Solar artifact?

I thought for a sec they had found some primitive tools and cave paintings on the sun :)

Looks like sun flare to me. Did you use a lens hood to prevent light from entering the lens.

Now that you know what to do next time, the image itself is pretty easy to fix in PP.

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.)

That's awfully low for a flare, and there is usually more than one... maybe it's an "orb"! :wink:

It's easy to see if you have flair, especially if you are using a tripod. You just walk in front of the camera and look for light sources, or just direct light, on the lens. On movie sets, we have all types of flair correction, and camera assistants whose job it is to eliminate flair.

Basically, you always want your lens in shadow. In stills photography, a well placed hand works wonders. From the shooter's point of view, you just move your hand so that the tip of the lens is in shadow. A clipboard works great too, amongst other things, like foam core.

Whoop de do... Nice shot, wonderful location, this one is an easy retouch.

However, anytime the sun is anywhere in front, you gotta start watching for this. If it was worse or more extensive, it would be a difficult or impossible retouch.

Follow PhotoArtsLA direction on this! And get a couple of assistants to camp with you in the mountains like the ones in his avatar! ;0)

Artifact? I've always thought that an artifact was something made with skill by man. But this use means that the whole thing (Artifact) is a mistake. And not made by man. Wouldn't the anomaly you discuss be better called an anomaly?

Thanks for all the comments. Definitely a flare. I posted the question before processing the rest of the pictures from that trip. Had I seen the pic below, I wouldn't have had to post the question.

Well, I actually saw it in the viewfinder and tried to move it out on some shots. But the bigger issue here is that when driving through scenic country with a spouse who is not an avid photographer, I tend to do some careful framing, grab a dozen or so shots and move on without review on the LCD. This, in an effort to minimize the impact of saying, "Yes" the next time she asks, "Do you have to stop again to take more pictures?" (But I don't suppose any of you can relate to that! :roll: :lol: )

Yep! Not an artifact. Got there as the result of a lack of skill. An accident in fact. Bet you've got that skill sorted now though.

Yes, several. You want to see them?

They just move around the bottom of the frame opposite from sun position at top. I assume that the direct sunlight is doing some extra internal refractions and reflections that create it. Like I said in my first post, It actually is in pretty good focus in the viewfinder. (I've actually tried to take a picture of it in the viewfinder with another camera, but it just doesn't work.)

Sure would like to see more. Very strange. Always the same size/shape etc?

It looks to be a flair but it looks like it was caused by a drop of moisture on the lens because in both photos it is in about the same place and shape. It is a dot and does not flair out from the edges. It really appears to be caused by something on the lens to me. But.... it could be an orb. :-D

That placement in the two pics is coincidence. After I figured out what it was I found I could recreate it at will by not shading the lens whenthe sun is slightly outside the frame. It does move around in the lower quarter of the frame in line with suns movement around the top.
