another difference between J. Pagan roars compression, which is when the camera makes the far size smaller. If I was able physically to get hold of the picture, I've just taken which, with the magic of television I can do this is what it would look like. Now. Additional file isn't a single object is made up of lots and lots of pixels, so in reality is a little bit more like a jigsaw. Jake pegs air compressed. Using what is known is a lossy algorithm. What that means is the camera takes the picture. It identifies the pixels it wants to keep on. Then it looks at the pixels that because they're all the same, such as this area of blue sky here, it could afford to throw away literally. There are fewer pixels, and that's what makes the file size smaller. The problem with lossy compression is that one says discarded pixels are thrown away. They're gone for good. So why don't your photographs have gaps in them where those pixels are missing? Well, what happens is when you open the picture in t...
he computer, the software inter plates, that missing information. Basically, what it's doing is is guessing at what should be there now. It does a pretty good job most of the time, but it is guesswork, and sometimes it guesses wrong. So your pictures don't always look as good as they can be. Raw files, on the other hand, to compress using what is known as a lossless reversible algorithm. What that means is the camera takes the picture and it rolls it up into a smaller package a little bit more quickly, and I'm doing it right now. To be fair, it doesn't for away any pixels. So when you come to view the image, the software simply unrolls it, revealing all the original data.
