selection tools
The top one is a pointer. This is not for selection. You will see how you need it.
The second one called marquee tool. You can see a small dot in the right bottom of it, right click it and find out what types of marquee tools we have.

Exercise 1 :

- Click menu Selection -> deselect. What happened?
- Click again Selection -> reselect. What happened?
- Click Selection -> inverse. What happened?
- Click Selection -> inverse to bring back the original selection.
- If you want to crop or lessen the area of selection, push button “alt” while doing the second (correction) selection. See this video clip.
- In opposite, using “ctrl” button will add the existing selection. Try by yourself.
Exercise 2 :
- Open the windmollen image in your Photoshop.
- Make a good selection on the biggest mollen.
- Do smoothing of the selection by using “feather” = 1px.

- Make sure that the new layer is selected. Click the “pointer”, then use your mouse to move the second biggest mollen to a place you want.
- Save in PNG, JPEG, TIF and PSD. Close all, then open each copy again. Do you notice what is the different between each format?
Exercise 3 :
