Recently I was thinking of upscaling my digital images. Some of the images from my old digital camera are just of 800 x 600 pixels, and I want to take out larger approximately 16 x 20 inches prints. To do that I need to upscale my images.

I use Adobe Photoshop CS3 and at the moment I am confused whether to go for Genuine Fractals, Reshade or Qimage. I dont know which one will give me the BEST results. I have searched but got conflicting reviews.

Can someone help me as to which of these softwares, will give me the best resolution clear upscaled images which will be superb to print

Thanks
