This image has been shrunk to 18% of original linear size and
compressed for this webpage.
The original image was 1600x1200 pixels which represents 1.92 mega-pixels - requiring 5.76 megabytes before compression by the A40 digital camera. This particular image downloaded from the A40 as a 844,301 byte jpeg file - which is much too large a file size for webpage use. The picture was taken 15:45 BST late October in Surrey England - looking due south catching the late low sun - and at maximum optical zoom. Electric power cables can be seen against the sky. |
