Overview
Exposure is controlled through aperture, shutter time, and sensor sensitivity, each affecting the image differently. Focal length changes framing and perspective; depth of field depends on several factors. Composition can use leading lines, negative space, and visual balance. Editing should preserve the intended truthfulness of documentary work and be disclosed where needed. Consent, privacy, cultural context, and safe access matter, particularly when images depict vulnerable people or private spaces.
Core ideas
Learn exposure relationships, focal length, depth of field, composition, and responsible image editing.
Try it
Photograph a still life of three household objects in window light, changing only viewpoint between frames. Avoid photographing people without permission.
Study pathways
Learning options include photography programs, workshops, apprenticeships, and independent portfolios. Commercial work involves contracts, copyright, model releases, and local privacy laws; consult relevant authorities and professional associations.
