Macro pictures look cool. Most people don't know how to take them well and are easily impressed by them. Good pictures of small parts can make all the difference in an ebay auction or a craigslist posting. As a mad scientist, I often use it for taking pictures of test results and using it to see details too small to see with the naked eye. Doing a quick measurement of the tap on my screen, my 7 megapixel camera gives me about an 8x magnification when viewed on the screen at full size. For more detail, you need to get into microscopy. That instructable will be coming along soon.
If a picture is worth a thousand words, a good macro picture must be worth&the one thousand and sixty-nine words here.
Since the small photos here don't really do it justice, I have the full size images here:http://www.bloomautomatic.com/3546.jpghttp://www.bloomautomatic.com/3547.jpghttp://www.bloomautomatic.com/3549.jpghttp://www.bloomautomatic.com/3550.jpg
