Why Are My Photos Grainy at ISO 100?
ISO is a measure of how sensitive your camera is to light. The higher the ISO, the more sensitive it is. But why are your photos grainy at ISO 100? This article will explain why and how to fix it.

Explain how to fix grainy photos at ISO 100
ISO 100 is the lowest ISO setting on most cameras. It is the least sensitive to light and should produce the best quality images. However, sometimes photos taken at ISO 100 can be grainy. This is because of the camera’s sensor and the way it processes light.
The camera’s sensor is made up of millions of tiny pixels. When light hits these pixels, they convert it into an electrical signal. This signal is then processed by the camera’s processor and converted into an image. At low ISO settings, the camera’s processor has to work harder to process the light, which can lead to grainy images.
Another reason for grainy photos at ISO 100 is noise. Noise is caused by the camera’s sensor picking up random electrical signals. This can be caused by a variety of factors, such as heat, electrical interference, or even the camera’s processor. Noise can be reduced by using a higher ISO setting, as the camera’s processor will be able to process the light more efficiently.
Finally, grainy photos can be caused by a lack of light. If the scene is too dark, the camera’s sensor will struggle to capture enough light to produce a good quality image. In this case, you may need to use a higher ISO setting or use a flash to add more light to the scene.
Good to know:
ISO: A measure of how sensitive your camera is to light
Sensor: The part of the camera that converts light into an electrical signal
Processor: The part of the camera that processes the electrical signal and converts it into an image
Noise: Random electrical signals picked up by the camera’s sensor
Grainy photos at ISO 100 can be caused by a variety of factors, such as the camera’s sensor, noise, or a lack of light. To fix this issue, you may need to use a higher ISO setting, use a flash, or adjust the exposure settings on your camera.
