Purple spot on image - what is it?


 
 
Can you see the purple spot at the base of the monument? What caused this?

  I see the different color in the stones/bricks. I don't see what I'd call a spot. Unless you could upload a photo more zoomed in on the area.

Thanks, Gregory. Here is another one - I cropped tighter. The purple spot (or area) is a on the monument, a bit above the middle.

  My first guess would be something on your lens, causing some kind of light diffraction? I see 3 spots in the clouds (to the right of the monument, in the 1st photo) that suggest your lens may have splatters of something on it?

  Chromatic aberration makes a purplish color like that. Usually if something on the lens shows up, it's on the side of the aperture blades closest to the camera, like sensor dust shows up. So it could be a finger print on the rear elements. Or check for mold inside the lens.
The spots in the clouds look like something on the sensor.
You can always make a white screen on your monitor and take pictures of it at small apertures and see if they show up. That's an easy way to check for dust on the sensor.

  Thank you both. I'll try cleaning it once more and see if I can get it. If not, then it's time for a professional clean.

  Jeff, I'm sure you are right. Because I would never let my lens get dirty or smudged. Nope. Never. That's my story and I'm sticking with it.

So aliens it is.
