Yeah, sorry not quite what I meant. I know the aperture blades (number and shape) create the shape of the discs, but without light sources behind you don't get the discs do you? I've only ever got them with light sources behind, the classic example being Christmas Fairy lights.RIGHT! Bokeh is not aperture dependent but distance subject/background dependent!
Furthermore, if one creates bokeh using a large aperture the price to pay, as with the bird,
is a consequent loss of sharpness due diffraction. These monkeys are a perfect example
of this. …a very cool shot by the way snerkler!
WRONG! The shape is strictly determined by the number of blades of the diaphragm which,
to be of desirable quality, should count 9 or more blades.
im trying to create it in my photos,I've achieved it sometimes with lots of round discs behind the subject but it was luck,my 50 mm 1.8 gets me the best results,I know get close to your subject and have the background well back but what the best distance from subject to background?whats the best natural background?i haven't a clue.
What a great place the world was, before everyone started using the word "bokeh".
