Deep Depth of field better then shallow Depth of field?

Question:In my school photo-shoot I, we had to take putures for a project and I shot all my pictures with a deep Depth of field, now my teacher is saying I have to explain why I used deep Depth of field instead of a shallow Depth of field. Can someone please help me with the advantages of deep Depth of field. Thank you in advance

A deep depth of field will keep everything in focus, including objects or people close to you, and everything in the background. It is quite good for landscape or architectural shots, technical photographs, or close ups.

A shallow depth of field will only focus on the on the object or person you have photographed. Everything else will be out of focus. This is useful for portraits for instance, because it draws the veiwer's eye to the person photographed, and softens any distractions in the background.

A deep depth of field allows most, if not all of the photo area to be in focus, front to rear.
A shallow depth of field allows the main subject to be "isolated" within the frame. That is, only the main subject is in sharp focus. This is very useful, for example, in portraiture, where the background might detract or distract from the main subject.
At least, I think that's right!

Deep, for landscapes where you require everything in focus.
Shallow, for portraits where the background would detract from the subject

A narrow depth of field allows you focus on just one small part of the photos, thus it it used to EMPHASISE the subject concerned.

You have to listen in lectures friend!

You chose your depth of field for different reasons:
1. Accentuate or draw the viewer to a particular section of the image.
2. For the aesthetics of the image.
3. Because you want to do something quirky and different.

Generally landscapes are shot in the deepest depth of field but then again many contemporary artists choose something in the landscape to pull into sharp focus by so doing they use a shallow or narrow depth of field.

Generally portraits are done in shallow depth of field and the camera is focused on the eyes. If the depth of Field is very shallow you'll find the end of the nose out of focus. I always choose a medium depth of field for portraits so that the full face and hair are in focus but the background is out of focus.

Whenever you take a photograph you need to make conscious decisions before you start. Your lecturer is right to ask why you have done certain things. You must always think through your image before you start.

Draw a triangle on its side.
Look through the base. = shallow depth of field = main subject.
Look through the point to the base =deep depth of field = landscape all in focus.
