Photos.com offers subscription-based stock photography downloads. They are considered reliable, and feature a reasonable variety of images. However, for the professional who is looking to download photo objects for the purpose of building composites, there are better options available.
What Are Clipping Paths?
With photo images from Photos.com, the objects are intended to be laid in via "clipping paths"--an industry term for the edge around which one "cuts" to lift the image from its original source, and then lay it in to the new one. Unfortunately, photo images manipulated via clipping paths look pretty much as good as that picture you cut out of a magazine with safety scissors in second grade. If you've ever observed a Weekly World News cover, featuring a ridiculous pairing, like, say, Princess Diana sharing an ice cream cone with an Alien, and even your four-year old said, "Mom, that looks fake" you have witnessed the remarkable results that clipping paths deliver.
Opt for Alpha Channels
One very popular source for alpha channel photo objects is PhotoSpin.com. PhotoSpin, a recognized trend-setter in the image bank business, offers photo objects with either clipping paths or alpha channels-- and both at prices more affordable than their competitors. You can, of course, choose PhotoSpin.com even if you do insist on using clipping-paths. Just don't blame them when your four year old can't stop giggling at the result.
