Pick one, only one lens - don't let anyone pry it from your fingers - and head on out for a few hours shooting. This is one of my favorite things to do when I want to head on out to a relaxing, not for pay, photo shoot. Giving yourself only one lens choice forces you to concentrate on the subject, the colors, the composition - the gadgetry is left behind. Only your attention to the subject remains. It's a good place to be when you are in the creative process. I posted just such an exercise several weeks ago where I used a macro lens for all the shots. You can re-read the "Up Close and Personal" post right here.
My favorite lens for this kind of shoot 24-105 IS, 100mm macro ( boy, I sure wish Canon made an IS macro like Nikon has), 70-300 mm IS, 10-22mm wide angle, and maybe the fisheye. I tried this exercise with the fisheye a few days ago and kept shooting my feet. When we get back in town, I'm going to pick up some extension tubes - then I will really be ready - Fisheye macro photography. Anyway, I hope you get the idea here - it's just fun to play. In a few hours, we are heading out on a walk to explore our surrounds here in Cabo. I'm all set up with my 100mm macro. I'll share a few images tomorrow.
