Why do koalas spend so much time sleeping? Koalas need to conserve as much energy as possible, as the energy value of their diet is low. Koalas generally sleep for about 16 to 18 hours a day. A common misconception is that they are âstonedâ after eating the eucalypt leaf. This is not so.
HDR is an abbreviation for high dynamic range between the darkest and the lightest parts of an image. An HDR photo displays maximum details for recreating all the memories and get you back to the moments of shooting. HDR Photography is a science and an art.
A good tip for digital SLR users is to shoot in the RAW format (which you should do for the best quality colour to black and white conversions anyway) but set the Picture Style (this is Canon's term-check your instruction manual if you have another brand of camera) to a black and white mode.lack and white is a very effective medium for landscape photography. It draws attention to the shapes and forms of the components within the landscape, and the quality of light. This photo, taken on the Bolivian altiplano, is reduced to a series of shapes and blocks of light and dark tones in black and white.
