Aperture/ Depth of Field

Image result for aperture

Aperture relates to the size of the whole/ diaphragm in the lens, this is measure in units called f stops.. The lower the number the wider the aperture (for example f1.8) therefore allowing lots of light in through the lens compared to a small aperture of f22 which restricts the amount of light being let in. When taking photos or videos, the aperture also determines the depth of field, for example: a wide aperture of f2.8 creates a shallow depth of field, isolating the subject making the background look blurred. Conversely a small aperture of f22 for example has a deeper depth of field making the whole image in focus.

F22 makes everything in focus.

Aperture/Depth of field

Aperture refers to the opening of a lens’s diaphragm through which light passes. It is calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16. Depth of field is the distance between the closest and farthest objects in a photo that appears acceptably sharp. Now your camera can only focus sharply at one point. But the transition from sharp to unsharp is gradual, and the term ‘acceptably sharp’ is a loose one!

landscape photoshoot

Shoot 1,2,3 and 4

Best images:

These images proved to be the most successful out of the 4 shoots, as they were clearly taken (no evidence of camera shake compared to the other photographs taken), the majority also show large structures associated with romanticism in landscape photography.

Editing process:

For the image above, I increased the temperature, highlights and contrast to accentuate the detail on the rocks and to make the water in the foreground of the image stand out. These adjustments also helped to outline the shape of the clouds in the top third.

For this image, I wanted to focus on the green aspects of the landscape. Decreasing the brightness and increasing the saturation of the image brought out a range of green tones, which helped add atmospheric depth to the image. The increase in contrast and sharpness of the photo during the editing process helped to focus on the stones in the foreground and bring attention to the brown hue of the river beneath it. The deep colour of water breaks up the photo, drawing the viewer’s eyes away from the green of the leaves and foliage, making them look over different parts of the image.

This image pictured above already had features I was satisfied with. I felt as though the photo would benefit from an increase in colour in the sand. To achieve this I increased the saturation, made the temperature of the image warmer and increased the contrast and shadows slightly to bring out the oranges and beiges in the rockfaces and sand.

In this image, I wanted to bring out the oranges and dark amber colours of the cliffs. I increased the exposure to brighten the sky and seafoam where the water has broken on the rocks. Increasing the saturation and temperature of the image allowed the creation of a warmer image, in turn emphasizing the greens, yellows and the orange tones in the image.

Increasing exposure, contrast, saturation, the temperature and shadows allowed for a more dynamic image to be produced. The final alterations of the photo make the cliff structure the main feature and detract the focus from the background, which had been the most prominent in the original image.

First steps in editing the image (not final levels)

Decreasing the temperature, increasing contrast and saturation, and increasing the highlights within this image allowed me to achieve the sublime effect I was aiming for.

Project Evaluation:

Looking into natural landscapes has allowed me explore the idea of romanticism in photography. It’s resulted in me thinking about what type of landscapes and what aspects of nature provide the most powerful effect on an individual. Stone structures such as cliffs and rocky areas stood out to me as a photographer due to their robustness and permanence, a characteristic that humans lack. These landscapes proved to be entirely humbling due to the power of the sublime.

Having grown up in Jersey, many of these places I visited had a nostalgic and sentimental value to me which made it a challenge to photograph purely through how the image looks through the viewfinder.

The photo-shoots also proved to be difficult due to the mass amount of interference caused by man-made structures and objects. Completely ignoring these structures limited the angles at which I wanted to take photos at. Using the manual settings on the camera was a new experience and faults in my produced images, such as camera shake and over-exposure, are prominent throughout my shoots due to lack of experience.

An uncontrollable factor that limited the days I could complete shoots was the weather. However, its mercurial nature also meant that I could photograph and capture different cloud formations within my images and the sky had also provided dark greys and blues which helped to dissect many images.

Final image:

Editing in the style of Ansel Adams:

Editing the image in photoshop allowed me to control which colours within the image were darker and vice versa. This allowed me to make a highly contrasted image, similar to one of those produced by Ansel Adams. Following Adams zone system helped during the editing process.

Lighter tones are present in the small clouds in the background and elements of the sky. The ripple effect in the water is also highlighted by these light tones. The rocky formations help to dissect the image, making the photo more engaging to the viewer. The darker tones of these structures allow them to become a main focus of the image. I purposely wanted these to stand out when I took the photo as it’s a primary feature of romanticism to make the individual (or viewer) feel inferior to nature.

The sand within the image provides a texture that differs from the rough surface of the rocks. The stream of water creates a sort of leading line, directing the viewer though the smoothness of the sand to the uneven and irregular surface to the rock formations, sustaining the contrast within the image.

HISTORY OF ROMANTICISM

Image result for A Storm in the Rocky Mountains, Mt. Rosalie

Between the late eighteenth and mid nineteenth century, an artistic and intellectual movement took place in Europe. Romanticism involved the portrayal of the beauty of nature, focusing on landscapes, weather phenomenons and dramatic colours.

A Storm in the Rocky Mountains, Mt. RosaliePainting by Albert Bierstadt

In the mid 18th century, romanticism in landscapes was portrayed through paintings. Artists like Albert Bierstadt, Frederic Church and Caspar David Friedrich are important figures in the Romantic movement, creating paintings that captured melodramatic scenery to initiate emotion, and a feeling of awe in the viewer.

Definitions/ Key terms

  1. Auto Focus – The camera will automatically focus the image after pressing the shutter half way.

2. Manual Focus – By twisting the front part of the lens, you can manually focus or blur certain areas of the image.

3.White Balance – The process of removing unrealistic colour casts, so that objects which appear white in person are rendered white inthe photo.

4. ISO – Measures the sensitivity of the image sensor.

5. Aperture – Refers to an adjustable opening in your camera lens that is able to limit the amount of light passing through the lens and hitting the camera sensor.

6. Focal Length – The focal length of the lens is the distance between the lens and the image sensor when the subject is in focus e.g the standard cameralens with a focal length of 18-55mm

7. Depth of Field – Depth of field is the distance between the closest and farthest objects in a photo that appears focused/ clear.

8. Slow / fast Shutter Speed – When taking photos of fast moving things such as a runner, a fast shutter speed will be used in order to capture them clearly. Whereas, a slower shutter speed allows the lens to record more light over a longer period of time. 

9. Exposure and exposure compensation – Exposure compensation is used to alter exposure from the value selected by the camera, making photographs brighter or darker. 
Exposure – The amount of light the camera/ lens allows to pass through.

10. Exposure bracketing – This is a technoque used by many photographers; where they will take multiple photos of the same thing, but change the exposure each time. So when editing the images can be combied to show both colour and textures/ objects/ shadows.

Photoshoot plan

What:

Romantic, landscape environments. Cliff faces, caves, woodlands, the sea and sand (beaches).

When:

Mornings, afternoons, leading into the evening – avoids harsh light from the middle of the day and allows for a different atmosphere and setting when the sun begins to set.

Where:

Possible locations:
Sorel point,
Grosnez,
Plémont Beach,
La Corbière,
Blanches Banques (sand dunes)

Why:

I’ve chosen to do this photoshoot with these locations to relate it back to the research and topic of Romanticism within landscape photographs we’ve been studying. I’ve chosen a variety of natural environments for my shoot in order to cover the different emotional responses that come from the power of nature and the sublime.

How:

Equipment:
– 2x Lens
– Tripod
Use of tripod to keep the camera static when using slower shutter speeds and to keep the camera view the same when exposure bracketing (to create hdr images).
Different lenses to have the optimum focal range and depth.

Image result for exposure bracketing
Example of exposure bracketing.

I’m aiming to purposely over-exposing and underexposing a group of images to build up layers for some hdr photos.
Checking the weather forecast (Wind strength, sunset, tides etc.) to work out the right locations for each condition.
– For example, when the wind is quite strong I might go to the cliffs or by the sea to photograph the effect of the waves on the coast.

Landscape Photography- Romanticism

Romanticism in Landscape photography is all about reflecting and showing the power of nature and the environment. The romantic movement began in late 18th to early 19th century. Romanticism was not about harmony, peace and balance but more about the emotions and sometimes even irrational emotions that the artists may have, or even their experiences.

In terms of Photography it is seemed to be unpredictable and uncontrollable, this type of photography is seen to be interpreted in various ways and formats; such as beautiful, quiet and sometimes sensual. but also ” dark, stormy, with a foreboding spirit

Due to the start of the Industrial revolution many people wanted to fight back which triggered the era of romanticism, this allowed photographers to focus on the power of nature and the places in the world that we still had “little human impact”.

Aperture & Depth of Field

Aperture:

Is the opening of the lens to see how much of the light will enter the camera sensor. If the camera is in a dark environment then the opening of camera will be largely opened; whereas if the camera is in an environment with light then the opening wont be as large as the dark environment. The amount in which the camera is opened is determined by the f-stops. Here in f/2.8 it is clear that a lot of light is entering the light sensor. On f/16 there is hardly any light entering the light sensor therefore this f stop is better made for a light and bright environment.

Our Photography

With these 3 pictures I instantly knew that they would not work due to people moving or the angle in which I took the image.

After Taking these pictures I unfortunately realized that most of the images were underexposed.

This was my favorite image as although the image is under exposed due to me using a shutter speed of around f/22 the image was clear you are able to see the light shining on the pens which I think creates a nice contrast.

Photo montages

1st Montage


Technical

  • Lighting – The back ground photo is taken in natural lighting but my own photos (the hands holding the poppies) were taken with flash. The colour of the poppies are slightly saturated to contrast with the black and white hands and the soldiers are over exposed.
  • Aperture -The majority of the photos in the montage are sharp except for the soldiers which have a grainier look due the opacity being lowered.
  • ISO – The texture of the gravestones are the most noticeable and the soldiers have a higher light sensitivity.

Visual

  • The majority of the colours in this montage are warm making the montage have positive connotations which juxtaposes the sadness of the thousands of gravestones. The tone of the montage is mostly lighter shades and the smooth texture of the sky contrasts with the rest of the photo making the most important things in the photo stand out e.g. the grave stones and the poppies. The repetition of the poppies and gravestones signify the importance of them. The space between the gravestones getting thinner the further you look into the photo gives the photo a 3D effect.

Contextual

  • The soldiers faded look is to make them look more ghost like and to remind you that the graves are meant to represent actual soldiers who fought in the war.
  • The poppies have been duplicated to show a high level of respect for the soldiers and to intensify that respect the saturation has been put up higher to make them stand out even more against the white gravestones.

Conceptual

  • The overall idea of this montage was to remind people too pay their respect to the soldiers as we wouldn’t have liberated without them fighting.

Ansel Adams case study

Ansel Adams was recognised for his monochromatic landscape photos. He formulated a zone system, from which he attempted to encapsulate each of the 11 zones into his photography.

Image result for ansel adams zone system
Example of how the zone system is applied (Not one of Adams’ photographs)

Adams grew up and was tutored at home. The lack of interaction with others may have led to his interest in nature. He became an environmentalist, meaning he was passionate about protecting the wildlife and the natural environment. He aimed to encourage the conservation of nature and the wilderness through the use of his camera and the photographs he produced, allowing people to see the sublime power of nature.

Adams techniques

For his work, Adams used numerous different colour filters in order to achieve the tonal effect he was aiming for. He also spent a lot of time in the darkroom to develop a singular image, painting onto the enlarger the areas of the photo he thought should be darker or lighter than others- A method otherwise known as dodging and burning that he used to cover all aspects of his zone system.

Photo analysis

Monolith, The Face of Half Dome, Ansel Adams.

The composition of Adams’ image creates an atmospheric perspective. Having a small cliff edge in the foreground (and in the bottom third) aids in the sublime portrayal of the cliff face behind as it places the spectator where Adams would’ve taken the photo and highlights how the cliff face towers over everything in the image. It’s the only thing present in the top two thirds, illustrating how colossal the cliff face is.

The prolonged exposure on his camera allowed for Adams to produce highly contrasted images. This particular photo covers all 11 zones of his own developed zone system, with the darkest areas being a main focus in the center of the image. The light intensity is low at the top of the image (the sky), which makes the image quite dramatic as dark skies are unnerving and usually associated with storms and discomfort.

The lack of colour in his tonal imagery allows the spectator to focus on individual shapes and formations in the cliffs within the photo. If the image was in colour, the greens of the trees would divert the attention from the cliff face, in turn affecting the overall powerful aspects of his image.

Being an environmentalist, Adams wanted to preserve the beauty of nature in his photographs and advocated the protection of natural environments and landscapes. By producing images like this that are striking helps him to convey the sublimity of nature to the spectator.
