Morning and Evening Sun

If you are going to be taking doll photos in the sun, the best time of day to do it is either first thing in the morning or late in the evening.  Then the sun is low in the sky so you won't get unattractive harsh shadows as you do if the sun is high overhead. The light is especially nice if there's haze on the horizon to soften the light even more. Here's Nami & Byuri first thing in the morning....

They are in full sun, but the light is a lot softer so shadows aren't nearly as harsh. 
Here's Bonnie in late day hazy sunshine....

Again, the shadows are nice and soft.   
 Here's another photo of Elin taken in very late day hazy sunshine....

..and a late day scene just as the sun is about to set into some clouds on the horizon....

The light gets stronger the higher the sun gets, and shadows get stronger as well. Once the sun is higher and shadows stronger, it works best to have the doll facing directly into the sun in order to minimize shadows.  Here's Elin later in the morning.

Here's another shot taken a bit later in the morning with really bright sunshine in a completely 
white environment, while the sun was still low enough to shine right into the doll's faces.....
