Simple TIPs about using ISO in photography.

ISO denotes the sensitivity of image sensor in the different amount of light present. I have taken photos here with following ISO speed. These photos are in the following order 

• ISO Auto mode,
• ISO HI,
• ISO 80,
• ISO 100,
• ISO 200,
• ISO 400 and
• ISO 800.

These unedited photos are taken indoor using flash, without tripod.

ISO speed affects the shutter speed.

If there is less light then use the higher ISO or Auto mode.

But Higher the ISO speed higher the noise.

Hint:

For High Quality photos – use low ISO

If enough light – use low ISO
