Course 1 Relationship among ISO, shutter speed and aperture. – ISO – Shutter Speed – Aperture – Conclusion Navigator

Relationship - ISO +ShutterAperture Course 1

What is ISO ISO speed control the sensitivity of the sensor (film) that absorb light Details   Camera structure Camera function Course 1Relationship

Disadvantage of ISO +/- Low quality image, lost of picture details. (Image noises) Dark Images Not clear Image (Slow shutter speed) Course 1Relationship

advantage of ISO +/- Bright image Clear Image (fast shutter speed) High quality  less noise Course 1Relationship

Course 1Relationship

Not clear Image  slow shutter speed Course 1Relationship

Low quality of Image  Noise Course 1Relationship

What is Image noise  color spots (very small) on the image. Why?  Created by the static electronic or fast electronic current through sensor. Course 1Relationship

Why there? Thus, the higher the ISO is, the more noise the image has. Course 1Relationship Stronger, higher voltage or faster e+ current pass through the sensor. Weaker, lower voltage or slower e+ current pass through the sensor.

Shutter speed  It determines how long shutter remains open status as the picture is taken slower speed  longer exposure (brighter) faster speed  shorter exposure (darker) Course 1Relationship

Example of slow/fast shutter Course 1Relationship Fast shutter speedslow shutter speed

Aperture The hole in the lenses  review review It define the size of the opening in the lenses that can adjusted to control the amount of light reaching the film or sensor. Course 1Relationship

Larger  larger amount of light – Decrease the ISO speed and shorter shutter speed  shorter Depth of field Smaller  Opposite, less amount of light – Increase the ISO speed and longer the shutter speed  deeper Depth of field Course 1Relationship

Depth of field Depth of field is a concept of measurement that represent the range of distance within an image where the focus is acceptably sharp. Course 1Relationship

Course 1Relationship Shallow depth of field Deep depth of field

In photography, the shutter speed and aperture together control the total amount of light that reach to sensor.

Course 1Relationship

BEGIN

When saying “the higher ISO speed”, that means the shorter shutter opening time. YesNo

Aperture is a hole that can adjusted it size on the lenses YesNo

Shutter speed and aperture together control the total amount of light that reaching the sensor. YesNo

Depth of field is only deal with the shutter speed. YesNo

Images noise is created because when you are taking photo, somebody talking loudly around you. YesNo

Course 2 (bonus) White balance Basic adjustment

White balance White balance is the process of removing unrealistic color casts, so the color appear white in person but rendered white in photos. White balance also due with color temperature Course 2 (bonus)

Common white balance setting on the camera

Basic adjustment Sharpness/contract Tone/hue Color/saturation Course 2 (bonus)

Contract & Sharpness of photo Contrast is defined as the separation between the darkest and brightest areas of the image. Increase contrast and you increase the separation between dark and bright, making shadows darker and highlights brighter. Decrease contrast and you bring the shadows up and the highlights down to make them closer to one another. Adding contrast usually adds "pop" and makes an image look more vibrant while decreasing contrast can make an image look duller. Here is an example where we add some contrast. Course 2 (bonus)Basic adjustment

Contract & Sharpness of photo Sharpness can be defined as edge contrast, that is, the contrast along edges in a photo. When we increase sharpness, we increase the contrast only along/near edges in the photo while leaving smooth areas of the image alone. Let's take a look at an example with increased sharpness. rpness.htm rpness.htm Course 2 (bonus) Basic adjustment

Tone, hue, saturation Saturation is similar to contrast, however instead of increasing the separation between shadows and highlights, we increase the separation between colors. An example showing increased saturation would show the same effect as figure 3 above for the red image but the B/W image would not change at all because B/W or gray detail has no saturation. As a result, an increase in saturation results in an increase in contrast, brightness, and sharpness on the red image as in figure 3 and no change to the B/W image. Again, a change in saturation normally has a more noticeable effect on vibrant colors and less on dull colors or colors that are almost neutral. This is because to change saturation, there must be some color saturation to work with in the first place. Course 2 (bonus) Basic adjustment
