I read about this technique to use the histogram and overexpose intentionally without clipping the highlights, always in raw to obtain better pictures specially less noisie in the shadows.
In a recent travel to Cuzco I take this picture from the plane (some inevitable scratchs in the windows plane), as you see is overexposed. The picture was taked with a canon xs, with canon 18-55 mm, in 27 mm, iso 100, f8, 1/60 sec, with +2 ev in exposure compensation, with aperture priority in raw format
The histogram shows exposure to the right.
After developing in camera raw, you have this picture
A crop of 300% of a shadow area doesn´t shows noise, I haven´t reduce noise with software.
I will love to hear your experiences about this technique
Thanks in advance. MArio
