Nope, I didn't use a CPL (would have, could have, but my lens was too WA and I didn't want to mess with the sky). We were on our way to shoot Coyotes Buttes South and stopped off to shoot a...

Bill, thanks for your input! Regards, Joe Kurkjian Galleries: http://www.pbase.com/jkurkjia -- http://www.pbase.com/jkurkjia/image/79836867/original.jpg ...

Hi Bill, First off, thanks, I'm glad you liked the shots. I wouldn't consider going to that area unless the weather was good (from the standpoint of both photography and driving) ... so, I've...

From a trip last week, a couple of panos (stitched using PTGui) taken with a 50D/17-40. Thanks for looking and I hope you enjoy the pictures ... C&C welcome. . . A "painted desert look" mixed...

Hi Jerry, For a given lens a crop frame only changes the field of view, not perspective (camera to object distance changes...

foot zooming changes perspective and that's not always a good thing. Regards, Joe Kurkjian Galleries:...
