as asked in part one we had to find a vertical and horizontal lined subject and make it as square as possible. we tested at both extremes of the lens, took a photograph or the scene on 55mm zoom..
and then the same scene on 200mm zoom..
..after that we moved the zoom lens to many different zoom lengths and then looked at our images, decided on which image created the sharpest, strongest view, without distortion which happened to be at 70mm on the lens.
part two asks us to take a range of photographs at different zoom settings and try to establish at what point in the zoom the chromatic aberration appears. We found a small amount yet we were unable to fix the image using Photoshop as to much green or to much red in the image.
