Above. Two views taken with a 35-105mm lens. The third image was taken with a 300mm lens. The true relative size of Mars compared to the Moon is best shown in the last image. Here the exposure is a short 1/4 second at f4.5 reducing halation/lens flare and does not show the illumination of the high cloud in the atmosphere. Using Fuji Velvia 50 ASA has produced a different and more saturated colouration in these images due to reciprocity failure, that is, exposing film longer than it is designed to be.

This image was also shot using Fuji Velvia 50 ASA and using a 6x6cm Rollieflex with a very wide f.4, 40mm lens (equivalent to about a 21mm lens on a 35mm format camera).
The richer colors in this photo are a result of slight under exposure and using slow speed film. To the eye only a slight bluish aureole was seen around the moon at the time. The orange coronal ring surrounding the blue core ring was too faint to be observed visually. The more saturated colors in this image are as they appear on the original transparency. To the eye it more closely resembled the image at the top of this page however even in that image the reddish coronal ring was so faint as to not actually be noticable at the time. |
