The ISO Value in Photography<\/h1><\/span><\/div><\/div><\/div><\/div><\/div><\/div><\/div>The ISO value of your camera is one of the three most important camera settings in photography. It can significantly affect the look and feel of your photos. What exactly is the ISO value, and how does it affect your photos? It\u2019s a good thing that you are a photography beginner. A fundamental first step. In this article, I will explain what ISO is and how you can use it effectively to get better images with your camera.<\/b><\/p>\n<\/div>What is the ISO value?<\/h2>\n<\/div><\/div><\/div><\/div><\/div>ISO values of your camera<\/h3>\n<\/div>The ISO value is specified at different levels. For most cameras, the lowest ISO value is 100, but there are some that start at 50. Each camera has a varied ISO range (sometimes called ISO sensitivity) that you can use. The value you set then doubles, resulting in a series with the sequence:<\/p>\n
\n- ISO 100 (low), 200, 400, 800, 1600, 3200, 6400 (high)<\/strong><\/li>\n<\/ul>\n<\/div>
In simple terms, the ISO value affects the light sensitivity of your image sensor (the full explanation is a bit more complex). The higher the ISO value, the more sensitive the image sensor becomes. At higher values, less light needs to fall on the sensor, and you still get a correctly exposed image. The opposite is, of course, true for low ISO values. As a result, the ISO value can be beneficial when shooting in a dark environment. You can also be more flexible in adjusting various other settings, such as shutter speed and aperture.<\/p>\n
The meaning of these numbers is straightforward: if you double the ISO, the brightness of the image doubles. An image with the ISO 400 is, therefore, under otherwise identical conditions, twice as bright as an image with the ISO 200. But at some point, this is over. In the picture opposite, you can see how much the image changes when you increase the ISO from 200 to 1600.<\/p>\n<\/div><\/div><\/div>

<\/span><\/div><\/div><\/div><\/div><\/div>Are high ISO values better?<\/h3>\n<\/div>The reverse is the case. An increase in ISO always has consequences. A photo with a high ISO value contains a strong grain, which is called “image noise”. An image with excessive noise may not be usable. Lightening an image by increasing the ISO setting is, therefore, always a compromise. If possible, you should always try to slow down the shutter speed or open the aperture further first to adjust the brightness and get better results. Unfortunately, this is not possible in some situations. For example, when an object becomes blurred due to longer exposure times. More about this later.<\/p>\n<\/div>

However, the ISO of the camera does not directly refer to this organization, which creates various standards in technology and research.
