so, do you have the image on a disk? A photograph? Let''s say that it is Great Aunt Edna''s 90th birthday. What better way to show you care than to give her a life-size environmentalgroup printout of herself! To ensure that every wrinkle prints out clean and crisp, we need the full-size image resolution to be 50 dpi (Dots Per Inch). That means that when we blow up Aunt Edna''s best mug shot from a 3"w x 5"h photo to a 36"w x 60"h banner the scan has to be done at 600 dpi. The nifty little equation we use for figuring this out requires environmentalgroup some algebra skills on your part but works wonders when trying to determine the scan resolution of your image. Photographic Prints and Negatives: How photographs and negatives scan depends on the quality of the original. If the image is blurry there is little that environmentalgroup can be done to improve the sharpness. If the photograph is too dark or too light, or the color is not great, the scan can be manipulated to some extent environmentalgroup and improvements can be made. A negative will always contain more detail in the shadow and highlight areas than a photograph produced from it. Whenever possible, please provide the negative along with a photographic print that appears less than environmentalgroup perfect. Transparencies: 35mm slides, 2 1/4", 4" x 5" and

Databases are optimized to search for exact words and phrases, and they tend to respond very slowly otherwise. So if a searcher wants to find "sheepskin" environmentalgroup or "shearling" in the same search, databases will tend to do two searches and then merge the results. Full text indexes are designed to store these words together, environmentalgroup so a search engine can perform these environmentalgroup kinds of searches efficiently and return quickly. In addition to the time, searching databases requires additional back-end and server resources. By storing a search index on a separate server and searching that rather than the live data, a text search engine can perform queries without additional demands on the database itself.
