I’ve heard this question over and over again…”What is a histogram?” or “How do I know I’m exposing right in camera?”
If you already know what a histogram is, this video is not going to be helpful to you at all, this is an OVERVIEW on histograms.
But! If you struggle with exposure, if you struggle with making sure you know you have the right exposure in camera on location or whatever else, this is going to be super super helpful to you.
This is my secret weapon when it comes to really knowing quickly whether I’ve done a good job with exposure or not.
Take a look at this histogram over here! It’s basically just a graph of how many brights we have (over on the right side), how many darks we have, or how many mids we have. So it’s just a graph of dark on the left side, bright (or white) on the right side, and then mids in the middle! It’s just going from dark going all the way to bright, and it’s giving us mountains of information — the black mountain is going to show up higher if there’s MORE of THAT in the image.
So this guy over here, there’s a ton of this, ton of that, not much of this, but then we have a good amount of mids or upper mids here, and then as we go all the way down, there’s a little peak near the shadows, so the HIGHER up we go here, shows up how MUCH we have, and as we go left/right, we’re going from dark to bright. Are you more comfortable with the answer to the question, “What Is A Histogram?” now?? Here’s a bit more info:
Take a look at this image, real quick I’m going to draw a rectangle around this area. So in your mind, is this area dark or bright? Boom, right away, super bright. There’s nothing else here, it’s just pegged bright here. But! Let me pull it down to the grass, and we have mids, or upper mids here. Take a look at that. Now if I pull the rectangle over his SUIT, look at all those darks! So as I’m highlighting this area, this histogram is only showing me the data for the box that I’m highlighting right here. So WITHIN THIS BOX, what it’s telling me, is there’s a BUNCH of DARKS and there’s not much of anything else.
As I put the box over the grass, it shows me there’s a bunch of mids and there’s no brights and there’s no shadows. As I pull it over the sky here, it shows me that I have a bunch of brights and nothing else.
So that’s a quick overview, hope that was helpful! Watch the next video here.
