View Great Kills Park in a larger map
The first thing I did was open the picture of my drawing. I then opened my picture of the Great Kills Waterfront. The picture I drew was based on the picture. Then, on the layers window, I went under mode and chose soft light which blended the two together.
For this I first opened my picture of the waterfront. I then opened my drawing as another layer. I turned on Alpha channel and I had to crop my drawing because it was a little big. Then I used to moving tool to center it. I then went onto the layer window under mode and chose gradient merge and it merged the two pictures nicely so you can see both the bridge and my drawing.
