Prevent trembling is afterwards after resembling element, big screen high, the manufacturer begins the 3rd kind when exert oneself publicizes to sell a site. Because respective technique is different, divide into camera lens optics to prevent again tremble, airframe CCD is prevented tremble, tall ISO is prevented tremble, the electron is prevented shake a few genre. Among them camera lens is prevented shake the mature skill that attributes a few old brands to turn over sheet camera lens to transplant DC, can saying is current the most mature prevent shake a technology, and CCD is prevented trembling is according to the number camera is designed, through CCD compensation of little scope displacement shakes brought smooth way to change, compensate reach the same goal by different routes with shot set actually, just one corrects smooth journey change, one goes catering to smooth road to be changed. The electron is prevented trembling is simple number optimizes a technology, be used by DV more did not say. And tall ISO is prevented tremble to have controversy extremely, say a kind rigorously to it is nevertheless " equivalent is prevented tremble " , did not correct make an issue of to smooth road, pass the promotion of speed however, your DC obtains higher rate shutter below same environment, will reduce the effect of hand shake. CCD is prevented shake principle sketch map 　 says impolitely once extremely red temporarily tall ISO is prevented tremble to just defend the firm that shakes a technology without optics, one when adopt remedies measure. Theoretic the camera that introduces identical CCD can be achieved same a highest ISO value, be like ISO1600, ISO3200, but past camera manufacturer is in the demarcate on ISO value 400 or 800, because taller ISO is worth, dot of overmuch a confusion of voices and splash had made the photograph becomes do not have the value of appreciation. Want to know precisian resembles cameraman, be in to a few brands occasionally the expression when ISO50 is dissatisfactory, think " grain sense is too strong, not quite exquisite " . ISO the value lifts, must powerful image handles ability to be guarantor card, ability falls effectively a confusion of voices arrives acceptable level. Technical development makes more and more manufacturers accomplished this, shake a technology to draw near to already physics is prevented for the product of the body, join " tall ISO is prevented tremble " it is to perfect nevertheless, but " double prevent tremble " appear force put forward tall ISO the earliest to prevent the brand that tremble to must return physics of research and development to prevent the old road that tremble to go up afresh, also be a kind of satirize. The manufacturer will be prevented shake a technology to be described all-purpose " clever medicine " , puzzled successfully a few consumer, think open is prevented after shaking a function, camera for love or money can take clear picture. But the optics with the most mature even if is prevented tremble, also can reduce the safe shutter of 3 archives nevertheless, below good position, promote 1/25~1/30 the second the shutter rate of 1/8s. It is more important that it is thus clear that he carry firm watch for a chance, when the light is too poor if not be,use horse, the speed of 1/30 second also can " burnt piece " . Shake a technology to preventing, we want rational look upon, both neither superstition is not repellent also, to its compensation value kind is added use, the picture that creates to tall ISO pledges the loss is known correctly. Need not too money of too clinging and floriferous injustice. Information source: Release a person: Chinese album net [examine a comment] (already had 0 comments)
