File Type

The TIFF format version of the postcard did not upload. TIFF files can be chosen to be either a lossless or lossy type. Generally lossless TIFF file have no compression meaning they are extremely high quality but have a large file size. They also can contain layers.

The PSD type file also did not upload. PSD files are the default type used in most graphic  programs. It allows layers and full editing of that image. Files are usually large. Unfortunatily if the sofware changers you may be unable to open it.

File Type

This image is a JPEG. JPEGs are good for compressing files while still keeping high quality images. They have a full range of colours and only discard very hard to see infomation. The amount of compression is adjustable. On the  postcard you can notice a small amount of blurring in some of the smaller writing but nothing every obvious. This is a good chose for keeping a high quality without taking up to much space, so long as you don't mind lossing a small amount of detail.

File Types

This is saved as a GIF file. GIF files are a lossless save type, meaning that it doesn't get rid of any imformation, only change it for a more effective compression. GIF files have a maxium of 256 different colours that can be used, if there is a different color used the software will find a color in it's palette that is the closest match and replace the orginal colour with it. This isn't a good type for my postcard because it makes some of the colours quite blocky.
