Fool machine many young people now do not know the term "fool machine". The original cameras in the digital age are called "card machines", which are now highly hyped CCD cameras. And fool machine, now more called portable film machine, or compact film machine.
The definition and scope of a stupid machine is very vague. in general, it refers to a compact camera that can just press the shutter. There is no need for other operations, no need to control exposure, no need to focus, just press the shutter. Most stupid machines are made of cheap plastic and stuffed with two simple circuit boards with low cost and high output.
TC-1,T3,GR1, which was very popular a few years ago, all belong to stupid machines, but they are the king of stupid machines and the most advanced stupid machines.
In fact, the most typical fool machine should be a disposable camera.
The so-called automatic exposure and autofocus of the fool machine looks like a very advanced technology, but it can be done in an opportunistic way, not automatic exposure, but fixed exposure, not autofocus, but no need for focus.
Moreover, the two must be linked.
There is no need for focus, which means that the lens has such a large range of depth of field that it hardly needs to focus. Take the above disposable camera as an example, its lens focal length is 32mm, the aperture is fixed F10, this camera as long as 1 meter away, all within the depth of field, so that only need to prompt the user to use about 1 meter away, there is no need to focus.
But the focus problem is solved, your aperture is only F10, how to solve the exposure problem? Since it is a disposable camera, it certainly will not set up a complex shutter module, and the shutter speed is fixed at the position of 1x140. Then we need a flash. The disposable flash function is certainly not as strong as it is, so it can only flash for 3 meters, but not at a distance of 3 meters.
In this way, a set of fixed system is completed, and what the user really needs to control is the distance, don't get too close, you can solve all kinds of problems. As for the speed of 140, can the F10 be universal during the day? What if the exposure is not allowed? What can I do? cold salad!
Fuji even has the coquettish operation of comparing disposable cameras with mobile phones, which is too fierce.
Some friends may say that this method of shooting has not been used before. It is true that this method can also be used on cameras like the Lulai 35, but the Lulai 35 does not have a flash, and the stupid machine actually relies most on the flash.
We should not think that the concept of this stupid machine is far away from us. Fuji Polaroid is the most typical successor of this photography method. The operation logic of the entry-level Polaroid camera is exactly the same as that of the disposable camera.
But this does not mean that the stupid machine does not have a level, it is all such a stupid operation. Indeed, some stupid machines operate in the same way as disposable cameras, so they don't cost much. It was also common for some basic fool machines to use plastic lenses directly, so in those days, some card machines sold for as little as 5000 yen, only the 1max 10 of an advanced portable camera and the 1max 5 of a more fully functional portable camera.
Starting with a pure fool, there are three places where you can evolve.
First, the lens gradually changes from a fixed-focus lens to a zoom lens to adapt to more environments. Before 1998, the fool machine is mainly the fixed focus world, but after 1998, the fool machine basically uses the zoom primarily, the optical zoom 2 times, 3 times is the mainstream, later also has 4 times. Among them, the wide-angle end is the most common 38mm, while the other end can reach 170mm according to different magnification, while 130mm and 150mm are more common.
(this is a 38mm-170mm zoom fool machine) 2, autofocus, some non-top idiots are also equipped with autofocus, their focus basically stays at the level of linkage distance measurement. With these fuselages, with the technology at that time, there was no way to do the kind of auto-focus on the SLR. But it also means that these stupid machines can focus and manipulate the depth of field. Its basic principle is that the fuselage measures the distance from the object by infrared and so on, and then adjusts the focus position to the corresponding distance. For example, if the gear is 2.8 meters, then the gear is 2 meters, 3 meters, and 5 meters, then jump to the focus gear of 3 meters, and the lens moves to the corresponding position to focus.
This kind of autofocus depends on the number of gears, such as Fuji's GA645 series, which has a large number of gears and is often right and wrong. Generally, it is not a top-level idiot machine, and the distance gear of auto-focus is not much.
3, the exposure function, that is, the shutter has a gear. Generally speaking, the shutter of a stupid machine is not too fast, even for advanced portable cameras, but in our daily use, we do not use a shutter of more than 125.
Fool machine is good at fool operation. Interestingly, if you add manual functions to it, such as A gear that can be controlled, the function that can control the focus distance, etc., it will become a professional fool machine instead.
Some people think that the stupid machine refers to the kind of rough and simple plastic camera, such as the T3GR1 can not be considered a fool machine. This is true and wrong.
The reason is right, because these professional cameras are indeed much more advanced than stupid machines, most of them have a certain manual ability, and basically equipped with high-performance lenses, many of them are aspheric lenses.
This is not true because the focusing logic and exposure logic of these advanced portable cameras are indeed the logic of stupid machines, so in principle, these advanced cameras also use large depth of field to focus, because they also have a large lens angle. Moreover, the most advanced portable cameras can not fully achieve manual functions, especially the focus is basically focused by distance, but divided into more details.
In other words, if you use a fool machine to take advanced photos, it actually requires some professional skills. If you use it wayward, there must be a large number of waste films, and the distance of the machine will be difficult to grasp.
Fool machine can be called the product of the times, its active period is only about 10 years, but it is the most important product of the popularity of photography. Not all families have a need for professional cameras, and a stupid machine is enough for daily records.
According to our current technology, it is not a difficult problem to make a fool machine with high speed and high accurate focus, but no manufacturer wants to take a risk on the film camera. after all, digital elimination of film is a deep-rooted idea for manufacturers.
So, is it possible to play a fool machine when playing with film? I think the DSLR is better for the novice. After all, the DSLR can not only take pictures, but also teach you to take pictures. The effect created by a fool's machine is often caused by defects in plastic lenses or shoddy glass lenses, which are a little tasteful at first, but get greasy when you see too much. Therefore, the fool machine can play, really when the main camera can only sweep the street.
