- Set the focus a bit further away from your initial subject and snap another picture
- Repeat step two until you have enough pictures
Is Focus Stacking the same as HDR?
No, although the principles are highly similar, the end-results are wildly different. Focus stacking means increasing the effective Depth-of-Field (DOF), while HDR involves increasing the effective Dynamic Range.
