− | + | {{Incomplete|More on the title text. Would the direct sunlight not be a bad choice for taking pictures of the moon, although the full Moons surface is in more direct sunlight thatn anything down on Earth (due to the atmosphere).

[[Cueball]] is trying to take a photograph of the {{w|International Space Station}} moving in front of the sun ([https://www.nasa.gov/image-feature/international-space-station-transits-the-sun example]). He has his camera with a long lens set up with a fixed setting to keep it still while he contemplates the best way to get the photographs he wants. | [[Cueball]] is trying to take a photograph of the {{w|International Space Station}} moving in front of the sun ([https://www.nasa.gov/image-feature/international-space-station-transits-the-sun example]).

This is why Cueball is using a {{w|Astronomical_filter|solar filter}}, which makes the sun look orange instead of white as shown in the second panel. |
Digital cameras need to determine the color temperature of a photograph to correctly display colors. This is done using the {{w|Color_balance|white balance}} setting. The joke here is that Cueball selects the "direct sunlight" option, as he feels it is the option that best suits his unusual situation of directly photographing the sun, even though the "direct sunlight" setting is intended to be used for photographing objects directly illuminated by the sun and not for the sun itself. | Digital cameras need to determine the color temperature of a photograph to correctly display colors.

The light from an object illuminated by "direct sunlight" is, in fact, ''indirect'' sunlight when it reaches the camera sensor; so when photographing the sun itself, the camera receives sunlight that is even more direct than "direct". | The light from an object illuminated by "direct sunlight" is, in fact, ''indirect'' sunlight when it reaches the camera sensor; so when photographing the sun itself, the camera receives sunlight that is even more direct than "direct". | ||
− | The use of a solar filter influences the color temperature, so "custom" would probably be the correct option here. A camera using the "custom" option usually requires you to focus on a white or gray object first to determine the correct setting. | + | The use of a solar filter influences the color temperature, so "custom" would probably be the correct option here. A camera using the "custom" option usually requires you to focus on a white or gray object first to determine the correct setting. The camera depicted in the comic seems to be a {{w|DSLR}}, which would be able to capture in {{w|raw image format}}, allowing the user to adjust the white balance afterwards in software. |
The title text is pointing out that the sunlit side of the moon is also in direct sunlight, which is why we are able to see it, and so "direct sunlight" would actually be the correct setting in this case. | The title text is pointing out that the sunlit side of the moon is also in direct sunlight, which is why we are able to see it, and so "direct sunlight" would actually be the correct setting in this case. | ||
