different depth of field examples

here is a example of the depth of fields at F5.6, F22 and F11

Depth of Field

In optics, particularly as it relates to film and photography, depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.

In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background. In cinematography, a large DOF is often called deep focus, and a small DOF is often called shallow focus.

Jane Bown

Bown works primarily in black-and-white, using available light, and a forty-year-old film camera. She has photographed hundreds of subjects, including Margaret Thatcher and John Lennon. She also took Queen Elizabeth II's eightieth birthday portrait.

Bown's extensive photojournalism output includes series on Hop Pickers, Greenham Common evictions, Butlin's holiday resort, the British Seaside, and in 2002, Glastonbury festival. Her social documentary and photo journalism was mostly unseen before the release of her book Unknown Bown 1947-1967 in 2007.

In 2007 her work on the Greenham Common evictions was selected by Val Williams and Susa

 Bright as part of How We Are: Photographing Britain, the first major survey of photography to be held at Tate Britain.In 2007 her work on the Greenham Common evictions was selected by Val Williams and Susan Bright as part of How We Are: Photographing Britain, the first major survey of photography to be held at Tate Britain. Bown was awarded an Honorary Fellowship of the Royal Photographic Society in 2000. These are awarded to distinguished persons having, from their position or attainments, an intimate connection with the science or fine art of photography or the application thereof. In 2014, directors Luke Dodd and Michael Whyte released a documentary about Bown, Looking For Light, featuring conversations with Bown about her life and interviews with those she photographed and worked with, including Edna O'Brien, Lynn Barber and Richard Ashcroft.

What was the intention? What is the reason(s) why the photographer made the photograph? What's the subject? In my opinion Jane Bown made her photo's how they are so there isn't anything in the background to take the attention away from the person's face.Which of these best describes your photograph? I think it's a good example of expressive photography and made to show the persons emotions.

WHAT IS THE COMPOSITION? (This is the arrangement or structure of the formal elements that make up an image, such as ‘Rule of Thirds’).

1.How is the photograph framed? How has the photographer arranged the object(s) or people within the boundaries of the photograph?

The person’s face in the centre of the photo.

2.What is the setting? Is it actual physical surroundings or scenery? Is it artificial like a photographer’s studio?

Nothing so you don’t get drawn away from their face.

3.What is the vantage point? (This is the place from which a photographer takes a photograph)Was the vantage point from eye level, low down or high up? Was the vantage point from which the photograph was taken unusual or exaggerated?

Eye level.

4.What is the balance? (The distribution of objects or people in a photograph.

Symmetrical balance distributes objects and/or people evenly in an image. Asymmetrical balance is found when objects or people are not evenly distributed in an image).Symetrical balance.

WHAT IS THE FOCUS? What areas appear clearest or sharpest in the photograph? What is not?

Central focus is the object(s), which appears most prominently and/or most clearly focused in a photograph.

Background: the part of a scene or picture that is or seems to be toward the back. Is this in focus or out of focus? Is this because of Depth of Field?The persons face.

HOW DOES THE LIGHT APPEAR IN THE PHOTOGRAPH? What areas of the photograph are most highlighted? Are there any shadows?Does the photograph allow you to guess the time of day?Is the light: natural or artificial, harsh or soft, reflected or direct?Contrast: are there strong visual differences between light and dark, textures and objects?Their face and the light is artificial.

FIFTH QUESTIONS: CHOOSE WHICH QUESTIONS ARE APPROPRIATE TO YOUR PHOTOGRAPH.1.LINE: are there objects in the photograph that act as lines? Are they straight, curvy, thin or thick? Do the lines create direction in the photograph? Do they outline? Do the lines show movement or energy? A ‘Contour’ is the outline of an object or shape.  The light outlines the persons chest and face.

6.VALUE: is there a range of tones from dark to light? Where is the darkest value? Where is the lightest? The lightest areas is his face so the viewer doesn’t get distracted by the background.Light centre dark edges.

High key lighting studio

High key photography uses unnaturally bright lighting to blow out most or all harsh shadows in an image. High key methods were originally developed as a solution to screens that couldn't properly display high contrast ratios, but has developed into more of a stylistic choice.

What is Shutter speed

Shutter speed is ‘the amount of time that the shutter is open’.

In film photography it was the length of time that the film was exposed to the scene you’re photographing and similarly in digital photography shutter speed is the length of time that your image sensor ‘sees’ the scene you’re attempting to capture.

What is ISO

In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography – the lower the number the less sensitive your camera is to light and the finer the grain.Higher ISO settings are generally used in darker situations to get faster shutter speeds. For example an indoor sports event when you want to freeze the action in lower light. However the higher the ISO you choose the noisier shots you will get. I’ll illustrate this below with two enlargements of shots that I just took – the one on the left is taken at 100 ISO and the one of the right at 3200 ISO (click to enlarge to see the full effect).

What is aperture

Aperture is one of the three pillars of photography, the other two being ISO and shutter speed. Without a doubt, it is the most talked about subject, because aperture either adds a dimension to a photograph by blurring the background, or magically brings everything in focus. In this article, I will try to explain everything I know about aperture in very simple language.
