Final famous words



Although photography is not new to me, and I did experience the use of a digital camera, I always preferred to use the automatic mode for my photo-shoots. The main thing this unit tough me was not to be afraid of experimenting new things. I learned how to take my time, try taking one photo, examine it and re-adjust if need be; instead of clicking automatically and then realising I only have 2-3 usable photos.

I learned how ISO affect the background noise and can be used to create more interesting outcomes, in a creative manner that appeals to the eye rather than random outcomes that might look nice but have no creative meaning. Understanding how sensitivity to light creates different results and being able to manipulate the scene to my needs makes me feel I am in control of the scene instead of being controlled by it.

The ISO function is, to me, the true revelation of this course, as I really didn’t know anything about it before taking this unit.

Another thing I learned was basic terminology such as Exposure, Aperture, Shutter speed etc, which I then looked online for tutorials that can contribute to my understanding of the subjects learnt in class. Practicing those new skills allowed me to explore deeply and more thoroughly towards producing better photographs.



Shutter speed controls the time the shutter is open, allowing the image to “burn” into the sensor of the camera (before digital cameras, the image was burned onto the film).

Therefore, when she shutter opens for a brief of a second, the image burned will be clear (mostly used to capture bodies in motion like sports events, body in the air etc.) while when the shutter is open for longer, the image burned will be blurry. The shutter speeds measures in 1/x of a second, meaning that 1/3000 will let half as much light in than 1/1500.



Depth of field refers to how sharp the image or the object taken or how in focus they are. Depth of field is measured by the focus point. When the object stands in the focus point, meaning when it is the sharpest once a photograph is being taken, the further we adjust the Fpoint the deeper the depth of field will be, and the blurrier the background will show.

Focus point of F/1.8 will give us a deep depth of field, while focus point of F/1.6 will be a shallow depth of field and the objects in the background will be blurrier.

Depth of field is determined by the aperture size, the distance an object is from the lens and the focal length of the lens.



ISO is the camera’s sensitivity to light. The higher the ISO is, the grainier or “noisy” the background will appear. Unfortunately, in my camera, the highest ISO setting is 1600, which didn’t show the result I was hoping for.

White balance controls the resulted colour of the object under different light settings. Because the camera is not the human eye, the definition of “white” is schematic and not always realistic, therefore we need to define either what we consider white, so the camera can adjust object colour accordingly, or we need to define the (artificial) light we are using to make the object appear more natural.



Focal length (zoom) determines how much of the scene will be captured in the photo and how bit the objects will look. When we zoom in – fewer objects will be captured in the photo, and the object we do capture will look bigger. As we zoom out, more objects will be captured in the photo, but we will lose details.



Evaluation of my work:
There is no doubt my performance have significantly improved. My first photos (first blog entry), as much as I love them and they do look artistic to me, had nothing to do with understanding photography or the camera. The more I learned about photography and the more I practiced the use of aperture, white balance, ISO and shutter speed, I could create more usable photos and not just relaying on luck. I started this unit thinking I know a lot about photography, while, in fact, I mostly used the camera’s settings and not really gave much thought about what I can create and capture. I now know that I will use more manual function when taking photos.

Another thing that has changed since I took this unit is the amount of photos I am taking. While in the beginning of the unit I took over 200 photos to come up with four good ones, I now take about ten of the same scene to choose 3-4 good ones.

I can now operate the camera manually, understand and predict the outcomes of my work. I can control the scene rather than letting the scene control me, and take the time to plan before shooting.

Focal Lengths





I understand the logic behind wide images that contain full scenery; however I much prefer the close detailed ones. On this occasion, it mostly passes the feeling of an old private eye film noir.

ISO and White Balance


The task is to create 3 images that show creative use of camera’s ISO to add grain to the photograph.

My camera’s max ISO is 1600, and I have used both 1600 and 800 in my work.

I have created a series of photos using different settings of ISO to get the same object in different levels of noise:


Auto WB

ISO 1600

1/30 F5.6

 
Auto WB

ISO 400

1/30 F5.6

 
Auto WB

ISO 200

1/30 F5.6


I have also created a series of photos using different settings of White Balance to get the same object in different artificial colours:
ISO 1600

 1/30 F5.6

WB setting Shade

 
ISO 1600

 1/30 F5.6

WB setting Tungsten



 
ISO 1600

 1/30 F5.6

WB setting custom - All Servo
