We moved an evening Advanced Studio Lighting class to Sunday afternoon so we could be outside. The intent was to work on Key shifting in an outdoor shoot. Key shifting down making the background darker than subject in the foreground and key shifting up making the background lighter than the subject in the foreground. All the while keeping in mind exposure latitude from 18% middle grey. 3 and 1/2 stops up to photographic white and 3 stops down to photographic black.
The sky was overcast and varied from light rain to sun peaking through during the shoot. Here are examples of key shifting up:
