On Thursday I had one of those all too few flashes of inspiration. Why not use the intervalometer that I use for time lapse photography to monitor the pond waterfall. To that end I set up a 350D on a sturdy tripod at the opposite end of the pond and set the electronics to take a photo about once every twenty seconds. Over three hours it took nearly a thousand photos a few of which did manage to capture a few of our feathered friends.
Nothing out of the ordinary as yet. The first was a House Sparrow peeping to see if it was being watched.
They are very communal birds so there are normally several together.
I wonder how many you can spot here:
Easier to count this time.
And finally a male Blackbird with a Wood Pigeon.
As I said, nothing out of the ordinary but I have learned a few things. The idea works, just have to be patient. My chosen spot, where I needed to have a telephoto lens with fixed focus, meant a shallow depth of field. The weeds in the way are too far in the pond to reach for pruning. I have sussed a better spot nearer the waterfall where I can get closer and probably use a 50mm lens. Of course it rained most of yesterday and is raining again this morning so I will have to wait for finer weather to have a second go.
The basic set up for time lapse photography can be seen here. In case you are wondering it doesn't take very long to check a thousand photos. I copy them to the hard drive (that takes the longest) and use IrfanView to view them. I just keep hitting the 'next' key and with the view being the same in each photo any changes show immediately. Those with activity I move to a folder and then delete the rest.
I use an old second hand camera as this technique is hard on the shutter / mirror mechanism and can give a years wear in a day. To make the camera battery last the session I turn off the LCD display as that uses a lot of energy in displaying each shot.
