This is the colorspace that your camera uses, and the one that Photoshop defaults to. The RGB colorspace is the standard used in digital photography. Click again to see the eyeball with your changes to the image. When the eyeball disappears, you will see your picture before the adjustments you just made. For the curves adjustment layer you just created, click on the eyeball. On the right side of your screen where your layer is shown, you will see a little eyeball just to the left of each layer. Now it is time to see the “before” and “after” pictures of your image this is one of the benefits of working with layers. Again, input values of about 90 should get you roughly where you want to be. Now, grab the right endpoint and pull it to the left the exact same amount that you moved the left endpoint to the right. Your picture just turned a shade of blue but don’t worry about it. So grab the left (black) endpoint and drag it toward the middle a little bit. Click on that and now select the “B” channel.Īs you did above, just scoot in your endpoints toward the middle of the histogram. So, go back to the drop-down that currently reads “A” channel.
What you are going to do here is exactly what you just did in the step above, but this time you are going to do it in the B channel. Let’s go on and perform the second part of the LAB move. But don’t worry too much about what your picture looks like right now. You can use the Input numbers below to make sure you are moving each side in the same amount. In fact, pull it to the left the exact same amount that you moved the left endpoint to the right. Now, grab the right (white) endpoint and pull it to the left. Your picture probably just turned an ugly shade of green but don’t worry about it. There is no set amount to move it, but if you are looking for a little guidance drag it until the Input number reads -90. What you are going to do is grab the left (black) endpoint and drag it toward the middle of the histogram a little bit. Don’t worry about that – that’s the way most histograms look in LAB color. Most likely, it now looks like a big spike in the middle. You will immediately notice that your histogram changes dramatically. You will see a drop-down menu near the top of your adjustment layer and the current selection will be “Lightness.” Click on it and you will see three choices: the Lightness (or L) channel, the A channel, and the B channel.
You have converted to the LAB colorspace and created an an adjustment layer to work on. Scoot in the Endpoints of the A ChannelĮverything so far has been mere prelude to get you to this point, and you haven’t actually changed your picture at all yet. There are a few ways to do this, but if you don’t already have your own way, just click on “Layer” in the top menu, then choose “New Adjustment Layer,” then “ Curves.” Click “OK” in the box that pops up.ģ. Next, you will need to create a curves adjustment layer. All you have done is changed the way Photoshop renders color in your image (more about this later). From the drop-down, choose “LAB color.” That’s all there is to it.įor now, your picture looks exactly the same. To do that, just click “Edit” on the top menu, then choose “Convert to Profile.” When you do so, a dialogue-box will pop up. Convert to LAB Colorspaceįirst, you have to convert your picture to the LAB color space. So let’s walk through the steps of “the move.” There are five steps in this process, all of which are simple and can be accomplished in 30 seconds or less. That way, if you want to apply this move to your photos in a more nuanced fashion later it will help you to do so. Second, after walking you through the steps, you will see how this move works. You can follow these steps without even understanding how any of this works and it will work just fine for you. First, you will learn the five simple steps to achieve color separation using the LAB color move. In this article, you will learn two things. The right side of the picture is the same except for a curves adjustment layer done in the LAB color space.
The left side of the picture is an unadjusted Raw file.
