Shutter speed

Shutter speed refers to the amount of time it takes to open and close the shutter, and it is an important factor in the brightness of a photo, as it controls the amount of light which passes through the aperture before it reaches the image sensor.

Usually, the shutter speed is manually adjustable. The measurement of the shutter speed is known as the “Exposure Value” (EV), which is marked in intervals of 1 s, 1/2 s, 1/4 s, 1/8 s, 1/15 s, 1/1000 s, 1/2000 s, and so on.

The numbers indicated on the camera are the denominators of exposure values, which means that the higher the number, the less light will be let in. Likewise, the smaller the EV number, the more light will be let in.

As the photos below illustrate, a slow shutter speed allows more time to let light in, so the photo becomes brighter. On the other hand, a fast shutter speed allows less time to let light in and the photo becomes darker and more easily freezes subjects in motion.

NX100 specifications

The Samsung NX100, launched in 2010, marked a significant entry into the mirrorless camera market, showcasing the brand’s commitment to innovation and style in photography. This compact system camera combined versatility with advanced technology, appealing to both amateur and professional photographers alike.

One of the main features of the NX100 is its 14.6-megapixel APS-C CMOS sensor, which delivers stunning image quality and excellent low-light performance. This sensor size is comparable to that found in many DSLRs, allowing for greater depth of field and better control over exposure. The impressive image resolution enables photographers to capture intricate details without sacrificing clarity, making it ideal for large prints.

In terms of design, the NX100 boasts a sleek and stylish body that is both lightweight and compact, making it easily portable for photography on the go. The camera features a detachable lens system, compatible with Samsung's NX mount lenses, allowing users to tailor their equipment to the specific needs of their shoots. The standard 20-50mm lens provides great versatility for everyday photography.

The NX100 incorporates a Hybrid AF system, combining contrast detection and phase detection to achieve fast and accurate focus, an essential feature for capturing moving subjects. Furthermore, the camera supports continuous shooting at 3 frames per second, enabling users to capture action sequences with ease.

Another notable characteristic of the NX100 is its 3-inch AMOLED display, which offers vibrant colors and excellent viewing angles. This display is crucial for composing shots and reviewing images in varying lighting conditions. Additionally, the camera includes manual control options, giving experienced photographers the flexibility to adjust settings such as shutter speed and aperture, while also providing automatic modes for those looking for ease of use.

The camera's integrated Smart Filter effects allow for creative expression directly in-camera, offering options like Soft Focus, Vignette, and Miniature effects. These filters enhance the creative potential and make experimentation more accessible for users.

Enhanced connectivity is also a key feature, as the NX100 includes Samsung's i-Function technology, allowing users to adjust settings directly from the lens using designated buttons for a seamless shooting experience. The ability to connect via USB and HDMI provides additional convenience for sharing images and videos directly to external devices.

In summary, the Samsung NX100 reflects a blend of sophisticated imaging technology and user-friendly design. Its APS-C sensor, compact build, and innovative features create an appealing option for anyone looking to dive into the world of photography or expand their creative toolkit.
