I visited a few Southeast Asian countries last week for business, including some I had never been to before. It seemed like most of those countries didn’t have clear regulations on windshield tinting films. Of course, that might be because they are hot countries. Most vehicles had quite dark tinting films applied to the front windshield as well as the side and rear windows. During my visit, I conducted sample installation work on a few vehicles. While I initially explained the benefits of the CPL filter and recommended installing it since it comes as a standard component of Vueroid S1 4K, I ended up advising against using the CPL filter after inspecting the footage from the test drive. CPL filters indeed reduce light reflection, but it is also true that they lower sensitivity significantly.
As
@lufa6977 mentioned, it is expected to greatly reduce the advantages of a telephoto camera during night driving. If capturing license plates is truly the primary purpose of a telephoto camera, I also still believe a CPL filter is not appropriate.
However, what
@TonyM mentioned was something I learned for the first time. I wasn't aware of the fact that it allows you to see inside other target vehicles better. That’s very interesting. Should I understand this as the CPL filter on the camera installed in my own vehicle, reducing the glass reflection of the opposing/target vehicle?
@Chuck McCoy Yes, it's James
🙂 . It looks like I should definitely bring some Soju to this year's SEMA... (or not
😉)
I don't think the shared video is a fair comparison. A video shot in a shaded area and a video shot completely outdoors are bound to show different results. Also, looking at the top video when the vehicle enters the outside, sunlight is shining obliquely from the front right. You can see the sunlight hitting the passenger's face. This indicates that light is entering the interior. Even looking at the dashboard, a certain amount of light is entering due to the sunlight. However, the interior remains dark.
In the bottom video, there are no shadows around the vehicle at all. The sunlight is coming down almost at a right angle, so only the driver's hands are receiving sunlight. Even if sunlight reflects, it is an environment where it is difficult to illuminate the interior.
I also suspect whether the two compared vehicles have front tinting applied or not. At the end of the bottom video, there is a side view of a vehicle turning left in front of the McDonald's sign. It has no tinting at all, so the rear of the vehicle is clearly visible through both side windows. Even though it is the same location and exposed to the same sunlight environment, the interior visibility of the subject vehicle and the left-turning vehicle looks completely different at different distances. I have my doubts about whether the bottom vehicle is tinted.
Still, the point about being able to see inside opposing vehicles better remains interesting. I just checked various aspects through AI, and it explains that it really is effective to see through the window shield of the other vehicles.
It's not that I'm trying to avoid applying CPL filters. Currently, offering CPL as an option using a common design wouldn't be difficult. However, due to my personality, I just don't like releasing something to the market merely to fill a lineup when I haven't convinced myself yet.
