White Balance and Colour Temperature
Whit balance is when you remove any colours in a picture/video that are unrealistic, making the photo/video seem more realistic and natural looking. Without the correct white balance the picture will look a weird unnatural tone of colour and not very realistic. Colour temperature is measured in ‘kelvins’, its basically that different light sources emit different colours. Inside is tungsten light witch is more of a yellow/orangery colour, and is mainly lamps and artificial light, out side light is day light and that has more of a blue colour and is mainly from the sun witch is outside.
Three poin lighting
Three point lighting is a very common lighting. It is three lights in a triangle shape around a subject. The 3 lights are the key light, fill light and back light. They key light points at the subject, and this is the brightest light. Then the fill light witch is sofer, ot some times just a reflector and is placed on the oppisite side of the fill light, this is to fill in the shadows. Then there is a back light and this is placed at the back of the subject to sperate them from the back drop and create depth.
For this task we had to find three locations in college and take 6 different photos using the different white balance settings on the camera. The first location we used was inside the college but placed a chair by a window so we had both inside and out side light. The second location we used was in the media corridor witch was just inside lighting, then we went out side and look pictures of a sculpture witch was all outside light.
Auto White Balance
For this task we got showed how to use reflectors. They used three colours, gold, silver and white. We took 3 different pictures using each colour putting the reflectors in different positions. One from above, one from the side and one from the bottom.
