แบบทดสอบที่ 1 เรื่อง ความรู้เบื้องต้นเกี่ยวกับภาพ

The correct answer defines the meaning of a picture as something that is recorded and allows humans to see and convey meaning. It emphasizes that a picture enables humans to both perceive visual information and communicate its significance. The answer also suggests that the primary sense used by humans for perception is sight.

The given question asks for the color that is not part of the RGB color mode. The RGB color mode is a color model that uses combinations of red, green, and blue to create a wide range of colors. In this color mode, black is not considered a separate color because it is the absence of all colors. Therefore, the correct answer is "ดำ (BLACK)."

DNG (Digital Negative) is a file format used for storing raw image data from digital cameras. It is primarily used for archival purposes and is not specifically designed to support internet systems or web browsing. Therefore, it is not a graphic file format that supports internet systems.

There are two types of graphic images.

The given image that is formed by arranging small squares of different colors indicates a Bitmap image. Bitmap images are made up of pixels, which are small squares that contain information about color and brightness. Each pixel in a Bitmap image is assigned a specific color value, resulting in a mosaic-like appearance when viewed closely. This type of image is commonly used in digital photography and computer graphics.

WMF (Windows Metafile) is not a raster or bitmap image format. It is a vector image format that stores graphical images as a set of instructions for drawing lines, curves, and shapes. Raster or bitmap image formats, on the other hand, store images as a grid of pixels. Therefore, WMF is the correct answer as it does not belong to the raster or bitmap image formats listed.

A vector image is created by referencing mathematical relationships or calculations. This means that the image is defined by mathematical formulas rather than a grid of pixels. This allows vector images to be scaled up or down without losing quality, as the image is redrawn based on the mathematical equations. Vector images are commonly used in graphic design, logos, and illustrations.

When designing a large vinyl sign, it is recommended to use the CMYK color mode. CMYK stands for Cyan, Magenta, Yellow, and Key (black), which are the primary colors used in printing. This color mode is specifically designed for printing purposes and ensures accurate color reproduction. Using CMYK mode will result in better color matching and consistency when the design is printed on a large scale.

The correct answer is HSD. HSD is not a color model commonly used in graphic design. RGB (Red, Green, Blue) and CMYK (Cyan, Magenta, Yellow, Black) are the most commonly used color models in graphic design for digital and print media respectively. LAB is another commonly used color model that represents colors based on human perception.
