Why I cannot offer an exact time of day for your session right away:

Outdoor photography using natural light is best done in the early morning, the late afternoon, or sometimes into the twilight. It depends on what "look" we are trying to achieve. Direct sun in the middle of the day, especially in the Summer, should be avoided. Therefore, if we are depending on natural light for our shoot we should begin an hour before the ideal light is expected to occur. If we are shooting with natural light "in-studio" the same limitation applies. Even if we opt for strobes, other artificial lighting, or light modifiers, I'll still need to confirm that the studio will be available on the desired day.

What do you plan to use the photographs for?

Explaing the purpose of the photographs will help me plan out your session and deliver the the type of images you want.
