Some Equipment Specs and Data
and
handy photography information references

     Occasionally I have need of some equipment spec or manual. In the case of older or used equipment without original documentation, the info was often difficult or impossible to find, even on the web. I began collecting files and web links relating to my own equipment, but the web links would too often disappear. In an effort to solve this problem and have the data available to me anywhere I had an internet connection, I began grabbing the data and saving it online. I thought it might be useful to others as well, so here it is. Keep in mind this only covers equipment I happen to have, but in the case of older items in particular, it may prove useful to some of you.

     For equipment not listed here, I can recommend these sites with lots of equipment, reviews, specs and images, as well as "archives" of discontinued items.

How to Select a Graduated Filter

To determine which strength filter to use, meter the foreground, then meter the sky, calculate the difference in f-stops between the two areas (e.g. 3 stops). Whatever the difference, use a grad filter that is 1 STOP LESS THAN THE DIFFERENCE (e.g. 2 stops) or your skies will look too dark and phony.

Full stops
1/3 stops

example- f/4 is two stops diff. to f/8
