Sorry but I must take exception with the First point:
“Digital cameras don’t like nature Pixels don’t treat all objects equally. One of the worst things to photograph with a digital camera is a tree. If your camera can capture a million pixels and your subject tree contains a few hundred thousand leaves, you’ll end up with only three or four pixels per leaf, and the whole image will smear together in a big, gummy mess.The same goes for lush lawns, bountiful gardens, distant mountains, hairy surfaces, and just about any other subject with scads of intricate details. For the best results, shoot only clearly defined subjects that have smooth, distinct outlines. People photograph well, as do cars, buildings, furniture, and most man-made objects. In short, stick to obvious foreground subjects that stand out sharply from their backgrounds.”

If you are using a point-and-shoot, maybe, but I have a number of images shot with a DSLR that disprove the first point. Please feel free to visit my blog and check the images out as well as the links to the various sites that I have my images on. Some of the images are scanned film, but a lot are digital images and you’ll see quite a few trees.

Best regards,
