Exposure and shutter speed

• Exposure: what really is exposure ?

In simple words, exposure is the professional term for light.

The three types of exposure are : - Underexposed 

                                                     - Optimal exposure 

                                                     - Overexposed 

In an underexposed picture you get very good details of the sky. Optimal exposure is normally the default setting of a camera and lastly overexposed is where you capture the mid-tones of a photo.

Usually we control the exposure to show the emotions in the subjects face but in glamourous shoots we use high-key lighting to show everything well glammed.

High Dynamic Range (HDR): It's the type of photography where you mix together the three type of exposure in one photo.

Three pillars of exposure

• Shutter speed :

Shutter speed is exactly what it sounds like: It's the speed at which the shutter of the camera closes. A fast shutter speed creates a shorter exposure — the amount of light the camera takes in — and a slow shutter speed gives the photographer a longer exposure.

• ISO :

A lower ISO value means less sensitivity to light, while a higher ISO means more sensitivity. It's one element of photography's exposure triangle — along with aperture and shutter speed — and plays an essential role in the quality of your photos.
