Photoshop blend modes

            Some tools and methods I learned was "Rectangular Marquee Tool" which I didn't know about and I didn't know it can copy whatever I select. I also didn't know about the blend modes. The blend modes also have a percent of opacity. 

I also can use this on another visual design task to make something look like it was fading or a shadow, black and white or also make a picture transparent or have the same colors as the background.
