About the Image(s)
Here is another image I took of Blarney Castle quite a while ago, May 2013. This was during a trip to Ireland.. The image was taken with a Panasonic GH2 with the stock 18-45 lens with th focal length set to 14mm. The aperture was f/6.3 and the shutter speed was 1/500. The ISO was set to 160. The Panasonic GH2 is a mirrorless micro 2/3rd body and is a little noisy, even at this low ISO. It was an overcast day and on the original image the sky was completely blown out. Photoshop 2020 has a feature that does a one-step sky replacement, and this seemed like a good image to experiment on. The sky I used was from an image I took in November of 2019 in the Antelope Valley near the ‘Kill Bill’ church. This image was taken on a Nikon D7200 with a Tamron 18-400mm lens set to 50mm, the aperture set to f/7.1 and the shutter speed set to 1/100. The ISO was set to 400.
I did a straight sky replacement in Photoshop using the Edit/Sky Replacement option and adding my sky to the library. I had made some minor adjustments to the sky using a Camera Raw filter and saving it as a jpg. Interestingly this added a number of layers and did a pretty good job. I then went in with a few tweaks. For the castle, I added a sharpening layer to bring out the stones a bit more. I removed a security camera and its power supply which was in one of the windows. The sky replacement added a curves layer that was supposed to match the colors of the sky with the foreground. I could really see where it was doing much, so I used a little trick I learned from a YouTube video, duplicated the sky layer and applied a Gaussian blur to it with the slider all the way over. I then inverted the mask so it was the sky was masked instead of the castle and changed the blend mode to overlay. This takes the sky colors and applies them to the castle. I then used the opacity to adjust the amount of the effect. I then cropped the image on the top and right. I then applied a denoise filter to the sky, since it seemed a bit noisey.
I also did some minor adjustments to some of the masks where there was some haloing, particularly around the crow in the sky.
I am attaching the original image for reference.

I have so many questions regarding the sky replacement. First, the sky you chose is a good match in tone for the dark castle. My judge's eye sees several issues. First I would be interested knowing the pixel density of both the castle and the sky. The sky seems to have a bit of noise running throughout. The castle appears to be at the 300 count, but the sky seems to be lesser. Do you know the actual pixels per inch of the sky? Then as I look at the image the right side of the castle has the evil telltale halo that gives away the fact that the sky has been replaced.
Even with these issues, the image is still quite powerful and dramatic. I assume you have framed it.

It is a neat idea, but I think I'll be trying to get it right in the camera for a while longer.
But that is just my opinion.   Posted: 02/10/2021 15:21:21
My comment is that the sky is taking too much attention from the castle which is the main object. I am not sure if it will work, but you could try to use the mask of the castle and invert it and then darken the original sky. Maybe you get some nice clouds that will give you the dramatic effect you are searching for? Converting to B&W is also an option to consider.   Posted: 02/14/2021 06:14:42
