The expression mm1332 precision was only known from the reference materials, but the exact content was not clear. It may be a precision technology or concept related to a certain machine tool (such as the mm1332 machine tool mentioned in Material 3). At present, a more detailed and accurate explanation could not be given. "Qiao Yun" is also a wonderful novel. Everyone is welcome to click and read it!

The camera's precision parameters referred to the size of the actual object in one pel, expressed as (um*um)/pel. The size of a picture element was not equal to the precision. The size of a picture element was fixed during the mechanical construction of the camera, while the precision was related to the field of view of the camera and was variable. The smaller the precision value, the higher the precision. The size corresponding to a single pel = width of field of view/width resolution = height of field of view/height resolution; the pel accuracy = pel size/lens magnification; the pel accuracy = camera field of view/camera resolution; the simple evaluation method of the detection accuracy is: Detection accuracy = the actual size of the X-axis of the image/the number of X-axis pixels. However, the final detection accuracy will be affected by many factors, including the moving speed of the object being measured, light interference, the shape of the object, the contrast of the features, the computing power of the software, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many ways to control the background of a macro camera: - ** Use artificial background **: You can use colored or black cardboard. Black cardboard is more commonly used. If you want to shoot a more natural effect, you can choose pure green or mottled green cardboard, but avoid using reflective cardboard to avoid impact on the subject. - ** Illuminate the main body with a flash **: Use the flash as the main light source to illuminate the main body and blur the background. If the background was a solid color, the position of the flash was not critical. If a hand-drawn mottled background was used, it needed to be placed outside the focus of the camera to make the mottled pattern on the cardboard look softer and blurry. - ** Control the light with the flash **: Since the flash can completely control the light, the output power of each flash can be adjusted individually. If you want to highlight it on one side of the main body, you can increase the power of the flash on that side to freely set the light ratio. Use a flash on the right and left side of the main body. When the power is the same, the surrounding light effect can be shot. Increase the power of a flash and combine it with the aperture value to shoot the effect of a stronger light source in the left and right directions. - ** Control the background with a flash **: Add a third small flash close to the cardboard behind the subject. By moving the flash close to the cardboard, the background can be brightened or darkened. The same effect can also be achieved by turning on or off the power. In some cases, dimming the content behind the subject can make the subject more prominent. - ** Create a black background **: First, use a black cardboard; second, use two flashes. When the two flashes are turned on and the aperture of the camera is Ü/ 16 or Ü/ 22, even if there is a green cardboard behind the subject, it will turn black (the result of light decay). This technique can be used to shoot a black background in the wild at noon on a sunny day. With an aperture of Ü/ 8 or Ü/ 11, sunlight was enough to illuminate the background; if the aperture was completely reduced and the high-speed flash sync reached a shutter speed of 1/1,000 seconds, the background would be completely black. Sometimes using a black background can make the main body stand out. If there is a lack of separation between the flowers or if the flowers merge with the black background, you can use the third flash to backlight the main body, creating a halo or edge light to increase the drama. - ** Cloudy Day **: When shooting on a cloudy day, the background is dark. If you want to capture details, you can lower the shutter speed to let the surrounding light enter the camera sensor. Try to use slower and slower shutter speeds until you achieve the desired effect. In this case, you need to use a tripod, especially when the shutter speed is reduced to 1/30 of a second. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
