AREDS Report #4
The images from this report are available in digital form for viewing in two formats. The JPEG images are sized for short download times but with lower resolution. The TIF images are stand alone image files with much higher resolution (each is approx 3.5 Mb). Download times for these images will take upwards of 30 minutes with a 28.8 kbps dial-up connection. They are best saved on your computer and viewed with a stand-alone image editor.
