Using Aperture

– What does f-stop or aperture number do?

– It determines the depth of sharpness area of the image, or depth of field!

Shallow or wide strips of sharpness are obtained by using different f-stops. Shallow depth of field (using smaller f-stop numbers) means that the area of sharpness is very small and all other objects including nearer or farther objects are blurred in the image. Obviously, larger sharpness area is obtained as depth of field becomes deeper (using larger f-stop numbers). So, you can capture an object in near and far distance as sharp as it is, and leave everything else blurry. In contrast, you can capture a landscape with everything sharp in it, from near to far distance.

Image story: A pleasant Saturday morning walk in Victoria park, Auckland city, New Zealand. End of winter and there was no leaves on trees. These beautiful seeds, like black dots in white lines of tree branches made me think of using a shallow depth of field to capture the beauty of a single dot in a shot! I set the aperture of my lens on its widest, f/4, and shoot a dot. The original background of the image was green and I lightly touched the Hue of background to make this nature paint more eye catching.

Lines in Photography

– What is the impact of lines in photography?

– Lines contribute to the composition and mood of image!

Lines can create two-dimensional or even delusional three-dimensional environment in an image. Different properties of lines such as their angles, directions, density, curves, color, and thickness can significantly impact on image composition and mode. Although horizontal and vertical lines can create sense of stability, peace of mind, and permanency in an image, other types including perspective, angular, and irregular lines can act completely different as emotional triggers and attention grabbers (read this article for more details). Add to the list, lines can cooperate with other objects to put them in center of attention, push them to background, reduce or emphasis their impact, or simply fill their surrounding space.

Image story: Workers in general, and specifically painters bring peace and beauty into our daily life. I took this photo in Kota Kinabalu, Malaysia in my only trip to East Malaysia. I used parallel vertical lines together with emphasize on blue color to bring sense of peace into the image. On the other hand, I kept the simplicity of the image by removing unnecessary colors. This also helped me to transfer my message that “they bring color into our life, no matter how grey their life might be.”

Perspective Illusion

– What is perspective?

– Perspective is an illusion to present 3D space on 2D surface!

Although photograph is a 2D surface, it is capable of showing 3D space by applying perspective (Read more on Wikipedia). Point of view is very important to apply perspective in photography. Look into camera view finder and move from side to side of objects, buildings, and spaces to see the effect of point of view on perspective.

Image story: Damghan is an old city in Semnan province, Iran. It was an important city in the Middle Ages, and was the capital of the province of Qumis (Qoomes), but was destroyed by the Afghans in 1723. Few remnants of that time remain; one is the ruined Tari-khaneh mosque with a number of massive columns and wood carvings and two minarets of the 11th century (Read more on Wikipedia). I took this photo of inner courtyard of Tari-khaneh mosque when I visited Damghan in 2014. This specific point of view adds perspective to the shot and shows greatness of the structure. Some post-processing has been done to better show the age of the mosque.
