Frog Croaking

[digartal]

Frogs generally don't croak when a light is on them. Thanks to a technique shared by Craig Mayne in another photograhic group, I was able to capture this series of 68 images last night.

To croak, a frog inflates its lungs, closes its mouth and nostrils, and forces air through its larynx and into its vocal sac. The air then passes back and forth between the vocal sac and the lungs, causing the vocal cords to vibrate and produce sound. This side on view endeavours to show this process.

I recorded the sound of the frog calling on the mobile but flash and sound are not sync'd. With some editing it could be improved but the sound does give some idea of the process. I am not sure that any more will happen with this so spending more time is probably not warranted.

Camera set up on tripod - framed and  focused, flash modelling light off, capture the 68 images with flash when frog starts croaking. 
Grateful to have this wildlife in my backyard and the very patient frog who assisted with this process over a few hours.
Full frame Sony A7RV, Sony 90 mm Macro Lens, Godox Sony Flash plus pateince and practice.
