The image sets
They consist of a set of telephoto and a set of wide angle images. Below the telephoto image is a cropped detail image of a nearby roof gable end and below the wide angle image a cropped detail image of a distant birch tree. A cropped image of the corner of the wide angle image is also shown below this, this corner image is useful to observe edge sharpness and chromatic aberrations against the bright sky.
Zooming the images
The images can be enlarged by clicking on them, the larger image that pops up can be clicked again and a scrollable 24MP image is shown. Clicking on this image toggles between the full size and medium size image. Images can be closed by either clicking on the cross to the top right of the image or outside the image area.
