I have been shooting with analog SLR cameras for decades and had a good understanding of exposure, shutter speed and ISO. However, reproducing the same results with a DSLR was a challenge. The class teaches you how to put your camera in the optimal settings to control your camera manually with the greatest ease. If you want to learn what many of those menues and buttons do, this is a great class. Carlos, our instructor, was great! Upgrading to the 4 week program and giving the Digital 101 to my uncle for Xmas.
