Welcome to ClarkVision.com.
The purpose of the site is to present information. It is not a commercial business, nor is it political. The information presented on this site concerns hobby-related activities of photography, amateur astronomy, and the important aspects of vision, as vision is a key component of photography, astronomy, and observing our world every day.
This site is cookie free, and only contains static html web pages, no java, java script, or php is used. But all access is logged for security.
The photographic images on this site results from film and digital processes designed to capture as much detail in the original scene as possible. The reason for this effort is to create images that are "like being there." Digital processing of images provides for more precise control over contrast, color, and the printing process than with traditional darkroom wet chemistry methods. Our best images are obtained on large format film and scanned on a high end drum scanner and output on a laser film writer direct to photographic paper (or film). This process preserves sharpness not possible with normal enlarging methods.
While we will sell images you see on this site, we are not in the business of selling at this time. Photography as an enjoyable art form and we are not trying to make a living from it. However, if you see something you really like, contact us by email and we'll discuss making a print. (Large laser prints are very expensive.)
