PhotoZoom Pro™ 2 is based on S-Spline XL: a renewed and improved version of our patented, self-adjusting, many times awarded S-Spline interpolation technology. As we did with S-Spline, our S-Spline XL technology again introduces a revolutionary breakthrough in digital image enlargement. It is able to render sharp and crisp clear image magnifications, perfectly focused, yet without the jagged edges, loss of detail or lack of photorealism that normally come with enlarging images.
