The antenna is set up, and I want to show it off and send QSL cards, but I don't know how to extract the image.
Are you having trouble using fountain pen tools? Is it too complicated to choose freely? Are you finding magic wands too cumbersome?
However, once you have mastered both opportunity and timing, all problems become easily solvable!
(P.S.: Please read the entire document first before taking pictures, otherwise it may cause some inconvenience.)
Therefore, I chose to shoot at night because the antenna is white (of course, the antenna is black or colored during the day), which creates a high contrast.
Once the contrast has been increased, you can use the "color range" tool.
Based on the experiment, I obtained the following parameters:
Color: Shade; Tolerance: Approximately ±30%
Of course, you can fine-tune the contrast if it's too low or too high.
[Before using a specific color range, it's important to first adjust the environment appropriately. For example, I used the Magic Wand tool to remove the surrounding sky. However, selecting an area freely is even more recommended.]
When encountering metal connectors with low contrast, it's necessary to bypass them. Manual trimming will be performed later.
[After removing the background, drag the up and down scroll bars to browse and check for any missing or extra areas.]
And then there's the issue of large antennas.
For example, with this antenna, we couldn't take a wide-angle shot, and the construction window period had already passed, so we could only do patchwork.
Align the pole and antenna body. After completing the puzzle, you can adjust the hue and saturation to correct color differences, or use gradient effects, or mixing options.
[Strongly recommend that everyone use the mixed option]
When I choose the "hue" option in the mixed settings, the results are optimal.
Finally, subtract the corresponding values from the diagram below as well.
Regarding aerial shots, the clarity and visibility can be affected by the camera angle, sometimes resulting in blurry or even missing images. This can be remedied by copying and pasting to complete the image.
(If you're feeling bold, you can simply delete it. The issue is that the card design or resolution isn't sufficient, so it hasn't been printed yet. Of course, I don't recommend doing this.)
Regarding the issue of antenna matching, I recommend taking a complete image of the antenna itself and then extracting only the antenna body. This will minimize the need to match colors at the connection points.
When encountering such strong light interference, the only option is to copy and paste to fix it, which is a basic Photoshop technique.
(Regarding this image, I actually know that it's simpler to use a pen tool to secure the wind rope, but I wanted to show you an example of a special situation.)
After applying the filter, open the color range settings. Color: Shadows, with maximum tolerance (i.e., select all pixels).
Preview the selected area by choosing grayscale; this allows you to view the image in a larger format.
Check for white spots in the following areas where images should not be present.
If you have it, immediately remember its location and click "Cancel" to exit. Use the selection tool to delete it; otherwise, it will affect the card's appearance!
(As shown in the image, those scattered white spots must be removed)
Examples of qualified individuals are shown below.
Final result
Then, it can be used in various places.
Tolerance regarding the Magic Wand tool:
Buildings: 50% (It's recommended to directly select or lasso, or use other methods like the pen tool. This tolerance already has destructive properties.)
General: 30%
Clear sky: less than 10%, ideal (with clouds, around 15%, ideal, or eliminate the clouds separately)
Adjust based on actual results, while minimizing damage to the original image.

Before taking a photo, be sure to check if AI camera mode is enabled; that's what it is.√10These are the types that manufacturers don't use, and they are also enabled by default. They often generate strange pixels, making a clear image blurry. Especially those that need to be heavily edited in Photoshop!
If you're not sure what an AI camera is, be sure to search online and check if your phone has this feature enabled!
