How many brackets work best?

At least 3 brackets for best results. The AI just needs a dark bracket that's dark enough to see out of windows. In especially bright, sunny markets, shoot 5 brackets at ±2 EV instead.

Standard recommendation

3 brackets at ±2 EV handles most interior and exterior shoots.

For bright markets

In sunny markets like Florida or California, 3 brackets sometimes aren't dark enough to capture clean window views. 5 brackets at ±2 EV gives the AI a wider exposure range to work with on bright days.
