Most of us love the 3D pop effect of a shallow depth of field photo. It’s practically impossible to get these effects with a phone camera, so it’s crucial to use a DSLR or a higher end compact camera to achieve these effects. Even with a prime lens at the widest for the best bokeh, it means you may not get the entire subject from front to back in focus either. Focus stacking technique lets you keep the beautiful bokeh background while having full control of what objects to keep in focus.
