You possibly took photos before only to learn later, that they did not leave predictably. Though digital chambers begin cleverer there are still many decisions which the photographer should accept. There are also many errors which the photographer can make. Here seven general.
Many errors can destroy a photo. Here the list of seven general. The first step which will avoid them, should understand that they and why they destroy a photo. The second step should know about them, shooting in your photos.
Not in focus: not in focus the photo looks indistinct and has low contrast. Usually such photo is useless and cannot be corrected. The majority of digital chambers can automatically establish the centre for you, and in most cases they choose the correct centre for a scene. Some scenes however it is heavier to concentrate and can make a fool camera’s avto of the centre mechanism. If you use chamber SLR, you can make sure, that objects are in the centre, looking through the view-finder. The majority of chambers seems a short sound signal when the centre is locked and also to show a green rectangle round area on which they have concentrated. Always make sure, that this area - where objects of which you care. For example, if there are two objects in a scene in various distances from the chamber, make sure, that the chamber has concentrated on object which you want.
Indistinct photos: Indistinct photos are most probable result of shake-ups of the chamber. Learn how to consider, that your chamber minimises concussion: it should be spent firmly two hands, and it should "touch" your person. If you shoot at photos, using slow speeds of a shutter, you should use a strong tripod to prevent concussion. If you cannot guarantee, that the chamber will be steady – for example if you shoot, while you’re, moving – establish the chamber in a priority of a shutter and choose fast speed of a shutter (assuming certainly, that easy conditions allow such settlement), for example settlement of speed of a shutter to something faster, than 1/250 seconds most possibly guarantee not an indistinct photo even if the chamber will shiver a little.
The underexposed: Photos which are underexposed a dark sight and shortage details. The reason for the underexposed photos establishes podverganie too low. Though the chamber can measure surrounding light and to make of the decision podverganija for you, it can be mixed more difficult scenes. For example, if there is a source of very bright light in a photo, it can mix the chamber to believe, that there is enough light in a scene for low settlement podverganija. Result will be the photo which has grasped bright area, but blacks out all others. Usually you can assume, that scenes which have extreme intervals of illumination between various areas, confuse the chamber – for example if the photo quarter is very bright, and the others are very dark the chamber, possibly, will establish wrong podverganie. In such cases you can correct manually podverganie.
The superexposed: Photos which sverhvystavleny, have blown off areas and sometimes are completely sated also the white. The reasons for the superexposed photos are similar to the underexposed. The chamber makes the decision podverganija which is wrong because of difficult conditions of a scene. In such scenes you can correct manually podverganie.
The shaded objects: a good example of the shaded objects, taking a portrait photo in a daylight. The chamber measures enough surrounding light to establish low value podverganija. Though there are many enough surrounding easy shades, can appear on object depending on a corner of a light source concerning object. For example, if the person object’s is shined from the party, object’s the nose can create shades. Or it is possible if the object carries a hat and is shined from above hat, can create shades on the person object’s. The chamber cannot automatically correct such shades. Understanding, what shades of the reasons you can easily eliminate them, including flash of time replacement. Dismissal of flash of time replacement (make sure, that object within a flash range) will remove shades from object.
Red eye: It - very much the general phenomenon. Taking photos of people or animals, using flash in dark environment eyes have some red heat in them. Is a little prophetic, which you can make to prevent red eyes: some chambers support “red eye reduction” a way. That way the chamber starts flash some times before to take a photo. Though it can help a reducing red eye, it can lead also to photos of people their closed eyes (as they are blinded by preflash, their reflexion should close their eyes). Other ways to prevent a red eye consist in using flash of strong blow (you can make it with the special equipment or for example specifying flash on a white wall), and using more than surrounding light, if possible (for example, including all fires in a room). Some chambers include the built in software of processing of the image which automatically deletes a red eye from photos, or alternatively you can use many software packages on the house computer to reach the same.
Dark Silhouettes: taking photos with a source of bright light behind object (for example when the sun is behind object) the object silhouette will be result. One example takes a photo someone ashore against a decline. The dark silhouette of the person with a good photo of a background of a decline will be result. This problem can be solved, using flash of time replacement. Flash of time replacement shines object, making sure, that it is grasped with all its details. Simply do not forget to use flash of time replacement, removing objects with a source of bright light behind them. One restriction - that objects should be within a flash range – differently, flash is useless, and they will appear as silhouettes in a photo. |
