Today we were taught how to use Large format film cameras, and the preparation that comes along with it. We were introduced to a number of example images, what the camera is usually used for and the equations used to figure out how much lighting is needed in relativity to the subject’s distance from the source. It can be explained with a few mathematical equations such as the Inverse Square Theory:
This workshops was extremely helpful in the light that the skills learnt from it can be applied to any variety of photography, studio or otherwise . It’s taught me that the preparation for a photograph is absolutely key to take a successful image. I set up the camera with my classmate Zen, who took his picture first, accidentally left the lens clip on while taking his set up shot. Therefore, when it was my turn it was of utmost importance that I took every measure to make sure my photograph was set up and taken properly.
This is the image I took on the large format:
We were also taught the mathematics behind extending the bellows of the camera, as well as taking into account the exposure compensation or magnification factor. I wasn’t oo sure about the bellows extension part after the workshop, so decided to find a better understanding online. I was taken to this forum where it was summed well, ‘the exposure reading from the light meter will only be accurate when the camera is focused at infinity. To focus on objects closer to the camera the lens must be moved farther from the film plane, and less light falls on the film. So additional exposure needs to be provided to make up for this light loss. The farther the bellows is extended, the more compensation is required.’ – http://www.apug.org/forum/index.php?threads/bellows-extension.43275/
