Today, digital enthusiasts want to convert analog to digital. There are many photographers, whether they have a digital camera or a traditional camera. They have more or less film in their hands. In addition to the expensive investment in film scanning, what else is there? The film is remake, right, with a digital camera to remake, but the price of buying the original remake is also very expensive, then how to use the cheapest way to achieve the digitalization of the film? The author will give you a concrete answer.
Need to know before remake
Light source: Usually, people are used to placing positive films under the sun or under fluorescent lights. The color temperature of daylight is 5200K, and the color temperature of ordinary fluorescent lamps is 4000K. Therefore, we choose the light source of about 5000K.
Macro of digital camera: Generally, digital cameras have macro, but there is only one manufacturer on the market - NIKON has its own special film remake clip, and NIKON CP990, CP995 and other machines have 2mm macro function, so micro The closer the distance, the larger the image, the bigger the remake pixel!
Digital file size selection: Generally choose the maximum pixel of the digital camera, the minimum compression ratio of the JPEG format, if you have special needs, you can choose RAW or TIFF format.
The most lazy display remake
Adjust the background of the monitor to white, adjust the brightness to the maximum, and then align the film against the monitor. This method is actually used for ordinary viewing of negatives, but if you really want to remake, you can't do it. You know that the display is a bit of a distance, composed of three colors, so it is obvious that you can see the vertical display lines after remake. Therefore, this method is not recommended for everyone to use, it can only be used as the simplest viewing film.
Light source: select computer monitor white background
Features: the most lazy, the most money-saving, the worst effect
The most economical energy-saving lamp remake method
First come to the hardware or lighting store to buy a 9W ordinary energy-saving lamps, and a screw socket, the price is 8 yuan and 2 yuan, so it is very convenient to get the material within 10 yuan. Energy-saving lamps do not need to buy high power, otherwise the heat is generated more, there is not much difference between domestic and imported.
Now we are making a simple light source. There is a protective cardboard outside the energy-saving lamps we bought. We will make a fuss here. First cut a larger than 135 film on the protective cardboard outside the energy-saving lamp. About 28x40 (135 film size is 24x36), then find an 80g copy of white paper to seal the mouth, in order to light, here you can choose other media to achieve better results, and then use non-reflective tape It is fixed on the opening and you're done.
Then you can energize the energy-saving lamp and place the film in the light. Then take a tripod to shoot. Take a negative and a positive film each. If you choose light-transparent paper, the effect is average, but it is slightly better than using the monitor directly.
Light source: ordinary energy-saving lamp, color temperature 4000K
Features: easy to make, easy to purchase materials, cheap
Best viewer remake
Every traditional film photography enthusiast has more or less a positive film viewer, both large and small. If not, you can go to the market to buy a common domestic viewer. The author has a viewer that can accommodate 4 negatives at the same time. The price is 160 yuan. It uses 6 7 batteries (AAA battery), and the external power supply is DC9V, 850mA. You can refer to it when you buy it.
It's a lot easier to have a positive film viewer remake, just put the film on it and shoot it.
This method is convenient and the effect is good. Because the author uses the camera macro, the effect is general. It is recommended that you can increase the close-up lens to achieve better magnification when you are shooting.
Light source: viewer light source, color temperature 5000K
Features: Using positive film viewer, accurate color reproduction
In fact, remake is just a simple film digitalization. If you want to achieve better results, it is recommended to use negative film scanning, but the cost will be quite large. There are many ways to achieve remake, this is up to you to DIY to achieve more, I hope that one day can exceed the film scanning effect!
Note in remake
1. In the energy-saving lamp remake method, since the temperature of the light source is high, the film will be hot after 10 minutes of shooting, so it is necessary to rest properly so as not to make the film roll up. In the current film remake method, the light source is a cold light source, and it will not be heated for a long time, which is very convenient and safe.
2. When shooting, the metering mode should be selected as the center-weighted metering, the exposure compensation should be reduced by 0.3 to 0.7 EV, and the exposure compensation can be reduced by 1.3 to 1.7 EV when reticle negative.
3. Set the white balance of the camera, depending on the specific camera, you can get results by trying several times.
4. Be careful when using the energy-saving lamp remake method to avoid electric shock.
