Why does my pictures when shot in high apertures have this shaded line?

[whatever]

Whenever I shoot in a high aperture (f10 and higher) I noticed this shaded curved line starts to appear. It's very faint at f10 but gets more prominent the higher the f stops goes. I notice this at night and on all my lenses.

you have a hair on your sensor.

Try to use blower on the sensor, usually it removes non sticky dust.

I was going to say there was an alien on his sensor, but the hair makes more sense.

If it's not a hair on the sensor then you REALLY REALLY need a haircut, and a comb.

Do not use one of those cheap "lens" cleaner blowers with the brush on the end!! There are several good manufacturers that are not that much. Giottos Rocket Air Blowers is what I have. Sold at lots of places online. They have several sizes. Good to keep one in the bag.

I see there's a small and medium. Does it matter which size I get or is that personal preference?

with a hair that large, you can probably turn the camera upside-down, open the mirror, and knock it out. or grab it with tweezers if youre incredibly careful.

The larger one will give you a larger shot of air. I have a couple of each. Either one would be good to have.

Should I also get a good brush pen for maintenance or is the blower good enough?

I would never use a brush pen inside a camera body. Blower or if you feel confident of your skills a wet sensor swab. For lenses a blower, soft brush and a good lens tissue and lens liquid kit should be all you need. I have a lens pen but ONLY use the brush end. Got it for nothing so it saved me from spending a couple of bucks on a brush.

. . . when shot in high apertures . . .

For What It's Worth:
f/11 is a way smaller and lower number, and a way smaller lens aperture, than f/2 is - because f/11 & f/2 are fractions.

f/11 says that the lens opening is 1/11th the diameter of the lens focal length.
If the lens focal length is 50 mm the lens opening at f/11 is only 4.54 mm wide.

f/2 says the lens opening is 1/2 as wide as the lens focal length.
If the lens focal length is 50 mm the lens opening at f/2 is 25 mm wide.

Note too that when using small/low lens f stops focus sharpness can be diminished because of diffraction.

Many inexperienced photographers also don't realize that when the point of focus is way out in front of the camera there is way less need for a small lens opening to achieve a deep depth-of-field.
