Ever wonder why products in catalogs are always shown without backgrounds? Even majority of clothing models are typically shown on plain white.
Without distracting elements hovering behind the product, a customer is free to see the product itself. Your customers’ eyes will instantly be drawn straight to the product — exactly where you want it to go. The product looks cleaner, especially without the distracting noise of the background. Also, depending on the product, a subtle drop shadow may add more depth to a product picture.

If you take the additional time to set up a product shot, it really pays off in the end. Not only will it need less work done in photoshop, but it will give your website a complete and professional look.
