“PhotoCalc offers handy calculations for professional or hobbyist photographers working in the studio or in the field. PhotoCalc provides exposure reciprocation, depth of field and hyper-focal distance calculations, and flash exposure calculations.” I’m still not quite “there yet” for this level of calculating but it looks really interesting. I’m saving this for future reference if/when I get hardcore enough to warrant it.
“How Much Does It Buy? is a currency converter for those of us who aren’t day traders.” Entertaining.
