1) Go for color. Black-and-white photos are beautiful, but most magazines publish them sparingly. Your best bet is to use vibrant but natural-looking color—go easy on the saturation levels. Though there is such thing as too subtle: High-key, white-on-white images, striking as they are, will let whatever's printed on the page behind show through. Conversely, images with a lot of black, brown, and gray often become muddy in the printing process.
