Steps to achieving rack focus:
1. Zoom in.
2. Set camera onto manual focus mode and select the lowest possible f-stop.
3. Place the camera so that the first object is in focus.
4. Press the record button and slowly start shifting the focus so that the second object comes into focus gradually.
The rack focus is used in film to shift emotional focus from one person/ one part of the shot to another person/ different part of the shot.
IN AND OUT OF FOCUS
Focus on subject of your choice and blur the subject after a desired time. Zoom out and focus again.
This effect can be used to change the viewer's perception of subject in the moment the shot is out of focus.
BOKEH
1. Use the right lens.
All lenses can create some kind of bokeh, but lenses with large apertures, like f/1.4 and f/1.8 give nice effects.
2. Select a large aperture.
3. Get close to your subject.
4. Focus on what you want to have sharp.
5. Put your subject far from the background you want blurred out.
Bokeh can create an aesthetic background for the main image. The bokeh effect also brings attention to the main subject.
DEPTH OF FIELD
1. Shallow Depth Of Field – Shallow depth of field means that a small portion of the picture is in focus. This is accomplished by using wide apertures.
2. Great Depth Of Field – great depth of field means that a big portion of the picture is in focus. Great Depth of field is achieved by using the short focal length of the point and shoot camera.
