In the photo below (which is the full, original photo without any cropping or color adjustment), we see two large purple orbs. They cannot be the result of lens flare, as the place photographed is a dark place, and no bright lights were facing me when the photo was taken. These orbs also cannot be dust, as they are way too big to be dust. Those who claim that dust in front of the camera can cause orbs say that dust orbs cannot be larger than about 10% of the original photo size (and when you actually photograph dust raised in front of the camera, you don't get dust orbs larger than about 5% of the original photo width). But these orbs are both more than 25% of the original photo width.
What is very interesting about the bottom orb is that it is clearly behind the concrete wall, which was about a meter from me. The whole bottom part of the orb is blocked by the concrete wall. This is additional proof that this orb could not have been a speck of dust near the camera. For similar photos, see my posts labeled "air orb too distant to be dust" and "air orb to large to be dust."
