What causes these streaked rays from light sources?

In my opinion that "flare" is caused by a dirty lens. I'm guessing you attempted to clean it, by using a wipe, but failed to properly clean it, which is why the flare has directionality. Try using a ...

What is "veiling glare"? How does it affect my photos, and how can I avoid it?

Veiling glare is light that's not intended to be part of the image, per se, but ends up on the recording medium (film or sensor) anyway. It's caused by reflections and scattering of light by optical ...

What creates a bright green orb "lens flare" with silver or metalic dots on it?

It's a reflection of the image of the sun in the sensor, with the PDAF focus pixel covers reflecting brightly. See: https://www.metabunk.org/orbs-with-dots-focus-pixels-reflection-in-sun-reflection-...

What is the cause of a dimmer image of a light source in a photo?

That is most likely the result of an internal reflection between different elements in your lens. Modern coatings can reduce and/or eliminate a lot of internal reflections, but all bets are off when ...

What are these strange lines that are visible at sunset?

It's called lens flare. Light from the sun that is just out of frame is striking the surface of your camera's lens or surrounding housing and bouncing around inside the lens. Some of that light is ...

That is an internal reflection... if you have a filter on the lens remove it. It is common for the front element of a lens to be multicoated to reject/reflect light that might cause flare, and that ...

Why is there a secondary image of a light bulb in my image?

It is a lens flare, a secondary and dimmer image of the bright light bulb caused by a part of the light not making it straight to the sensor but reflecting around inside the lens first.

What does lens flare from a catadioptric (mirror) lens look like?

Catadioptric lenses are lenses that combine both refractive and mirror elements. A simple mirror lens with no refractive elements is not a catadioptric lens. I've never seen a commercially available ...

How can I take a picture of a Christmas tree without lens flare around the Christmas lights?

The "diffraction spikes" you are seeing is the result of using a narrow aperture. Some folks refer to such effects as "sunstars." The light travelling through your lens' aperture diaphragm is ...

Why is the aperture of this old lens showing as centered blue glare?

This looks to me like reflection from the sensor to the rear element and back again. Film is less reflective than digital sensors so some older lenses have either no anti reflective coating on the ...

Why is the aperture of this old lens showing as centered blue glare?

Yes, that's because the adapter you're using - it is not possible to adapt Minolta MC/MD lenses to Canon EF while retaining focus to infinity without an adapter that has corrective optics (and ...

X100 Rainbow glare on artificial light

It looks like the lens is greasy. Probably some condensation on the lens. If it is condensation, it could be on the interior of the lens. See if there is a lot of humidity, or if your camera has moved ...

What exactly is this light artifact/flare?

That's just an ordinary flare. It is cat-eye shaped probably because it is reflected from the edge of the lens element - edge of the lens mechanically blocked part of the otherwise round shape. Green-...

ND filters issue - washed out pictures

I believe this is due to a light leak entering between the two ND filters, and the one in front (farthest from the camera body) does not have a light-blocking foam gasket. Light coming in through the ...
