Programs that can efficiently let you change the background image for your pictures are usually very expensive and hard to find. A cheap solution comes from Green Screen Wizard, an application that brings you a wide range of output configurations and offers you quality results.
My first thought about using this type of application was that it's a very big chance that the results might not turn out the way I expected. This program proved me wrong; as with the help provided by its numerous image editing configurations I was able to make my picture look very professional.
You can adjust various color filters, alter front picture size according to your needs, reduce highlights and many other image editing procedures. A good thing is that you can preview any change you make to your pictures, though the program often takes a while to show the new alterations.
Finally, you can save your result to various image formats and print it directly from the application. My belief is that it's worth acquiring this program as it's very simple to use, gives you access to a wide range of output configurations and the results are of high quality.
