This is where things get fun. We’ve just made an anchor point for the darkest and lightest parts of our image, Let’s get a little crazy with everything in between. Use the dropper tool to pick any portion of the image you’d like to adjust (or, since we’re being playful, just grab any point on the line) and make an adjustment. If you like it, leave it. If you don’t like it, slide it back into place. Feel free to tug and pull the curve as you see fit to create the image you’re looking for. After a moment or two of playing this is what we came up with:
The values for that particular tone as well as the entire curve have been changed. The previously slightly gray cup is now shockingly white and the highlights on the chrome of the espresso machine are much brighter (as is the rest of the image). There are some nice subtle changes to the image, such as in the reflections, and the shape of the Bakelite handle of the espresso portafilter is significantly better defined against the background now. It’s not a bad looking little image, and it’s a lot more visually interesting now than it was before.
What if we went the opposite route, though? What if we dropped the value way down instead of spiking it way up?
For example, in the last image of the previous section of the tutorial, we arrived at a pretty high-contrast image. The whites and highlights were fairly bright and the shadows were quite rich. Since we’ve established that we like high contrast images, the next time we go to use the Curves tool, we can pre-seed our image curve by selecting “Strong Contrast”. Let’s look at the curve it gives us for that preset:

We recommend manually playing with the Curves tool for a while until you get a real sense of how changing the curve changes your images. Once you’ve done that, however, you’ll likely find it invaluable to call on the Curve tool presets.
Now that we’ve looked at manual curve adjustments, let’s look at the Curve presets.
If you’re new to reverse engineering modern digital camera photos into black and white ones, we would suggest checking out previous tutorial, How to Convert Your Color Photos to Stunning Black and White Prints, first. In the introduction to that tutorial, we cover the over-arching motives for using advanced photo editing techniques to create great black and white prints.
Let’s see what happens when we add more points to the curve. Go ahead and repeat the process we performed above to select one the lightest points in your photo (like our espresso cup) and then pick darkest point using the same technique. You’ll end up with a dot for the light and a dot for the dark on your curve.
Unlike Levels, where the adjustments you make are applied uniformly across the image, the Curves are applied more granularly, which makes it much easier for you, the editor, to make very subtle changes to the image. If you want deeper shadows, brighter whites, or to isolate a particular shade of blue (now gray) in the sky framed in your photo, for example, you can do so with the Curves tool.
We couldn’t drop it all the way down because that would turn the picture almost completely black. Instead, we dropped it significantly below the starting line (the light gray line indicating the original baseline curve). You can see how it significantly darkens the photo and turns what was a bright coffee shop photo into something moodier. Clearly, the end result is a bit on the underexposed side, but we wanted you to see how dramatically a fairly small adjustment in the curve could change things.
The opening of the Empire State Building coincided with the Great Depression, which left most of the building empty—in fact, in the first year the building was open, the owners made as much money selling tickets to the observation deck as they did in rent.
If you were worried that we had run out of fun tricks in the Curves menu, well, worry no more. We have another handy little trick to help you manipulate the curves and further enhance your black and white images. There’s a big part of the Curves menu pane we haven’t even talked about yet, and that’s the black, gray, and white adjustment droppers at the bottom of the pane.
In the image above, you can see both the base photo and the unadjusted Curves readout of the image. Notice how the line from the lower left to the upper right is a nice clean, straight, diagonal line; our Curves, in other words, are pretty flat. The curves can seem a bit abstract, so let’s pick a spot on our photo and see where it falls on the curve. We’re going to click on the white side of the cup to sample that spot. Note: If you just click a spot and hold it, it will show you the spot on the curve, but if you hold CTRL and click it then there will be a permanent mark on the curve line:
Our work with black and white images makes these tools even more relevant. When we want to create high contrast images and really capture the crispness common in old black and white photos, it’s so easy to do so with a quick manipulation of the black, gray, and white points. Click on each one and select the darkest point in the image, a mid-tone gray point, and the whitest point in the image:
Now that we’ve played with a single point on the curve and seen how it affects everything, let’s reset the curve. Hold down the ALT key and the “Cancel” button in the Curves box will turn into “Reset”. Click to reset the curve back to the state it was in when you opened the menu.
Photos to edit Adobe Photoshop We’ll be using a copy of Adobe Photoshop CS6, but the techniques outlined in today’s tutorial should work just fine in previous editions of Photoshop, as the tools we’re using have been included in Photoshop for years.
For today’s tutorial, we’ll be using a simple photo we snapped of our morning espresso splashing down into the cup. It’s no sweeping view of Yosemite National Park, we know, but we like using low-key photos to showcase techniques because it puts more of a focus on the subtle changes of the technique itself.
We’re going to pick up where we left off in our previous photo tutorial. You have a photo you want to edit, you already converted it to black and white using one of the effective techniques we outlined, and now you’re ready to do some more tweaking.
We took our base image, seen above, and used the default filter in the Black & White adjustment menu to create a fairly neutral black and white base image. We’ll build on that below. What Are Curves and How Can I Take Advantage of Them?
The preset is essentially the curve we had in our prior image (except a bit smoother as it doesn’t have the extra pull on the highlights and lowlights that we put in). You can see how using the presents to jump in the direction you want to go and then finishing the job by making subtle changes to the existing curve is a much faster way to achieve the results you want than reinventing the wheel.
Just like our previous photo tutorial, you will need two basic things:
Because the curve is unadjusted, the input (the lower gradient bar) matches the output (the left-hand gradient bar). If we were to grab that little marker on the curve and pull it down it would darken the value, and if were to raise it then it would lighten the value. Let’s take a look at what happens when we do that in the next section of the tutorial.
How to Enhance Your Black and White Photos with Adjustment Curves

By following along with the battery of more advanced tips we have rounded up for this tutorial, however, you will be able to take your black and white photos to the next level. You may not edit every photo you take to this degree, but for the ones you really want to massage, manipulate, and otherwise enhance before hanging on your wall, the techniques can add just the right amount of pop to an image.
Envato Market has a range of items for sale to help get you started.
Last week we showed you how to convert your color photos to black and white photos. While the tips and tricks we shared with you yield awesome results, we’re back this week to highlight some powerful techniques to take your image to the next level.
Although many people are put off by the complexity of the Curves tool, we hope after a little tinkering you have seen how the extra effort is worth the time and yields really fantastic images.
Curves are possibly the most underused tool in the Photoshop arsenal, and they’re the heart of our tutorial today. Many people are put off of using them because they are not particularly intuitive and there are so many other tools available which are a bit easier to grasp out of the gate.
From here you can manipulate the curve and apply presets just like you did in the previous two steps of the tutorial.
Now, let’s look at that little black dot on that curve. Follow it with your eyes to the left gradient bar, and then follow it with your eyes down to the bottom gradient bar. That dot represents the slightly gray, almost white, value of the cup in the photo.
You can see how, in playing with the curves, it’s possible to capture elements of our earlier two example images. We liked the brightness of the cup but we also liked rich moody shadows. A little fiddling with the curves let us bottom out some of the shadows, spike the intensity of the highlights, and enjoy the best of both.
