A 9-microsecond capture illustrating the interaction of an apple with a flat head air rifle pellet (paper puncher).

Thank you Gordon :D

I am looking for ideas for new subjects using HSF and ask for everyone's input. Surely there is more to this than shot eggs, shot light bulbs and water splashes? But my rapidly diminishing numbers of brain cells can't actually come up with anything new and exciting in this area. Anyone got anything they would like to see taken at HSF which would be visually interesting/striking?

Greg

Thank you Joe :D There's quite a lot of HSF stuff around, but there is very little done at 9-microseconds :shock: :shock:

id love to help you come up with new ideas.
can you please explain quickly how you do these? is the shutter open for a long time and the action is frozen by the flash? how do you trigger it?

ok one example: how about a big firecracker exploding?

could look interesting because the pieces of paper flying away would be frozen by the flash, while the explosion itself will be some kind of blur because it provides light itself.

Not a good idea to have the subject itself emitting the light, might as well just photograph the firecracker by triggering the camera shutter with the sound of the cracker going off. But keep thinking
Greg :D

well i think that could create some very interesting effect (having the explosion AND the pieces of the cracker). surely your flash is brighter than the explosion and can freeze most flying parts. also you could for example put the flash behind the cracker or on the side of it to create some more dramatic effect than the frontal setup you have on that apple.

so you use sound as a trigger?
and because of the flash setup i suppose you cant do it outdoors where ambient light is around?

I use sound triggers, light beam triggers, and straight firing off the camera shutter.

The units can be used outdoors in ambient light, you just have to be careful how you set things up.

ok im sure that has been done before, but i would like to see some balls getting hit real hard.

for example a baseball, golfball or football (the round version preferrably).
you could hang the ball in place or set it up on a little stand. then hit it with the appropriate bat, club or your foot as hard as you can and capture it at the moment of greatest deformation. :D

next idea:

ive seen pictures of a bursting waterballoon with the rubber skin shrinking and exposing the water which keeps its shape for a while. it would be cool if you could to this by completely removing the rubber so its not visible in the picture :shock:

you probably would need to build something that pulls the rubber away really fast as soon as it tears. like rubberstrings attached on two opposing sides of the balloon. then you puncture it in the middle with a tiny kind of projectile and hit the shutter as soon as the rubber is not in the frame anymore...

now it gets dangerous:

there are these 12 gauge shotgun slugs:

http://media.midwayusa.com/ProductImage ... 553339.jpg
http://www.2ndamendmentshootingsupply.c ... 202726.jpg

when you shoot them on a hard, round object (a big round pebble for example), they get squashed and teared to pieces. it would be cool to see that moment.

put a nice looking, opaque vase on a table, and make it explode (firecracker!). capture the moment when it is already cracked, but still pretty much in its original shape - so it looks like floating shards.
