"As many of these photos suggest, Australians seem to have a great sense of humor about themselves and their country-making a visit seem even more enticing.  Especially when you combine that with the unique animals and natural wonders.  Did you know Australia has camels and penguins as well as its most famous and beloved cuties?"

"Color depth, also known as bit depth, is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video frame buffer, or the number of bits used for each color component of a single pixel.[1][2][3][4] For consumer video standards, such as High Efficiency Video Coding (H.265), the bit depth specifies the number of bits used for each color component.[1][2][3][4] When referring to a pixel the concept can be defined as bits per pixel (bpp), which specifies the number of bits used.

Ansel Adams Photographs In 1941 the National Park Service commissioned noted photographer Ansel Adams to create a photo mural for the Department of the Interior Building in Washington, DC. The theme was to be nature as exemplified and protected in the U.S. National Parks. The project was halted because of World War II and never resumed. The holdings of the National Archives Still Picture Branch include 226 photographs taken for this project, most of them signed and captioned by Adams. They were taken at the Grand Canyon, Grand Teton, Kings Canyon, Mesa Verde, Rocky Mountain, Yellowstone, Yosemite, Carlsbad Caverns, Glacier, and Zion National Parks; Death Valley, Saguaro, and Canyon de Chelly National Monuments. Other pictures were taken at the Boulder Dam; Acoma Pueblo, NM; San Idelfonso, NM; Taos Pueblo, NM; Tuba City, AZ; Walpi, AZ; and Owens Valley, CA. Many of the latter locations show Navajo and Pueblo Indians, their homes and activities.

"A frequent question to landscape photographers is: "What filter did you use in that photograph?" This is usually because the person doesn't believe the colours and tones in the photograph are real, and thinks that the photographer has used one of the many 'effect' filters on the market to achieve the result. The truth is that no filter can substitute for being in the right place at the right time to capture the most spectacular light. That's not to say that filters aren't important, however. Properly used, filters allow the photographer to capture a scene that would be virtually impossible to photograph otherwise. I'm talking about those known as graduated neutral density filters, sometimes also referred to as split neutral density."
