Crown Jewels

Posted by Caz on Wednesday, 11th January 2012

After yesterday’s success with double droplet collisions, today I thought I would try and make some double crown shots. I’ve not seen anyone do these on Flickr before, so I hope you like them. Here’s the setup:

As with my other crown shots, the valves are dropping onto perspex. In the past, I’ve had reasonable success but not really seen some of the long tendrils I’ve noticed in other people’s pictures.

Initial shots - fairly boring shapes

Initially I was getting the standard fairly boring shapes – crowns, yes, but not much in the way of splashes from the rims. I had a brainwave and decided to add a drop of Rinse Aid into each of the drop pools when they first form and see what happened. (I’ve used Rinse Aid in the bowl when doing splash collisions, but never for crowns on a flat surface before). All of a sudden, more interesting shapes began to appear!

There are some great patterns there, I’m very pleased. My ultimate image for the day, containing a “King and Queen” crown was Day #1472.

Double Trouble

As if single splash shots weren’t hard enough, today I decided to give myself even more of a headache and attempt a double splash shot – two collisions simultaneously from two vavles (I took delivery of a second Valve Sensor for the Camera Axe just after Christmas). There has also recently been an upgrade to the Camera Axe software to allow the control of two valves at once.

Timing and alignment are both crucial, as you might imagine. Whilst I have only really scratched the surface of what can be achieved with the pair, I’m quite pleased with the results from my first attempt. There weren’t many coherent collisions (as I have to work on the alignment being more accurate) but there are some more abstract shots – see in them what you will!

Favourite from the shoot was chosen for Day #1471 – one of the few coherent double collisions I did manage to capture today.

A Splash Of Rainbows

I got back into the studio yesterday to do some more water splash shots. This time I was playing with different backgrounds to give it some variety and using some holographic paper, lit from each side with a snooted flash:

The results were very pleasing:

Favourite of the day (only just, since it was taken at 23:59!) was Day #1469.

Water Splashes – Improvements

Posted by Caz on Wednesday, 14th December 2011

I enjoyed another water splash session in the studio yesterday. At last I think I’m making progress in terms of getting good shapes and more coloured lighting. The flash setup was pretty similar to this, but I was using various coloured gels on the perspex in the background, and the blue drips were plopping into a blue coloured bowl below, rather onto a hard surface. Here is a fun one to start with (milk rather than blue-coloured water):

There are so many variables you can tweak that it’s a good idea to just experiment with one thing at a time. Today I was seeing what happened with using drop 2 at about 75% the size of drop 1. The answer – interesting stuff! The collision “hats” seem to get thinner and longer tendrils appear. It also helps to add a few drops of Rinse Aid to the pool they are splashing into. Here are a selection of the best ones which nearly made it for Day #1443:

With my current valve sensor setup, the depth of water in the valve reservoir is also pretty critical – once the initial measurements are done, the timings can vary wildly if the head of pressure changes too much – so I was tending to keep it topped up between 25-30ml for each shot. This gave me much more consistency and stopped me from going mad. I really need to build a Marriotte syphon to get around this issue. But that’s for another day.

Playing With My Food

Posted by Caz on Sunday, 11th December 2011

It might be fair to say that I enjoy playing with my food from time to time. There’s nothing better than a photoshoot after which you can eat the subject! Today I had an idea for some splash shots showing a runny boiled egg and soldiers…

There was no way I was letting sticky egg yolk anywhere near my valve sensor – that would be a sure way to bung it up for good. So I improvised with skimmed milk and yellow food dye. The results looked quite convincing!

Incidentally, I got to eat the hard-boiled egg yolk before the shoot this time – as I wanted it out of the egg but left the white to contain the splashes nicely.

This set follow on well from my Coffee Cliché series. I can see the basis of a theme developing – watch out for more in future!
