WHITE BALANCE PROJECT

White balance

What is White Balance?

White balance is when you adjust the colours of your image which helps to make it look more natural. This is done through the process of adjusting colours to get rid of colour casts which helps to match the picture with what we saw when taking it. This is done due to the light ( sun outside and lights inside) giving a pure white colour to out photographs due to the ‘ colour temperature’. The digital camera is not very good at determining when a picture is turning white unlike our human eye. Therefore, the camera can create orange and blue colour casts to help make pictures more visible.

The different White Balances- AUTO is the automatic mode of White Balance where the camera is the one to decide which mode is best for where you are taking images. The FLASH White Balance helps to warm up your picture to stop the images being very white and washed out. The CLOUDY setting help to warm up your images and stop them coming out very pale like the DAYLIGHT mode does. The TUNGSTEN is used indoors under artificial lighting as it helps to give your image a very ‘cool’ effect which is the opposite to the FLUORESCENT White balance which warms up images.

When taking my images i used a high shutter speed to stop images being overly exposed.

Experimenting with White Balance inside.  

The first six photos i took were inside and were taken with every White Balance mode on the DSLR. The images were taken with artificial lighting which made it very hard to recognize the White Balance.

Experimenting with the White Balance outside.

The next six photos i took were based outside which helped to show the White Balance a lot more due to the natural lighting. The natural lighting also helped to make more of an identification of the different colours that each mode had.

ISO

Leave a comment

ISO stands for International Standard Organisation.

ISO is a number that indicates how sensitive your camera is to the available light.  The ISO ratings are auto,100, 200, 400, 800, 1600, 3200, 6400. The ISO setting is directly set up with your shutter speed and aperture setting, to make the photos properly exposed. When the ISO rate is higher less light would be needed to obtain enough exposure. Over all changing the ISO settings on the camera increases or decreases the sensitivity and light gathering ability

WEEK 4- CAMERA SKILLS ( MANUAL FOCUS)

Leave a comment

Camera skills- Manual focus

Manual focus is a camera setting which helps you to focus on one object in a picture you are photographing manually. Photographing manually means that the object you are taking a picture of isn’t necessarily focused on your camera at most points like it is using auto focus. Manual focus will take a lot of time, however is a very good setting to use as it is very good at capturing still objects.

Using manual focus i was able to take picture of this old rusted bird cage while focusing on different parts of the cage, as well as the spider web which was inside. Using the different depth of field is helping to manipulate the audience.

White Balance

Leave a comment

White balance is a camera setting where you are able to choose the best colour setting for taking pictures in your location so you are able to get the colour in your pictures as accurate as possible.  On my specific camera there were 5 different options; Auto, Tungsten, florescent, daylight, cloudy and flash.

Auto is the automatic mode where the camera will decide which mode is the best based on where you are shooting. Tungsten is mostly used to shoot indoors under household lighting, as it  usually cools down a picture. I noticed that the florescent mode warmed up my images. Daylight mode makes your images have a fairly normal white type of filter. The cloudy mode made my images look similar, except it warmed it up slightly more.  Usually when you take pictures using flash, it can make your images turn out quite white and washed out. The flash white balance warms your images up a bit more to reverse this.

When taking images using certain WB settings, its important to have the correct shutter speed. If its too slow, your images turn out too overexposed. This happened while i was experimenting with my images, as you are able to see from my contact sheet.

Manual focus

Leave a comment

Manual focus is a camera setting where you have to focus on things you’re trying to photograph manually.  This means that objects will not be automatically focused every time you point your camera at it, like they are with auto focus. Although this may be inconvenient at some times, it a good setting to use if you are trying to capture still things where can can afford to spend some extra time trying to focus on it correctly. This setting allows you to be able to focus on different things in your location. As you can see from my contact sheets I firstly photographed fruit. With the manual focus, I was able to individually focus on different pieces of fruit by adjusting the lens. I was even able to focus on the background of my images, Meaning that the objects in front were completely out of focus. With this setting you are able to manipulate your audience’s focus when they look at an image.

As you can see, this contact sheet contains different variations of the same image. I didn’t move my camera but for each one i adjusted the manual focus so that it focused on different parts of the scene.

ISO Experimentation

Leave a comment

By changing the ISO setting of a camera, the camera sensitivity to light changes. By increasing the number on the ISO setting, the camera becomes more sensitive to light, and so photographs can be taken in darker areas without the need for flash.

ISO is useful for taking photographs, as rather than using flash, and making the image seem more artificial, ISO makes use of the natural light already in the scene, and so makes the photograph look more natural.

However, using a high ISO setting can also add to the noise of the photograph, lowering the quality of the image overall. That is why it is important to carefully decide how high the ISO is set, depending on the setting that the photograph is being taken in.

For my experimentation, I used the same subject, while changing the ISO setting. In order to allow each photograph the same amount of light, I changed the shutter speed as I increased the ISO.  The results of 5 different photographs, ranging from ISO 400-6400 can be seen below.

As I raised the ISO, the photograph became darker, and so to counteract this I also gradually decreased the shutter speed, from 1/10 to 1/100. This allowed for the same amount of light in each image. 

In the above 2 images, the difference between the ISO was large (the first one had an ISO of 400, and the second of ISO 6400). The bottom image is clearly more sensitive to light, as it has made the image brighter without the use of flash, whereas the image above is less sensitive to light, and so the image appears to be darker.

The above images were both taken of the same leaf, yet the first image clearly has more noise than the second. This is because the first image was taken using ISO 6400, and the second taken using ISO 400. Although using a higher ISO allows for for camera to become more light sensitive, the amount of noise in the photographs taken with this higher ISO makes the image seem blurry and low in quality due to the extra noise produced.

What is ISO?

The ISO on a digital camera allows the user to control how light sensitive the camera is.

The lower the ISO, the less light sensitive the camera is.

The higher the ISO, the more light sensitive the camera is.

Advantages:

The ISO allows the user to take photos in bright areas with a low ISO and in darker areas with an increased ISO.

Disadvantages:

When the ISO is increased, the quality of the images will be poorer. The images become grainy, less sharp and will have decreased amounts of detail.

Examples:

  • 1/200
  • F5.6

ISO 100

ISO 400

ISO 1600

ISO 6400
