► Due to recently emerged information about a security breach in NordVPN, and the way the situation was handled and communicated, I can no longer recommend the use of this product.

To the people that have possibly been affected by the issue, after purchasing the product using the sponsored link on this video, I can only express my sincere apologies.

In computer graphics, there are two types of transparency.
The first is full transparency which basically describes something that is completely invisible, and it’s usually applied only to parts of an image. Of course, it can be applied to the entire image, but then there would be nothing to see.
And the second is partial transparency, which describes graphics that are, surprise-surprise, only partially transparent. So they’re visible to an extent, but so are the ones in the background. This kind of transparency is also commonly referred to as translucency, and computers usually simulate it by mixing colors.
In most computer graphics editors, transparency is represented with a distinct pattern, most commonly a checkerboard, and it’s supported in a number of raster or bitmap file formats, including: PNG, GIF, JPEG 2000, BMP and TIFF.
In optics, transparency is the physical property of a material that allows the transmission of light. Here's how that is simulated in computer graphics!
