Female flower bee in flight

Posted by wildwatertv on April 29, 2010

This is another hairy footed flower bee (Anthophora plumipes).  There are lots around at the moment, but they disappear by the end of May.  This high speed photograph shows the opening of the sheath around the long tongue as the bee approaches a pulmonaria flower.   This sheath gets folded back as the bee feeds and then it snaps shut again before moving on to the next flower.  The male is shown in an earlier post, but this is the female, with pollen baskets on her hind legs.  Many of these are living in holes in the wall of our cottage.

Hairy footed flower bee

Posted by wildwatertv on April 14, 2010

I spent ages last week setting up the equipment to do high speed photography on bees in flight.  Finally, I got this one to play and it took its own picture.  It looked a little odd when it came to identifying it.  I first thought it was a bee-fly, but on further investigation it IS a bee called the hairy footed flower bee, or to give it its scientific name, Anthophora plumipes. They have very long tongues, which can get to the nectaries of pulmonaria.  They are hole dwellers and our house has holes made by mason bees in which they probably live.  the females are all black, but this is the male.  They are among the earliest of bees, and only fly until about May.

Another balloon being shot

Posted by wildwatertv on March 24, 2010

I bought a new Chinese air rifle yesterday for using in just this way, it’s pretty powerful and the pellet is travelling at 500 feet per second as it bursts the smoke filled balloon showing clearly the sound wave that is generated by the ‘pop’.  It’s so fast that the balloon still retains its shape as the pellet leaves the frame.  This is similar to another image on the blog, but with all new digital techniques.  Still looking to speed the flash up a little to freeze the leading edge of the rubber as it moves, but the speeds are unimaginably fast.

Water drops

Posted by wildwatertv on December 3, 2009

This is the result of experimenting with lighting liquids.  The photographs are standard high speed water drops, but lit in particular ways to make the three dimensional quality of the coloured coronets stand out. Essentially the technique involves lighting the liquid through itself to eliminate any reflections or distracting highlights.  I never get tired of seeing the random nature of these moments in time.  Sometimes what you can’t see is much more beautiful than what you can.  The action is frozen using high speed flash triggered by an infra-red beam and shot through a 1930’s Rapax shutter attached to the front of a Micro-nikkor 105mm f/4 lens.  Very often old equipment is better than new equipment.

Dandelions blowing in the wind

Posted by wildwatertv on November 25, 2009

High speed dandelion seeds.  It took over 200 separate dandelion heads to produce about ten usable photographs.  The way the seeds leave the head is at best unpredictable.  Photo taken using an infra-red trigger and flash at about 1/50,000 second to freeze the seeds in the air.  Nikon D300, Micro-Nikkor 105/4.

High-Speed Balloon

My photo of the week.  This is an interesting image.  It shows an air gun pellet bursting a smoke-filled balloon.  You can see the sound wave generated by the pop of the balloon frozen in the smoke.  Science isn’t all boring….
