water drops

Had a chance to shoot more water drops the other day. This time I had a real macro lens and an pcb einstein to work with. I also used a 580ex, but can't remember which ones. For both the power was at near minimum and aimed at a red background.
For the dropper I used a ziploc bag suspended so one corner was hanging down and poked a hole there. The drops were pretty steady and not too fast or slow.
Depth of field is ridiculously shallow that close, even at f/16, so focusing was tough. I think I'd start a drip, then hold something, like the pin I used to stab the water bag, where the drops were hitting, with one hand while focusing with the other.

High speed sync flash - water drops

Not hard to set up, but difficult to get right. High speed sync is just a button on a flash, but it lets me shoot at 1/8000th of a second. Setting the flash inches from the glass of water allows me to shoot at f/8 too... and it gets the flash wet.
I had the flash connected to the camera with two off camera hot shoe cords. I liked the light coming from behind and aimed up a little. Shutter speed and aperture were 1/8000 & f/8 mostly. ISO between 100-400. The camera was on a tripod and the lens was as close as it could focus. Live view helps a lot. I had one glass filled with water and poured water into it with one hand while I held down the button the cable release with the other. Flash was in manual mode at 1/128 or 1/64. Paper towels were everywhere.
