Got the itchy shutter finger again this morning. Went out to some old haunts. I shoot these same cacti in the spring when they're covered with big yellow blooms. Now the bulbs have turned...? I'm not too sure of the color but that's what fascinating about nature...comes up with the weirdest stuff. The color reminds me of a radish. So we'll go with radish purplish reddish.
Shot these with the D80 (with polarizer) set to ISO 400 and aperture priority @ f5.6. Large clouds were skirting by so the light is different in each one. The top one was 1/5ooth of a second, the middle one is 1/250th and the bottom was at 1/125th.
Nature note: for the top one I held the camera at arm's length down into the cactus pointing up to include the sky. So I really couldn't see the shot..needed several to get the feel. After a couple of these shots the barrel of the lens was covered in needles which also invaded my fingers. Took about 15 minutes to pull them all out. And at home with the tweezers for a couple of stubborn ones. I think someone once said you have to suffer for your art! So beware if you try this! Don't be like me...wear thick gloves.
