Camera flash is one of the main aspects you need to capture an image. The aim to use flash is to get better lighting source when you have to take a picture with poor lighting condition. However, using flash could also decrease the value of the image of photograph because of unnatural lighting could be considered the photo viewer. Therefore, you should be smart enough in using the camera’s flash to capture a picture.
If you think that you just need to capture an image without any artistic purpose using flash in relatively dark situation must be the best option you have. However, you cannot do the same for artistic purpose. For example, you need to take a picture of friends gathering inside a room. If it is possible, turning on the lights inside the room will much be better rather than activating the camera flash.
However, you still need to activate the flash for some moment. For example, when to object that you will capture stands in front of shiny background, the camera flash helps you to get better view of the for the object. You can try this by taking a picture of a friend standing on a store with bright lights in it. Compare the results of the picture by using flash and without flash.
