For years I worked with 35mm and medium format film cameras.  Nikon was my body of choice for 35mm film photography, and I used several different models.  I also used a Pentax67 medium format film camera which provided many years of good service and wonderful transparencies for large-sized prints.  In 2006 I moved into digital photography with the acquisition of my first Nikon digital SLR.  These days, I rarely use film, and when I do, it is for special purpose situations only.  Digital is my everyday photo format.

I utilize lenses ranging from 12mm super-wide angle to 500mm telephoto.  Most are Nikkor lenses with a couple of pro-quality Tokina ATX lenses in the mix.  Some are newer models, some are quite old.  I occasionally use a 1.4 teleconverter or extension tubes to extend the capabilities of some of the lenses.  For close-up work, I use a Nikkor 105mm micro (close-up) lens.  Shooting digital, I use very few filters.  In fact, the only filter I use on a frequent basis, and depending on the situation, is a polarizer to reduce glare.  

I estimate 90% of my photos are taken with my camera either mounted securely on a tripod or, when need be, some other make-shift support.  My tripod is a very durable and sturdy model made by Gitzo.  It is topped off with an Arca-Swiss B1 ball-style tripod head with a quick release camera/lens mount.

While my camera bodies and lenses are auto-focus capable, I usually do not use autofocus when working in the field.  Focusing manually works best for me when shooting landscapes and for close-up work.  For most wildlife and avian photography, I switch to auto-focus. 

I carry my equipment in a photo backpack.  If going light with only a single body and a couple of lenses, I often use a smaller day pack or shoulder bag.  My ever-present tripod is slung over my shoulder or secured to my pack. 

Most of my photos are captured in RAW format.  Photoshop is used for post-processing images to adjust contrast, minor color adjustment and sharpness.  No other digital manipulation is used.
