What is a bitmap in ps

What is a bitmap? Almost everyone who is new to graphic design will ask this question. In fact, if you don’t understand what a bitmap is, it will not have a big impact on your learning of design software. Of course, it is best to understand it.

Bitmap, also known as raster image, is generally used for photo-quality image processing. It is a graphic composed of many pixels like small squares. . Represented by the position and color value of pixels, it can show changes in color shades.

Simply put, a bitmap is a pattern composed of countless color points. When you zoom in infinitely, you will see pixel color blocks one by one, and the effect will be distorted.

Commonly used in image processing, film and television wedding renderings, etc., such as commonly used photos, scanning, digital photos, etc. Commonly used tool software: PHOTOSHOP, PAINTER, etc.

Photoshop mainly deals with bitmap images.

When you work with bitmap images, you can refine small details, make dramatic changes, and enhance effects.

Bitmap images, also known as bitmap images or drawn images, are composed of individual points called pixels (picture elements).

The dots can be arranged and colored differently to form a pattern. When you zoom in on a bitmap, you can see the countless individual squares that make up the entire image. The effect of increasing the size of a bitmap is to increase individual pixels, making lines and shapes appear jagged.

However, if you view it from a slightly further distance, the color and shape of the bitmap image appear to be continuous. Because each pixel is individually tinted, you can produce nearly photorealistic effects, such as deepening shadows and accentuating colors, by manipulating selected areas one pixel at a time. Reducing the bitmap size also distorts the original image because it makes the overall image smaller by reducing pixels.

Similarly, because bitmap images are created as arranged collections of pixels, partial bitmaps cannot be manipulated (such as moved) individually.
