Cambridge in Colour has a series of tutorials on digitial photography. Frankly digitial photography is not that much easier than traditional film photography, as you need to take care about the exposure, noise level, colour, file formats etc. However digitial does increase the control over traditional. Sometimes I take bad quality photos, and learning something in tutorials should able to save time by increasing of chances taking good photos:
Photography is going through an exciting and often controversial transition period as many traditional film photographers are beginning to explore the new capabilities made possible with digital cameras. Traditional aspects such as the fundamental techniques and lens equipment have remained the same, however others are markedly different. Photographers using digital equipment now have previously unattainable control over noise levels, dynamic range and color accuracy. This is an exciting time to get involved with photography and digital imaging.
Imaging and digital photography software changes routinely, so these tutorials aim to emphasis key concepts over specific step by step procedures. They are also designed to be general enough that nearly any common editing software can be used, unless otherwise stated.
Some of the tutorials are quite advanced but they are pretty good read.
