Unsharp mask, desaturation and vignetting


For this picture I used auto colour. I achieved this very simply by uploading the picture I wanted onto photoshop and selecting auto colour. It instantly (although very subtly) changed the look of the picture.


For this picture I desaturated it and changed the brightness and contrast so that the black was darker and the white was whiter. To do this, I first had to select desaturate. I then chose brightness and contrast and altered it until it looked the way I wanted it to.


In this picture, I used a special range uf tools named vingetting and unsharp mask. I started this process by selecting filter, sharpen, and then unsharp mask. When this was done, I then had to start vingetting the image. I started this by selecting the eillptical marquee tool, and drawing an oval shape around the centre of the image, I then had to 'feather' the image to around 120 px, and then I inverted what I had selected so that it no longer highlighted the middle, but highlighted the outside of the oval around the picture. I then clicked on brightness and contrast, made it a little darker and then selected 'cntrl + D' which deselected it and the photo was done. After this I played around a little with the dodge and burn tools, which select a small area of the image and either, lighten or darken them. I lightened (dodge) the eyes a little to make them brighter.

Overall, I think my images came out quite well after altering them on photoshop. My favourite would definitely be the vingetting and unsharp mask as it was the most challenging, yet the most fun as I could change all sorts of different things on the image. The first was the easiest as i didn’t really do anything but click a button, and for the second it was a little more demanding since there was more to do, however still very simple.
