Work In Progress: Cosmos

Off-Shoot from another project. These are some test images I took of balloons bursting with a small amount of water sprayed onto the surface. I added some colour in post as an experiment and was left with these almost galaxy-appearing images.

The latex contracts very rapidly as the balloon is burst leaving the water and particles in mid-air for a brief moment before they are pulled down by gravity. The trick is to get the timing right and rely on the flash to stop the motion rather than the actual shutter. The photos were shot using a Triggertrap V1 set to trip an SB-900 based on the sound of the balloon bursting. I used an SB-700 on the backside of the balloon to balance the light and so that the power of each light could be set to their minimum. This keeps the flash duration short while allowing ample light to make the exposure, in this case the images were exposed around the 1/35,000th of a second mark even though the shutter speed was set to 1 second (shot in a dark room to prevent any noticeable ghosting from the long exposure).

Production process from the original image, to the final coloured image.

The final images were somewhat interesting but will need some more fine-tuning or experimentation with colour. The galaxy-like appearance of the coloured images was added in post however I think I would be possible to do in camera with careful gelling and multiples lights.
