Opposition Effect on Trees

The opposition effect is generally easier to spot when the apparent size of the individual shadowing objects is too small for them to be seen individually. However it can still be seen even among large trees under the right conditions.

Notice how the detail round the base of the balloon shadow seems less distinct than further away where the shadows are more obvious. The lack of visible shadows here means the apparent brightness is slightly greater.

You don't have to look very far from the antisolar point before shadows become visible. This is why the brighter area round the shadow is always quite small.
