The Exposure Triangle

September 24, 2017 Julia L Leave a comment

The exposure triangle is a common way of associating the three variables that determine the exposure of a photograph: aperture, shutter speed, and ISO.

Aperture: the size of the opening in the lens when a photo is taken. The opening controls how much light can enter your camera at once.

Shutter speed: the amount of time that the shutter is open. This amount of time controls the amount of time that light is allowed to hit the sensor.

ISO: the sensitivity of the photographic medium to light. In film cameras, this refers to how sensitive the film is to light and in digital cameras, it refers to how sensitive your camera’s digital sensor is to light. More sensitivity to light means less light is needed for a good expose of a photograph.

These 3 elements are tightly related. A change in one of the elements will impact the other two.

This means that each of the 3 elements is dependent on one another in order to come up with the correct exposure. Your camera has a light sensitivity level that is set by the ISO setting. To get the correct exposure, the lens opening needs to be adjusted to control the volume of light entering the camera. Then the shutter is opened for a certain period of time to allow the light to hit the sensor and record the image. Coming up with the correct exposure means combining the right blend of aperture, shutter speed and ISO settings.

Depth Of Field

September 22, 2017 Julia L Leave a comment

By changing the aperture in the lens, you can make the resulting picture have more of the picture in focus from near to far, or you can limit the picture’s focus in one place.

At ƒ1.8, the focus point will be much more defined with things in front of and behind the subject becoming softer looking further from the subject they are. This is a very nice way to bring attention to the subject.
At ƒ22, the focus will seem to be sharp from very close to the camera to pretty much infinity. This is great for giving a sense of the place you shot the image, or for including many people in the image and keeping everyone clearly in focus.

Experimenting With Shutter-Speed

September 21, 2017 Stanley Lucas Leave a comment

What is shutter-speed

Shutter speed (also known exposure time), stands for the length of time a camera shutter is open to expose light into the camera sensor. The faster the shutter speed, the easier it is to help freeze action completely, as seen by the picture of two birds.
However if the shutter speed is slow, it can create an effect called motion blur, where moving objects appear blurred along the direction of the motion, and can be used in things like advertisements for cars, motorbikes and nature, as seen below of the water.
I experimented myself with this blurred effect within school and this was the outcome:

I later tried using a long shutter speed at night on the road, to capture the lights of cars to a greater affect, and really produce a contrast between the darkness and the light. These were my outcomes:

Adobe Bridge – Basic Image Adjustments

September 21, 2017 Julia L Leave a comment

Adobe Bridge allows the user to quickly edit photos without the use of Photoshop, I’ll explain the functions and features of the process below.

After choosing you desired photo, left click and select “Open In Raw Camera”.

In the top right corner there is a histogram; a common way for adjusting an image is to spread out the pixel values more evenly from left to right on the histogram, instead of having them bunched up at one end or the other.

You can use the sliders to quickly adjust the different characteristic of the photograph, you can also manipulate the shape of the histogram – which corresponds to the different sliders. When you’re finished, simple press ‘save’.

Zone System

September 21, 2017 Megan Woolsgrove Leave a comment

The zone system is a technique formulated in the 1930s.

Benefits of Utilizing the Zone System

Capturing a correct exposure every time, even in the trickiest light or scene situations.
Having a precise evaluation of your scene’s tones and dynamic range prior to even making a shot.
Knowing when you need to use graduated neutral density filters.
Knowing exactly how far apart to take exposure bracketed shots for later blending.
Determining the situations where you need to use a fill flash to get a correct exposure.

Taking inspiration off of Ansel Adams, I tried to I incorporate all the different tones, from the darkest to the lightest, to make the photograph more interesting. The darkest point of the photograph is the middle towards the front of the photograph, showing black, whereas the lightest point is the top of the creased paper facing the natural light.

Typologies

What is typology?

Typologies. Typology is the study of types, and a photographic typology is a suite of images or related forms, shot in a consistent, repetitive manner.

For my new photography project two I will go more in depth about typologies artists . typolog to me is a way of expressing and journalism of many topic project of person you want To discover more about.A technique I see a lot if the gradual movement in order to observe and capture every angle to relate to a person and reflect the person in which they are living themselves.

Many examples are more reflected around line and person of people and differences and development of architecture. Throughout the modern era, photography has been enlisted to classify the world and its people. Driven by a belief in the scientific objectivity of photographic evidence, this is everything that can be captured within typology. The logics utilized to classify photographs-in groups and categories or sequences of identically organized images-also shape our visual consciousness.

Typology is a lesson that is revolved throughout a short series and is designed to encourage consideration of how photography can be developed and employed.It portrays the cameras ability to make a cultural human record of gradual development and accurately demonstrate a visual phenomena that the artist is seeking to portray to the world.It is also a systematic documentary of journalism of life and how the world develops and changes gradually, the photographer are used almost as a tool to witness and clarify evidence together in one place within one format. This is typological and a clear interpretation of the things surrounding yourself and others.

photoshop; tone and contrast

September 21, 2017 Orla Worthington Leave a comment

What is photoshop

This is to alter (a photographic image) digitally using image-editing software.It is done to exaggerate or dramatic change an image to connote and exaggerate a feel that wants to be expressed or brought forward to the audience.

How I achieved and edited my images

I achieved my images Using photoshop I wanted to developing deepening tone and texture to exaggeration depth within the image using layers.

Firstly I started off by inserting the image into photoshop in order to deepen the saturation and develop a more grip feel and not use the colour as a distraction for the image and circulation with patterns and line within the piece itself. Using the Crop tool, you can trim edges, change the shape and size of a photo, and even straighten a crooked line or the shape within the leaf. Furthermore Enhanced the quality and Brighten the photo and make its quality and highlights pop using adjustment layers. After layering the image ignorer to edit different aspect to then eventually flatten this image. I went onto a bast in order to move the saturation and so developing the colour to deepen the effect. I wanted to still be able to see sources of colour to not completely inveterate the colour within the leaf.I then costume the colours in a grain setting so would be able to accurately develop the colours and cancel out all the extras vibrancy that I did not want in my image. Finally I Convert color to black and white, add an old-fashioned tinted look, and play with focus using the Tilt-Shift Blur filter.

You can see the tool bars here in which I dimmed the saturation and colour to depth the image but also allowing the tone range from very black inner leaf to a progressive lighter leaf. You can also see the layers through the photo and how the custom levels about to be set to green to develop a deeper tone relevant to the piece.

Third and Best Edit

Overall this images now more effective as a whole and creates a better presence and does not direct form the image itself.It create s larger impact overall through the image and displays a larger impact of space and authority.

Tone and Contrast

Contrast is a measure of the difference in brightness between light and dark areas in a scene. This reflects a scene with significant contrast , whereas narrow lens reflect less contrast and may appear flat or dull. This can be caused by any combination of subject matter and lighting conditions.The is a great importance due to colour will only work effectively due to a good contrast.However countless images have been seen in black and white using this is a tangible element of compostion

Tone may consist of shadings from white-to-gray-to-black, or it may consist of darks against lights with little or no grays. The use of dark areas against light areas is a common method of adding the feeling of a third dimension to a two-dimensional black-and-white picture.This is also highly significant to the tonal range within the tone system

Shutter Speed

September 20, 2017 Julia L Leave a comment

What is it?

While Aperture is responsible for controlling how much amount of light passes through the lens, the Shutter Speed is responsible for controlling the length of time that the light is allowed to hit the camera’s sensor.

The shutter speed controls the amount of time that the shutter curtain is left open. The shutter speed gives you control over how motion is captured in your photograph.

Shutter speeds that are faster than your moving subject will create a photograph of the moving subject in a ‘frozen’ state. The photograph will come out with the subject being very sharp, in focus and seemingly in a stopped motion. You are basically capturing a split second image of the moving subject.

If, on the other hand, your shutter speed is slower than the moving subject then you will create a blurred image of your subject which generally represents a subject in motion.

Experimenting with long shutter speed:

Editing Using Photoshop

Editing Photos In Photoshop 

I had a go at editing some photos with the software called Photoshop, to see if I could enhance the looks of certain pictures with a few tweaks to their settings.
These were my results:



Before and after the picture has been edited (Edited top and unedited bottom).
 
























Before and after edited on Photoshop (Top image edited bottom unedited).

How did I edit them?

To edit my photos I went into the image and adjustments tab, located at the top of the screen, and selected what I wanted to edit

BRIGHTNESS/CONTRAST











EXPOSURE











LEVELS











Zone System 
















Above I used the Ansel Adams zone system (seen beneath), to identify the different areas of types of exposure, meant allow the photo to have the best contrast between light and dark as possible within the picture.



What is the Ansel Adams 'Zone System'?

The Zone System is a technique that was formulated by Ansel Adams and Fred Archer back in the 1930's. It is an approach to a standardized way of working that guarantees a correct exposure in every situation, even in the trickiest lighting conditions, such as black lighting, extreme difference between light and shadow areas of a scene, and many similar conditions that are most likely going to throw off your camera's metering, giving you a completely incorrect exposure.
