Digital chambers support many photos shooting at ways - from automatic point and hunting to a management where the chamber does nothing for you. One of those ways - the Aperture Priority. The aperture priority is useful in many situations and deserves that short explanation, that it and how to use it. You establish a way of a priority of the Aperture at use of the menu of the chamber on its LIQUID CRYSTAL MONITOR when you should see and choose a priority of the Aperture from the menu or rotating disks of ways when you choose the Aperture priority its symbolical image (in most cases, the Aperture priority is symbolised by the capital). In a way of a priority of the Aperture you manually establish value of the aperture. The chamber cares of all the rest – for example she establishes optimum speed of a shutter for the aperture which you have chosen. There are physical restrictions and not each value of the aperture which you choose, can be picked up in other parametres of adjustment which will lead to a good photo.
The chamber will inform, highlighting CONDUCTED green colour, or some other way (check up its management on bolshee quantity of details) if it has found optimum parametres of adjustment which work with your chosen value of the aperture. So, why the anxiety establishing the aperture, estimates manually when you could establish the chamber it for you? One serious basis should operate depth of area. 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 is in the centre from certain distance from the chamber and indefinitely.
Narrow (also known as small) depth of area on the other hand means, that the photo is in the centre only from certain distance from the chamber to other distance which is not further away (or in other words the photo is in the centre only round certain object which is photographed). Other part of objects in a photo not in focus appears as the soiled objects. More widely value of the aperture (f number reduction) narrower smaller depth of area and on the contrary: narrower value of the aperture (f number increases) are deeper depth of area. Only remember that depth of field changes along with f number: when f the number increases depth of field increases and on the contrary.
Usual use manually to operate value of the aperture and to reach narrow depth of area, taking photos of a portrait and trying to soil a background behind object of a portrait. As always the best way to understand, that you can make with various parametres of adjustment of the aperture, consists in experimenting. Thus you receive feeling of that values of the aperture translate to what depth of area. It is important to understand, though it, depth of area depends not only on value of the aperture but also and from distance of object from chamber and lenses which are used. With the digital chamber eksperimentirovanie is free and immediate as there is no cost of development of a film, and you can consider the photos instantly. |
