| The book is printed in hardcover with an attractive layout and cover, but the illustrations are terribly muddy and unsharp. |
| Images formed by the lens at large apertures are therefore unsharp but get sharper at smaller apertures. |
| The effect of the unsharp mask is very subtle, but makes a significant improvement to the overall appearance of the image. |
| If you want to retouch photos or apply unsharp masks and such, you need Gimp. |
| One handed shooting is lazy and you will always run the risk of unsharp shots! |
| You may notice that the entire image has the unsharp mask applied to it beforehand. |
