The images of the two darker spiders were taken about an hour apart and they would appear to illustrate different individuals. They were on a part of the board that is more shaded, the third (lighter) spider being on a more sunlit area.

Brightness and colour temperature controls were adjusted after uploading to make the backgrounds in these images broadly equivalent i.e. the spiders appear to be genuinely dark or light.
