Digital Image File Types

File Type: JPEG

File Size: 109 KB

Particular characteristic: Although having a really good color scale (in fact full RGB color range) the size of this image is pretty small compared with the other 2 images.

File Type: PNG

File Size: 222 KB

Particular characteristic: The transparency of this photo represent perfectly the 256 different levels of transparency that a single png image can have.

File Type: GIF

File Size: 5,72 MB

Particular characteristic: The file size of this image is really big due to the amount of different photos joint into one to form an animated gif.

In this image we can clearly see the color quality loss due to the conversion to gif file type. This is caused by the limitation to 256 different colors that gif uses to compress the file.

In this image, although we can think that the trasnparency of the image is still there, it is not. Due to the change from png to jpg we remove the alpha channel of the image used to get that cool looking transparency that can result very useful for many webpages or image editing.

In this png image, we can clearly see a major change from the previous image to this one. When we change the flie type to png, all possible movement in the gif image is lost, as png type images don't support movement.

In this zoomed section of the image changed previously, we see perfectly the reduction of color range. This makes the image look grainy and unreal with a highly limited color range.

In this zoomed part of the image changed previously, we can just notice how the colors are a bit stronger than on the png image. The cause of this may be because of the amount of colors on each RGB model used.

In this zoomed image that we changed previously we can see how the colors are kept grainy and unreal although being a png file that could have up to 16 million colors
