Photographic Practice: Studio Workshops (Studio)

In this blog post I shall introduce the start of the studio workshops we had for the studio project for Photographic Practice. This will be the first of three blog posts on my studio workshops.

Over the course of this project we had to attend studio workshops, to introduce the class to different photographic equipment used in the studio. The first workshop was introducing the class to a variety of lenses that can be used on the college Canon DSLR’s and our own Canon DSLR’s. There are different classifications of lenses, the two main classification of lenses are prime lenses and zoom lenses. Prime lenses have a fixed focal length, which means to get closer to your subject requires you to physically move closer or use a teleconverter. Zoom lenses have a variable focal length, so you can change the focal length of the lens without physically moving (this will change the field of view as well).

The second workshop introduced the class to the concept of Photographic Stops. A Photographic Stop is a measure of exposure in relations to how much light you’re letting into the camera. Photographic stops depends on the camera’s shutter speed, the aperture and the ISO (on the film or the sensor sensitivity). We use photographic stops to help us determine studio flash power alongside the camera’s exposure. We keep the shutter speed to 1/125th to correctly sync with the flashes and have the ISO set to 100, to get the best quality of images. So the two variables we can change are the Aperture on the lens and the power of the studio flashes themselves. With a light meter we can determine where to set our aperture. We also learnt about lighting ratios 1 to 1 is where both Key and Fill light emit the same power. 2:1 is the lighting ratio in where the fill light half the power of the key light. 4:1 is the light ratio in where the fill light is a quarter of the power of the key light.

 

Overall the workshops have been useful and challenging. Though I enjoy shooting in the studio these workshops have broadened my vocabulary when talking about studio lighting set-ups, and choosing better suited photographic equipment for different scenarios.
