Most full-spectrum digital cameras can detect some ultraviolet, all of the visible and much of the near infrared spectrum (350 nm to 1000 nm). However, the longer infrared waves are recorded the strongest and remove much of the visible light in the blue and green areas in a full spectrum photograph. Here are some examples from a day in the Cambridge Botanic Gardens yesterday. Interested how the Greenbottle's metallic colours recorded so strongly despite the background information above!. The first image, taken with a lot of green foliage overhead cutting out some of the shorter wavelengths, reminded me of trips to northern Scandinavia and the views as our small plane came into land!!
As Chris was away for yesterday's match, I went along to photograph CRUFC's match against Ealing, a fully professional team. The result was as expected (17-52) but Cambridge managed three tries and fought hard.
For about 15 minutes I was entertained by a very large flock of mixed small birds - warblers, Chiffchaff and Black Cap, Blue Tits and Goldfinches feeding on the abundant midges (!) and seeds respectively. Such a pleasure to see large numbers of small birds after a difficult summer for them with the hot dry weather.
My first visit to Otmoor (Oxfordshire) and was rewarded with some great sightings - Common Crane, Bittern, Heron, Red Kite with Prey in Talons, Heron and Spiked Shieldbug with its impaled caterpillar prey. There were also some better photographic opportunities of small birds - next Blog. The Grass Snake was nearer Aylesbury on a stopover.
