Processing

This mainly needed "cropping", "levels" and "curves" to to improve the tonal range, and "colour balance" and "hue and saturation" to improve the colour balance. Some scanner colour management issues were mitigated using "hue and saturation" to desaturate certain cyan.

Then the web version was sharpened using "unsharp mask". The parameters were: amount: 100%; radius: 0.4 for the 700-pixel version, 0.3 for the 500-pixel version; threshold 0 + (for the rear elephant) 80; 0.4 or 0.3; 0.

Main Photoshop 6 and ImageReady 3 features used

• Image size - crop, image & canvas size.
  Image adjustment - levels, curves, variations, colour balance, hue/saturation, clone tool.
  Image adjustment using adjustment layers.
  For the web version only - "unsharp mask" managed in layers created for the purpose.
  Presentation features: automate > fit image, then ImageReady was used to evaluate compression and save as JPEG.

Typical Photoshop 6 features not used

• Layers (except adjustment layers, and unsharp mask layers for the web version). Filters (except "unsharp mask"). Over 90% of the tools.
