Was in the hide at Dawlish Warren a few months ago with not a lot going on so decided to stack 2x and 1.4x convertors on the 1DSmk11 to see how close I could get the Oystercatchers on the small island in front of the hide. Suddenly a crow used the oystercatchers as cover darted through them, scattering them in the proces and in the confusion grabbed a juv. sandwich tern which it then killed and started feeding to its young. Took a whole series of images from the first attack to the discarded carcas. This is one towards the end of the attack.
Having talking to Nigel Blake at the Murrelet twitch I have approached the resizing of the image in a different way. I have retained the 1DS image size and increased the image approx 200% to get the part of the image I wanted to keep to fill the frame. This was done by increasing the size of the original file 200% by using 4% image resizes about 18 times this has given a far better enlargement of the originl file then the one jump from 100 to 200%. No doubt that 2% 36 times would yet again increase the quality of the final image. Lots of other work done on Photoshop to retain detail in both blacks and whites. An interesting technique that works well and worth considering if you need to increase the size of an original file for a much larger print. (Nigel, many thanks for the technique, also Photomatix will be very useful for the property workflow) This technique works very well with sharp images from the 500mm lens alone, I just wanted to try something completely over the top.

Interesting shot - seen similar myself - crow killing rabbit - and technique (which everyone will be trying now).
Doesn't Photoshop CS / CS2 use some kind of stair-interpolation anyway? Have you tried the two techniques and compared. I'm interested maybe I'll try it now.

A great behaviour shot John. And its razor with the coupled converters.

Hi John,
A very interesting method - many thanks to yourself (and Nigel!) for sharing.
Your image is amazingly sharp with stacked converters too!

Nice one John.
Considering the set up used etc I would say its turned out really well.
Amazing what you can see sometimes when your hidden away.
Major.

A great behaviour shot, which I would be thrilled with. Would love to see more images from the serie.
