In this Adobe® Photoshop tutorial, you will learn some new techniques to blend or overlap two images using Layers. It is necessary for the reader to have some basic knowledge of the various tools used in Photoshop. This tutorial is best suited for semi-Advanced Photoshop Designers. So let's move in to the tutorial now.
First thing you will need is 2 images. Make sure they are both in the same resolution and color-space (RGB in this case). Open both these documents in Photoshop.
We will want to combine both images into 1 .psd document.Let's see how this works. Select the move tool "V" key. Drag one image into the other window and a new layer will be created automatically with the new layer on top. To center the new image in the window hold down the Shift key while dragging.
The next step is to create the layer mask.Click on the add layer mask button. This will create a new layer mask. A layer mask is transparent. When you paint black into the mask it allows the image underneath to show through. Where it is white, the underlying layer will be hidden.
Press the "G" key to select the gradient tool. Make sure the fore and backgrounds are set to black and white. "D" key. Select linear gradient and foreground to background. Now drag the gradient diagonally across the image.
You can see the gradient in the layer thumbnail and the result on the image. Where it is white, the top image shows and where it is darker the back shows through. Experiment with different angles. You may also use any of the brush tools on the mask. Black will "paint away" the image and white will "paint it back". Use a soft brush for best results.
For an interesting variation change the layer blending mode to multiply. This makes the top image appear as if it is a reflection in the glass on the clock.
