Was slightly kidding. Could have been what I was shooting at THAT week.... all the attention I'm getting here is great! I think of a Normal 50mm lens on a 24x36 format as a default and would hope to interpolate with other focal lengths. Other formats too but I don't think so much about that because I don't use other formats much at all for 2.5 years. Right now on my camera I have a 45mm Nikkor P in silver with its odd silver lens shade. Its been on there for a few days now. Its set at A and 5.6 100th of a second default top shutter speed with auto iso which means a lot of exposure will be done at that speed unless its real dark. Lowest ISO setting is 500. So lots of exposure done at that iso even in sunny 16 situations. That's my world! Some Other defaults: Tri x with D 76 1:1 8x10 inch or 8.5x11 inch paper. Epson printers Domke strap Clean underwear (briefs) washed in Clorox bleach. Dansko clogs. My Tilley hat is a Patagonia My single malt is Earl Grey. My favorite camera company is Leica.
