Macro Shot of a Phalaenopsis Orchid

Phalaenopsis Orchid (Canon EOS 5D Mark II, Sigma 105mm f/2.8 DG Marco lens, 1 sec at f/16, ISO 100, tripod)

This is a macro shot of Aileen's Phalaenopsis Orchid (at least I think that is the correct type of orchid), which I noticed was in full flower today.  It was sitting on the window sill nicely lit by the overcast daylight, against a beige backdrop.  I decided to try a simple macro shot and set up pretty quickly using my 105mm macro lens set at a fairly small aperture to maintain a decent depth of field.  The petals on the extreme left of the rear flower-head are a little bit bright at the edges for my liking, but otherwise it came out quite nicely.  I tried a couple of different apertures which resulted in much shallower depth of field and didn't really like the results.  The image didn't need much by way of post precoessing, just removal of dust spots from my sensor and a little adjustment to the exposure and whites and an small increase in the luminence of the reds and oranges to bring up the darkened areas at the centre of the flower heads.
