Experimenting with a 0.48x wide angle macro lens - the CD 128 in focus in the front is a vivid green, almost 7-up green. I tried but could not capture the amber streaks running vertically though this piece (some call this "tiger striping"). Nearly all of the CD 128's from Uruguay I have seen have some degree of fine amber streaking in the glass. White balance was set to compensate for 5000k bulbs and I set exposure to +2/3. These insulators were found in and around the vicinity of Paysandu.
