Category Descriptions (Beta)


Category Descriptions
The following may be used as a broad guideline to the categories:

Pictorial (pc)
Pictorial entries include all the subject material, which is not already defined for other categories for e.g.
nature, photo travel, etc.
Digital manipulation is allowed, provided the end result “looks natural”.

Nature (nt)
A nature image is restricted to the use of the photographic process to depict observations from all branches
of natural history in such a fashion that a well-informed person will be able to identify the subject material
and to certify to its honest presentation. This includes aspects of botany, geology, insects, fauna and flora,
but excludes Anthropology and Archaeology.
Human elements shall not be present unless, on the rare occasion where human elements enhance the story
but must be unobtrusive. For this reason, animals shown to be in captivity or domestic animals are not
accepted.
Photographs of artificially produced hybrid plants or animals, mounted specimens, obviously set
arrangements, derivations, or any form of photographic manipulation that alters the truth of the
photographic statements are ineligible.
Digital manipulation is not allowed.

Photojournalism (pj)
Photojournalism entries shall consist or story telling pictures or sequences such as are seen in the news
media, including human interest, documentary and sport news. The images capture events in the
photographer’s time, be they of national importance or local neighbourhood pictures.
These images have one thing in common – they must be informative and have emotional impact, usually with
human interest. The journalistic value of the image will be considered more than the pictorial quality.
Images may not misrepresent the truth and therefore, digital manipulation is not allowed.

Portraiture (pr)
A portrait arrests our gaze for what it reveals. However, fleeting the moment, the photographer must
connect with the subject and extend the connection to the audience. Subjects include people, animals,
insects etc. The image may be head and shoulders or full figure, but must depict the subject’s character or
emotion at that moment. Animal portraits are usually only of the neck and head.
Digital manipulation is allowed.

Contemporary/Altered Reality (ar)
This category stands apart from the other categories as a form of art and may be defined as a concept which
stimulates the mind of the viewer to interpret the message conveyed through the creative uses of line, form
and colour.
This definition specifically includes computer generated / manipulated images and covers technique,
experimental work or contemporary work. The final result does not have to bear any relation to the original
image since reality may be altered.
Digital manipulation is allowed.

Landscapes (ls)
Images covering landscape scenes of land, sea, cloud and cityscapes may be entered in this section.
Depictions of these scenes may include human elements or domestic animals.
Only images that do not alter the truth of the photographic statement will be eligible.
Digital manipulation is not allowed.

Still Life (sl)
Inanimate objects pictorially arranged.
Digital manipulation is allowed.

Photo travel (pt)
Subject matter must portray photo travel. A photo travel entry should capture the feeling of a time and place,
and portrays a land, its people, and its culture in its natural state. Ultra close-ups that lose the identity, model
shots or manipulated images do not qualify. Entries should not be limited to geographical areas and may
include, but are not limited to other lands or countries and may include those of domestic origin. The key
differentiation between Photo Travel and other forms of photography is the portrayal of Culture.
Digital manipulation is not allowed.

Black & White (bw)
A monochrome image is an image consisting of a single colour or shades of that single colour against a neutral background.
All black and white images are monochrome images, but not all monochrome images are black and white.
For example, a monochrome image might consist of black on yellow.
Gray scale is a method of representing black and white images on a computer.
Gray scale images are represented using only 256 shades of Gray rather than the full pallet of colours.
Digital manipulation is allowed.

Post capture processing and ethics (Beta)

Post capture processing and ethics (Including more on Category Descriptions )

In view of the perceived perception by some that digital photography is synonymous to digital manipulations, it
is essential to address the ethics and “rules” of digital manipulations within the various divisions. While the
aspect of manipulation or alteration of the “truth” of a photo is by no means unique to a digital image, it is a fact
that the digital process allows much greater possibilities with regard to the alteration of the original image.

It is suggested that the “rules” regarding permissible post-processing of digital images be clearly stated and then
to leave it to the photographer and his/her own integrity and conscience to abide by the rules. This is suggested
since it is felt that there are very few practical measures that can be applied to verify whether an image was
changed enough from the “truth of the original scene” to be classified as “altered” or “manipulated”.

Imposing laborious measures to verify the authenticity of an image is likely to be flawed and might in the end
only serve to discourage participants. To add to the complexity of this issue is the fact that it is very difficult to
even try and define “altered” or “manipulated”.

For the sake of practicality, the following post-capture processing procedures performed on a digital image with
the aid of a computer and a digital image editing software package like Adobe Photoshop, within limits, will not
be considered as digital manipulation:

  • Adjustment / correction of the colour balance (especially relevant to scanned images).
  • Removal of dust and scratch marks on scanned images or spots from dust particles on the CCD / CMOS
    sensors of digital cameras.
  • Adjustment of exposure and contrast, including dodging and burning similar to those techniques that are
    commonly used in traditional printmaking.
  • Adjustment of colour saturation.
  • Sharpening.
  • Image Cropping and Horizontal Rotation.
  • Image Resizing.

Judges realise that some of the above adjustments (e.g. changing the colour balance) can be used in such a way
as to create an unnatural / manipulated look, hence the cautionary reference to “within limits”. However, the
permissible range of use of the above will be almost impossible to quantify and it is thus left to the discretion of
the photographer.

No additional alterations should be done to images intended for entering in the following divisions:

  • All nature divisions including zoological and botanical/geological sub-divisions.
  • Photo journalism divisions.
  • Photo travel divisions.

As stipulated by the rules applicable to the various other divisions, additional digital alterations will be
permissible to images entered in other sections like the open or pictorial sections. It is further assumed that the
digital image will be original and does not incorporate elements produced by anyone else but the photographer.
No copying of any kind of somebody else’s work is permissible.

AV Information

Audio Visual

AV short for Audio Visual, is another way to display images. This method is made up of a number of images shown individually with creative representations in displaying the images and in the transfer between images and accompanied by music which enhances the creative experience. 

PSSA Definition of Audio Visual:

An Audio Visual (AV) is a compilation of still images, which may include movie/video clips, with an integrated theme or story line where audio, transitions and images are interdependent. An effective sequence will therefore have unity of the various elements, i.e.: the conception, the visuals, the audio, communication and technique. Artistic expression within it can take many forms and is only limited by the author’s imagination and creativity.

AV recommendations

  • AV to be no longer than 5 minutes. (3 minutes 12 seconds official accepted length)
  • Video or third party images not to be more than 20% of the total AV playing time.
  • Size to be no larger than: 1920px wide and 1200px high. (AVs normally 16:9, 1920 x 1080)
  • Resolution to be 70 dpi.
  • Format: exe, mp4 (avi and mov accepted)
