Layer masking is one of the most popular image conversion methods that is used for more compound images where clipping path alone is not enough. This layer masking system contains a black and white layer mask that ensures the visibility or invisibility of an image or a part of it. The black and white layer mask is used to hide some part of an image or to make it visible, transparent, semi-transparent, or translucent. The white part of the mask reveals the pixels whereas the black part of the mask hides the layered part. The best part of using layer masking is, it is not destructive. It means, there is no unredeemable change done to an image in it. Neither the visible part nor the hidden part is changed that much drastically that it can’t be recovered ever. There is no certain omission of the pixels rather it leaves just a mask on images which can be easily removed whenever required and recovered the original image immediately. It is mostly used for advertisement display for e-commerce websites or other business purposes by pulling out backgrounds of sophisticated images and used the product images separately. Therefore, in product photography, online markets, film industry, poster making companies, layer masking is one of the most necessary equipments without which they can’t run their advertising and branding chain.
Clipping path is an image cutting technique done with image editing software. It is a vector masking technique of photo editing that helps the user to cut out a part of 2D and 3D images and use it for various purposes. However, this image cutting never brings any change to the original piece rather the original image is intact and clipping path creates a mask around the intended part of the original image. It is done using a closed vector path or shape that can be drawn either clockwise or anti-clockwise as the paths are generally defined by the directions of the paths. Conventionally, the clockwise path is called “inclusive path”, anything inside the path will be present in the final image and anything that is excluded from the path will not be visible in the final result. On the contrary, the anti-clockwise path is called “exclusive path”, anything outside the path will be present and the inclusive part of the path will omitted from the final results. Generally, Adobe Photoshop, Illustrator, CorelDraw etc. are the mostly used software for omitting backgrounds, making images translucent or for applying photo masking by using clipping path. Nevertheless, for compound images it is used for color correction. It is universally popular in online marketing, digital photography and photo studios, newspapers, magazine, and publishing company etc. use this technology for their products.
