One of the selling points of the JamCam was that 800x600 pixel resolution was possible with the camera but, there is a catch. The true resolution for the JamCam is 640x480 pixels and 800x600 pixel resolution is only possible through a photo editor. 800x600 resolution is achieved by polarization, the use of a photo editing program SHARPEN PHOTO option.
Polarization takes place when the photo editor scans a photo, which is comprised of a series of round dots. These dots are superimposed upon a background which shows through where the dots do not abut each other - eg. the diameters of the dots would touch each other but the rounded corners would not. The rounded corners are where the background shows through.
The photo editor scans the dots for color, the adjacent dots for color and attempts to fill in the background spaces with its best guess of what color the background spaces should be. Digitally enhanced square colored pixels are inserted where the dots do not touch. This tends to smooth out and sharpen the photo image thereby increasing resolution.
The true resolution capability of the JamCam is not 800x600 pixels but rather 600x480. For a second generation digital camera this is an excellent resolution rating but further enhancement is possible. Go to the TRICKS AND TRICKS forum and see the posting 'THIS PHOTO ENHANCER DRASTICALLY IMPROVES MOST JAMCAM PHOTOS' about the DC Digital Photo Enhancer program. The use of this program will make a real difference in the quality of many JamCam photos by improving color and sharpness, reducing annoying color shifts and smoothing skin tones.
