Vari-angle LCD Screen

One of the most notable features of the Nikon D5100 is its vari-angle LCD screen. This 3-inch screen can be tilted and rotated, allowing you to shoot from various angles without having to contort your body. It also has a resolution of 921,000 dots, providing a clear and sharp display of your photos and videos.

The vari-angle LCD screen is also useful for shooting in live view mode, where you can see the exact framing of your shot before taking the picture. This feature comes in handy when shooting in awkward positions or for vlogging purposes.

The Nikon D5100 has a range of special effects and filters that you can apply to your photos and videos. These include selective color, miniature effect, night vision, and silhouette, among others. These effects can add a creative touch to your images and videos without the need for post-processing.

You can also preview these effects in real-time on the LCD screen before taking the shot, giving you a better idea of how your final image will look. The camera also has a retouch menu, which allows you to edit and enhance your photos directly on the camera.

In-Camera HDR

High Dynamic Range (HDR) photography is a technique used to capture a wider range of light and dark tones in a single image. The Nikon D5100 has an in-camera HDR feature that combines two shots taken at different exposures to create a single image with more detail in both the highlights and shadows.
