Washington Park Arboretum with Canon G2 on Slik tripod. Hoya R72 Infrared pass filter, with occasional use of Tiffen .75x megaplus wide-angle converter. Raw, Tv mode, metered to get around f6.3-f8.0, most pictures bracketed 2/3 stop. Photoshop post-processing included auto levels, manual levels, saturation, and burn tool. Shutter speeds were very slow, usually between 6 and 15 seconds. Notice that some pictures exhibit center blooming worse than others due to the G2's hot mirror.
