This is a tutorial on how to make a walk in image.
1. First off Find Your Render. I used A pic I found off of Google >.<
2. Make a new layer above your background
3. Now Use the Rectangular Marquee Tooland make a Selection like this.
4. Fill the area with white.
5. Now Use the Marquee tool again and cut out some of the inside to look like this.
6. Now, while the white layer is selected, press Ctrl+T and Right Click in the transformation area and select perspective.
7. Drag the left top corner down to look like this.
8. Now select the part you want to stick out by using the eraser tool and delete the background around the picture border with the eraser tool as well.
9. Now Ctrl+Click on the white border layer again and erase the parts near the part of the image that is sticking out. Like this.
10. Thats Just about it! You may add a granite background or you can make a transparent background.
