Back to Basics 2: Understanding and using Shutter and Aperture creatively
Shutter and aperture control exposure. More importantly, both have very creative uses. The shutter controls the length of time the image sensor is exposed to light. High shutter speeds stop motion, slow ones blur motion. Large apertures yield shallow depth of field while small apertures let everything to be in focus from back to front. Shutter speeds are expressed in whole or fractions of a second. Aperture openings, however, are described by f-stops and confuse many beginning photographers. All camera exposure modes use various combinations of shutter and aperture. Jim Morgenthaler will help you understand how these modes work and how to choose the right one for each shooting situation. Program mode is a good choice for rapidly changing scenes. Aperture mode allows you to choose how much of your image is in focus (Depth Of Field). Shutter mode allows you to intentionally blur or stop action. Manual mode is used for fireworks, lightning shots, and static scenes. Even Scene modes can be useful at times when you understand how they make use of shutter and aperture! It does not matter how you achieve the correct exposure. All that matters is whether it’s a good photograph or not!

What we're about

The Southeastern Photographic Society (SPS) was formed by photography students at the Callanwolde Fine Arts Center to help its members learn the skills for capturing great images and sharing them with others. The society has been serving the photographic community since 1976, now with well over 250 annualy paid members.

Each month SPS hosts a competition and lecture/presentation on the first Friday. Competition themes vary each month with the goal being to encourage members to shoot outside their "comfort zone".

On the 4th Tuesday of the month SPS hosts their popular member "Learn Shops"; informal lectures/presentations from club members to help teach each other a variety of photographic skills, from lighting and composition to Photoshop and Lightroom.

The club tries to arrange for field trips throughout the month. These field trips are designed around upcoming photography themes but also around events that take place in the local area. Sometimes we just like to get out with others and share our knowledge.

In order to enter images into competition (digital or prints) you must first be a fully paid SPS member. Annual dues are $30 for individuals and $40 for households, due each January.
