The most important indicator for judging the quality of the quality filter, especially the ND optical light mirror is whether it is colored under long -term exposure. For this indicator, the performance of many big -name manufacturers is actually unsatisfactory. France Gao Jian released the latest Nuances “Super Fine” series of light reduction mirrors, claiming that long exposure is never color, is it another gimmick?
Gao Jian is an old -fashioned optical filter manufacturer, but in other filter manufacturers’ “glass tide”, he has not released new products of his glass filter. Fortunately, “late is not better than better”, Gao Jian finally released its latest product line in the romantic Paris: Nuances “Super Fine” series ND light mirror.
The new series of light reduction mirrors have the highest light reduction capacity, and the most practical 100mm product line is currently available
ND2, ND4, ND8, ND32, ND256, ND1024 total 6 products
Why is there no gradient mirror? Well, Ao Jiao’s French said that there is only ND now, GND will come out later …
But they also said,
Now this series of products are quality, you know it.
(Smile with a heart)
So I got three products of 100mm specifications: ND8, ND256 and ND1024. Maybe you have doubts about the words of the French before, but when you disassemble the packaging, you will rest assured.
Because holding the filter in your hand will have a heavy feeling, unlike other brands I tried before,
Gao Jian’s ultra -fine fine filter is slightly thicker
Essence Gao Jian claims that it uses “High temperature, high strength, high hardness, high light transmission rate, low reflection and chemical stability manufacturing.” (Translation: It means NB)
And when you put the three filters together, you will find them
The appearance is dark, indicating that the reflectance is low
Essence At this point, Gao Jian announced that its “developed nano -coating process double -sided coating, uniform coloring, high light light and low reflection, establishing accurate neutral ash, avoiding interference from infrared, ensuring the overlapping use of multiple filters to use There will be no colored phenomenon in it. “(Translation: Still meaning NB)
So is this new filter really as high as Gao Jian, the quality is so good? Let’s take a look at what the filter that is not so good looks like.
1. The problem of passers -by nail filter
For glass filters, there are two main aspects that affect the picture quality:
Reflection and partial color
Because there is no anti -glare before the filter is installed after the filter is installed. If the reflectance of this filter is relatively high, the shadow of the camera will be released in the bracket, and this will become like this.
The reflection of the filter is presented on the photo
This problem is generally eliminated by covering a black cloth on the lens. However, the lens may be blocked during use, so it is not convenient.
Another problem is relatively sad. This is determined by the imaging characteristics of the digital camera, and the long exposure will be colored. On this issue, glass filter performance is significantly better than resin, but it is also unsatisfactory. A better glass filter, under the exposure of about 30s, will produce a strange color of blue or reddish red, such as this.
Trivial caused by long exposure
If the problem is not serious, it can be restored through PS and other later corrections, but it is more troublesome to operate.
2. The performance of the high backbone filter
So what is Gao Jian’s filter?
Xiaobian dare to show you the raw original format of the shooting:
In the case of just adjusting the exposure (the long exposure of the sun will be darker),
Regardless of whether it is exposed 20s, or multiple exposure 59s, there is indeed no obvious coloring phenomenon. And there is no obvious overwhelming light in the case of backlight.
After the later adjustment, a set of good photos was born. (Don’t ask how Xiaobian is adjusted)
20s; F7.1; ISO200
59s; F6.3; ISO200
If you care about whether such a thick filter affects the picture quality, Xiaobian releases the center and edge screenshot of a photo for you.
30s; F9; ISO100
It can be seen that the details of the bridge are still very clear when the 100%magnification.
So the French full of romantic feelings did have a technical control this time, bringing us a strong light reduction mirror. If you have to be fascinating, it is that the thickness of this series is indeed more thick than other brands, and it is a bit crowded in the original bracket. But in fact, this is not the point, the point is:
Gao Jian should not be proud anymore, let out the gradient GND together!
Love photography, happy to take pictures. Photographers who do not love equipment are not good editors. This is the Getty Images signing photographer, because I love to come here. My photo has boarded the National Geographic. Ask the questions about photography skills or equipment. Because the technical techniques on the NG homepage will not be too bad.
