That’s because small pixels are more likely to display digital noise.

In other words, you could get better picture quality from your mobile camera if you take a shot at 800 ISO than if you take a photo at 100 ISO and then brighten it up by a whole lot later when you’re editing.Ī large contributing factor to how high you can set your ISO level before you start noticing digital noise is the size of the sensor and the pixels on it. A camera with a large sensor and large pixels is more likely to be capable of reaching high ISO levels before introducing noticeable digital noise. Brightening the image in post will not yield the same results. Thanks to this system, the ISP will, to some extent, reduce the amount of noise that comes as a result of increasing the ISO. Part of this process is noise reduction, where an algorithm is applied to the image to reduce the amount of digital noise. Remember, when a mobile camera takes a picture, it goes through a processing pipeline in the camera’s image signal processor or ISP. While both methods do brighten an image and make digital noise more apparent while doing so, the image quality tends to be better when the brightness of an image is increased in-camera by pumping up the ISO than cranking up the brightness in an editing app. More on that later.īecause ISO basically brightens up an image that the sensor has already captured, many people may believe that brightening up a photo on a computer or a mobile app is the same as increasing the ISO on a camera. Whatever the ISO values are on your mobile camera, what you need to remember is that when you double the ISO value, you double the brightness of the image. You need to be careful, though, because there is a trade-off for increasing the ISO.

In fact, the Huawei P30 Pro is said to go all the way up to an unbelievable 409 600 ISO. Here is a common set of ISO values found on many mobile camera apps:Įvery mobile camera app is different and may, therefore, have its own set of ISO values that are different from the typical ones above.Įven though a lot of smartphone cameras only go up to 6400 ISO, some can go even higher. Of course, it’s not always possible to shoot using base ISO. That’s because shooting at base ISO means little to no visible digital noise. It’s important to try to stick to the base ISO to ensure you capture the best quality pictures.
On most devices, this number is set to 100 although some go as low as 50 ISO. The base ISO is the lowest native ISO setting on your smartphone’s camera.
