Will paper contracts fade if they are often photographed with flash?

Paper contracts often use flashing lights, which will not affect her much, unless they are placed in a dark, damp, and unventilated environment, which will affect the paper contract.

Hello friend, I don't think this will be, it won't fade Well, in addition, it's better to save the electronic version of the contract, thank you.

Paper contracts, as long as you keep them carefully, or seal the edges, it will not fade easily, you can rest assured.

This general one will not fade, so if you want to make him look at his legs for a hundred and eighty years.

I don't think so, but I don't think anyone has a casual and elegant area, so I'm going to shine on him with a flash all the time.

I don't think I'm so squeamish.

Will paper contracts fade if they are often illuminated with flash? Paper contracts will fade if they are constantly flashed.

If the paper contract is often illuminated with a flash, it should also fade often, and this should still be something very idle, so this should not be able to directly carry out some of his flash tricks.

Until the contract, if I often use a flash light, will it fade? I don't think so, I haven't experienced lighting, it's lighting that doesn't have much to do with fading, right?

Long. Will the light fade from the mountain? Yes.

Paper contracts will gradually fade if they are constantly illuminated with flashing lights, because they will also react.

It's definitely going to fade, it's just slow. The flash color temperature is around 6500K, which is about the same as the daylight color temperature around 9 a.m. during the day, and shooting banknotes with the flash is the same as when exposed to sunlight.

The key to preventing the banknote from fading is to avoid exposing the banknote to the sun. Banknotes will fade to varying degrees after a long period of preservation, which is directly related to the quality of the paper and ink. Banknotes should not be cleaned with alkaline or acidic liquids, otherwise they will cause fading.

Once the banknotes have faded, they often cannot be repaired.

With the flash I think it's fine, the optical response of the banknote shouldn't be so immediate. Even if there is fading, it is not immediately recognizable to the naked eye, and how many times it will (obviously) fade will take you, I'm afraid you will have to spend a lot of batteries to experiment.

Yes. Over time, it's slow, but it's going to happen.

To be sure, if your money is a real banknote, it won't fade because of the flash. With or without flash, it will fade over time, but it won't be noticeable.

Flat paper like this is not large in size by scanning, and the flash shot will not affect the color of the banknote, which can be ignored, while the cultural relics are not, because some of the light will accelerate aging and fading.

I guess there are 80,000 times, if not 100,000.

Any printed matter on paper will fade under bright light.

If you think so much about the color of your legs, you can simply take it and wash it, and your legs will be faster!

The ** shot is never the original color, and will definitely change color according to the color temperature of the flash and the hue of the camera itself.

There is a flash to take pictures, which looks a little worse.

The range of use covered by the flash is also limited. For example, shooting things that are too far away will not help.

You can't rely on flash.

Frequent use will also cause a certain amount of wear and tear on it. It has a certain lifespan.

The picture came out because the camera was not stable, and then there was not enough time.

To take photos in low light, you must use a tripod and open the aperture wide for a long time**.

In terms of shooting quality, the flash is prone to cause large areas of reflection, and strong white light will cause color saturation to decrease, which is often referred to as not vivid.

From a physical point of view, the ordinary wavelength of visible light is between 400 nm and 700 nm, and the ultraviolet energy below 400 nm is very large, which is easily absorbed by objects, thus causing the object to deteriorate; Infrared rays higher than 700 nanometers have small energy and are not easily absorbed by objects, which is very safe. Wood, plants, silk and other substances are all polymer structures, containing cellulose or protein, which are easily affected by light, electricity, and bacteria and deteriorate and damage; Other substances such as stone, copper, iron, and ceramics are not easily affected by light. The flash models we use vary from long to short wavelengths.

However, it should be less than 700 nanometers of visible light, which is more or less damaging to the cultural relics with polymer structure. Therefore, it is forbidden to use flash photography for cultural relics such as wooden buildings, calligraphy and paintings, silk products, and wall paintings.

From the perspective of copyright, museums and art galleries own the copyright, and they are worried that you will take pictures for commercial use, so you are not allowed to take pictures, let alone flashes.

Recently, it has been confirmed by the test that whether the balloon will be flashed by the flash is also directly related to the distance, and whether the flash will cause damage to the human eye, which is really a matter of concern to everyone!

Experts say that it doesn't matter if you take a flash photo once or twice in a short time, but if you play for a long time or many times, it will damage the macula of the eye, "The macular area is the most sensitive place in the human eye, and it is also the most acute place for vision, if it is damaged, it will cause vision loss." ”

Experts said that flashing lights, bath bomb lights, welding lights, laser pointers, strong sunlight, etc. are all strong lights, and we should pay attention to avoid long-term contact between eyes and these strong lights in life. In addition, the ophthalmologist also reminded that many people like to play with their mobile phones before going to bed, and they must pay attention to adjusting the brightness of the mobile phone screen, and it is best to turn on the lights in the room to avoid excessive contrast sensitivity and damage to the photoreceptor cells of the human retina.

If the screen of the mobile phone is too bright, we will feel very clear when we look at the mobile phone, but after a long time, due to the excessive contrast sensitivity, it is easy to cause fatigue and blurred vision. Therefore, dimming the light of the screen appropriately, and then increasing the illumination of the surrounding environment, is relatively protective to the eyes.

It will not damage the lens, "a large piece of **" is actually too violent, that is, in some places it is white and can only see white, in this case it is caused by the flash line is too bright, even if those high-end cameras, the parameters are not right, and there will be too much violence when shooting.

What kind of machine are you using? Slr?

This kind of has no effect, but what infrared transmitted light you use to aim at the phone camera may have an effect.
