This lesson we learnt that the ideal shutter is not technically possible.

In a focal shutter plane the flash should only operate when the shutter is fully open hence the flash synch is limited.

We also learnt about depth of field.
Boundaries of depth of field are referred to as D1 (For the near limit) and D2 (for the far limit)
Subject distance (u) refers to the distance from the camera to the subject...

We need to remember that the larger the aperture = the shallower the depth of field.

To INCREASE your D.O.F you need to *Use a smaller aperture
* Use larger subject distances
or * Use a wider angle lense

F4 = Shallow F32 = Deep.
