Velvia is very saturated and punchy, so it must be used like a heavy weapon--deliberately and on an intended target, otherwise you'll get sheets of garrish looking images and feel dismayed. It is absolutely great for sunsets, reds, yellows, blues, but makes green jump like electricity. I would highly recommend against it for people as well, since it makes the skin look unhealthy. That being said, when used correctly, it's a truly remarkable film. Go experiment in some flattish/low contrast lighting and see what you get. It has a super narrow exposure, so be absolutely certain of your meter. I'm talking sometimes even a half stop is the difference between breathtaking and overexposed.
