Here are some tips that you can use to take best pictures
The broader the light source, softer the light: it’s just opposite to the narrow light source. Narrow source needs harder light, because it hits only in one direction. Inspite of this, broad light source has more shadows, reduces contrast and suppress the texture. Broader light sources passes light in more that one direction and illuminates in broad way, and fills all the shadows. Place the object in dark place where you will not receive any sunlight.
The closer the light source, softer the light: For example when you take photography of people you can just move lights close to them and them you can take which will give you better illumination. Farther the light source, harder the light. Closer the light the picture might be broader and bigger. When you move the light father you will get only smaller pictures and that too in narrow. Another example is sun. Sun is bigger than earth but if you take picture from earth, it looks small.
Diffusion scatters light, essentially making the light source broader and therefore softer: For example, materials such as plastic or white fibres can be used as a diffuser in front of hard light. If you want to take picture in the sunlight, you can use some artificial diffuser so that hard light can become softer. When the clouds are before sun, shadows get separate. You can add fog, so that shadows can be removed. In the foggy days, it is easy to take pictures, than in normal days. The lights get softer.
Bouncing light acts as a diffusion: for eg, cut the aluminium foil and take the cardboard, place the foil in cardboard sheet, which is an best alternate for white light and this will give you broader image. You can use matte surface such as wall, ceiling etc., which not only reflects light but also scatters all over the surface. If you use shiny surface, the image will be in narrow type.
The farther the light source, the more it falls off— gets dimmer on your subject: When you move the light away from the source, it will get dimmer. When you move your light the quality of the source will also get changed.
Light falloff can be used to vary the relationship between the light on your subject and your background: When you move the light far away from the source your back ground will be brighter. When it is close, it will be better.
