Canon's EOS Utility is a very useful software solution that comes bundled with every EOS DSLR camera. It offers a range of functionality for photographers to control their camera remotely from a computer tethered with a USB or Firewire cable.
The Quick Control screen gives you instant access to the most common settings, all in one place. It’s a great way to quickly confirm or change settings while you’re shooting.
Peripheral Illumination Correction function maintains evenness of illumination from corner to corner in JPEG images (even when shooting wide open with a zoom lens)
