Introduction

Explain the theory behind controlling convergence.

Instruction

Select a print with distorted, converging lines and correct it by tilting the enlarger easel in the proper direction. The effect is more obvious when you correct a picture of a subject taken at fairly close range.

Make a combination print from a landscape negative with no clouds and a negative of clouds alone. Have your students apply instruction on converging lines and combination printing with the negatives they made for the last assignment. (Again you are only present for advice during this part of the class.)

Assignment

Have students expose a roll of fast black-and-white film with an adjustable camera. Have them expose the entire roll of film at a speed of ISO 800 taking pictures under dim lighting conditions.
