Having read about and seen the results from the flash set up that Adrian uses for macro photography on ADRIAN'S IMAGES I decided it was time to have a go as I usually use just an LED ring flash and a LED lamp.
I bought a bracket combination which would hold two flash guns complete with a Y splitter so both could be connected to, and fired at the same time by, the Canon 50D. That was the theory but was almost impossible to get working in practice. Maybe the matched pair of cheap flash guns I also bought kept interfering with each other. Whatever the reason either both would keep flashing like some demented lightning storm or just plain refuse to work. It took a couple of hours faffing about trying all sorts of changes to various settings and a card full of blank or over exposed shots to sort things out.
In the end I dug out my old Canon Speedlight, added an extra short bracket so the Canon was connected to the Speedlight and the ring flash. The remaining flash gun was set up as a slave so it would fire as soon as it saw the flash from the Speedlight. The guns were fitted with their diffusers and all set for minimum light output. Now things were cooking with gas and worked properly every time.
The lens combination is the Canon 70-200mm zoom lens fitted with a Raynox Super Macro Conversion Lens. My patient subject was a juicy 35mm Asda strawberry, now scoffed as part of my tea and very tasty it was too.
The lens was manually set to f10 and lighting adjusted to get a reasonably lit shot. With my old set up the aperture would have been around f4. At least f10 gave a better depth of focus.
