Thanks to flash, you can have a light source lights albums as you please. However, if we take maximum lights albums possible advantage of the light source, we complicate life a little. There are different kinds of flash, and each well used, it may be appropriate for one type of photography, and can afford to achieve very different results. This chapter initially discuss the characteristics of an integrated flash, and then we will focus on compact flashes, which are the most popular, trying to classify them according to their performance. Finally, we also devote a few lines to ring flash, ideal for macro photography.
We call that incorporate integrated flash compact cameras and most SLR cameras. Its main features are: To be included in the camera saves considerable, and the added convenience of always turn to him. The light source is usually small, so in portraits and photographs to nearby objects can create harsh shadows, maybe we do not like from an artistic point of view. Moreover, usually close to the target. For this reason the projected light is very flat, and sometimes gives the impression of reducing the volume of the subject we are photographing. In a portrait, for example, will show a flatter factions. This lighting always has an artificial appearance. In most cameras this flash operates automatically. lights albums This may be a limitation if we want to take pictures with a more or less intense lights albums light than usual, since we can not configure it manually. In most SLRs, however, although the built-in flash is also automatic, can be partially set the intensity of exposure from the camera menus. Its power is quite limited. This means that from a distance, it will be difficult to get properly illuminate the scene. That is why, if we are not careful, we can have trepidadas or underexposed photos. In any case, if you need the flash to illuminate a scene nearby (a group portrait, night, for example) as a souvenir and without major artistic pretensions, this is our flash, no doubt.
Despite being a bit simple and configurable tool, the integrated flash can get us some trouble, without major complications. Most cameras do not allow this use another flash.
The compact flash is a standalone device that connects to the camera through a pad located on top of it. All SLR cameras lights albums have a hot shoe for connecting this type of flash, like a few high-end compact cameras. Within the compact flashes there are different ranges and features.
For simplicity, we can say that the main features of a compact flash BASIC are: The torch is higher and higher, which is having a major source of light. This is important because lights albums although the shadows remain harsh, they are somewhat less than with the integrated flash. Many also incorporate a removable diffuser, which can be used to uniformly illuminate a scene from wide angle. They have more power (guide number), and therefore a greater range. They also tend to have higher refresh rate. Generally, the head can swing in the horizontal and vertical axes. This is probably the most important feature, since it will allow us to "bounce" flash firing into walls and ceilings, thus achieving enlightenment, not only blurred and balanced, but also personalized. In the same way that a frontal flash can flatten a subject, a bounced flash can increase its volume and texture. Thanks to this, get a much more natural light, and the creative possibilities of using flash multiply. We are no longer talking about using the flash when there is no light, but to shape it to our liking.
The performance of some models are superior and varied. We can say that the main features of a compact flash ADVANCED are: A high-end compact flash usually be used with manual control. This may seem unnecessary when you just want to take a picture with a front mounted camera flash, lights albums but nevertheless can give us tremendous lights albums flexibility when working in the studio or combine several flashes and accessories. An advanced flash often means more power, better lights albums construction and higher lights albums refresh rate. This allows us to achieve the desired light at longer distances, or more small apertures, and also use the flash burst pictures. Faster synchronization. This is
