There is a large difference in the quality of the images. When making the lower quality image larger than its original size the lines and edges in the image became jagged and rough, where as the higher quality image when made smaller than its original size kept its smooth edges and lines a lot more.

I have taken an image from National Geographic to demonstrate the editing of images; the photograph taken is ‘Tumbleweed In Mid Air’ by John Burcham.

I have edited this image, above, by increasing the brightness by +28 and the contrast of the image by +31.

For this edit of the image above I have layered two filters in order to change the image. The filters used were ‘cooling filter (80)’ and ‘deep red’.
