I was able to get a good close-up shot of a leopard when I really couldn't see it with the naked eye or even through the 12x optical zoom lens. This instructable will teach you how to do it.
Addendum made on Feb 24: Someone pointed out that the animal in the picture is most likely a cheetah, not a leopard. Nevertheless, the technique used here is still applicable.
Step 1: Shoot the Image and Crop Later
In the first image on this page you can easily spot the leopard but imagine trying to see the animal when this image is shrunk to a 2-inch screen. The second photo shows what it looks like in the viewfinder. What I did was simply point my camera in the direction they said it was in and zoomed in as much as I could. I took the shot at max resolution (7 MB).
Then I reviewed the image in the viewfinder and digitally zoomed in as much as I could. After panning around a bit, the leopard was as plain as day. Others in van were amazed when they looked at the zoomed in image in my viewfinder. They started using the same trick. It's ironic that the one person with the $5000 camera with a huge zoom lens couldn't do this because her camera didn't have the digital zooming capability.
My camera is a Panasonic FZ8. It has 12x zoom and a capability of 7 MB resolution. It only cost me $300.
I use GIMP on a Linux box to do things like cropping and scaling. At home I was able to view the image in GIMP on a 22 inch monitor and crop just the leopard.
The first image shown here has been scaled to 600x450 pixels for this instructable. You can see the original version (2560x1920) at http://www.datasink.com/images/africa/leopard_fullsize.JPG.
The very small image on this page is only 180x135. The final zoomed-in image is 804x500.
