A few images from my journey by train to Bath. All have an element of waiting.
The many repeated objects in the last image appealed as well as the cones

Four-spotted chaser
A visit to Wicken Fen provided an opportunity to photograph a Four-Spotted Chaser that had just emerged from its larval case. I used various lens combinations to see what worked best. In each of the pairs, the first is the 50 macro lens with converter to give life size and with a ringflash. The second is the 100-400mm with a 25mm extension tube used at 400mm end in second photo and 100 end in fourth.

Travels with the Infrared
Some images from trip to Kings Lynn to lecture - not very good weather but took a few shots with the infrared camera.
Peppered Moth
Very pleased to catch a Peppered Moth in my light trap last night as it was very much part of my biology teaching through the years. When first studied 200 years ago, all moths were like this one, pale and speckled and so hidden from predators on lichen-covered branches. With Industrialisation, lichens died out and trunks were generally soot covered. This led to the selection of the naturally occurring dark forms and predation of the light forms. The melanistic form predominated up to the second half of the 20th Century.
With the advent of smoke-free zones and the loss of heavy polluting industry, the light form is now reestablished.

Ely Eventing
I tried various techniques at this event and found that panned shots at 1/200th second gave the best spray. I will post some faster shutterspeed images later.
We had been at this event for 7 hours when Bryan rightly suggested we should go back and start downloading the numerous images. I said 5 more horses or 5 minutes more at the water splash. The this happened. Fortunately neither rider nor horse were injured though the rapid inflation of the safety jacket caused some discomfort.

Fenland Railway
Some images of the Level crossing at Pymore - not sure how I will finally process and print the images but quite like this old feel to the photos - they remind me of the sort of prints that you see in some self-catering cottages that have been on the wall in the sun for a long time and faded

Trying Longer Macro Lens
Bryan kindly lent me his Sigma 180 mm Macro lens so I took it Damselfly photographing at Paxton Pits. I like the distance that you have between subject and lens but find that to handhold the long lens requires a fairly fast shutterspeed and so depth of field is fairly limited on the resulting aperture. The two images above were taken with the 180 macro and are Blue-tailed Damselfly and immature male Common Damselfly

Confusion on Warblers - Solved!!
A Bank Holiday walk around Paxton Pits this afternoon was rewarded with these great images of a warbler feeding its nestlings with a great variety of flying insects. I was sure that it was a Willow Warbler but everyone who looked said eye-stripe therefore Sedge Warbler. However, I am not convinced as there is no streaking on back or breast. I will post it on the bird ID Forum that I subscribe to so more to follow.
It is a Willow Warbler - identified on the Bird ID site.

Broad-bodied Chaser
Further tests with the 25mm extension tube. The first is taken at f18 and the tips of wing and abdomen are not quite in focus.
The second has the maximum aperture setting f40 and is now just about all in focus - the shutterspeed at ISO 640 is now 1/20 sec so only one out of six pictures didn't have some movement.
Photographing damselflies
There were several pairs of red damselflies laying their eggs in the pond this morning. I tried a method that I used last year to get closer to the insects - a 25mm extension tube with the 400m end of the 100-400mm. The first picture is just about full frame. The main problem is depth of field. With the bright sunlight, I could use f40 to give maximum depth.
