Wellington City as seen from the top of Mount Victoria, looking towards the
Te Papa Museum.
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 210mm, 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 (saved at a
low quality) of just a small area of the above image. You can even read the
name "Wellesley" on the boat in the enlarged image!
Boat "Wellesley" on the Wellington Waterfront.
The above image is a crop from the photograph at the top of this page, that
was taken (about 4-5 kilometres away from the boat) from the top of Mount Victoria in Wellington City, New Zealand. This
has a size of 1581 pixels x 634 pixels, but in order to fit it on this web
page, it has been reduced in size in
the above photograph to
870 pixels x 349 pixels. Therefore, this crop represents 26.1% of the width of
the full sized image of 6048 pixels. When this crop is printed at 150 ppi
(pixels per inch), the print width is 10.5 inches (1581 pixels divided by ppi of 150).
To obtain a full-sized 6048 pixels x 4032 pixels image with the above field
of view, the photographer would need to use a 800mm telephoto lens.
The ability to obtain a good quality print of
this size, when the cropped image is a small part of the original, is
one of the advantages of filming with a 24 megapixel camera.
It is clear from the clarity and quality of the 10.5 inch wide print from
the above cropped image, that it would be possible to obtain a very good
quality 40 inch wide print at 150 ppi of the whole image.
Note that, if the objective had
been to capture just an image of the boat "Wellesley", then a clearer
picture than displayed above, could have been obtained using, say, a
telephoto lens with a 500mm focal length. Alternatively, the image could
have been taken a lot closer to the boat as shown here.
However, the cropped image shows
the amount of detail that you could expect to obtain, assuming that you make
a big enlargement (say, 40 inches wide) of the image at the top of this

To obtain the best appreciation of the quality of the images on this site,
they should be displayed at a relatively small size, because each image has
been reduced in size to a maximum width of only 870 pixels, from the
original width of at least 4900 pixels (or 6000 pixels from my full frame
cameras). In addition, the images have been saved at a low quality setting.
