The photographic world is divided on whether to always use the flash but personally I find it a pointless diatribe, the flash should be used if needed as long as you know and know how to "tame".
should first be admitted without hesitation that a photograph taken with only the light environment is more pleasant and harmonious a shot with the help of flash but there are situations where you can not do without and still there are tricks to make it soft lightning.
The classic case in which a flash in the correct way is the difference is the picture, this kind of photography in a strong, direct light will highlight the hard features of the subject because it will create light and shade of very dark shadows may give the subject's face looks very smooth. In such a situation, we must first see that we have flash, if that fixed on the camera or an external one.
FIXED FLASH: the little flash mounted on the machine, but has a reduced power for "normal" situation and also more than adequate for portraits can be used with satisfaction as long as you use the devices. Almost all machines have a function that is used to adjust the intensity of the small flash drive that usually varies in a scale ranging from -2 to +2, this is very useful because it allows us to measure out the light in an appropriate manner . If our subject is a few meters from us it will be useless and harmful shot him too powerful a flash as if the distance is greater, then we will agree to raise the intensity. Unfortunately there are no precise data, depends on the flash and his power then I recommend to experiment by placing a subject at a fixed distance and take pictures only going to intervene on the power of flash to get an idea of \u200b\u200bhow and what changes the final result.
A trick to soften the light and make the flash less obtrusive is to put flash in front of a piece of parchment paper or more pieces until the desired intensity, is a very homely but functional and cheap, remember to use only baking paper and to not touch it during or immediately after the flash because the flash is very hot!
Pay attention to the shade of your goal, because the flash integrated very low compared to the body you risk seeing a shadow in the lower part of the shot ... it is the hood!
EXTERNAL FLASH: This type of flash is mounted on the slide on most cameras except the compact pocket and offers significant benefits. There are many types and prices vary in power and jointed It ranges from the cheapest that can only be raised or lowered on the vertical axis to reach those that can rotate on the horizontal axis and remotely controlled from the machine . Prices vary greatly, you can find flash from 150 € up to those of more than 600 ... it all depends on what you need of course.
To begin it well enough and you will see a statement that the results will be very different from those of the integrated flash.
If you are at home the external flash has the great advantage that it can be pointed at the ceiling or to a side wall.
Why do it? Just to try to recreate a natural atmosphere in which the subject will not be overwhelmed by the light directly, but it's come back, through walls, and behind him giving more photogenic to shoot. This arrangement also allows the determination of the shadows so soft and selective, for example, if the person has an imperfection on the left side of the face I'm not going to illuminate the but I'll leave it in the shadow stressing other parts of the face or at least focusing the light on the good side.
addition to the flash point sideways or upwards, you can also buy speakers to ask yourself before, are nothing more than white or colored caps that are used to make more diffused light and soft, ideal for portraits or macro shots however, close and cheap, that will not hurt.
I personally think the flash last resort, for use when the picture must be taken to the home you can afford and do not blur because the situation does not repeat itself but is an option to not discard a priori by party taken. Everyone loves you always shoot light environment and this has sparked a race to the high sensitivity that is not only absurd it is unnecessary for the quality of the shot. Remember that fact as they go up with the ISO to clean the picture will be affected while using a flash you shoot at low iso using a very short time to freeze the moment.
I found myself photographed on stage sometimes, I also have chosen not to use the flash because the spotlight, however, allows you to make a quick shot, but at what price? Sacrificing the cleaning of the shot and thus precluding the possibility of crop and edit it later so I always chose to use the flash with the appropriate Speaker looking for photos to make less noise but not to bring home the result of better quality.
This aspect should be considered, if you find that the flash bothers those around us we have to turn it off and, if necessary, store your camera, the photographer is not entitled to disturb others to satisfy his passion, always remember that if you want people to appreciate what you do.
