Giraffe at Wellington Zoo, New Zealand.
The above image was captured hand held with the full frame 24.6 megapixel Sony A900 camera, using the Sony 70-300 mm G SSM lens, with a focal length of 200 mm, and the original image size was 6048 pixels x 4032 pixels. If printed at 150 pixels per inch (ppi), the print width of an image that is 6048 pixels wide, is 40.32 inches (6048 pixels divided by 150 ppi). Note that the above image has been saved at a low quality and displayed at a relatively small size. Therefore, a 40 inch wide print looks a great deal better and shows a lot more detail.
To give you an appreciation of how much detail you can see in a big enlargement, below is a crop of just a small area of the above image.
Giraffe at Wellington Zoo, New Zealand.
The above crop (saved at a low quality) has an image size of 1358 pixels x 904 pixels, which represents only about 22% of the width and height of the original image. If printed at 150 pixels per inch, this would make a print of about 9 inches x 6 inches. The ability to obtain a good quality print of this size from a picture which is only a small part of the original image, 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 1,227,632 pixels (1358 pixels x 904 pixels). Therefore, the cropped image represents just 5.03% of the total area of the original image.
