Technical controls P3 (b)


An example of an Exposure triangle





An example of Aperture speed settings - f2 (lets in more light) - f16 (doesn't let in a lot of light)




Here are some unsuccessful shots we took in class: 



Shutter speed: The shutter speed was at 12.3 sec for this image, so it is set so that it won't let too much light in, but will still let some in. The aperture was set at f/22 which will let less light in, but should put everything in focus, but in this image it's blurry, which suggests that the camera was moved when the picture was being taken. 



This image is over-exposed. Even though the aperture value, shutter speed and ISO speed settings stayed the same at the image above, they are still different. This is because the light for the image was closer to the table. We found that this made all the images that we took, to bright and over-exposed, so we decided to take the light away which gave us better results.

Wide shot and Fish-eye image analysis


Wide shot images:





For these three images above were taken with a wide lens. This lens covered more area with one shot and allowed a wider range of ground to be taken.

White balance

For this task we worked on setting the custom white balance settings on ours cameras. We started off by taking a picture of a white sheet of paper, then setting that picture on the camera as the white balance. We then took pictures of an object, I used a pumpkin, changing the white balance settings from, 'Auto, Daylight, Shade, Cloudy, twilight, sunset, Tungsten light, White fluorescent light Flash use, Custom, Colour temperature.' The images on these settings came out in different colours.

The pumpkin I took pictures of with the different settings:

For this image I used the 'custom' setting on the camera. The photo came up normal so the 'custom' setting worked well with the white balance I had set inside. 


For this image I still used the custom setting, but for some reason, it came up in a different colour, more blue. This is because I had set the white balance again and it adjusted to that, setting it at the white balance.


For this image I used the 'White Florescent Light' setting and the picture came up in a purply colour. This shows how this setting reacts to the white balance I had set for the camera.

For this image, I used the Tungsten Setting.


We then went outside and did the same thing and took a picture of a white sheet of paper in the sun and set it as the white balance for the camera. I then took a picture of the same place with the different settings and they came up again with different colours.
