Mastering DSLR Exposure & Creative Focus:  ISO, Shutter, Aperture & Metering

These auto modes are used to maintain good exposure while helping the photographer select distance (depth of field) and motion focus.)

Portrait (sharp figure and soft background average depth of field)

Landscape (sharp figure and sharp background with greater depth of field) Using this mode can also produce blurred motion in low light levels.

Macro (sharp figure and blurred background/mid ground for limited depth of field)

Sports (freezes the moving figure sharp with no consideration of depth of field)


Introducing Exposure’s Semi Auto Priority Settings

Programed: The photographer selects the starting point for the shutter speed to stop action and aperture setting for limited distance focus “depth of field” then lets the camera take over to control exposure.

(AV)  Aperture’s f/stops: The photographer chooses to set the f/stop settings (aperture variations) to control distance focus while letting the camera control exposure with the shutter speed.

(TV) Shutter Speeds: The photographer chooses to set the shutter speeds to control stop action (frozen motion to capture detail of the subject) panned action (sharp moving subject and streaked background in low light or to eliminate distracting background) or creative blurs (blurring the moving subject in contrast to a sharp background to exaggerate motion).

(M) Manual: The photographer chooses to set the shutter speeds to take full control of creative focus (motion and depth of field focus with both the shutter speeds and aperture f/stops) and exposure contrast to increase the power of subject, background and lighting relationship.

(WB) White Balance: Keeping whites white and colors true in all types of light.
