www.kenrockwell.com Technical Reviews - Ken Rockwell provides one of the most useful independent reviews of lenses that I have found so far. Practical and informative for buying decisions, and laced with dry humour.
www.scottkelby.com Photoshop guru Scott Kelby has produced several books on the theme of "Photoshop for Digital Photography". I enjoy his style and have found the techniques very useful. His unique humour leaps from each written paragraph, and his photo gallery makes me want to give up photography in shame.
www.dpreview.com The forums section of this site provides valuable comments on a wide gamut of subjects, and is organised by your choice of camera or more general subject.
www.photoanswers.co.uk Is a good UK photography mangazine site that I find has some useful video tutorials on adjusting your images in Photoshop. Simple stuff, but useful to the beginner.
