Histogram

A graphical representation of the brightness of an image. The horizontal axis represents the brightness and the vertical axis represents the number of pixels. High points at the left (too dark) and right (too bright) on the histogram indicate a photo that is improperly exposed.

ISO sensitivity

The sensitivity of the camera to light, based on the equivalent film speed used in a film camera. At higher ISO settings, the camera can use a higher shutter speed to reduce blur caused by camera shake and low light.

However, images with a high ISO setting are more susceptible to noise.

HEVC

High-efficiency Video Coding format, established by the international standard organizations ISO-IEC and ITU-T. This codec is capable of providing good video quality at low bit rates.

JPEG (Joint Photographic Experts Group)

A lossy method of compression for digital images. JPEG images are compressed to reduce their overall file size with minimal deterioration of the image resolution.

Image sensor

The physical part of a digital camera that contains a photosite for each pixel in the image. Each photosite records the brightness of the light that strikes it during an exposure. Common sensor types are CCD (Charge- coupled Device) and CMOS (Complementary Metal Oxide Semiconductor).

IP (Internet protocol) address

An IP address is a unique number that is assigned to every device that is connected to the internet.

Metering

The metering refers to the way in which the camera measures the quantity of light to set the exposure.

MF (Manual Focus)

A system that manually focuses the camera lens on the subject. You can use the focus ring to focus on a subject.

The Samsung EV-NX500 series, consisting of the EV-NX500ZBMICH, EV-NX500ZBMIHU, and EV-NX500ZBMHHU, is a remarkable leap in the realm of compact digital cameras. These models are designed to cater to both amateur photographers and seasoned professionals seeking high-quality images without the bulk of traditional DSLRs.

At the heart of the NX500 series is the 28 MP APS-C sensor, which delivers stunning detail and vibrant color reproduction. This large sensor size allows for improved performance in low-light conditions, enabling users to capture clear photos even in challenging environments. The back-illuminated design of the sensor enhances light sensitivity, resulting in better image quality and reduced noise at higher ISO settings.

One of the standout features of these cameras is their 4K video recording capability. The NX500 series supports UHD 4K video at 24 frames per second, allowing videographers to capture cinematic-quality footage. The inclusion of advanced video technologies like H.265 codec ensures efficient storage and playback without sacrificing quality, making it ideal for content creators focusing on high-resolution video projects.

Another defining characteristic of the Samsung NX500 models is their compact design. Weighing in at just around 280 grams, these cameras are lightweight and portable, making them perfect for travel and everyday photography. Despite their small footprint, they boast a robust build quality, ensuring durability during use.

The EV-NX500 series also features advanced connectivity options, including built-in Wi-Fi and NFC. This makes it easy to transfer images to smartphones and tablets for quick sharing on social media. The cameras are compatible with the Samsung SMART CAMERA app, which provides additional control and editing options directly from mobile devices.

An intuitive user interface enhances the shooting experience, with a tilting touchscreen display offering flexibility for framing shots from various angles. The customizable controls allow users to adjust settings quickly, providing a seamless transition between photography and videography.

In summary, the Samsung EV-NX500ZBMICH, EV-NX500ZBMIHU, and EV-NX500ZBMHHU represent a fusion of technology and portability, boasting high-resolution imaging, 4K video capabilities, and advanced connectivity features. Whether for casual use or professional endeavors, these cameras stand out as versatile tools for capturing the world in stunning detail.
