First, the castle is chopped out of the original source photo onto a new canvas 10 x 10
step 8 of 15
Background sunset is added after raising resolution to 120, then castle is scaled to a size to fit on beach, stretching it slightly taller.
step 9 of 15
Since the castle will not have bright lights on side of viewer, highlights are removed by using the cloning tool. Color changed are also made to both the castle and beach scene to get sand colors to match as closely as possible. Color/balance and hue/sat tools are used for this.
step 10 of 15
Here, a gold/red highlight on sunset side of castle is added using the brush tool, Also, using clone tool and burn tool, the sand is 'roughed up' to look like sand has been walked in.
step 11 of 15
Texture/sandstone texture is added now and background hills opacity is slightly reduced with a very low airbrush spray.
step 12 of 15
Bucket and shovels are chopped out of their source and added. They are scaled down and moved to right foreground, then chopped with eraser tool. Shells are also chopped, scaled down, then will be added to bucket. Burn tool and color/balance tools bring colors into same range as sand already there, then clone and eraser tools blend edges together.
step 13 of 15
Shovels and bucket seemed to look transparent, so a dark filter is added to take away the opacity. Also, at this point, dark doorways in castle have colors of background added to give a more open look to the castle. Colors are added using brush tool, then smudge tool to blend edges.
step 14 of 15
Finally, seagulls are added after chopping, given a small amount of gaussian blur, then after merging the layers all together (merge visible) filters in dark brown and gold are added, with opacity reduced to 20%
