It is mid-May and the Iris germanica<\/i> from my mother’s collection is once again in full bloom and suitable for visual exploration. Botanically, an Iris is a perfect flower with three petals, trichrome yellow bearded sepals. Each year the question becomes, how to best showcase the purple, yellow, and white flower without presenting a simple still life cliche.<\/p>\n

Participants in Experience Photography workshops have become familiar with my discourse on the creative significance of depth-of-field. Among other things, digital single lens reflex (DSLR) cameras are adjustable to allow the creative control of exposure and depth-of-field. Unfortunately, this less-understood or misunderstood aspect of photography is applicable to every aspect of that visual art.<\/p>\n

Non-adjustable cameras – such as point-and-shoot, disposable, and camera phones – do not provide for the creative use of depth of field. The lens aperture, lens focal length, and distance to subject all affect the depth-of-field. Non-adjustable cameras deny the use of one or more of these tools and thereby reduce the creative control provided to the photographer.<\/p>\n

As a photographer, if you cannot discern the difference between the top and bottom photograph, then depth-of-field may be of no concern. If you do not care to know the difference<\/b> then, based on current technology, you should not be considered as a serious participant in that visual art.<\/p>\n
