Biography - I have spent most of my working life as a research scientist - first as biochemist, and now a pharmacologist working in the Pulmonary Division of Philadelphia's Temple University Hospital.
     My interest in photography goes back to childhood when my father let me click a few pictures with his Kodak Retina camera on family vacations.  It became more serious when I purchased my first SLR (a Pentax) and joined the Delaware County Camera Club in the early 80's.  I also bought a computer (a Commodore 64) about that time, but it never occurred to me that computers and photography might someday coalesce into one single endeavor.  I did marvel at my computer's immense 64K of RAM - more memory than I would ever need, I thought!
      Yet, by 1995, my beloved Commodore was on the verge of becoming an antique, and I bought my first PC - a Pentium 90.  For 6 months or so, I had the fastest computer on the block!  This, in turn, led to my growing interest in digital imaging, which continues to this day.   I presently have Canon Powershot G5 and Nikon D80 cameras, plus a Microtek 4700 flatbed scanner, Dimage Elite 5400II film scanner, and an Epson 1280 color printer.  I continue to use a variety of imaging/graphics programs: Photoshop CS4 and plug-ins; Photomatix (for HDR); Bryce and Poser (for 3D work); plus Ultrafractal, Fractint and Tierazon for fractal designs.
