This creates the perception that there is a distance between the background and the subject you are shooting. When you are shooting with a wider aperture, you are able to focus more on the person or thing you are shooting and the background becomes a bit more blurred.
When a photo is taken particularly using a small aperture (to make sure everything is in focus) things appear to be more two dimensional so there is no concept of space. Why then on a photo does it show up as a big round ball? It all has to do with what photographer’s refer to as the ‘circle of confusion'. The other thing is that the dust particles you see floating through the air are incredibly small. You know when you have a beam of sunshine coming through your window and you can see all the dust particles in the air? Sometimes it is horrifying to think about what we are breathing in. Where these two cross over, if there are any dust or moisture particles in the air, the camera cannot properly focus on them (more on this below) and it appears as an orb.ĭust is small and difficult to see with the human eye if it is not illuminated by some sort of light source. When the flash fires, the area that it is lighting up usually crosses over with the area the lens is taking a photo of. This is why smartphones tend to pick up a lot of ‘orbs’ in dusty old buildings. This means the entire area that the lens is shooting is going to be lit up directly by a flash. In all smartphones today, the flash is directly next to the lens. This often means the object closest to the camera is in focus while the background is blurry). (This is what you use a wide aperture for, meaning the opening will be larger. It's so that the cameras are able to take a picture of a beautiful landscape and everything will be in focus, not just the object closest to the camera. It is only open a small amount so that it can have a greater depth of field. Aperture refers to the hole in front of the lens that lets in the light. These cameras usually shoot with a small aperture. When the flash fires, the shutter on the lens opens in order to take the photo. In a smartphone or a regular digital still camera, the flash sits pretty much next to the lens of the camera. They are common in areas where there is a lot of dirt, old buildings (which most haunted locations are) and of course if it is raining or there is moisture in the air. In a nutshell, a dust or moisture orb appears in your photo because the flash has reflected off a particle of dust or moisture. This is the most common explanation for an orb and is particularly common on photos that are taken with smartphones. Here is an easy guide to help you distinguish what kind of ‘ORB’ you are really dealing with and how your camera is playing with you, and there is nothing paranormal about them! Dust and moisture ORBS Yes in a lot of cases it is in fact dust that has caused the ‘ORB’ but there is also other natural phenomena that can also cause orbs thanks to your trusty camera. Whenever someone presents a photo on social media of an ‘ORB’ the usual response from people is that it is just dust. Over 50% of the votes were for dust and this didn’t surprise me. There were 3 options to choose from – Spirits, Dust and Other. I recently saw a survey online where a group was asking its followers to choose from three options of what causes ‘ORBS’.
