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.
In this post I explain the optics of an SLR and compare it to viewfinders from mirrorless cameras. A single-lens reflex camera uses a mirror (hence the term reflex) and a pentaprism that allows the photographer to look through the lens and see exactly what will be captured in the photograph. A digital single lens reflex camera is a camera that combines the optics of an SLR with a digital imaging sensor.
