Equipment is very much secondary to me when making photographs, but it is important. Almost anything will do if I understand how to use it effectively. I've been using a spot meter for years until just recently when I bought a metering prism for the Pentax 67. At first, it seemed to eat batteries within minutes, and I thought I'd have to return it to KEH, but I bought fresh batteries and they've not discharged nor failed. This is an image from the first roll of film I've used metering with the prism. I'm pretty happy with what turned out in difficult lighting. It's a photograph I made on the way home from a very satisfying visit to a gallery that liked the box of prints I showed. Where that will lead is unknown, but it was a good experience.
