DearWebby is actually Helmut Morscher, the CEO of Webby, inc.

Originally the "Tech Support Pits" were reports of the funniest tech support incidents, but over the years the column gradually shifted to answering tech support questions put forward by the readers of the Dear Webby Humor Letter.

This collection of computer and web advice was started partly because readers demanded an archive, and partly because some questions were asked again and again. Each page has a different day's Tech Support Pits column.

Have FUN!

Tech Support Pits:
From Sandy=== Dear Webby, I finally got myself a scanner. What is the best DPI resolution to use? Thanks S Dear Sandy That depends on what you are scanning. If you are scanning old pictures that may need some fixing up, use the highest resolution possible. That gives you more pixels to work with. If you have reasonably good pictures and just want to use them on a web page, use medium resolution. If you are scanning text and want to run it through an OCR program to convert it to machine usable text, use medium resoluton in grey scale or black and white. High resolution may overload your OCR program and even if it doesn't, it is going to seriously slow it down and it will introduce more errors than medium resolution. If you are scanning text for archiving, use low resolution in grey scale. That compresses the best. However, if you are going to paste, for example, 12 invoices onto a page, and then reduce the page, use medium resolution grey scale for scanning, paste them all together, increase contrast 20% and then reduce the size of the page. Have FUN Dear Webby
