I have a black dot in all my photos. I ruled out it my lenses because I changed lenses and it is still there in the same spot. I ruled out that it is my LCD screen because I imported them on my computer and looked. It increases in size when when I open the aperture more and decreases into a small dot when I close it. I don't know what it is, I know it's in the camera, but I don't know if it is the mirrors or the censors, I think it might be the mirrors since it changes with the aperture. But I'm still unsure. Has anyone else had this problem? I like to shoot in sunlight which is dangerous, but I usually do it with clouds or at dusk. I think it might be be a spec of dust since I shoot in the forest a lot. Here are some photos. I would appreciate any feedback thank you guys!
Right here on the left side

This is a more open aperture
Here's one where it's right on my girlfriends lower right cheek :/
