Below is an uncropped image of a Kaka at Pukaha Mount Bruce Wildlife
Centre, Masterton, New Zealand (without any post processing). This image was captured, hand-held, by the
full frame 24.6 megapixel Sony A900 camera. The full sized dimensions are
6048 pixels x 4032 pixels. The lens used was the Carl Zeiss F2.8 24-70mm,
focal length 70mm, ISO 200, exposure 1/125 second at F3.2.

This second Kaka image is a crop of the first image on this page and its
dimensions are 2448 pixels x 1630 pixels (approx 4 megapixels).
If the above image is printed at 150 pixels per inch (ppi), it will give a
print size of 16.3 inches x 10.9 inches. The ability to obtain a good 16 inch wide print from an image that is only
approximately 40% of the width and height of the
original, is one of the advantages of filming with a 24 megapixel camera.
Note that, in this example, the total area of the original image is
24,385,536 pixels (6048 pixels x 4032 pixels), and the total area of the
cropped image is 3,990,240 pixels (2448 pixels x 1630 pixels). Therefore,
the cropped image represents just 16.4 % of the total area of the original
image. To obtain a full-sized 6048 pixels x 4032 pixels image with the above
field of view, the photographer would need to use a 173mm telephoto lens.
The above images have been saved at a low quality and are displayed at a
relatively small size. Therefore, large prints of the above images look a
lot better and show a lot more detail than can be seen above.
