How do you take picture of products at home? Home made light box (we'll cover this topic in another thread) plus day light bulb?
What kind of daylight bulb? The one purchased from Walmart or Homedepot ('the swirl bulb'). Those bulbs are not ideal daylight bulb. Your picture will not have WHITE background.
Here is the Color temperature hue scale.
Real daylight color temprature is between 5000-5600K. So you need to purchase light bulb designed for studio--daylight fluorescent bulb with color temprature between 5000-5600K. The color temprature must be marked on the bulb.
The price of the bulb is between $5-$29 each, depends on the brand. Search eBay or Amazon.com you'll find one.
