To focus, the shutter button must be pressed halfway down to focus on the subject. On the 3-inch LCD screen, you will see a square (green) surrounding the subject after clicking once. When you press again, the shot will be taken. Accurate focus is essential for any photographer, and the Pixpro AZ252 offers a variety of features that can help you achieve sharp images even in difficult lighting conditions. Here are a few tips to help you get the best results from your camera: Use manual settings - When shooting in difficult lighting conditions, using manual settings can often result in sharper images. This allows you to control everything from the aperture to the shutter speed, resulting in sharper images with less noise. Use a tripod - A sturdy tripod can often provide the necessary stability to achieve accurate focus. In addition, using a tripod can also reduce camera shake, which can often result in blurry images. Shoot in RAW mode - RAW mode captures more information than JPEG mode, which can often result in sharper images. If you're shooting in difficult lighting conditions, switch to RAW mode and let the camera do its job! Shoot multiple exposures - Sometimes it's impossible to get sharp images without using a tripod or using manual settings. In such cases, shoot multiple exposures and then choose the best one for your needs. This technique is often called "stacking" and is a great way to achieve accurate focus in difficult lighting conditions.
