Camera Settings Evidence Template

ISO Settings

The Iso is a measurement of the sensitivity to light. If you have a lower iso, for example something like 100 ISO is deemed insensitive and will need to allow a large amount of light in. The benefit of using a lower ISO is that the image is generally of a much better quality, as can be seen from my images on the left. The 100 ISO image is significantly clearer than the other pictures. Selecting a low ISO will also allow you to select a lower shutter speed as selecting a high shutter speed will not allow enough light into the photograph.If the ISO of the picture is higher for example 800 ISO upon zooming in on the image you will notice significantly more amounts of noise and possible colour loss. However a higher ISO is perfect for shooting things like sports as the image is instant. 100 ISO400 ISO800 ISO1600 ISO or higher

It also allows for low light or non flash photography. ISO is part of something known as the exposure triangle with Aperture and Shutter speed being the other two parts. Using all three of these correctly can dramatically effect the quality of your image which is why its best to understand how each setting effects your photo before selecting them.

White Balance

As you can see from the images above, selecting a different white balance setting can dramatically change the outcome of your picture. The majority of the time using the default Auto WB is fine for almost any type of photograph, however sometimes you might want to experiment and see what other outcomes you can create. Thinks like Cloudy And Shade seem to make the picture a little brighter giving it a warmer feel. Both of these options are optimally used when either its a cloudy day or you are shooting a subject that is in the shade.Tungsten is an option which is primarily used for shoots that are indoors. The given effect is that of a cooler image, taking out some of the brighter more harsh tones and giving it a more cool, blue style.The Fluorescent WB is a mode that is used for getting warmer and brighter shots whilst still compensating for the cool shade of fluorescent light. This option and tungsten are relatively similar however you can see the slightly warmer colour tones in the fluorescent option.The flash option is one that most will be familiar with, it allows you to take the picture you want in low/no light situations. It actually looks very similar to cloudy and daylight WB.

White Balance

Overall there are a variety of different white balances that you can experiment with to see how your photograph would look if it were taken in a variety of different lights. Some of these are great for low light photography whilst others give the optimal result when used outside in higher light situations.

Shutter Speed Control

The Shutter Speed is a control which dictates the length of time that light is allowed to hit the sensor. One key thing to remember with shutter speed is that to get the best image then you must compensate for the shutter speed by changing other settings in the exposure triangle.As you can see when using a longer shutter speed such as 1 second you can see that the subjects in the image becoming a blurred image showing their movement. The image is also considerably brighter than the others, this is due to the fact that I didn't alter the aperture or ISO so the image took in a lot of light leading to the brighter picture.You get a similar blurred result in the 1/15 setting. However the image is very slightly darker as not as much light was involved and the blur is perhaps not quite as heavy as the 1 second or longer image.

Shutter speed of : 1 second or longer Shutter speed of : 1/15 to 1/60 secondShutter speed of : 1/250 secondShutter speed of : 1/2000 or higher

Shutter Speed Control

The shutter speed of 1/250 began to give a blurred effect simlar to that of the longer shutter speeds but not of the same intensity. The image again , is significantly darker which goes hand in hand with the correlation between the longer shutter speeds and the intensity of the light.Finally the 1/2000 shutter sped, is pretty much an instantaneous image which give a nice crisp image with virtually no blur. The images that were taken at a longer shutter speed had to be taken with a tripod to ensure stability. Longer shutter speeds are ideal for things like architectural photography or photographing things like the weather. The faster shutter speeds don't rely on the tripod as much and can be done by hand, faster shutter speeds are great for taking quick photographs of things such as sports or animals.

Lens Aperture Settings (Depth of Field)

The aperture is the size of the hole that is allowing light into the camera when you are taking a photograph. A good way to think about it is to think about your eye. Your brain will automatically change the dilation of your pupils to allow in the correct amount of light. IF you are in a dark room the pupils will widen to allow more light helping you to see, the opposite if you are in a well lit place.Widest Aperture (f/4)Medium Aperture (f/8)Smallest Aperture (f/16)

Changing the aperture as I said, changes the size of the hole which lets light in, so combining the aperture with the other two aspects of the exposure triangle you can get an interesting variety of pictures. In the pictures I took I solely changed the Aperture settings. As you can see the Wider apertures allow for a shallower depth of field, the strap of the camera as photographed here is totally in focus where as the background is heavily blurred out. The medium aperture has a slightly lessened effect but you can still see some noticeable blurring in the background of the image.

The smallest aperture ensures almost no blurring and allows the entire picture to be sharp. Some people prefer it this way where as others will prefer to experiment with depth of field.
