The grayscale level is so limited and the dot size appears so large it was difficult to determine what I was actually seeing. With complex scenes of flowers or people, it wasn't easy to discern the subject. To make matters worse, I often encountered reflections competing with the preview image. An anti-glare screen would be useful. Medium to bright light affords better photographs.
Lighting is also problematic.
Even with a steady hand, you'll probably encounter artifacts around light sources and sometimes throughout the entire image. Pictures shot in medium to bright indoor light or in bright sunlight, however, offer decent results. Downloading the images to the computer was fairly straightforward using the cradle supplied with the Palm IIIx. The process can take several minutes, depending on the organizer, settings, and the number of images. After downloading and opening the images, I discovered that the image settings had changed between 640x480 and 320x240 despite having set the mode to 640x480 on the Palm IIIx itself.
