All of us saw beautiful photos where the object is perfectly concentrated while the background is soiled. Such photo can be very drama and, could seem, would be to shoot difficultly. In this article we will give you some helps how to shoot at indistinct minor photos which will make impression and a family upon your friends. You also will understand that Depth of Area and how to operate it. Depth of area (also known as DOF for short) is the most important thing to understand before to shoot at an indistinct minor photo. Depth of area is defined as a range in which the photo is in the centre. For example infinite depth of field means, that a photo will be in the centre from certain distance from the chamber and indefinitely. Taking an indistinct photo the purpose consists in establishing depth of area only round object. Thus the object is in the centre, while a background behind it not. How you operate depth of area? Eventually there is no “a depth field” the menu in the chamber (there would be to be no that good …). Depth of area - optical number which is under the influence of several factors:
Distance of object from the chamber: It is obvious for understanding when it is taken excessively. Shooting at object of 10 foots from the chamber will lead to smaller depth of area than shooting in object of 100 foots from the chamber. Obviously strelenie in object which in all practical purpose is infinite distance from the chamber, will lead to the chamber, has concentrated on infinity and depth of the area which is infinite also.
The aperture: more widely the aperture (f number reduction) smaller depth of area and on the contrary: narrower the aperture (f number increases) bolshee depth of area. Only remember that depth of field changes along with f number: when f increases in number and depth of field increases and on the contrary. Unfortunately you cannot change only the aperture as you wish. Change of results of the aperture in requirement to change speed of a shutter (or manually or the chamber can make most possibly it for you automatically). More widely the aperture easier which gets through a lens and faster speed of a shutter, should be thus eat a limit to how wide you can establish the aperture of century
The central length of a lens: more shortly the central length bolshee depth of area and on the contrary longer the central length smaller depth of area. For example, if you use normal lenses somewhere in approximately 50 mm your depth of area will be much more than if you use scaling lenses in 200 mm. With long central length depth of area can be extremely small. For this reason of a lens of scaling - the good choice to shoot at a good indistinct photo which is actually concentrated only to object.
After understanding of the theory it is better to go to area experiment.
You receive sense of how your photo will be similar and as the indistinct background after will play with various lenses, various apertures and various distances from your object. If you posess the beginning of lenses of scaling with a capture of photos concerning close object, using your lenses of scaling. You learn, that it is extremely easy to receive an indistinct minor photo, using this method even, not establishing the aperture. As soon as you feel convenient with that installation, start to change the aperture and also change on your normal 18mm-55mm or similar lenses.
The majority of chambers allows to change manually the aperture, placing the chamber in “A” a way – while you change the aperture, the chamber will automatically establish speed of a shutter accordingly. Some chambers allow you to establish manually both the aperture and speed of a shutter. In the conclusion shooting at drama indistinct minor photos, it is easy with a small amount of the minimum understanding of depth of area and some eksperimentirovanija. |
