with theory, tips, examples and technical solutions.
By Dr J Floor Anthoni (1997-2005) 
www.seafriends.org.nz/phgraph/index.htm


This is an extensive and essential course in underwater photography, bringing together in one place all the known theory, extensive hands-on experience, many examples, tips and technical solutions, without going into commercial details. Taking photos under water is one of the most difficult branches of photography because the underwater world has such strange optical properties and is rather taxing on the photographer himself. By mastering the advice provided in this large primer, you will enhance your chances of success considerably, resulting in more enjoyment. Why re-invent the wheel? Welcome and good Luck!
History
Important dates in the history of underwater photography. (on this page)
Introduction
Why would you like to take pictures under water? What knowledge, experience and skills do you need? What equipment? How do you manage your precious resources? How do weather, waves and wind affect your results? - and more general information. (12 pages)
Film and lens
What kind of film should you choose or are you going digital? How can images be manipulated and saved for posterity? What kind of lens to use? What effects to expect? (10 pages)
Water and light
How is the quality of the sunlight affected by the water and how does this affect under water photography? What are the techniques to capture both colour and under water mood? How to reduce scatter? Which are the best camera angles? (10 pages)
Mixed light
A help light such as a strobe or a movie light is often necessary to overcome the limitations of ambient light. This mixed lighting is often misunderstood, resulting in poor results. How can we use the colourful light of the strobe without destroying the underwater atmosphere afforded by ambient light? How to control your strobe light?  (11 pages)
Macro
Theory, technique and practice of macrophotography, enlarging the miniature world and getting really close. Aquarium photography. (12 pages)
Opportunities
Recognise the opportunities offered by the topography of the environment. How should you behave to maximise your luck? How to organise your diving.?(11 pages)
Nikonos cameras
The Nikonos RS camera has changed underwater photography forever and still is an awesome tool. Try to understand what you need in an underwater camera and how to use it. (9 pages)
Tips&Tricks
A look at photographic gear and how to adapt it to your needs. O-rings, brackets, connectors, cables, lights. Don't be afraid to make your own. (in prep)
Digital Darkroom
part2
part3
Digital computer techniques have given us the sophisticated tools to make better images after shooting the film. This chapter teaches you the ins and outs of colour theory, colour spaces, digital photo processing, scanning, cleaning up, adapting contrast and tone, sharpening and blurring, compacting your images and much more. You will disadvantage yourself by missing out. (32 pages in 3 parts)
movie&video
In addition to a thorough understanding of underwater photography as explained above, the movie maker must master a number of other faculties. Making a movie does not consist of just taking moving pictures. (4 pages)
