Can some one tell me why these dots kept popping up? What can you do to stop
them? This was done on a Fuji s2 f2.8 for 1 second.

Blow the candles out and I'll bet the dots will go away! It looks like there may be a filter over your lens or maybe the lens elements themselves are reflecting the candle light.
This doesn't happen in all pictures you take does it??

Hope this helps!

Lens flare...same effect as shooting into the sun.

Happens all the time, especially with birthday candles on cakes. But the combination of focal length, number of lens elements, front element diameter and the size of the flames created a pretty severe case!

No, it only happened in these. The first 2-3 shots were under exposed and it didn't do it in them either. When I started getting close to the exposure is when they popped up. I knew they were from the candles I just didn't know how.

It's a Nikon 35-70 f2.8 (the expensive one) same EV all the way through the zoom. I do have a filter over the lens and that may have done it.

This is interesting. At first I thought it was lens flare too. But now that it's come back up I thought, well, what else could it be? If you look more closely you'll see that there is no correlation to the dots and the candles. I mean, for every candle facing the lens there should be a matching spot right? There isn't. Not even close. So what else could it be? I thought maybe it could be from moving the camera after a long exposure and not having the exposure actually be finished but I can't find a relationship with the dots to candles AT ALL... First thing Monday morning, I am at a loss. Anyone have any thoughts?

Dave,

When I look at it, I see reflections of the candles. But of course, they are opposite on the lens...left is right, right is to the left.

Ah, I see it now...interesting...I've never encountered it with multiple sources before so never really thought about it.

Thanks for teaching me something new today!!!
