Ian (Xmetal) kindly lent me his f/1.8 50mm Canon lens to experiment with, and I was using it to capture some water shots I've been experimenting with, and learn more about my camera and its controls in the process.
Anyway, a few hours before I gave it back to him (thanks again, man!), i went out to experiment with different apertures to see what results I would get regarding depth of field... My old man had his car parked out the front, and it was a good time of day with the sun starting to set, so off I went outside with camera and tripod... I haven't done any post-processing on the shots.
Here are the two extremes of aperture and how they affected the DoF in the shot;
f1.8, 1/500 shutter speed, ISO-200
f/22, 1/13 shutter speed, ISO-800
