Different types of file formats allow you to decrease or increase the size of your media files. The picture quality of each file will be effected. For further information about different file types then please read the next section below.

File Types

Digital cameras work within the following range of file formats:

JPEG - This is the most common picture file format used by camera manufacturers as it creates the smallest file size and is universally accepted by digital imaging software. It is recommended that you use the highest file quality setting (i.e. no compression) to maintain the best image quality.

TIFF - The image quality from these files is better than JPEG. They take up more file space than JPEG or RAW and can take longer to write to memory.

RAW - This file type is the nearest to a true film negative as the camera itself does not process the picture. Since there is no accepted standard for RAW files, each manufacturers format is different.

As you can see from the above, there are differences between each of these file formats. Generally, serious amateurs and professionals will only work with RAW files.
