children's eyes, but I actually find I'm pretty darn interested in the world all on my own - kids just add to that by having some else around who is amazed as well.
On the weekend two of my sons and I were at their cross country ski lessons and they noticed some big snowflakes on their jackets. I grabbed my (super handy and compact) Olympus OM-D, tiny 14mm pancake lens and a 10mm extension tube that I keep handy and started looking for interesting snowflakes on the window of the car. The tinted window made a nice background of black to offset the ice crystals and flakes. It is often tricky to find 'perfect' snowflakes as they don't always land flat, or there are too many piled up to get a shot of just one. But as the snow was starting, it didn't take long to get a closeup and show the kids. At first they were rolling their eyes as Dad took yet another photo - but when I showed them the stellar snowflake up close on the back of the camera they were suitably amazed!
I find that stock photography keeps me on my toes in terms of always being aware of both the big things around us and the tiny. There is definitely beauty all around us, even at the tiniest of levels...
