I teach photography at the University of Malawi. I have a class of graphic designers coming up, that I will teach a little photography in 12 lessons. The starting level is low. The available equipment minimal, some have no more than a camera-phone available. I do a practical training: make photos. A headshot, an environmental portrait, a product photo, an architecture photo etc. I can order a few books for the library. Everything we have there is out of date. I need a book on general photography, one on light, one on photoshop, one on composition. Which books (in English) would be the best for this target group?
