Digital Photography Technology Tutor-Marked Assignment Report - SUSS

This report analyzes two photographs, "River Giants, Crystal" and "Singapore Skyline," examining the technical and aesthetic elements of digital photography. The first section discusses the use of ISO 200 for optimal image quality, the shutter speed (1/1600s) to freeze motion, and the aperture (F2.8) to achieve a shallow depth of field. It also explores the design element of texture, emphasizing lighting to enhance the image. The second section focuses on the "Singapore Skyline" photo, explaining the use of Neutral Density (ND) filters to smooth water surfaces and the rationale behind the camera settings. The report references key concepts such as camera shake, fast lens cameras, and the impact of aperture on background blur, providing a comprehensive analysis of photographic techniques and principles.

QUESTION 1 – RIVER GIANTS, CRYSTAL
ISO
a) The picture in figure 2 utilizes ISO 200.
b) This is because the highest quality output has been achieved from the
camera. This image evidently contains details such as shadows and it is characterized by
a dynamic range of better colours; this is only achieved by having a lower ISO.
Having a higher ISO means the picture will translate to a grainy or noisy image.
Furthermore, the higher the ISO when taking a picture, means that there is a higher
sensitivity to light. Taking an image with ISO 800 means that the image will be 4 times
sensitive to light compared with one that is taken with ISO 200 (Banterle, Artusi,
Debattista & Chalmers, 2017).
Shutter Speed
a). The shutter Speed used was Shutter Speed 3 (1/1600s)
b). Shutter speed allows a photographer to freeze a moment in time and have the
control of his or her images (Vollmer & Möllmann, 2011). When holding your camera
with bare hands, you would want to use a lower shutter speed in order to account for
general camera shake when pushing the shutter button. However, the image in figure 2
must have been taken with a higher shutter speed probably 1/1600. This is because the
photographer had to freeze the faster movement of splashing water. When freezing fast-
moving objects, a higher shutter speed is required. In order to ensure a good image with a
higher shutter speed, a tripod also must be used to get rid of any cases of a shaking
camera. Higher shutter speed also means that less light will get into the camera. This
way, fast lens cameras need to be used in order to capture such images. Fast lens cameras

have wide apertures which allow more light to get into the camera, this will in the end
account or compensate for the high shutter speeds.
Aperture
a) The Aperture speed utilized in the image is APERTURE 1 (F 2.8).
b) The depth of field of this image is shallow; that is, the background is
completely out of focus. Having a much smaller aperture means that the entire picture
from back to front will appear sharp with no out of focus background. Smaller apertures
result in a small amount of background blur and are good for architectural images or
landscapes. But in the image River Giants by Jack Long, a bigger aperture of F2.8 was
used in order to bring a clear concentration of the splashing water by having a blurred
background.
Design Element
a) Texture
b) Texture is one design element that has the ability of moving our deep
emotions in a picture. Texture has been well utilized in this image by having an
appropriate lighting element. This element is accentuated by the side light of early sunny
mornings or early evenings. Figure 2, was taken in the morning probably around 11:00
am; this is because shadows of the trees are emphasized along the surface of water
bringing more depth, interest and reality into the shot.

QUESTION 2 – TRANSITION
Photo Title
Singapore Skyline
Background
The picture below was taken in Singapore at the outdoor theatre of Esplanade. It was
taken in the morning just after run rise.
Rationale
Neutral Density (ND) filters were used in order to get a smooth water surface by
smoothing out the ripples on the water surface while using a lower shutter speed (Czajkowski &
Schmid, 2017). A lower shutter speed without neutral density filters technically will not be able
to freeze efficiently moving objects like the ripples on the water surface in this picture. In the
foreground, we have achieved a smooth water surface without any ripples by utilizing ND filters
(Smoother transitions). In the Middle ground, and background, we have a clear picture that has
nothing blurred. We achieved this by using a smaller aperture and a lower ISO.
