As a way that popular records and recreational entertainment. It is still a tenacious life today. Because of its simple photo method, and a variety of ways to play. So far, there is still a lot of lovers, and I have went to the SHAO research (Qian).
▶ The price of the film is always high, with an average of 3 to 4 yuan, the lace / special edition / limited edition may exceed 5 yuan. If the hand is often used, it is a rhythm of bankruptcy. So today we have explained in the most popular Fuji INSTAX.
▶ We look at the film from the film, in addition to the lace, Fuji Instax Mini film essentially only one specification, that is, the sensitivity is ISO 800. And do not distinguish between daylight / fluorescent / cloudy, etc. However, since the photosensitive area is different, this sensitivity cannot be equivalent to all kinds of digital cameras we usually use.
▶ Since the specifications of the phase paper are fixed. The mission of regulating the exposure is gloriously in the body. Due to the maximum amount of MINI 7S / 8, a fixed shutter speed is 1 / 60s. In the end, only the aperture can be adjusted. Take MINI 8 as an example. There are 4 regular apertures and 1 gear Hi-Key aperture to be adjusted. It is F12.7 (indoor) F16 (cloudy) F22 (cloudy) F32 (sunny), Hi-Key is a larger diameter than F12.7 (indoors). The specific F value is officially not given. 7S does not have an exposure indication similar to 8. Which type of aperture is specifically selected, you need to rely on experience, a little luck, and a lot of money. Therefore, in the case where the difference in 7S and 8 is not large, it is recommended to buy MINI8, multiple aperture optional, and have exposure prompts (although not very reliable).
▶ The full range of instax mini has used the exact same 2 groups (this is also too province) 60mm lens. It can speculate that there is no coating without any plating film by visual inspection. In addition to increasing the injection of light, do you have problems such as ghost, glare? We will talk below.
▶ All instax is equipped with a flash. Among them, Mini7S and 8 are forced flash, that is, pressing the shutter, will trigger flash. The remaining models are automatically decided to flash. Flash can act as a supplemental light source in some cases. But most of the time will make the picture uneven, and there is a case where the reflective or miserable. However, for some people, the flash played a whitening effect. Special attention: No matter what camera, you must ensure that the flash is closed when you use the camera, especially the baby. If you don’t work, you will rub it with your hand (for 7S / 8)!
▶ The theoretical knowledge is finished, we immediately entered the practice link.
▶ First we take (a) (b) (c) (d) four pat pats.
▶ Obviously, (a) (b) can see most of the two main body parts occupied by black and white.
▶ The situation of (a) is referred to as exposure. There are usually two reasons why this problem: (1) The environmental brightness is too large, exceeding the scope of the pat. (2) In addition, this will happen when the aperture is adjusted correctly. Especially MINI 8, the power is default “indoor” mode.
▶ For (b), it is called insufficient exposure. In addition to the case where the aperture is not set correctly in the above (2). A larger possibility is that the brightness is too low, exceeding the range of adjustment. Because the ISO that is taken is only 800, and the aperture is only F12.7. Therefore, special methods are required for the case where the light is particularly weak.
▶ (c) (d) Two photos, the environmental brightness is moderate, and the exposure is reasonable. So the picture is clearer. However, because the dynamic range of the filming is extremely limited. Even under the ideal conditions, it is difficult to ensure that all scenes are clear and bright. So don’t have to be too strong when taking pictures, the main body is bright.
▶ These two groups are taken outdoors. Please pay attention to the position of the arrow. We see in the theoretical part. The lens of the Instax is no coated. But when they encounter strong light. It doesn’t show glare or ghost. Instead, it is directly in light! It is believed to be formed because the excessive light is formed in a strong reaction of the photosensitive substance. The previous photo is due to the direct sun of the sun. The latter photo is a highlight of the flashes that are filled with a flash to reflect on the glass caused the black spot.
Example of three
▶ The last set of photos of these two photos is obvious, and the main body of the picture is too bright. This is because the error uses the flash caused a large area of reflective.
▶ There are many environments in reality, and only a few most typical scenes can be explained here.
Sunny day + outdoor
In the cloudless outdoor, due to the fierce sun, the metering system plus the measurement system is simpler (or simple). Photography objects are farther than people (such as systemic images, half-length or big heads. It is likely that the background is clear and the people are gray, and the flash is not obvious. In order to ensure the clearness of the main body, it can be adjusted to the angle of the sunlight, and the environmental brightness can be reduced on the one hand, and the other aspect can prevent the sunlight to generate an annoying black spot. For two manual models of 7S / 8, you can switch to the cloudy mode. For 25/50/90/210 and other automatic models. Then you can press the L-key to perform exposure compensation. Such a portrait will become more bright.
In the scenery photography without portraits, there will be excessive exposure. In addition to selecting a sunny day mode (manual model) and use the D key (automatic model) to perform exposure compensation. You can also try to use a mirror or a polarizer. Before placing the corresponding filter in the lens, you can play a good dimming effect. Since the picture quality is not high, the filter does not need too high, and there is a small diameter of a small diameter of about 20 yuan.
Next night / night + outdoor
It is a very big weak term. Because the film sensitivity is not high (ISO 800), and the aperture is not large. Therefore, it is very careful when choosing the night scene. Landscape such as sunset, sunset. Unless MINI 90 can be manually exposed, and the remaining machine type does not recommend an attempt before the tripod is fixed. Otherwise, it is prone to appearing a darkness like it (b) above. If it is a night image. The characters should be made to the camera (but not less than 60 cm focus distance. Unless you use a near-mirror) and the flash is used. If it is still not lit, Mini 8 can use Hi-KEY mode. 25/50/90/210 Lamp type can be highlighted using the L button.
Night + interior
Interior photography at night is a considerable challenge for pat photography. Because the human eye has strong adaptability to the environment where the light is insufficient. Many times we feel that the environment is very bright. In fact, it is difficult to exposure for the camera. So when we feel a bit slightly in the indoor feeling. It should be noted. Mini 7S’s aperture gear is less, it may be more powerless. However, it is generally possible to use the flash. Note that an object that avoids reflective light can be avoided. MINI 8 can use Hi-Key mode. The remaining models are not too big in this environment.
Special attention often uses the flash to fill the light in the condition of insufficient light. The flash is very sensitive to glossy objects. For example, glass, metal, lacquered wooden board, glossy plastic, etc. extremely easy to cause reflective, which will cause a photo of the photo. You can stay away from these items when you take pictures. The environment is bright, you can turn off or cover the flash. It is really necessary to use the flash, and it is impossible to avoid reflective items, you can try to take a piece of paper towel, peeled a layer, and the cover acts as a soft mask on the flash. Converts the light source of the flash to a relatively gentle source.
