Alpha Channel masking

Alpha channel masking is also a technique of separating images like the layer masking but it is superior to that of regarding the file size, it is lighter which makes the process of downloading or uploading flexible. Actually, after extracting the image from the background by clipping path, image masking etc. it is saved as an Alpha channel which gives the designers a scope to edit the brightness and contrast, exposure, color correction, hue/saturation etc. It is also used for selecting or separating the product from the background. Alpha channel masking is pixel based masking which displays images, actually the shape of images rather than a color. It has 256 levels of gray color because it is an 8-bit channel. Every image has 3 colors or more like red, green and blue. In alpha channel white color determines the visibility, the black is for invisibility and the quantity of gray color says how much the image will be visible, that means 50% gray defines 50% visibility. The alpha image is called RGBA, here A for alpha channel. All types of products can take the service of alpha channel masking especially the product images which have hair, fur or muslin like portions such as doll, cat, dog, human images, wedding photos etc.
