I'll try to do one of these every few days over the next few weeks as there are lot's of interesting flowers coming in our garden. I am allowed out there occasionally, but I have to do my 'cutting' in secret to avoid the wrath of the Head Gardener.
Eight manually focussed shots using a 5D MkII (lovely camera!) and a Sigma 105mm macro with 21mm of extension tube added to get in closer. Stacked together in CS5 (which is just as good as Helicon in my opinion). Studio lit indoors. The flower is about 3cm across, so I had to get in quite close to fill the frame - just a slight crop.
Looks better on black
