Making a Photograph – The Technical and the Creative

Exlore the technical and creative sides of fine art photography.

There’s no question about it; photography is very technical. There are many technical skills that must be mastered to become a proficient photographer. And they didn’t all just crop up when digital cameras came on the scene. Film cameras required a great deal of technical know-how also.

If you were taking a grand landscape photograph back in the days of film, a composition that had a very interesting foreground and a spectacular background, you had to know how to control your depth of field so that the foreground and the background and everything in between would be in focus. This required a technical knowledge of the three factors that affect sharpness; those being, focal distance (the distance from the camera to the object you’re focusing on), the focal length of the lens and the f-stop.

Exposure in the film era was perhaps even a little more intimidating. Your ISO was determined by your film and you selected that when you purchased it. But you had to set your shutter speed and your f-stop manually. Shutter speed wasn’t too hard to understand. If you decrease the length of time the shutter was open, you decrease the amount of light that passed through the lens by the same amount. A shutter speed of 1/30 of a second let twice as much light through the lens as 1/60 of a second. Pretty simple.

But f-stop didn’t make any sense at all. If your f-stop was f/8 and you wanted to double the amount of light coming through the lens, you set it to f/5.6. The amount of light was doubled but the number was smaller. And it wasn’t what you might intuitively have expected it to be, namely, f/4. It could be a bit baffling. And the only way to get a grasp on it was to memorize these weird numbers. With film you were stuck with manual exposure and there was no getting around it. With digital you can use one of the automatic exposure modes so you can get away without fully understanding this f/stop stuff. But it’s still best if you do.

digital-cameraThe coming of the digital camera introduced a whole new level of complexity. In the film age the camera was a simple mechanical device. You were responsible for doing practically everything – deciding where to focus, the shutter speed to use and the f-stop to use. The only role the camera played was to open the shutter for the precise length of time that you specified when you set the shutter speed.
