WEEK 4 (APERTURE & SHUTTER SPEED)

This week, I'm going to captures which is has big aperture vs small aperture and slow shutter speed vs fast shutter speed.

Let look the pictures below :

                                                      F25    :    0.62sec   :    ISO 800  

                                                           (low shutter speed)

 

                                                      F5.6    :    1/30   :    ISO 800

                                                             (fast shutter speed)

                                                      F5.6    :    1/140   :    ISO 800

                                                             (fast shutter speed)

                                                       F5.6    :    1/125   :    ISO 800

                                                             (low shutter speed)

                                                      F5.6    :    1/100   :    ISO 800

                                                             (fast shutter speed)

                                                     F29    :    1/2   :    ISO 800

                                                          (low shutter speed)

                                                      F5.6    :    1/100   :    ISO 800

                                                            (big  aperture)

                                                       F36    :    1/60   :    ISO 800

                                                               (small  aperture)
                           *But actually this picture is considered as overexposed..hahaha

                                                          F16    :    1/60   :    ISO 800

                                                                 (big  aperture)

                                                      F36    :    1/60   :    ISO 800

                                                               (small  aperture)
                        *But actually this picture is considered as overexposed..hahaha

                                                           F6.3    :    1/100   :    ISO 800
                                                                         (big  aperture)

Background is blur because of less of depth of field. Big aperture which is small number of f stop will caused less of depth of field.

                                                                 F14    :    1/60   :    ISO 800

                                                                          (small  aperture)

Background is clear because of  depth of field is increase. Small aperture which is large number of f stop will caused   depth of field is increased.

Shutter Speed

First off, slow shutter speed. We use this for two reasons . First, because it’s quite dark and we need to let more light into the camera. Or second, because we want to introduce some blur into our photo.

What? Blurry photos? Yep! That’s right. Sometimes we can use blur for a creative effect.

So, we can see from this pictures? In conclusion we know that if using fast shutter speed to freeze an action or to stop an action. If we are using

The key thing to remember about using a slow shutter speed is that anything that moves in the scene will blur. Once you're aware of this you can use it creatively in your photography.

If slow shutter speeds allow you to get creative with blur, fast shutter speeds have the opposite effect ,they freeze movement or stop an action.A fast shutter speed could be considered anything over 1/500th of a second. But modern digital cameras go much faster than this. If you have a digital SLR you may well be able to select shutter speeds up to 1/8,000th of a second – incredibly fast!

Depth of Field
 

As well as letting more or less light into the camera the size of the aperture we choose governs the 'Depth of Field'. Depth of field means the amount of the picture, from foreground to background, that is in sharp focus. A smaller aperture will give us a greater depth of field and a larger aperture will give us a more restricted depth of field. This characteristic can be used to good effect in many ways.

Depth of field (DOF) is a term which refers to the areas of the photograph both in front and behind the main focus point which remain "sharp" (in focus). Depth of field is affected by the aperture, subject distance, focal length, and film or sensor format.

A larger aperture (smaller f-number, e.g. f/2) has a shallow depth of field. Anything behind or in front of the main focus point will appear blurred. A smaller aperture (larger f-number, e.g. f/11) has a greater depth of field. Objects within a certain range behind or in front of the main focus point will also appear sharp.
