Retouching Images
First Open your file in Photoshop.
Then using the Polygonal lasso tool which is located on the tool bar on the left this is to select the area that we want to work on, I have used this tool because by using it, it keeps any editing within the area you have selected.
To select the tool click and hold the lasso tool and you will get a drop down menu, then select the Polygonal lasso tool option.
With this tool you will select around the area you wish to retouch, you can do this by clicking around the area with the tool, If you make a mistake just press the Del button on your keyboard which will undo your last click.
Once you have selected around your area you will get a marque around it.
Now we will be using the Healing brush which is located on the tool bar on the left with this tool we will need to select a sample colour, this can be selected outside the marqued area, but will need to be a similar colour or shade, to do this we will need to press and hold ALT on the keyboard whilst clicking with the mouse on the sample colour.
Now you can start retouching your image by going over the area you selected inside the marque, notice than when you are using the brush it will bring up a cross on the image as well this is where you are sampling from, for best results make sure the cross is always on a similar colour that you are retouching, if it isn't go back to the step earlier and reselect your sample colour with ALT+mouse click.
To get rid of the marqued area once you have finished select the Rectangular marque tool and single mouse click any where on your image, now save you image.
Tip 1.
Hover over tools with your cursor and their names will pop up.
Tip 2.
Tools on the toolbar with arrows in their bottom right corner have different tools grouped with them, to select these tools click and hold on the tool and a drop down menu will appear allowing you to select alternative tool options.
Tip 3.
Always save as your file and keep the original, just in case you need to revert back to it later on.
