In simple terms, ISO refers to the sensitivity of your camera’s image sensor to light. The higher the ISO setting, the more sensitive your camera’s sensor is to light, and the brighter your images will be. Conversely, the lower the ISO setting, the less sensitive your camera’s sensor is to light, and the darker your images will be. ISO is expressed in numerical values, with lower numbers such as ISO 100 being less sensitive to light and higher numbers such as ISO 3200 being more sensitive to light.
When you increase your camera’s ISO, it amplifies the signal from the sensor, which results in brighter images. However, this amplification also introduces noise or grain to your images, which can affect image quality. Therefore, it’s essential to use the correct ISO setting for your shooting conditions to balance image brightness and image quality. In general, you should use the lowest possible ISO that will still allow you to capture a properly exposed image.
Using ISO to improve your photography requires an understanding of how different ISO settings affect your images. Here are some tips for using ISO to improve your photography:
1. Use low ISO for well-lit scenes
If you’re shooting in a well-lit scene, such as a sunny day outdoors, use a low ISO setting such as ISO 100 or 200. This will give you the best image quality and minimize noise in your images.
2. Increase ISO for low-light conditions
If you’re shooting in low-light conditions, such as indoors or at night, you’ll need to increase your ISO to maintain image brightness. However, you should also be aware that higher ISO settings can introduce more noise to your images. To balance image brightness and image quality, start by increasing your ISO to around ISO 800 or 1600, and then adjust as needed.
3. Consider using auto ISO
Most modern cameras come with an auto ISO feature that can automatically adjust your camera’s ISO based on the available light. This can be a convenient option if you’re shooting in changing lighting conditions and don’t have time to adjust your camera settings manually.
4. Experiment with high ISO settings
While high ISO settings can introduce noise to your images, they can also be used creatively to create unique images. Experiment with higher ISO settings to capture grainy or gritty images with a unique look. Read Also: Sony HDR CX405 vs. Sony HDR CX240
