Baboons (Papio cynocephalus) when safely ensconced up a tree always seem to take flight and desert the tree when even slightly threatened during the day. More commonly than not they reverse down the trunk as fast as they can! It usually happens so fast, that the cameraman needs to be quick to action. At night time baboons, typically, do not budge and remain hidden away aloft the tree.

Gaussian Blur is the result of a digital adjustment using graphics software which effects the blurring of a part or the entire image. With some skill, it may emulate the effect of depth of field achieved through aperture adjustment in camera, but its use more generally is to reduce noise and detail in the image. The difference between Gaussian blur and bokeh is in the creation. One is created optically and the other is post-production adjustment. Bokeh is three dimensional and less smooth.
“Here, then, was a paradox of picture taking that appeared from the start. Despite its promise of the ultimate document, of a picture more realistic than art could achieve, the camera was also an instrument of artifice and posing, even fakery and deceit. The invention that enabled people to write with the sun would blur the distinction between appearance and reality, between the image and the event.”
