In this first print, there was clearly a yellow colour cast. There was also many scratches and signs of deterioration as well as noise, which may have occurred as a result of scanning the image.
To remove the color cast, I used the curves tool in order to bring the reds of the image down. Then using the dust and sctratched filter as well as the clone and patch tools, I filled in parts of the image that were missing. Next, in order to remove the noise, I used the denoise and despeckle filters. Using the high pass technique, the buildings were sharpened, especially areas that were effected by vignetting. Finally, a 1px Gaussian blur was applied to soften the image and remove any remaining noise.
In the image below there are two main things that need fixing - the crease down the middle, and the bottom left corner, which appears to have deteriorated.
Using a variety of healing tools, including the healing brush and cloning tools, the crease in the middle, as well as the corner can be restored. I have also made some adjustments to the image, for example, being an overcast day at the time the photo was taken, areas of the building look washed out. In order to correct this, I have sharpened areas of the image, especially the plants that are growing on the building.
The following image has clear signs of preparation for display (crease and small holes on top) as well as a decrease in saturation due to its antiquity.
I used the clone tool to remove these marks. Adjustments to the overall image were then made, including vibrance and saturation increases. The clouds in the image were also sharpened for a greater illusion of depth.
