There’s nothing worse than coming upon an awe-inspiring landscape scene, setting up your gear, and capturing what you think is an epic photograph—only to discover that the image is soft when you review it on the computer. The are a number of reasons for unsharp images, and the tutorial below provides a “guaranteed” method for nailing focus every time.

Instructor Ian Worth is a professional landscape photographer based in Wales, and in this behind-the-scenes episode you’ll follow him on the Welsh coast while discussing his foolproof method for achieving natural looking images with optimum sharpness regardless of conditions.

So what’s the secret to Worth’s consistently sharp photos? It’s a straightforward technique known as “back-button focus” that many pros use when shooting landscapes, wildlife subjects, sporting events, and the types of outdoor images. Worth explains everything you need to know for doing this yourself in barely 12 minutes.

According to Worth, “back-button focus is a powerful technique for all types of photography and it allows us to have greater control over a camera’s autofocus system.” The first thing you have to do is disable the conventional autofocus function on your camera’s shutter button. Then you assign AF control to one of the customizable buttons on the rear of the camera. Some models even have an AF-On button designed specifically for this task.

By decoupling the focus function from the shutter button you can now compose your shot in the normal way and use your thumb to lock focus on a specific point within the frame by using the button on the rear of your camera. Worth demonstrates why this is a preferable approach, “particularly when you want to capture multiple shots without having to refocus—especially when you need to recompose the scene without altering the point of focus.”

You can use back-button focus with both single-point and continuous AF. Worth explains that one of the many advantages of this technique occurs when your camera is securely mounted on a tripod. In such situations Worth rotates the tripod head so that the focus point is in exactly the right place. Then he uses the back button to initiate focus before recomposing the shot.

Before pressing the shutter button to capture the photo Worth uses his camera’s zoom feature to confirm that the scene appears tack sharp on the rear LCD. He offers a few other simple tips for using back-button focus to achieve precision results.

We’ve been working through all the new capabilities of the latest Lightroom update, and today’s tutorial from the Photoshop Café YouTube channel demonstrates a powerful new feature that is nothing short of “stunning.” In less than eight minutes you see how the new Point Color tool works.

Instructor Colin Smith is an expert at all things Adobe, and in this episode he demonstrates the use of Point Color in Lightroom and Adobe Camera Raw to fix difficult color issues and remove tonal contamination in your images. As he says, “this would have been so difficult before, but now it’s easy.”

Smith begins with a quick explanation of how Point Color works, before jumping into a step-by-step demonstration of using the new tool. To get started he selects the Color Mixer where the Point Color option appears at the top right of the panel with a number of sliders underneath.

The first step is grabbing the Eyedropper and selecting a color within the photo that’s confirmed in a swatch above the sliders. In this case he chooses a green tone from the hedge in the foreground of his image. Now you can use sliders to adjust Hue, Saturation, and Luminance.

One helpful trick becomes available when you hold down the Option key on your keyboard. Then as you move the sliders you’ll see that the areas that are in color are those being adjusted, while the portions of the shot that appear in b&w will be unaffected by your adjustments. This makes it really easy to keep track of what you’re doing.

There’s a fourth slider beneath the Hue, Saturation and Luminance options that’s called Range. This one enables you to refine the enhancements you’ve made. Pulling this slider all the way to the left narrows the range of the selection. Conversely, moving the slider to the right does the opposite. And there’s a button that enables you to visualize whatever range you select.

With these basics out of the way Smith turns to a practical demonstration of how to isolate specific colors and enhance them in various ways. The lesson wraps up by illustrating the simple steps necessary for fixing unsightly color contamination to achieve an image with beautiful tones.
