E-Photography - PSSA Standards and Guidelines
Sandton Photographic Society follows the PSSA guidelines for e-photography. The guidelines are summarized in this document, but if you want more information please download "E-Photography – PSSA standards and guidelines" from www.pssa.co.za Digital photography is new to many of us, so please feel free to speak to other members of the e-photography section if you want to know more.
1. Club judging
Here are the “rules” regarding permissible post-processing of digital images. Since there are very few practical measures that can be applied to verify whether an image was changed, it is left to the photographer and his own integrity and conscience to abide by the rules.
To educate the club, judges should point out when the rules might have been violated, but the photographer should only be marked down if it is without a doubt.

Need a software program to keep your images organised? Take a look at Picasa it's all you need, just visit the Picasa download site. The program is FREE !
The following manipulations are permissible in all categories.
Permissible Processing
- Adjustment of color balance.
- Removal of dust and scratches.
- 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.
- Cropping and resizing.
The image must be original and may not incorporate elements produced by anyone but the photographer.
Restricted
Only permissible processing is allowed. Items may not be added or removed from the picture. The image should not misrepresent reality.
Pictorial
Items may be added or removed for pictorial effect. The image should still look natural.
Altered reality
The image can be manipulated to create an unnatural/manipulated look.
2. Working with Digital Images
It is important to have your computer monitor properly calibrated and to have your images stored in the appropriate “colour space”. This will ensure that when the images are displayed at the club they look the same as they do on your own computer.
Calibrating the Monitor
A good quality CRT (cathode-ray tube) monitor gives better results than a LCD (liquid crystal display) monitor.
If you have Photoshop run ‘Adobe Gamma’ (for Windows users this is accessed from the Control Panel). Follow the instructions. When requested select a gamma of 2.2 (or 1.8 for a MAC) and a white point of 6500. There are other software and hardware packages that can also be used to calibrate the monitor.
Colour Space
- Find out what colour space your digital camera (or scanner) uses. Most cameras use sRGB. Read the manual, or use Photoshop’s ‘Image/Mode/Convert to Profile’ command to see the colour space of the image after it has been downloaded to the computer.
- Images must to be converted to sRGB before submitting to the club.
- If your camera can capture images in Adobe RGB or raw format, you might want to use one of these formats. They can capture a wider range of colours, which can be manipulated before converting to sRGB. Opinions differ on this matter. Some experienced photographers find that it makes little difference and capture their images directly in sRGB to save the conversion step. You should experiment to decide whether the use of these wider colour spaces improves the quality of your images.
Submitting images to the club.
- Save with a maximum pixel resolution of 1024x768 pixels (in Photoshop use Image/Image Size and tick Resample Image to change the number of pixels). View the image at 100% after resizing (View/Actual Pixels or Ctrl-Alt-0) to ensure that it is satisfactory.
- Use the sRGB colour space (in Photoshop use ‘Image/Mode/Convert to Profile’ to change the colour space)
- Save as JPEG using a high quality compression setting (the saved image should not be bigger than 1 Megabyte)
- Name the file as follows: Star_cat_Title_Author.jpg
s star rating (1-5)
ccc first three letters of category in lower case (e.g. spo=Sport) One and two star workers should use "pic" as the category
ttttt title (max 24 characters)
Name Surname (no underscore between your Name and Surname, use Caps and spaces)
For example 3_pic_Setting Sun_Joe Smith.jpg. - For one and two star photographers, pictures are judged according to their pictorial quality rather than according to criteria for categories such a Sport etc. When naming images please use pic as the category.
- E-mail to sandtonphoto@bryanston.com (or give to Lyneth on a memory stick/CD) at least two days before the club meeting.
- You may submit up to three digital images per night. There is also a limit of at most six images in all three media (slide/print/digital) excluding images for the set subject competition. The images may not be similar to images submitted in the other media.
