Your DSLR can take outstanding photos on its own in auto mode, so why would you want to switch to manual? This video tutorial will explain the reasons why as a photographer you might want full manual...

Eastward, beyond the surf of the Pacific, beyond the tawny rolling
Coast Range and the wide central valley of California, rises the great wall of
the Sierra Nevada. Four hundred miles long, seventy-five miles wide, ten to more
than fourteen thousand feet in height, it ranks with the major mountain ranges of
the world. Certainly it is one of the most beautiful. Geologically, it is a
titled block of the earth's crust -- a long, continuous slope fronting the west,
and a short, breath-taking decline to the eastern deserts.
Truly the "Range of Light," as John Muir defined it, the Sierra Nevada rises
to the sun as a vast shining world of stone and snow and foaming waters, mellowed
by the forests growing upon it and the clouds and storms that flow over it.

In the White Mountains, just east of the Sierra. Some of these trees are 4,000

Sequoia/Kings Canyon National Parks
These parks include Mt. Whitney (14,495', highest peak in the Lower 48) and
catch all the rain so that it doesn't fall on the dry Eastern Sierra. The Giant
Sequoia can live up to 3,200 years and typically grow to a height of over 200
feet. They are the largest living things on earth.
