Tonal contrast is a significant factor to be aware of when editing the photos for the website. Colours with short wavelengths for example blue are hard for older people to identify.
As we mature into old age our eye’s lens tends to “yellow” and our pupil size shrinks which results in colours looking dimmer and slightly brownish. Also, most of our lives we see colour before form but mature eyes begin to see form before colour (although creatives often continue to see colour first).
To help my identify if my images during editing has a good tonal contrast, I will need to turn the image in to black and white then make adjustments to ensure elderly people find them easy to view.
