Re: Google lightens the image to reduce detail
There is no conspiracy, honest. ;-)
The difference between Google & Bing is solely down to their respective dataset provider's useable coverage, (Bing having paid for exclusive rights to the best current available, possibly 25cm/px).
The area you refer to, has fairly reasonable oblique coverage, (AIUI, Bing's rendering engine can re-project oblique to vertical), but poor vertical coverage, (AIUI, required by Google Map's rendering engine).
If you look in Google Earth, their source for that specific SW trending NE coastal zone, is probably 1m/px, and very badly affected by haze, (possibly oversampled, hence the funny water colour/pixellations).
GetMapping have been struggling since 1999, with aircraft availability, against weather conditions, (cloud cover & haze), to collate a coherent set of commercial quality vertical imagery for Scotland, (30cm/px or better).
Their primary targets being commercially viable areas, i.e. densely populated, (where 6cm/px is getting to be the expected norm), but NW Scotland ticks few commercial boxes.
Until fairly recently, their website's coverage maps displayed for each available resolution. For Scotland, these clearly showed as extremely stripey, (particularly so in NW, and Peterhead, areas). Since processing their 2008/9's aquisition campaigns, they've rationalised these into a single coverage map, which looks almost presentable.
