Smarter Sharpening with the High Pass Filter in Photoshop

What if I told you that sharpening as we know it in photography isn’t real? That might be a little hard to believe but the truth is that it is actually impossible to make an image physically sharper after it has already been made. Sharpening a photo is simply an illusion. We can make a photograph appear to be sharper. Our digital images can be made to look sharper by adjusting the contrast of the pixels around the edges of shapes within the photo and this is what we are going to talk about today. We will look at how you can easily make your photos more sharp quickly using the high pass filter in Photoshop.

What is the High Pass Filter?

The high pass filter is just a method of creating a sharpening effect to your photo based on the pixels surrounding the contrasted edges of the elements within the image. While Photoshop has some dedicated sharpening tools(unsharp mask, smart sharpening) the high pass filter is the method I tend to use the most because I love the total control it gives me over my sharpening.

Using the High Pass Filter

To get started with sharpening using the high pass filter it is highly recommended that you complete ALL of your edits prior to performing the sharpening. This means that if you’re like me and do most of your processing in Lightroom and then export to Photoshop for finishing you will leave your high pass sharpening for the very last step. When you’re ready to sharpen, open your image in Photoshop.

Next, duplicate the layer by using keyboard shortcut Ctrl+J(Cmd+J for Mac). This is the layer where the high pass filter will be applied. I’ve renamed it “High Pass Layer” so it’s easier to see.

Make sure the new high pass layer is selected and then click on the ‘Filter’ tab and then ‘Other’ and lastly select ‘High Pass’.

You’ll notice an abrupt change to your image. It will essentially go completely grey. Don’t panic because this is exactly what we want to happen. But we have a choice to make and that is what radius we set for the high pass filter.

The radius controls the amount of pixels which are targeted around the edges where the sharpening will be applied. There’s a lot of wiggle room here and it generally is based on the resolution of your camera. The higher megapixel your camera the higher you can set the radius without causing unsightly effects such as halos and glowing edges. Let me show you what I mean. Here is the high pass filter with a radius of ‘1’…

And now here it is with a radius of ‘36’.

The higher the radius the more of the image will be affected. This particular photo was made with a 36.4 megapixel camera and I find a radius of ‘4’ to be the proverbial sweet spot. Adjust your radius accordingly.

Click ‘OK’ to apply the high pass.

But wait, this still looks horrible and gray and not at all what we want.

The next step is key. We have to change the blend mode of our sharpening layer. There are multiple choices here but the ‘Overlay’ option tends to work best with virtually all images and is the blend mode I use. After the overlay blend mode is selected we have what is essentially our final sharpened image.

Have a look at the difference the high pass filter has made in terms of sharpness. Here is the unsharpened photo….

And now the freshly sharpened version….

Closing Thoughts on Sharpening with the High Pass Filter

Don’t forget, not only can the high pass filter be applied easily but like any other layer adjustment in Photoshop the opacity can be adjusted until you reach the exact level of desired sharpness. Furthermore, adding in a layer mask to the sharpening layer can allow you to take complete control over the sharpening effect and only apply it to the areas of the photo you choose.

The best bit of advice when it comes to sharpening an image using any method is that less is usually more. Always remember that an over sharpened image is often less appealing than one that is slightly soft. Enjoy using the high pass filter in Photoshop!

A Quick Guide to Local Adjustment Presets in Lightroom

If you use Adobe Lightroom, I’m sure you’ve heard of develop presets and how they can jump start your creativity. But did you know that you can also create and save local adjustment presets just as easily? In this article I’m going to show you how to create and save your own local adjustment presets so you can make the most of your editing time in Lightroom.

What are Local Adjustments?

Local adjustment presets work a lot like develop presets in that they allow you to save certain combinations of edits for quick application later. The biggest difference between the two types of presets is that normal development presets generally work globally(affects the entire image) whereas local presets affect only the portions of the image you choose. These edits are applied either with either the local adjustment brush, graduated filter, radial filter, or a combination of the three. The great thing about local adjustment presets is that each preset can be applied by any of the local adjustment tools in Lightroom.

Here’s an example using the picture above. This is how it looked originally.

Let’s say we want to only lighten the leaf without disturbing the rest of the photo. Not only that, but the area could also use a little bit of a boost in clarity and sharpening. We can use the local adjustment brush and combine all this edits into one and apply them at the same time.

Now, that looks better.

This is an edit you might have use for in the future since adding a little exposure and clarity can might an image really pop. Instead of taking the time to go back in and adjust the sliders each and every time why not save this adjust as a preset? Saving local adjustments is even easier than saving a regular development preset because there’s no new folder to make and name, no check boxes to tick or untick. Everything is already set up for you and all you’ll need to do is make your adjustments and then name your new preset.

Saving the Preset

First, click the ‘custom’ drop down at the top of the local adjustments panel….

Find the bottom of the ‘Save current settings as new preset’ option at the bottom of the drop down menu and click on that.

Now it’s time to name your awesome new local adjustment preset. Just as with any other type of preset it’s a good idea to come up with a descriptive name that immediately tells you what the preset does. For this preset I’ve chosen ‘+Exp Clarity Sharp’.

And that’s it! Your new preset will appear as a freshly made preset name in the local adjustment presets dropdown menu.

Final Thoughts on Local Adjustment Presets…

Like any other preset in Lightroom, local adjustment presets save you time by eliminating the need to change multiple adjustment sliders each and every time you want to use a particular edit. Making a local adjustment preset is one of the easiest tricks you can use to speed up your post processing. Remember, every preset you make can be used with all the local adjustment tools in Lightroom. That means the adjustment preset we made above can also be applied using the radial and graduated filter as well. Local adjustment presets are great. Use this guide and find out for yourself!

Effective Black and White Conversion in Lightroom

In a way, black and white photographs were part of the reason I became interested in photography. I was no more than twelve or thirteen when my parents bought me a black and white Kodak disposable film camera. Remember those? It contained one roll of black and white 35mm film. Everything was set for you…just wind, click, and repeat. The thirty six exposures from that roll of film displayed an alien world. No colors, just shades of grey and contrasts of light. I was dumbfounded at the power that even these simple images could convey.

A picture from that magic roll of film….

Fast forward over twenty years and we find ourselves in the middle of the roaring age of digital photography. Now, we can see the world with two different sets of eyes: one in color, one in black and white. In our digital darkrooms it’s easier than ever to make professional quality black and white conversions from your RAW image files. In this tutorial we’re going to show you how to take your images beyond black and white using Adobe Lightroom.

More than Desaturation

There is more than one way to convert your images to black and white in Lightroom. We start with this image….

Sure you can grab hold of that saturation slider and simply set it to zero. This works. But you lose so much due to the nature of the desaturation.

The photo is somewhat flat after setting the saturation to “0”.

While the color has been removed, so too have the luminance values of those colors. Luminance values are the brightness values of the specific colors within the photo. It’s these differences in lights and darks that make a strong black and white image. Without being able to control each colors luminance we are left with a flat and often uninteresting image. The most effective method for converting your photo to black and white is to convert it to grayscale and then adjust the image with the black and white portion of the HSL Panel. It’s incredibly easy and powerful tool for working with black and white photos. You’re about to learn how to do it right now!

The Grayscale Conversion

Changing our images to “black and white” actually means we are converting them to “Grayscale”. No, grayscale isn’t some kind of mythological skin condition…. Grayscale is simply the term used to describe black and white photos which are in reality shades of gray and not only black and white. To convert your image to grayscale, click the black and white treatment option at the top of the Basic Adjustment panel.

Which gives us this grayscale image of our original photo.

You can also achieve the same result by jumping directly to the HSL panel and clicking the black and white tab.

Basic adjustments can be made for things like exposure, contrast, clarity, ect., but remember that we’re about to do more work on the photo using the color luminance adjustment in the HSL Panel. These adjustments can affect the overall contrast of the image so its a good idea to keep your initial edits at a minimum.

Adjusting with the B&W Section of the HSL Panel

Now that we have a black and white image to work with it’s time to adjust them color luminance and really make our image stand out. You can adjust the sliders for each color to either darken or brighten them within the image but an easier way is to use the target adjustment option. It’s the little dot at the top left of the B&W section.

Using the target adjustment tool is useful since we can select the area of color we want lighten or darkened without actually having to remember the original colors. Simply click the target adjustment tool and then click the area of color in the photo. Just drag up or down to adjust.

In this photo, the sky is made up mostly of blue, reducing the blue luminance values can add some great dramatic effects to the sky.

The same is true for the other colors. Greens and yellows in the bushes can be brightened. The orange color of the ponies hair can be darkened. After some final tweaking in the basic panel we have this final black and white photograph.

Final Thoughts

Converting and processing your black and white images in Lightroom is an incredibly easy and fast process. It also will open up a whole new world of creativity for you and your photography. Think your photos aren’t black and white material? Try the techniques in this article and I can virtually guarantee you might begin seeing your images in a completely different light.

Going Vintage with Adobe Lightroom

Retro Made Easy

When we think of “vintage style” photographs what we may be actually envisioning is a photo that bears many of the characteristics of analog film photography. These characteristics include subtle nuances in film grain and development, toning, and contrasts. The variations and combinations of these traits are quite literally too many to count but generally most vintage style photo-looks can be accomplished with just a few ridiculously simply edits in Adobe Lightroom. Generally speaking, vintage looking photographs are slightly faded with significant contrast. There are also some very slight color tones that are thrown into the mix in order to give a finished photo that has that great earthy feel of a analog photograph.

We’ll show you how to go from a RAW image file to a fully processed final image that has a nice vintage vibe. Here’s the before and after to give you an idea of just how impressive the results can be using just a few quick edits.

For this particular tutorial, we will look at a basic editing workflow for producing images with a vintage feel. But remember, this is just one look you can achieve. Don’t be afraid to experiment with color tones and contrast or even adding grain to your photo. The results can be fantastic!

Basic Edits First

We begin with a simple, and let’s face it, quite lackluster RAW file. Before we start with the vintage processing let’s do some basic edits to bring the image up to par for further processing. It’s always a good idea to do this before any other changes are made.

The edits applied here included some adjustments to color temperature and highlights as well as some adjustments to contrast and clarity. A couple of graduated filters were also used to even out the exposures of the sky and foreground. Here’s our processed RAW file that is now ready to go vintage.

Tone Curve

The tone curve has an undeserved bad reputation for being complicated to use. Nothing could be further from the truth once you have a basic understanding of how it affects your photo. For our vintage photo, most of the effects will be made using the tone curve adjustment. In most cases, begin with the tone curve set in “RGB” mode and the click the points to roughly an “S” shape with the curve. To add more fading, slightly drag the left most control point straight up the graph. In the case of this edit, I also moved the control point a small amount to the right to achieve the look I wanted.

I want to add a little bit of blue tone to the entire image. While still in the tone curve panel switch to the blue channel by selecting the dropdown menu below the graph. Keep in mind that you certainly don’t have to tone YOUR image with blue. The blue hue simply adds another element to the photo especially in the shadows which gives it a more vintage style. You could even use red or green if you like!

Final Tweaking in the Basic Panel

Now that we’ve reached a happy place with our tone curve it’s time to switch back to the Basic panel for a few final adjustments. In this case I increase the contrast while also reducing the highlights. After that I bring up the shadows. The colors in the photo are still a little too bright for me taste so I reduce the vibrance slightly. The color temp is just a slightly on the cool side so I also increase the temperature to warm the entire image a bit.

Vignette or Nah?

Our final step in the vintage conversion is to apply a slight vignette to help draw the viewers eye into the image. In come cases the vignette might not be desirable as in others. With this photo the darkening of the corners adds more appeal to the moody nature of the frame.

Careful not to go overboard here. Be sure to experiment with the feathering and shape of the vignette as well in order to get just the right look.

And here is the final vintage-styled photo. A considerable change from the dull and flat RAW file we started off with at the beginning of the article.

The fun thing about manufacturing vintage style photos in Lightroom is the shear enormity of the editing possibilities at your fingertips. Try out different combinations of color and toning to give different washes to your photographs. It’s definitely an easy way to add a little unique charm to your images without spending hours at the computer.
