What is ISO?

What is ISO?

When you change your ISO setting  you're adjusting your camera's sensitivity to light (which can be anywhere from 24 to 6,400). This is the most important part of the camera  because it is responsible for gathering the light and transforming it into an image. If you were to use a higher  ISO number, the level of sensitivity will increase. However if you were to lower the ISO number, the level of sensitivity will decrease. Higher sensitivity is expensive but with increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. without a flash your camera may take too long to shoot, resulting in images that are blurry and out of focus.  Alternatively, a photographers  option is to increase the ISO number to 800 or higher. Some photographs are intentionally grainy/blurry to help create mood in a scene.

 

CANON 450D AND APERTURE, F-NUMBER AND SHUTTER SPEED

Canon 4050D

The twelve megapixel EOS 450D (Digital Rebel XSi) is a very similar camera to the EOS 400D, however there are a range of significant improvements; twelve megapixel CMOS sensor, 3.0" LCD monitor, Live View with both AF modes (contrast-detect and passive), 14-bit processing and RAW, spot metering, improved AF, 3.5 fps continuous shooting, a larger viewfinder, SD/SDHC storage and a new higher capacity battery. All in all a fairly impressive range of usage oriented improvements and refinements.

Aperture:

Aperture is a hole where light can pass through. The aperture of a photographic lens is a hole that can be adjusted to different sizes. This lets the photographer control the amount of light reaching the image sensor. The aperture is changed along with the shutter speed to control the amount of light that enters the camera. This amount of light is called the exposure.

F-number:

The size of the aperture is described as an "f-number." This is a number that describes the size of the hole proportional to the focal length of the lens. A low number (such as f1.4 or f2.8) means the aperture is wide open, and lets in a lot of light. A high number (such as f8 or f11) means that the aperture is small, and does not let in as much light.

Shutter Speed:

A fast shutter speed will not let much light in causing the picture to be dark, so the photographer will use a larger aperture to correct for this. A slow shutter speed will need a smaller aperture to stop the picture coming out bright. In addition to its effect on exposure, the shutter speed changes the way movement appears in photographs. Very short shutter speeds can be used to freeze fast-moving subjects, for example at sporting events or light pictures. Very long shutter speeds are used to intentionally blur a moving subject for artistic effect.

SELF IMAGE: Shadi Ghadirian 'Like Everyday'

Shadi Ghadirian 'Like Everyday'

Ghadirian challenges the international preconceptions of women’s roles within an Islamic state, her photographs draw from her own experiences as a modern woman living within the ancient codes of Shariah law. Ghadirian’s everyday objects become a group of distinctive portraits, wiping away her identity using these objects (such as irons and frying pans) to create a brand new stereotype-based one.
Her 'Like Everyday' Series was created from the domestic gifts she received after her wedding. Ghadirian’s photos  portray an interpretation of  housewives, reducing their identities to cooks and cleaners.
Replacing the expected  black chador with vibrantly patterned fabrics, each portrait suggests a sense of individuality and character, however restricted by the limitations of stereotype.

 

 Shadi Ghadirian example

My version of 'Like Everyday' is a statement about stereotypical teenagers 'always being on their phones'.

In this photograph my identity has been taken away an replaced with an iphone, also my uniform has the same effect because it does not show individuality.

SELF IMAGE: Jesper Molin 'Somebody or Nobody'

Jesper Molin 'Somebody or Nobody'

Jesper Molin studied photography and art at the photography school in Gothenburg. He creates photographs with reflection, light and expression. The Swedish photographer said 'As long as the expression creates a feeling it creates art.'
In the picture below Jesper took one photo from the front and then played with it to make it perfectly symmetrical on both sides. It resulted in him having two pictures, one of two right sides and one of two left sides, making two completely different pictures of the same person. I think this type of art symbolizes the fact that nobody is perfect or symmetrical and that each person has two sides to them weather it be ugly/nice/broad/narrow.

Jesper Molin example

I made my own 'Molin' style photographs of both my left and right sides using Photoshop. I used techniques such as duplicating layers, removing the colour and flipping horizontally to create two separate pictures.

This is another Jesper Molin edit that I tried for the 'self image' project. I feel that this is a successful piece because I have taken a famous face (Beyoncé) and turned it into something almost unrecognisable. This is very effective in getting the 'somebody or nobody' message across because it shows how even someone that is idolised by a huge proportion of the western population, it doesn't correspond with the way we measure beauty. It could also suggest how we are expected to be consistent throughout by not having a 'split personality' but this project shows how have all different personality trates which makes up who we are and that perfection doesn't always come from being physically symmetrical.
