Solar artifact?
Oct 16, 2012 16:46:42 #
You can see what I'm talking about in the picture below. It appears to be internal lens reflections casting the shadowy image of the sun onto the sensor. It only appears when the sun is actually in the frame or just outside, moves around depending on sun position and disappears when I shade the lens.
What I don't understand is that unlike the blurry captured image, when seen in the viewfinder, it has sharper focus, appears to be spherical and has bright red dots on its "surface". Imagine latitude and longitude lines on that little sphere - the bright little dots would be at the intersections. It's actually an interesting little artifact :-)
Even though I've had the D5100 several months this is the first time I've shot with these sun angles.
I usually think of "flares" as being soft streaky bright areas in the image.
1 - Is this just a type of flare?
2 - Is this something commonly seen by those of you with years of experience behind the lens?
3 - Any ideas about what in the lens/sensor chain would be putting the red dots on the sphere?
4 - Does sensor or lens dust ever display this way when directly hit by the sun?
(Just realized I should have posted in Photo Analysis - sorry.)

Looks like a sun flare to me, but I'm no expert. If shading the lens made it vanish, then that's likely the issue.
That is one heck of a rugged landscape, tho. Nice shot!

It's solar flare. Now the question I have for you, did you have a filter on the lens at the time you took the picture? It usually happens to me when I have a filter on and shoot without the lens hood on the lens...
Hope this helps.

Same thing happens to me if I'm not careful / shooting without a hood.
I like having a filter on, to put something between the super expensive glass (LENS) and my idiot moves ~ but there is a downside. Flare can / does happen...

It doesn't matter if you have a lens hood on or not. If you are pointed in the direction of a bright light, you can get lens flare. Get into the habit of looking at the image after you shoot it. Usually, by putting your hand in the right place in front of the lens and shading it, you can get rid of the flare.

Some times it helps to wear a hat, hold it out where needed to cut the flare.

It's flare!
Light bouncing around inside the lens and/or filter glass.
Judging by the location of the flare, the sun was somewhere towards the top centre of the frame
You can prevent it by shading the front of the lens.
In the past I've done this using a lens hood, the shadow of my hand or standing in the shade of a tree/building, etc.

What??? It DOES matter if you have a lens hood. That is what they are for. Sometimes it needs some help by holding a hand or hat out even further, but to say it doesn't matter if you have a lens hood or not is just plain wrong. Sorry, but I just don't get your reply.

I didn't say "NO LENS HOOD" You can get flare with and without. You need to look at your image before you walk away to the next one. Just say'n, that's all.

Not trying to be insulting, please read your first two sentences again. I'm just saying, it does matter if you have a lens hood.
I'm glad there are people who are willing to lend a hand to others, without just snapping that they should read their manual. I was just trying to clarify that the lens hood does make a difference. Maybe you and I aren't reading the sentence the same way, but kudos to you for tossing in your ideas.

Of course it matters. If you have been around cameras for any time you know this. If I was misunderstood, I'm sorry and thanks for pointing out that my statement could be taken more than one way.
1. Use a lens hood on your camera, ALWAYS. It will help protect the front element from damage
2. Even with a lens hood, you can still get lens flare.
3. If you don't look through the view finder or check your final image to see what it looks like, you won't see the lens flare until you get home.
I am by no means an expert but I do some teaching. One of the first questions I ask is "How many of you check the LCD after every picture to make sure you have recorded what you want?". Most people do not.
