Before and After

Step 1
Open up these two pictures in PhotoFiltre. Human and Wolf

If you want to use your own pictures, make sure the widths of both pictures are the same or similar in size.

Step 2
Go to the picture of the girl and go to Edit >> Define Pattern.

Step 3
Now with the picture with the wolf, go to Image >> Duplicate.

Step 4
On the Duplicate image, go to Filter >> Color >> Gradient and set your settings as mine.

Select All and copy the entire image of the gradient.

Step 5
Go back to the original picture of the Wolf and go to Edit >> Paste Special >> Assemble >> Right.

Select All and copy the entire image of the wolf and gradient together.

Step 6
Go to the image of the girl and go to Edit >> Paste Special >> Image with Linked Mask. The wolf should now appear. Move it around so that the Wolf’s eyes are on top of the girl’s eyes.

Step 7
Now using the Clone Stamp Tool, erase away the harsh edges from the Wolf picture.

Step 8
Add effects and you’re done!
