The Green Energy bundle contains 3 variations of an image (3000×2250 at 300 ppi) of a Newton’s cradle in different settings and an image of isolated grassy spheres. The images are in 8-bit RGB mode, in transparent PNG format and are all rasterized. The same images are also placed in a .psd file with a correlated Alpha channel. Also included is a sequence of 50 images (800×600 at 300 ppi) that make a simple animation of the cradle in motion. These images are also rasterized, in 8-bit RGB mode and in transparent PNG format. You can use the images in printed publications, to enhance your web design or even in something like green-themed wedding invitations (http://www.sanchi.si/green_energy.html). The ideas are limitless.
