Dices

Dice can generate random numbers. But, I set some numbers in aperture, shutter and ISO to get dices. The image could imitate as black and white photo except the red and blue dots. I have placed the dices in a black plastic folder. The folder was mixed of mate and glossy. Therefore, you can see small dust-like spots, and it could be negative impact to the image.

The aperture size was f/8 to reduce depth of field (DoF). Even though, there is simple DoF which I intentionally created. However, I feel a clean background and aperture size like f/16 would be ideal. BTW, I would like to share a quote from Navjot Singh Sidhu, "One who doesn't throw the dice can never expect to score a six."


Camera settings:

  • Aperture size: f/8
  • Shutter Speed: 1/200 sec.
  • ISO: 100
  • Focal length: 55mm
  • Flash: On

David and Goliath

I am going to talk about Biblical story or theological concept on David and Goliath. But, I am going to share some ideas of imagination and how we could turn the camera lens into our imagination. The following image was taken on a hilly area where I was about to find uneven surface.

Both of them were similar height. However, I call the person who in far distance as David and other one as Goliath. David was standing on low ground while Goliath was on high ground, and I was in low ground. It made perfect angle and cloudy sky which gave clear background.

It was clear sky and I was able to control the aperture. The aperture setting was f/11 on 21 mm focal length. These both settings were help to reduce depth of field that resulted to focus on both far and near objects or so called David and Goliath.

Camera settings:
Aperture size: f/11
Shutter Speed: 1/320
ISO: 200
Focal length: 21 mm

Bug on a flower

Actually, I tried to photograph the flower. The bug is a bonus. We plan something, but we get something else. It might be good or bad result. When I was focusing the flower, suddenly a bug landed on the flower. I did not a take time to think or see. I just clicked. If I was thinking, I might miss the bug.

Do you know after the rain atmosphere come more bright and clear?  It was a sunny day after rain. Even though, sky was not clear. Therefore, I was not able to control aperture and shutter speed. Due to 250mm focal length, I should have at least increased the shutter speed. The background was a maize field. Tele zoom lens is ideal for turning background into gradient or solid color. I was considering the rule of thirds and negative space. Therefore, I made space on left side.

Camera settings:
  • Aperture size: f/5.6
  • Shutter Speed: 1/60 sec.
  • ISO: 200
  • Focal length: 250mm

Orange Zinnia

I have captured this flower with kit lens. Ideally, macro lens or tele zoom lens is best option for photographing flowers. Both lens can give you control over depth of field.

It is an average click. There is nothing special on this image. I wanted to capture this beautiful orange Zinnia flower. However, I was not prepared and I had 18-55 mm kit lens, which is not ideal for this kind of shots. Therefore, I did some trick. I set focal length to 55 mm. The distance between lens and flower was 270 mm. Something is better than nothing!

Camera settings are as follows:
  • Aperture: f/8
  • Shutter speed: 1/125
  • ISO speed: 200
  • Focal length: 55 mm
  • Flash: Yes

Curry tree fruit

Do you know curry tree? Mostly, it uses for cooking in Indian and Asian cooking as flavor and as well as herbal remedy. Even if you know it, you would not see the fruit. Unripe fruit is reddish and fully ripe fruit is black as it in the picture.

Fortunately, I had light green background which is good for a black image. Actually, I utilized banana leaf as background. The leaf had about 2 meter long distance to the subject. 250 mm lens was good enough to turn the background with better DoF. Therefore, you cannot find distracting spot or marks on the background. I used in-built flash to get better light on the subject. 1.3 m long distance was perfect to the in-built flash. I clicked the image by considering the rule of thirds. Stalk is not in focus due to low number aperture, and shallow DoF is not good for this image. Also, flash reflection on the fruit is another negative factor.

Camera settings are as follows:

  • Aperture: f/5.6
  • Shutter speed: 1/60
  • ISO speed: 200
  • Focal length: 250 mm
  • Flash: Yes
