In Digital Photography ISO measures the sensitivity of the image sensor,  the lower the number the less sensitive your camera is to light and the finer the grain.

These photos are taken in a light area it goes in order: 1600, 800, 400, 200, 100.

These are photos are taken in a really dark light and once again goes in order: 1600, 800, 400, 200, 100.

What is White Balance?

‘White Balance means adjusting the colors so that the image looks more natural. We go through the process of adjusting colors to primarily get rid of color casts, in order to match the picture with what we saw when we took it. We do this because most light sources (the sun, light bulbs, flashlights, etc) do not emit purely white color and have a certain “color temperature“.  Proper camera white balance has to take into account the “color temperature” of a light source, which refers to the relative warmth or coolness of white light. Our eyes are very good at judging what is white under different light sources, but digital cameras often have great difficulty with auto white balance (AWB) — and can create unsightly blue, orange, or even green color casts.’

Video Explaining What White Balance is:

Experimenting with the White Balance, Inside and Outside

The first eight photographs where taken indoors, where I used every White Balance mode there was on my DSLR. These images consist of  artificial lighting, produced from the ceiling lights, due to this it makes the difference in White Balance a lot harder to recognise. However, the last eight photographs have been captured outside using natural lighting. This has allowed the different White Balances to be seen clearly.

Here are examples of my experimentation indoors:

These are all images of my experimentation of white balance. I adjusted the exposure so the photo wasn't too light or dark then applied the different settings which changed the temperature of the images.

Here are examples of my outdoor work:

In this experimentation shoot we had to focus on the depth of field of our photographs. Depth of field is the distance between the nearest and the furthest objects giving a focused image. Here are some examples of my experimental images:

In the first image contrasts the third image because the focus is on the object closest to the camera. However, in the third image, the focus is on the window which is the object furthest away from the camera.

The second and third image both link because they both focus on the objects/background furthest away from the camera. All of these images are an unedited experimentation of focal length.
