D2: Discuss the impact that file format, compression techniques image resolution and colour depth have on file size and image quality.
In this report, I will talk about my understanding of the impact in various file format, the different compression techniques, and different resolutions and different colour depth. I will show print screens of different types of compression techniques, megapixels under image quality & resolution and three different types of colour depths. I will explain the reasons why some are larger compared to others. The format includes PSD, JPEG, TIFF, BMP and GIF. I will also go into detail why colour depths will affect the quality of the final output that the file has created.

File formats:
As you know, there are 5 different types of file formats that you could find when saving an image or when looking up an image under at the end of the title named under PSD, JPEG, TIFF, BMP, and GIF.

The format PSD is used within Adobe Photoshop and this format is a default format for this software that allows saving the edited graphical images automatically to this specific format and also edit and/or change specific layers. Therefore the file allows you to open the file straight in Photoshop and edit the image plus use most of the features of the software.
