This is what the dodge tool looks like on page, you must hover over it to select it.
You must then select the size of the brush you want to use, the panel above is the sort of panel you should use.
Move o the size tab to use a smaller brush or bigger brush.
For example, here you can shine somebody teeth. quick, easy, simple.
I will use this tool to make pictures look better and more professional. I could use his to make somebody's face look better for advertising etc.
This is a really good piece of work that fulfills the task completely. well done.
T: Perhaps consider showing an example that you have made using this tool.
