Filters help minimize glare and reflections, enhance colors, reduce the light coming into the lens, and more.
In the first seminar about filtration for photographers we looked at the various types of filters available, how some of them are made and demonstrated what effects filters had on both colour and panchromatic B&W photographic films.
In this seminar we will do a little revision on what was covered previously to refresh people’s memories and to help people, who didn’t attend the previous session, come up to speed in preparation for this session.
The new topics that will be covered are the testing necessary to establish a speed point for each of the filters. Not all films are sensitized to record the colours of subjects the same way.
We’ll show some of the differences in some common films response.
