Whooah there! Too much complicated stuff going down in this thread.

The problem is simple: over-exposed whites.

The answer is equally simple: expose the picture a bit less. Do it any way you like. Exposure compensation in any of the semi-auto modes (aperture priority, shutter priority, or auto-ISO) or just drop it a click or two in full manual. Any way you like and that is familiar to you.

You know that bright whites are going to need a bit of compensation and you can do that before you even squeeze the shutter, but always, always chimp to check your histogram and adjust further as required.
