Camera Raw Histogram: How To Accurately Edit & Process Images

https://www.shutterbuggs.com/ - In this video, I’d like to talk about the importance the histogram plays when editing your photos. So, as you can see, I’ve opened up an unedited image of a beautiful swan. Now, it’s basically got all the defaults given to it by Camera Raw by itself. I haven’t made any actual adjustments whatsoever. It was shot at F11 at one 2/50 of a second at ISO 400. And as you can see, here are the current distributions of values across the histogram. Now, the histogram itself is basically a graphical representation of the data, or information that is distributed across your entire photograph. Now, the main importance that the histogram plays for you in editing your photographs is it will tell you whether or not you have blown out your highlights or clip your shadows, which is quite important and especially important in this particular shot where I’ve got some very distinct highlights in the swan’s feathers. Now, as you can see in the histogram, you’ve got a range of different colors that are displayed and presented to you. The histogram itself displays additive and subtractive colors-additive being red, green, and blue; and subtractive being cyan, magenta, and yellow. The histogram also displays luminance values, which is essentially all the colors combined into one value that is called luminance, or brightness for some of those out there, and it’s actually displayed in the histogram as white, as you can clearly see just here. You’ll also notice in the top left-hand and top right-hand corner of the histogram, there are two arrows. Each one of these is basically clipping warnings. So, the histogram itself goes from shadows, on the left-hand side, right the way through to highlights on the right. So, on the left-hand top corner, you’ve got the Shadows Clipping Warning, which we’re going to click on, and turn that on. And what you’ll notice is in the shadows just above the bill of the swan, is that all of this blue has just come in. And that’s showing you that the shadows are actually being clipped, especially in the blue area. Now, if we go across, and turn on the Highlight Clipping Warning, you’ll notice that the highlights in the feathers, particularly in the reds, have been blown out. So, what you want to do with this type of clipping information is make your adjustments so that you actually avoid blowing out, or clipping, your shadows or highlights. So, what I would do is make your settings, playing with your sliders, and adjusting them so the actual highlight information is not clipped, like so. And if we go to the blacks, we can reduce the black import here. And you’ll notice that actually removes the highlighted blue for the clipping of the shadows. There is also another way to look at this information that is actually a bit more simplified, and a bit easier to distinguish, as opposed to viewing the clipping information directly over your image, with all the other color information that you’d actually have present. And to do that, we’ll jump back to Default as those values are blown out. And if we hold down Alt on a PC, or the Option key on a Mac, and do the same thing that I did before by dragging the exposure slider, you’ll notice that the screen has gone black, and it’s now displaying all the areas on the image that are actually blown out in the highlights. And as we slowly adjust the slider in the opposite direction, you’ll notice that they’ll actually disappear. And what you want to do is you want to get to the point where just they disappear without going too far past that point. Now, we can do the same also for the shadows. If we jump down to black, and hold down the Alt key or Option key once again, you’ll notice that the screen is actually white, and it’s actually displaying the shadows that are clipped in your image. So, once again, if we just reduce the black value you’ll notice that these will slightly decrease in the amount of areas that are actually clipped in your shot. So, hopefully that gives you a reasonable overview of how you can use the histogram when editing your raw files. Now, please take into account that the histogram is a starting point, and a guide when editing your photos. I mean, sometimes you may have a perfect histogram, but your photo may not be punchy enough, or may not stand out off the canvas enough, or it may not be what you originally visualized. So, what you sometimes need to do is make a compromise between the histogram and your image in order to get what you want. But, at least you have that starting point, and that guide, to help you along the way. For more information visit us online at https://www.shutterbuggs.com/
