An introduction to photography An introduction to photography The goal of this class is to teach people the basics of photography, both from a technical and an artistic point of view. You won't be Ansel Adams by the end of this, but if you follow the entire course, you should gain a thorough understanding of how a camera works, how to avoid the most common mistakes, how to create technically good images and have an idea about the basics of composition. Lectures Prerequisites If you know which end of the camera to point at the subject, you have enough prerequisites for this. Syllabus Additional information This course is now complete, and all the lessons are online on the dedicated subreddit /r/photoclass. Teacher qualifications My name is Alexandre Buisse and I am slowly transitioning into full time photographer.
