STG is designed for QUALITY!
STG uses an advanced blending algorithm that was carefully designed to retain
sharpness ,color , and contrast throughout the image.
Other programs do simple alpha blends, or clone, mirror, and stretch the image
to make it seamless. These operations produce a texture which is repetitive and
blurry, and displays telltale "ghosting" artifacts that make the textures they
output virtually worthless.
STG avoids these issues almost entirely, and goes a step further, providing you
with the ability to correct for flash and even out brightness across the
image... features you'll be hard pressed to find in other products.
