Camera Use Week 2 Aperture Exercises

In Class Aperture Exercises:

Shallow Depth of Field = Low F Stop Number
Great Depth of Field = High F Stop Number

In Class Exercise:

All of my photographs on this page were taken with the below settings:

Camera Setting: Shutter Priority: (TV)
Quality Setting: RAW and JPEG

Colour Balance: Adobe RGB
ISO: 100 - as we were shooting outside
White Balance: Auto
Focus: Automatic

Wide D.O.F Portrait - using a small aperture [f/4.0]

Shallow D.O.F Portrait - using large aperture [f/1.4]

Wide D.O.F Landscape - using small aperture [f/4.0]

3 - Element Photographs: -  using [f/20]

Foreground Focus:

 Mid ground Focus:

 Background Focus:

Wide D.O.F Environmental Portrait - using small aperture [f/5.4]

Wide D.O.F Object Portrait - using large aperture [f/11]

 Shallow D.O.F Object Portrait - using small aperture [f/4 and 50mm lens]

When comparing these two padlock images, and with the above plain hallway image, I have noticed a big difference in Depth of Field and in photo blur. In the first photograph of the hallway, using f/4.0 and a 46mm lens, I noticed that there was more blur to the photograph than when I used the same settings but with the 50mm lens (above). My guess is this is the difference between both the lens' and how they function. But when I used a higher f/stop (f/11) with the same 46mm lens, I noticed a slight difference because I was focusing on a padlock instead of the door at the end of the hallway, but I also noticed an exaggeration in the Depth of Field. With the higher f-stop number, the more blurred the area of the photograph that was out of focus became.

Self Directed Tasks:

The following Self-Directed Tasks were shot using AV mode (Aperture Priority Mode).
The Camera Settings differed slightly from that of the In Class Exercises (TV to AV Mode and ISO fluctuated depending on task).
The Artist Model for this task is Vanessa Wu. Some of her work is below.

1. Photograph Emulation
I attempted to emulate Wu's above still life photographs as best as I could and used a shallow depth of field.

2. Night Photographs:
The following photograph was shot at 100 ISO and I used a tripod.
The noise level is quite low in this photograph.

These first two photos have different depths of field. The day-shot one definitely has a slightly more shallow depth of field in comparison to the second night-shot one. I think this is because of the lighting and there not being enough of it in the second shot.

The following photograph was shot at 12800 ISO and I used a tripod.

I find that the higher the ISO Level, the more is in the photograph. Therefore, the noise level in this photograph is very high.

3. Daytime Scene

The following photograph was shot at 100 ISO and I used a tripod.
The noise level is lower in this photograph compared to the photograph under neath it.
They were both taken with opposing ISO numbers therefore the noise results are at both ends of the noise level amount.

The following photograph was shot at 12800 ISO and I used a tripod.

Noise Level Quality:

I found that the higher the ISO - the lower the quality of a photograph is. This is because, with increased noise, the image becomes more 'pixelated' and therefore less defined - creating a softer image, which makes the quality of the image decrease.
