Western Odonata Scans in Life

Images added 8 June 2004; text revised January 2007

These dragonflies are being scanned as they are collected, beginning 1997. An attempt is being made to acquire representatives of all Northwest species and their individual variation (primarily sex and age). All images are scanned on a Hewlett Packard ScanJet 4C/T with DeskScan II into Adobe PhotoShop 3.0 (upgraded to 5.5 in 2000) and saved as JPEG images at 300 dpi. Larger dragonflies are usually at 200-250%, damselflies at 400-500%, but there is much variation. All photographs copyrighted by Dennis Paulson, except those scanned by Kathy Biggs copyrighted by her.

I greatly appreciate the folks at the web site Digital Dragonflies for stimulating this project and for furnishing the technical advice on how to make it work. That site has abundant and beautiful scanned images of Odonata from central Texas.
