Whilst using my Sony A300, I found that in high light contrast scenes, I would have to use a -1 or -2 EV exposure compensation to stand a chance of not blowing out detail in the highlights. Since using the A99, I have found that the camera copes extremely well with high light contrast scenes without the need for any exposure compensation at all. That said, if the contrast is really that extreme, the camera might - and I stress 'might', because I have not had such a situation occur as yet - require a -0.5 or -0.66 exposure compensation. But this would have to be a very extreme case of contrast indeed. The dynamic range of the A99 is so much greater that it copes very well with extreme lighting conditions. I'm also starting to find that the RAW output requires less alterations in PP than the output I got with my A300. In fact, the A99 is putting forward a very good case for using jpegs straight from the camera without any need PP at all. I mean separate editing software when I say 'PP' as opposed to in camera PP. That said, I could not as yet get away from minimal tweaking in PP as I still get enhancements in IQ by using RAW and PP software.
