What I want to do is setup the camera in MANUAL MODE. When I take the picture, I want it displayed on the LCD along with the black and white HISTOGRAM(not RGB). I then want to adjust both the shutter speed and the f stop on that same screen . I know I can go to the OVERVIEW and that will display the histogram, where I can adjust the shutter speed and f stop, but then I have to take another picture to see the results. I am quite sure it can be done. I think I had it one time, but forgot how I did it. In other words, take a picture, see the image on the display with the histogram, adjust with the command dial.
