Photoshop

 

This is the orignal image I chose to make the three adjustments on.

For the image above I used the auto tone, auto colour and auto contrast tool. These make simple adjustments however can make a big difference to the quality of the image.
Auto Colour, Contrast and Correct: To use these tools I simply go to image then click on whichever I choose to automatically adjust.

On this image I desaturated the image meaning I drained it of all colour, I then editied the brightness and contrast to make the lightin gof the image match that of the contrast.

Desaturating: To desaturate an image I go image - adjustments - desaturate. Or I can use the keyboard short cut which is: shift, control, U.

Brightness and Contrast: To edi tthe brightness and the contrast of an image I click image - adjustments - brightness and contrast, then I can use the scales to decide where I want the levels to be.

For this image I used the unsharpen mask to make the eyes as sharp as possible. I also used vingetting to darken the outside of the image. Doing this drags the attention to the centre of the photograph which is also the most important part of the image.

Unsharpen mask tool: To find this tool I click 'filter' along the top bar of photoshop, open the sharpen option which then gives me the option of 'unsharpen mask' I click this and set the radius to 2.0 pixels, 2.2 pixels if necessary.

Vingetting: To do this I choose the elliptical marquee and select the area of the face and around it. Next I go onto select and inverse which means that any editting I do will be on the outside of the circle I drew.Then click image - adjustments - brightness and contrast, then turn the brightness down but keeping it subtle. Pressing control and D then saves any editting. I can darken my image further by using the burn tool which allows me to darken other areas of the image. If I choose to lighten areas of the image I use the dodge tool.
