Sumatran Tiger at Wellington Zoo, New Zealand : Panthera tigris sumatrae

The original image (with a size of 6048 pixels x 4032 pixels) was captured hand held with the full frame 24.6 megapixel Sony A900 camera, using the Sony 70-300 mm G SSM lens, at a focal length of 300mm. The above image is a crop, and has an image size of 3024 pixels x 2016 pixels, which is exactly half the width and height of the original image. Note that the above image has been saved at a low quality and is displayed at a relatively small size. Therefore, a 20 inch wide print of the above image looks a lot better and shows a lot more detail than can be seen above.

If the above image is printed at 150 pixels per inch (ppi), it will give a print size of 20.16 inches x 13.44 inches. The ability to obtain a large 20 inch wide print from an image that is only half 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 6,096,384 pixels (3024 pixels x 2016 pixels). Therefore, the cropped image represents just 25% of the total area of the original image.

Below is a reduced size copy of the original image, before making the cropped photograph shown above.

Note that the original size of the above image was 6048 pixels x 4032 pixels. If printed at 150 ppi, the print width of an image that is 6048 pixels wide, is 40.32 inches (6048 pixels divided by 150 ppi).

The above image has been saved at a low quality and is displayed at a relatively small size. Therefore, a 40 inch wide print of the above image looks a lot better and shows a great deal more detail than can be seen in the above image.
