You can certainly go the route of auto-white balance but it's only one route. I think it's much more interesting to see how different people stress different things in contemporary photographs. Some are clearly using lens correction, some are pushing the clarity way up, or the blacks way up- or both - for that ultra-crisp, surreal look. And some are using custom presets made by themselves or downloaded from other sites, for looks resembling classic film stocks of the past. I'm just grateful we're not all using the same strategies - I appreciate a healthy mix of styles as opposed to the tyranny of any one single trend.
