My Early Photography

Most of my photographic career, if you will, was in the days of film. When I worked at the college paper and yearbook it was all black and white. I have liked B&W film because it dosn't show everything that color does. It seemed more artistic.

One of the things about black & white film, particularly Tri-X, is that it had a good exposure latitude. That is, in the proper exposure, it would use all the values from black to white, as in this photo. Note: unfortunately any example I use are taken from digital originals, this one included. I will have this photo and others in my Google Photos section. This one may look different as it will have another effect added to it, film grain, to more simulate the look of Tri-X.

During those days Tri-X was the film of choice by photojournalists. It had lots of exposure latitude. It could be pushe; underexposed and over developed and you could get a decent print out of it. It didn't get too grainy, the photogrphers worst enemy.

As time went on I understood more about things like reciprocity failure; when the relationship between the shutter speed and apeture don't deliver a good exposure. Usually in low light situations, if I remember correctly.

Generally the faster the film, or higher the ASA number, the grainier the picture. The lower ASA numbers were usually the chrome films, or slides. The lowest being 25, which was known for it's fine grain. Reciprocity failure was an issue if you tried to do longer exposeres in low light with the chrome films. Although it could happen withhigher ASA print films as well.

I've been thinking about how to develope this photography blog and I thought a few links to info on film cameras might be helpful. If I find any I will let you know and include them here somewhere on this page.
