Photo Techniques: Macro Images & Image Post Processing.

A macro image of President Grant converted to false colors using a Nik Color Efex Pro 3 “Infrared Thermal Image” filter. Notice the “The United States of America” micro-print.

Winter Nature in New Jersey.

Great Blue Heron and a pair of Mallard Ducks in the pond at the nearby Sourland Mountain Preserve. I guess they decided to spend the winter here rather than in Florida.  Some years this pond freezes over.

Currency & Stamps: Micro-print.

One method I use to test the resolution of cameras and lenses is to see well the combinations perform. The US $50 bill has “The United States of America” printed using very small letters. A copy machine would have difficulty resolving something this small.

Gone to see Florida 2007 Road Trip Day 7: Dawn over Tampa Bay.

I stayed at the Historic Vinoy Hotel in St. Petersburg. This was my last day in Florida, and I took a series of images of the dawn colors over Tampa Bay from my balcony. The Vinoy Hotel is a great place to stay and I want to return.
