Adobe Tutorial

There is a wonderful addition amongst the rich set of features in PSE 9 - Layer masks. This was something which was missing in PSE 8. It is a wonderful tool which helps in achieving a lot of good results in different editing operations. This tool is specially helpful for people like me who arent that precise in selection tools like lasso,quick selection etc. However, are more comfortable with the paint brush and eraser.

In this tutorial, I will be using Layer Masks to move one object from one image and place it on other precisely without using any of the other selection tools in PSE like Lasso, quick selection etc.

I have the following two pictures : one is butterfly on a white flower and other is a lady bug on a pink leaf. Now I want to place the lady bug from the second picture on the flower leaf of the first picture, next to the butterfly.



1. I opened both the images in PSE 9 Editor.

2. Now I keep the image of butterfly in display in the editing workspace.





Select the Move tool from the tools bar and drag the ladybug image from the project bin below over to the butterfly image in the workspace.



3. Now as you see in the image below, the lady bug image comes over the butterfly image occupying a lot of space. Also you would notice that there is a new layer formed in the layers palette which is that of the lady bug image.


Just drag one of the corners of the lady bug image inwards to reduce its size.

Now one can rotate the image of the lady bug by dragging the corner of the image keeping Control key pressed and revolving it through the corners like this.



Click the commit green button when you think that the orientation is correct.

4. Now select the lady bug layer in the layers palette and go to Layer> Layer Mask> Reveal All.



As you do this you would see that there is one white mask that got created in layers palette.

5. Now select the Brush tool from the tools bar and black color selected as foreground color in the color swatch (as shown below). Now brush over the rest of the area of the lady bug layer leaving just the lady bug. This will remove the pink and green background of the ladybug in the layer.



As you click and drag the mouse with the paint brush you would notice that some black color gets painted in the white mask in the layers palette.  And you would see the pink leaf disappearing.

In case you mistakingly paint any unwanted area or some extra area, you can correct it by changing the foreground color in the color swatch to white and paint over that area again. So you can keep switching between black and white foreground colors in the color swatch to correct your selection.

Also for best results, zoom the image to 200-300% and reduce the brush size when you brushing around the corners of the lady bug to get precision.


Once you are done, select zoom tool and right click -Fit to screen.


6. Now select the move tool again and move the lady bug over the white flower and change its orientation as per your needs. You may transform it using Control+Shift+Alt and dragging the corners.

Here is my final result ;




Layer Masks can be used in several other workflows like selective editing in a picture or applying filters to some part of the image etc.

Hope you would find it useful too.

Quick selection is a great tool for selecting objects in any image. It intelligently selects the object distinctly from the background by detecting the brightness, contrast and tonal changes along the objects and their backgrounds. It takes just a little mouse drag with in an object to select an background.

For example : for the image below I just dragged my mouse from point A to point B for selecting the whole apple instead of moving my mouse along the edges of the whole apple which we would require for other selection tools.


This is how my object was selected moving my mouse from point A to B (Please note I increased the brush size to 35 px from options bar after selecting the quick selection tool for making this selection) :



However in the above image, there is good contrast between the object to be selected and its background. So we did not need to train our quick selection tool. But for getting better results in minimum time when there is not much great color difference or contrast between our object and background, it is recommended that you train your quick selection tool.

So in an image like below, where there is not that great color contrast between yellow flower and its background, we would train our tool.

So if I move my quick selection tool from point A to B to select the yellow flower, here is what
I get as selected :


However I did not need this extra highlighted(green) part in my selection(as shown below) which was selected when I moved my mouse from point A to point B. But since there is a low contrast between the orange and the yellow here, this area too got selected.



So instead of selecting my flower in one go as shown above, I follow the steps below to get my needed selection :

1. Select a very small part of the yellow flower as shown after selecting Quick selection tool.


2. Now I will press Alt key and keeping it pressed, I click and drag my mouse over the area I did not want in the selection. So  I brush my mouse over the green highlighted region shown in the second last image.

I also notice that as soon as I click Alt key my mouse cursor changes from "+" to "-" as it tell what area not to select.

Once I am done with that I leave the Alt key back and again move my mouse from point A to B as I did earlier and here is how I get my desired selection :


So here I have trained my quick selection tool not to select what areas of contrast. So if I had the similar background around the whole flower, then I would just drag my mouse once along the boundaries of the flower to tell my tool about the low contrast areas which I do not want to select.

Also keep in mind that if you have a large and random objects to be selected then you should keep subtracting the wrong selections you make as you sweep and not to defer the subtraction task in the end. This trains my tool at every step of selection and tell it what "not" to selection as it goes ahead.


I hope you find this tutorial helpful!
