My oldest daughter loves mushrooms (she is now growing them in a box in our basement) and we enjoy photographing these marvels together. This purple mushrooms is one of my take-homes from an outing together.
For this shot, I rested the camera on my hands which were against the ground. I used the Canon EOS 60D's Vari-Angle LCD to make shooting from ground level an easy and comfortable task.
The Sigma 17-70's OS allowed me to shoot at 1/6 seconds without a tripod. Using a 17mm focal length from a close distance makes the viewer feel more like part of the scene.
