After posting a few comments and receiving immediate answers and solutions, I´ve become a subscriber of this very enjoyable forum. Considering that I don´t voluntarily sit in front of a screen during my spare time, this forum is the most pleasant exception to my rule I can imagine.
I am a biologist and live in Guatemala. I started photographing over 20 years ago, to illustrate research projects and later, as a teacher, to have visual material for the courses I taught. I use a Nikon F4 and a 300 mm f/2.8 for most of my wildlife photos, and if I need to get closer, I get up earlier and use a thermos of coffee and a blind.
I started doing B&W about 12 years ago, just about when I quit my teaching job and began working in the pigment industry. After looking at colors all day long, I really enjoyed and looked forward to the silent glow of B&W. After making the first print from a medium format negative, I bought my first Rolleiflex (I paid US$ 9.25 for it at a local Christmas Bazaar; the guy who sold it to me, sold it for decorative purposes, since they don´t make B&W film anymore), and a year later I bought an 8x10.
I usually make images during the dry season and accumulate negatives and print them during the worst part of the rainy season.
I just finished my house and built a darkroom (coffeemaker, refrigerator and stereo) and started working on a portfolio of rare, bizarre and endangered plants of Guatemala. I look forward, now that I found a place with answers to my questions, to start printing my large negatives using alternative printing materials.
