what I have been really dreaming about is that I can set one or two of the three (Av ,Tv and ISO), and also set the range of each parameter and let the camera do the rest, this is the first dream. second dream, it is better if I can set or program the priority of these three parameter, e.g. when I shoot bird in changing lighting condition, The priority of these parameters is like this


I set f5.6, Tv range1/800-1/6400), ISO(100-800), sun setting


1) f5.6 1/3200, ISO 100, and when it gets darker, I would go


2)f5.6 1/3200,ISO 200 and when the lighting gets even darker, instead of rise ISO to 400(if you use Auto ISO), I prefer


3) f5.6 1/1600,ISO 200 and then when it's darker, go


4)f5.6 1/1600,ISO 400.......


5)f5.6 1/800,ISO400....


6) f5.6 1/800, ISO800.


and finally the dream is that the camera will always automatically correct the exposure to perfect if you shoot in raw


I think camera can check the histogram after we press the shutter half way and correct it to perfect before we click it all the way down to take the pictures
