Is this lens flair?

Hi all

I took the photo below of my daughter a couple of weeks ago. You'll notice something in the top left corner where you can see the shape of the aperture blades. You can see the large obvious one but then also the smaller highlights within this e.g. some bits on the swing in the background.

Personally, I quite like it. However, no idea what causes it. Can anyone explain? Is this lens flair? The photo was taken with my Tamron 28-75 and it had the hood on and also a UV filter if that makes any difference. I took a few photos that day and a handful had the same thing on them but never seen it before or since.

The big ones are flare, the little ones are bokeh.

TECHNICALLY, the little ones are "Circles of Confusion".

I thought the "big ones" were called 'ghosting' and not 'flare'. Flare would reduce contrast over the whole image. No?

Thanks to modern lens coatings that are designed with the express purpose of maintaining contrast under these situations, no.

That is also how I would use terms. To me, internal refexions cause 'Ghosting' while light from strong sources just outside the field of wiew may scatter and cause a milky 'Flare' over most or all of the image?

Having searched for ghosting and flaring this seems like a pretty good overview of it all:

Modern coatings are going to reduce flare but they do not eliminate it completely. They also don't change the definition of the term 'flare'. :-)

I am no native speaker, but ...

I think flare is the more general term for any kind of light attributed to scattering within the lens. While ghosting and haze are the more specific terms for visible artefacts and reduction of contrast.

It seems wikipedia uses the same notion.
And the ghosting lens effect filter in photoshop is called "lens flare...".

But others may use different notions.

And btw, it is flare, not flair. Flair has a completely different meaning...

So in summary then it is a result of me shooting almost directly into the sun. Doing a bit of research it seems that could be quite expected with this lens so no problems, at least I have learnt something. Thanks for the responses.

DON'T use UV filters to 'protect' the lens - about the only two filters that cannot be duplicated by the electronics within current digital cameras are polarizers or neutral density. Extra optical surfaces only degrade the image. DO use a lens hood.

Yeah I've been reading about that and have decided to remove my UV filters (although there was one on for this pic taken a few weeks ago). I do always use a lens hood though.

So...I wonder if this is lens flare? I've always assumed that the left hand side of this photo was caused by light reflecting off oil inside the lens....

It looks like some kind off reflection from an element or maybe the interior of the lens. I guess the light source is high up the right side.
