As the partial lockdown in Germany due to the coronavirus and the release of Photoshop’s new neural filter “colorize” almost coincided, I had time to try and see what the filter can do. Here is an example of a color photo of Frankfurt taken just after nightfall. The original is shown at right above, the de-colorized version below, done in Photoshop. The neural filter then created a new version of the b-w picture adding computer-generated colors. See for yourself and let me know what you think.
This is what you can do by applying Photoshop’s content aware filling tool a couple of times to the same image.
