Well there you go - Silence is Golden - Come Feel the Noise - The shot can be quite quiet or crash bang! - The idea being to; use movement (slow shutter perhaps?) , point of view (perspective) and or colour (mono tones if you like)to provide some sense of the physical sound; if that makes sense.

The hardest bit is the choice of subject/s and a bit of trial an error experimentation (unless you are lucky to capture a bird beak wide in song) etc., until you get the shot you feel does the job for you. Hence the additional day to play and perfect your entry.

Happy shooting
