During Certain Times Of The Year, Some Slot Canyons Yield To Overhead Light Pouring In Through Small Crevasses And Produce A Fantastic Array Of Colors And Textures. The High Desert Of The Southwest Is The Home Of Most Of These Beautiful Slots Where Raging Water And Eons Of Time Have Carved A Labyrinth Through The Soft Sandstone. Indirect Light Bouncing Off The Interior Stone Walls Produces Stunning Combinations Of Purples, Blues, Oranges And Reds. This Kind Of Work Demands Very Wide Angle Lenses In The 14-20mm Range So That Enough Of The View Can Be Recorded In One Frame. You Can See The Brightness Or Source Of The Noonday Sunlight And Note The Difference In The Light's Quality In The Center Of This Commercial Landscape Photograph By Brian Buckner Photography, Shreveport, Louisiana.
