Trick Photoshop

I have posted a lot of tutorials, but it seems I have never posted one on the Quick Mask for creating a selection. Quick Mask can be used for selecting a portion of an image or for cutting out an image for putting on another background. I have been asked to post a tutorial on the Quick Mask.

Step 2 : I have opened this photo in Photoshop. I intend to cut out the flower with the Quick Mask. There are various ways you can begin creating a selection.
Step 3 : You can use the Lasso Tool or the Magnetic Lasso Tool for creating a selection. I have chosen the Magnetic Lasso Tool and not the Polygon Lasso Tool even though it is highlighted.
You can use it too of course.Step 4 : Now click a point with the Magnetic Lasso Tool. Then click and drag adding points. If you make a mistake, hit DELETE and it will delete the last point, then carry on till the entire portion you want is selected.Step 5 : As soon as you return to the last point a selection will form.
Step 6 : Click the Edit in Select Mode button or press 'Q' on your keyboard.

Step 7 : As soon as you click the Edit in Quick Mask Mode button, a reddish color will fill the canvas except for the selection.
Step 8 : Now zoom into the image. You will see that there are imperfections in the Mask. Some portions may have been left out of the Mask or some portions included that you do not want.
Step 9 : To add to the Mask paint with Black (Foreground Color) to substract from the Mask paint with White (Background Color) with the Brush Tool.
Step 10 : Click on the Brush Tool. To make the Brush tip large press ] (right bracket key) and to make it small [ left bracket key). You will need to change the brush size from large to small as you paint.
Step 11 : Paint out the imperfections with Black when you want to add areas and with White when you want to substract from it.
