To avoid this problem, navigate to the High ISO NR command and switch it from the default of [Normal] to either [Low] or [Off]. We use [Off], and if the noise is too annoying, we reduce it with third-party noise reduction software, like Noise Ninja. The command path for controlling in-camera noise reduction is as follows: MENU > Camera Settings

Also, it is easy to miscalculate when you use the GN. Three errors may arise. The first is ISO. If the ISO is not stated, it is assumed to be 100. If you use a higher ISO than this, the GN needs to be increased to compensate for the sensor’s increased sensitivity to light. If you set your camera to ISO 200, you should double the GN. The second sour

There are 12 buttons that can be customized to execute menu commands. The way you customize them is controlled by two commands in the Setup menu: Function Menu Set. and Custom Key Settings. Together, they can control 23 menu commands.

If we do not need this level of performance, we use the noise reduction feature in Adobe Photoshop CS. Although it is not as good as what we can obtain with DxO, it operates faster, works on RAW files, and is superior to the a7 II High ISO NR setting.

Usually, some features must be sacrificed, such as autofocus, image stabilization, or both. However, you can avoid this disadvantage if you buy Sony A-mount lenses and the appropriate lens adapter. If you use this approach, you can purchase a 500mm lens, which has automatic focus and image stabilization. We’ll discuss these options in chapter 9.

The longest shutter speed for P, A, and S modes is 30 seconds. M mode extends the available shutter speeds and allows you set an exposure of at least 5 minutes.

Fortunately, you can still get the picture by raising the ISO. This comes at a cost because it reduces the range of light (the dynamic range) that the sensor can record. You may end up losing detail in either the shadows or the highlights. The image becomes granular—that is, areas that should be rendered as smooth tones become speckled with blotche

you can use a handy feature with the C2 button. It normally activates the Focus Settings command.

As we mentioned previously, a higher ISO results in increased noise, so we tend to photograph at ISO 1600 or lower. If you are forced to work at a higher ISO, you might want to try the High ISO NR command. It only works on JPEG files at ISO 1600 and higher. No second exposure is required to capture a dark frame; it works on just one image. You can
