UV filter- with and without
Feb 7, 2018 10:54:48 #
2 days ago I posted picture #1 and asked for advice as to what is causing the horrible glare from the green lighting. Someone mentioned that it could be a UV filter which I have on my camera, strictly for protective reasons. I went back the next night without the filter and what a difference? So now I'm thinking about the effect the UV filter has had on the thousands of pictures I have taken over the years. Do you think a UV filter can degrade ALL photos, or just certain shots, such as this setting (bright lights in the dark)? BTW, I believe the settings are the same on both shots.

Before digital, filters were used extensively for color correction and other purposes but with the ability to correct white balance (at time of exposure and pp) those needs have mostly gone away. The only filter I use is a circular polarizer when needed and I buy only the best optical glass with state of the art multicasting (B+W, Zeiss, etc.). It makes no sense to spend thousands on a great lens and then throw a $37.00 distorting hunk of glass in front of it. I do understand the desire to protect gear but usually the lens hood and cap are sufficient.

Is UV filter is a light modification filter with a very specific purpose and that purpose is rediculously misunderstood by most posters on this forum as evidenced by their posts themselves.
If you need "protection" the by all means buy a truly CLEAR protective filter, all the manufacturers make them. ANY filter will offer lens protection, but users need to be FULLY AWARE of the consequences of using any light modifying filter for such a purpose. As you have found out yourself here.

Mike, Glad I could suggest a solution and it worked for you. I use a UV filter only when I need to protect the front element during hostile weather like sand, dust and moisture. It does help in natural light landscapes. If I am doing night photography the UV filter is OFF.

I'm a very big proponent of using UV filters, especially for protecting the front element of the lens. Obviously, it's the most exposed of the elements of the lens. However, there are times when using a UV filter can have some detrimental effects on an image, such as you've shown here.
Much like elements of the lens, filters are part of that lens assembly. Rely on only good quality filters. My K2, 25A, X1, polarizers, and UV filters are all B+W. I was sold on that manufacturer after a discussion with one of their optical engineers. BTW, that engineering discussion was an advisory to NOT purchase one of their products.
So, it boils down to carefully selecting which configuration you are going to use depending on the scene, circumstances, lighting, etc.

You must mean the glow around the type on the sign? The green glow on the ground is a good thing I would think, on the actual sign not a good thing.

Over the years, I have used good and bad UV filters. At this point, I only use Breakthrough Photography filters because of the extreme high quality of construction/design. Their coatings specifically prevent the type of reflections you are seeing in the "with filter" photograph.

Not a quality UV filter.

My father would at times work on the lighting on this bridge. Yes, the filter is a contributor to the green glare at night.
