I was wondering if anybody know's a decent resource for information regarding using manual functions on a digital camera. I have recently bought an Olympus C4000 (superb value with recent price cut!) and I want to learn how to get more from its manual settings. All the books I have looked at for digital photography seem to mainly cover the image editing software not the actual taking of photographs, i.e. setting the aperture, shutter speed etc. I just want to grasp the fundamentals of what these controls achieve. Would I be better buying a normal photography book, which maybe more biased towards film photography or are there significant differences between the two and is there possibly a book geared more towards digital photography (taking the photos not editing them) available. Any ideas please?
