Sharpness and blur from technique and optics. Causes and solutions, shooting technique, getting full sharpness from any camera.
Introduction and overview of making sharp images.
How a lens blurs when out of focus is a Big Deal.
Blur from optical behavior or subject-related issue.
Sharpness loss by focusing or zone of sharp focus.
Sharpness loss by camera or support or technique.
Digital capture technology is discrete, and not the same as film.
Evenness of illumination, color shading, digital sensor effects, ray angle.
