Step Interpolation is a completely different way of increasing the size of your images. Rather than using one of the five Interpolation options from inside the Image Size Dialog box, the step interpolation method involves gradually increasing image size by small percentages. The percentage that’s usually settled for is 10%.

Step Interpolation isn’t always the best means of interpolation, as it’s a longer and more painstaking process than using the Bicubic sharpener or the Bicubic smoother.
