[QUOTE="Bourbon Neat, post: 457124, member: 37727"] Inquiring minds would like to know stuff. Answer if you are able and comment if ya like. Firstly is this statement close to accurate? The histogram shows the amounts of digital information in the image and which areas have more or less of the information. I have been underexposing to avoid blowing out the highlights. In very good lighting this has worked well but in less than favorable lighting the results are like turd at the dark end. Very noisy at the dark end, beyond repair kind of noisy at times. Zooming into the dark end on a "peaks to the left" image easily shows the noise. . . . Zooming into the highlights on a "peaks to the right" image does not show much noise at all. Is this a correct statement? Noise in a digital image is not part of the scene captured. Does the histogram peaks to the left include the additional information of the noise, making the peak taller there? If so, is their less digital information in shadows than there is in highlights? Is there more digital information in the highlights, thus preventing the noise to infiltrate? Is there correlation of dynamic range and the histogram we see in lightroom? Now I am even dizzier from composing this. [/QUOTE]
