One of the things I've tried over the past few weeks is to capture a water splash frozen, sharp and in focus. I'd tried this last year and got some OK results, but they weren't fantastic and it was very hit and miss.
This time I wanted to be sure I understood the principles, and thanks to a few people I think I'm getting there, and I thought I'd share.
First some simple things to remember.
- Water is transparent. (No shit Sherlock...). No, this is really important and I didn't consider it with my first attempts. I was more concerned with a clean splash and it was only when I reviewed them that I realised the cloth under the water wasn't particularly photogenic
- Water is reflective. (again, with the Sherlock remark). Seriously, take care of the background lights (and remember to wear some clothes if you think you'll be in the reflection)
- Water is wet. (OK, but still....). Make sure you don't have anything valuable sitting where it will get wet. If you're fiddling with positioning of lights and bowls and backgrounds, make sure your camera isn't around your neck and dangling in the water. It's obvious, but I found my camera remote (my new one) in a puddle after one session
And if you ever needed proof that water was transparent, the splash is lost in a poorly conceived background choice.
OK, here's what you'll need.
- A clear bowl or some other water receptacle (preferably with water in it) - I used a shallow casserole dish
- Something to go under the bowl if it's transparent - I used place mats, card of different colours, paper and a few other things while playing
- Something to drip the water into the bowl - I used a syringe, but have read about people using plastic bags with pin holes, pipettes, basically anything that allows you to control the flow of water at drip level
- Light
- An empty memory card (you will take a lot of pictures)
- Tripod
- Camera remote (optional)
The first three are pretty straightforward and what you use is entirely up to you. Different containers and colours will have huge impacts on the final picture and you really should consider the background as it will make or break the image.
Light is important. Remember, the aim is to catch a splash. To freeze it in motion you'll need to use a pretty fast shutter speed and unless you happen to be shooting outdoors on a nice day, you're already climbing a lighting mountain. You have two options, either a fixed constant light source or a good flash gun. I'm not going to try and tell you to use one over the other, but remember a typical flash will have a maximum synchronisation speed of about 1/200 and that might limit you somewhat.
Right, so assuming you've all the bits above, you need to do the following...
- Position your background on a solid stable location
- Place the water (in the bowl) on top of the background and make sure there are no specs of dirt in it
- Set up the camera on the tripod pointing at the water
- Make sure your camera is in manual focus mode
- Use the end of your dropper (or something thin like a pen) to pre-focus on the water roughly where your drop will hit
- Try to get as narrow an aperture* as you can get away with without reducing the shutter speed too far. I found 1/200 was the absolute slowest I could get a sharp(ish) image at. (your mileage may vary)
- Finalise the settings on the camera, set up your lighting solution (if you're using a flash a few test shots to make sure you have a decent exposure wouldn't go amiss). Put the camera on continuous/burst mode
- Holding the dropper above the water, aim for your chosen spot
- Fire the camera as you squeeze water droplets out of the dropper. I started by using the remote, but found it was as easy to just use one hand for the dropper and the other for the camera button
- Refill, repeat until the card is full
*(Why the narrow aperture? Well, the likelihood of you hitting the right spot with every drop is slim. With a narrow aperture you get a bigger depth of field so are more likely to get a good sharp drop in another region of your picture, allowing you come latitude for post process cropping.)
It takes some patience, and a lot of trial and error. But hopefully you'll get a few decent splashes captured.
(This is also a decent example of the need for a small aperture as the splash is way off centre. The high spot in the splash is from the flash gun - and that was with a diffuser on it!)
Now I've managed it with water, I'm planning on trying it with milk and a few other liquids. I'm also going to give it a god with a different lighting setup - possibly off camera to see how that impacts it.
Hopefully this has been of some use. There are a few of these guides on the web. The best I found was on Caz Photo.
Also, if you want a better understanding of why flashguns have a maximum synchronisation speed, you'd be well advised to read Paulo's explanation.
