Interpolation - making your images bigger
(Read the full article...)Cheryl Surry looks at the various options available that you can use to make bigger enlargements from your digital photographs. Whether you have a 2 or a 6 megapixel camera, making your images bigger is something you'll want to do from time to time, whether to print a large poster or to submit to an image library. The problem is, just like a 35mm negative is fixed in size at 24x36mm, a digital image is fixed by its pixel dimensions. Negatives are enlarged by projecting their image onto light sensitive paper, and the bigger you go, the lower the quality becomes. Digital images are no different, and whatever you do, you can't make them bigger without suffering some degradation in quality.
