The photos are all dated 2014, three or more years ago. You’re just getting around to asking this question now? I see you are a relatively new member, but it seems logical that you would have contacted the camera manufacturer, the camera retailer, the edit software manufacturer, the sd card manufacturer, etc., to get an answer back then. Were you using a flash? If yes, what speed were you synced for? Not trying to be a wiseguy, just applying a little logic.


Meta data shows this. This is most certainly a reflection of some type.

It's so weird because it reads to me so much like a net, physically between you and the subjects. good luck figuring it out!

The point is that, whatever the cause of the gridlines may be, there is a distinct pincishioning effect on the gridlines.
Just an observation without, as yet , a reasonable explanation.
Pincushioning is often assumed to be strictly an optical deformation phenomenon. However, that it can be digitally minimized ...or increased, indicates that it is not exclusively an optical phenomenon.

You can also correct keystone and leveling and a host of other optical "aberrations".

Pincushion, barrel and mustache distortion are strictly optical distortions that have nothing to do with what is happening in this case. They are commonly associated with zoom lenses at their extreme ranges although a few primes (like fish-eye lessens) also exhibit them.

It does, that is why I think it is something being reflected onto the filter. The plexiglass has probably picked up a reflection of the net and passed it onto the filter. The distortion being changed as the angle of the lens/filter changes.

IMHO, Szalajj is totally correct when he says to get rid of the UV filter and here's why.

This is likely an image coming from outside the FOV of the lens. I found this a fairly common effect when regularly using a UV filter in the old film days. With anti-reflective coatings being more common today, it's less of a problem but still there.

What happens is a strong image enters the UV filter at an oblique angle just outside the FOV of the lens. Light rays that strike the filter at nearly 90 degrees from the lens axis simply reflect off the filter surface (total internal reflection) and are not a problem. The light is bent by the filter and reflect (multiple times) between the two pieces of glass, separated by air, and some of those reflections end up in the FOV of the lens. The basic principle of internal reflection is what makes fiber optics work.

I have attached an example image. In the past, I've experienced this effect too often when using UV filters, but this image was a catastrophic failure for me. It was also the last time I used a UV filter while taking a picture. It was also the last time (1975) that I experienced this problem.
Thank you.

I ditched the UV filter for lens protection because, for me, the whole reason for carrying a camera around was to capture an image in time that represented an irreplacable memory or experience of mine. For me, that was and still is more important for me that the risk of damaging my lens.

The following image is an example of reflections entering the image outside the FOV of the lens, which, I believe, is similar to what the OP experienced. The reflected images that ended up in the picture were actually just outside the FOV of my camera.

Again, just another thought to consider. Hope this helps

I've experienced a phenomenon when shooting the moon with a clear filter on the camera. The moon appears as an observe green reflection on the exposure, because it reflects off the lens onto the filter, where the sensor captures it as part of the shot.

This grid pattern could be a reflection off of the mesh covers on the lights above the rink.

The only way to confirm my suspicion is to go back to this same rink, and shoot another game without the filter on the camera.

Is there a net hanging above the glass anywhere in your camera's line of sight? This could have caused the grid pattern reflection in the second shot. The reflection is bouncing off the lens back onto the filter, and being captured by your sensor.

Ditch the filter and try. Extra layer of glass to have reflections. And some lenses do not play well with filters at all.
As to the date in the exif data, you can reset the clock and change the dates for the copyright info etc. , but on my metadata app the date comes up 2017 so where do people see 2014?

enlarged the image looks just like a woven net or screen, you had a filter, was there a net or screen nearby to reflect or are the lights covered with a mesh that might reflect off the filter?

The fact remains that observation of the distortion of the “grid lines” in question, over the side of the head of the person (which is not distorted) reveals quite clearly a “pincushion” deformation. That fact is indisputable; the explanation is yet to be explained.
The point I made was that, although distortions of several sorts can be imposed on a captured image optically during its capture, we all know that correction (or exacerbation) of the deformation can be digitally controlled after the fact. Hence, there can be more than one cause of such deformations. The phenomena involved in thepresence of the grid lines in question, and the cause of distortions thereof, have yet to be determined.

My handle is Brooklyn-Camera 2014...... Second these pics were from 11-11-17. I have shot both at the bench and through the glass and never had results like this. I guess that some of the people on this blog never reads any posts and jump to the incorrect conclusion. I don't need to keep my RAW files and save for prosperity, I post the photos and that's it. I am not asking you to do anything for me, just asked about these photos.
Seems as if no one can answer or ever had the same results as I have. By the way I have shot a ton of hockey games for your information and see you have no input of any use. Thank you.....Brooklyn-Camera 2014.

The presence and absence of glass explains everything.

Unless that was the only hockey game where you ever took photographs or if you always sat in the player's box at every game, I'm not convinced that your memory about the glass in this case is accurate.

It's really up to you to repeat the test and see if you can get the same results. We can't do that for you.

The fact that you did not notice the problem before you discarded your raw file three years ago does not help.

RAW files take up so much room on the HD. I have an external HD and I would need a truck load for all the photos of hockey and football games that I shoot for.


I don't erase my SD card. They are cheap enough I use them as an archive encase anything happens to my hard drive.

Shooting with the same camera 7D MKII and a Canon 70-200mm f/2.8 lens these photos were taken at the same game. Shooting info ISO 6400 70mm & 200mm, f/3.5, 1/800sec. Seems as if it is present when I first start shooting, could it be the cold effecting the camera from when I first start shooting? Don't have the RAW anymore, I dump them after I post the photos. I am not shooting through the glass, shooting from the bench.

Any and all help will be appreciated and thanking all members in advance for your time, effort and knowledge.

I have seen this before with a 35mm lens in cold weather. It cleared after a very few frames. I think you are looking a temp issue. You have experience in the rink and my guess is the cold coming off the ice affected your lens/camera combination. The high ISO may have added to the problem but sounds like a need. The RAW files might have helped but I really don't think would have added anything. I would suggest trying to create the issue again on purpose to see what is going on the arena and taking careful observations of surroundings. That may not be possible but may really be the only way to know.

It appears to me all the photos were shot from the very same point, through the players bench. Viewing the photos it seems the "lines" are projected onto the lens from above or from the side of the bench. I have two lights in my basement that have metal, and glass covers that will project this type of pattern on the outer protective cover. Hope this helps.

So you and the players sit on an unprotected bench during the game? If that is correct, I certainly would not be sitting there and take a chance on getting hit by a puck. Or my lens getting hit.


Have you ever watched a hockey game?? The player's bench is unprotected. That is how they get on and off the ice.

I guess you did not read my next post before responding.

In your original post you asked, "... could it be the cold effecting the camera from when I first start shooting?" You got lots of information about what might have happened, some of it off base but some was not. I ended up by pretty much agreeing that your first guess was right and I explained why.

If you feel that what I (and others) suggested was not "of any use" then maybe next time you should ask your questions elsewhere.

What you state as fact is really your opinion which of course you are entitled to. In your statement, you acknowledge that the head of the person in not distorted. Well it should be unless you are suggesting this is a composite of two images: one with pincushion and the other without. You can’t have it both ways.

If you want answers, UglyHedgeHog forums are absolutely the place to be. You'll get them by the truck load.

If however you want meaningful/useful/reasonable answers, well, ..., not so much. Those are pretty rare.

[ The flip side is that most of the questions are just as bad. ]
