Steve DeMott Loc: St. Louis, Missouri (Oakville area)
 
My wife and granddaughter were raking and playing in the leaves. Grabed the camera and started shooting. After downloading I notice a semi-transparent ring lower right. Any ideas where this might have come from? At first I thought it might be a double exposure or something on the lens. However, It's on 16 consecutive frames of the 91 I took with-in an hours time. The ring seems to be stationary and in the same line as the green table in back. I took 7 shots before and about 70 more after.

Lots of clouds & and bright. Nikon D750 with 70-300mm 4.5/5.6 VR lens @ 170mm. 1/1250 sec, f/5, iso 2500. Shots are straight out of camera with no post processing. I was sitting under a gazebo with no screens.

Thanks for stopping by and thanks for your help

The ring has a fixed position relative to the table but not relative to the edge of the image frame. Is that a glass topped round table ? Notice that hot spot break in the foliage, above and behind the table ? That narrowed light source is probably there during all three shots even though the camera position doesn’t show it in the first two shots.

I don’t know about the elliptical ring, but if I may: the last shot is unfixable because the focus is on the foreground leaves instead of the subject, but in my opinion, the others can be improved dramatically by just some basic post processing of brightness and contrast adjustments. You may also wish, if you agree, to change some of your in-camera image adjustments so that your raw or JPEGs require less processing. I’m just viewing these on an uncalibrated IPad, but with your permission, I’ll post/show you what I mean, until those more skilled offer more sophisticated advice.

...most likely culprit is that table...?

Two rings can be seen clearly in shots 1, 3 and 4, but only 1 in shot 2. I have no idea as to the source, but since the table appears not to have a glass top, I would doubt that is it.

Do you have a protective lens on? As others noted, this ring seems to be associated with the table... it is not something in the camera.

More seriously, though, after looking at it more carefully, I notice that you zoomed in a bit between frames 3 and 4. The halo actually gets sharper as the background bokeh gets more pronounced in frame 4. The table cannot be the source, as it would not change the halo with zooming, and the angle is wrong for any reflection. What it most probably is, is that you were holding the camera at exactly an angle that the sun was hitting the front surface of your lens (or UV filter, if you used one), and cast the reflection into the frame.

Did you see the ring in your viewfinder? To check if it is a reflection or cast image from the glass table top recreate the shooting situation by setting up your camera at the same spot at the same time of day when the the sun is out to see if the ring is again visible in your shot. Then remove the table from its location to see if that changes anything.

The foliage will be very different. The sun position will be different, It’s unlikely the camera position is accurately known. IOW forget it.

Since it looks like a projected halo, it could even have been the sun reflecting on an element INSIDE the lens, either out onto the leaves, or back into the sensor; very rare phenomenon!

It’s not an internal reflection. It has a consistent position relative to objects in the scene, including the leaves right “under” it.
