Next Club Evening
 
Date:        27 August 2018
Time:         18:45          

Set Subject: Contrasts - Mono = (Manipulation = Yes)

Dear NPC Member

We have already announced the club's change to full HD club entries.

This mail serves as a reminder and/or notification to all members that all Photovault entries from this month (November) will be in 1920 x 1080 pixel format. The following implications are relevant: 

  • Max file size is now 2MB  (not 500kB as previously)
  • When the old format files are submitted, they will be  projected much smaller on the screen and judges will possibly penalize you
  • The current 1024x768 format photos can not readily be up-sized to 1920x1080... you will be 'stretching' pixels and loose quality 
  • You will need to resize your photos from the original jpg or RAW file to 1920x1080 pixel size.

DESCRIPTION:

 Contrast is the difference between the blacks and the whites. High contrast means the blacks are really dark and the whites are really bright. Typically something that is low contrast looks like it has a grey wash to it. The blacks are more like a dark grey, and the whites a light grey. An image with high contrast will exhibit a full range of tones from black to white, with dark shadows and bright highlights. If you shoot in bright sunlight, you'll produce images with high contrast. Typically, high contrast images will enjoy strong, bold colours and textures will be emphasized. You might think of them as being deep and interesting. A mono image also has the colour removed, similar to Black and White photos, but… it may not display shades of grey, which is a requirement to be a black and white image. A mono image could be shades of yellow/red (also known as a sepia) or blue (which in the days of the darkroom was induced through the use of a chemical). So… a mono image consists of tones (shades) of something (red, yellow, green, blue, etc.) - not necessarily grey.
