Aperture reflection or glare?

I was looking at this selfie taken last year and noticed an aperture shaped glare on the glass. Why didn't the reflection show up in the photo itself? The image was reflected off of my trike's mirror. I would think there would be an aperture shaped glare larger in the photo somewhere because of this. Any ideas? :confused:

Quite normal in the given situation. Remember that, when you've got TWO reflective surfaces directly facing each other, you automatically have a so-called "endless mirrors" effect (that is, multiple, concentric reflections between these two glass surfaces).

Nice photo, anyway...;)

I'm not surprised to see this...I just think that since it shows up as a reflection inside the lens, then why didn't an aperture shaped glare show up in the photo outside of the lens? And thanks for the comment! ;)

I don't understand what you mean. :confused:

My logic is telling me that the aperture glare is between the subject and my sensor so it stands to reason that it would show up as a glare spot in the image. Oh well....

The location of the reflection of the aperture will depend on the angles of all elements - the lense, incident light and the mirror. You can try it out easily by shifting your position wrt. the mirror and incident light and the aperture will shift.
