Berberis Darwinii - macro

I blipped our lovely berberis on 25th April (here), but as it's still looking so nice I thought it could merit another blip.

As Walking Wombat is running a May Macro Mayhem challenge, it seemed sensible to do a macro this time. To give an idea of scale, the whole flower is only 2 cm across.

(If you're interested, I'm still using my makeshift macro system, with the addition of the little LED lights I had for Christmas, and post-processing with a multi-layer focus stack in Photoshop. The cheap extension tubes I bought recently had to go back as they didn't work properly; I'm wondering about getting a better set soon!)
