6) "Careful" A very important thing you'll need for digital photography is Photoshop. One thing the digital camera has done is remove the darkroom out the equation, something you need if you want professional images. Ansel Adams' work was half spent in the darkroom. The new technology's darkroom is Photoshop. You must learn to use this program if you want to greatly enhance your images and, also, to manipulate the story you want to tell. Maxed out the ISO on this 1600... ouch. The key to changing this image was to have a second shot without people in it, just cut and paste in Photoshop.
