		<description><![CDATA[It’s been f ive years since I tested the resolution of the Canon 10D digital SLR against that of f ilm. At that time, the 10D was about $1,500 for the body, and I found that film offered about twice the resolution of digital, depending on the lens. Times have changed. I just had the pleasure of testing the new Canon 50D against the same f ilm, the same lens, and the same resolution chart. The results were impressive. The film camera was a Canon 630 with a Canon 50mm ƒ/1.8 lens; the digital camera was a Canon 50D, hot off  <a href="http://phototechmag.com/digital-film-and-resolution-a-test/">Read more &#187;</a>]]></description>

		<description><![CDATA[When printing black-and-white on variable contrast paper with a color-head enlarger, the usual tactic is to make a single exposure through a discrete filter, such as 20M (magenta) or 50Y (yellow). That specific filter is selected to afford good overall contrast to the print, which may then be fine-tuned by dodging or burning selected portions of the image. An alternative technique—so-called split-filter printing—is to expose a print twice, once through an intensely magenta filter and then through a strong yellow filter (or vice-versa). With this approach the relative times for the two exposures are adjusted to create a print of the  <a href="http://phototechmag.com/does-printing-with-both-high-contrast-and-low-contrast-filters-create-a-richer-print/">Read more &#187;</a>]]></description>

		<description><![CDATA[Canon and Nikon both offer GPS units for both stills and videos. What are the practical aspects of using these units during shooting and what uses and considerations are there for GPS data? Introduction Both Canon and Nikon offer GPS units that can be connected to their respective brand DSLR cameras, with recent-models having built-in menu support with recording options. With both brands, the GPS units are add-on devices that are designed to mount in the hot-shoe of the camera, though both can be mounted to a belt or otherwise with a cable. With the Nikon GP-1 a cable is  <a href="http://phototechmag.com/field-test-gps-units-from-canon-nikon/">Read more &#187;</a>]]></description>
