Create a new layer, and add a levels adjustment to brighten
Below the "sektech layer" add a new layer then
alt+backspace and it will become white - name it white
On this White layer, select the eraser tool with a brush that is like a dry media brush #63 or close and set the opacity to around 15-25% and begin to brush away on the white surface to let the image below come through.
Enjoy this process and play with lots of photos. Some images become magically transformed and others find their way to the trash bin or different processing. This is so much more fun than a plug in!
