Picture Perfect is an image viewer. The image viewer is easy to use and the image viewer will not change any of your pictures settings. If you own a high dollar digital camera, you are aware of the picture setting you have control over as you take the picture. The last thing you would need is an image viewer taking your picture and changing the settings. You will no longer have the same picture you started out with. Of course if you have that type of camera, your pictures are art and you don't need computer software messing with your art.
