Focus Stacking in Joshua Tree National Park

As part of the Desert Institute class I was teaching in Joshua Tree National Park, we did a sunset at the end of the second day at the trailhead parking log for Ryan Mountain.  Across the road one of the participants found a composition that I liked a lot, so we talked about the possibilities.  He ended up with a nice photograph and moved on.  I spent a little more time on it because I saw that there was a depth of field problem that needed to be resolved.

The foreground was about 20 feet from the camera and the background was a least a quarter of a mile away.  At a focal length of 190 mm there was no way I could get that depth of field even with an aperture of f/32.  So, as you can see below, I did two shots, one focused on the bush in the foreground and the second focused on the outcrops in the background.  The plan was to use focus stacking to get a sharp image throughout.

Photoshop does an excellent job of focus stacking.  To get it started, I selected the two files in Lightroom and clicked Open as Layers in Photoshop… from the Photo menu.

Lightroom converts the DNG files to Tiffs and loads them into Photoshop where they are stacked as two layers, one on top of the other.

In Photoshop, select both layers and in the Edit menu first click Auto-Align Layers… and then Auto-Blend Layers…. It’s that easy.

Images with Impact – Contrast in Nature

Explore how haze affects the contrast in distant objects, how humans respond and how that knowledge can be used in your photographs.

Last year I started a series of articles under the general theme of Images with Impact. In it we are discussing things you can do with your images in Lightroom and Photoshop to enhance their impact. When I got to the topic of contrast I came to an abrupt halt. The more I thought about contrast, the more I wanted to begin that discussion with some real examples from nature. But to do that, I needed some photographs that illustrated what I wanted to share with you. And in Southern California, the types of photographs I wanted are only possible in winter. But it’s winter now. And I’ve been able to capture the photographs that I want, so now we’re picking up the series again.

What distinguishes a photograph created by the serious student of photography from one taken by a casual photographer? Many things to be sure. But one thing that stands out is a sense of clarity, a clear quality. The casual photographers’ photographs are just what the camera captures and are often like looking through a bit of haze and I don’t mean that they are out of focus. It’s the light. The effect may be subtle but it is very real. A more accomplished photographers’ photographs have a special quality to them, a quality that engages us, that draws us in and holds our attention. You might describe it as a crisp quality.  (You can click on the photographs to enlarge them.)

The serious student of photography skillfully applies contrast in the digital darkroom to achieve this look. But before getting in to how this is done, let’s step back and take a look at how we respond to contrast not only in photographs but also in nature.

In the following discussion I will use examples from nature to illustrate the affect contrast has on us. The idea is to understand how it works so that we can more effectively apply this knowledge to our photographs.

Two Minutes of Light

Luck favors those who are parepared – and patient.

You read this story again and again.  The setting may be different but the plot is always the same.

It’s a dreary, overcast day.  You had planned this photo session for months, scouting it on Google Earth for the best location, checked the sun position on TPE (The Photographer’s Ephemeris), and received inspiration from the photographs of other photographers.  You made travel plans and booked lodging.

You arrived early at the iconic location, having traveled across the country and driven many miles in a rental car to get there.  But as you approach the sky turns dark with low hanging, gray clouds.  The light is a disappointment but you walk out to a viewpoint and set up anyway.  You keep telling yourself that good fortune happens to those who are prepared.

The minutes tick by and the sun, unseen behind a thick cloak of clouds, continues its inexorable decent to the horizon.  Other photographers join you and you ask each other, “Will it happen?”  Most shrug their shoulders and reply, “It doesn’t look like it will.”  It turns chilly and a cold breeze starts blowing.  Many photographers mutter, “It’s not going to happen,” pack up their gear and head back to their cars and a warm meal waiting them in the comfort of a nearby restaurant.

Making a Photograph – The Four Pillars

Explore the four things that make a great landscape photograph – Fantastic Light, Strong Composition, Appropriate Sharpness and Optimum Exposure.

I’ve been giving a lot of thought recently to what goes in to making a great landscape photograph. It turns out there are four things, four pillars if you will.  Four, that’s a good number.  There are the four legs of a table or the four wheels of a car.  And not to forget the four sacred directions of the Native Americans.

In landscape photography the four pillars are evenly divided between the aesthetics and the technical.  So what are they?  The two aesthetic pillars are Fantastic Light and Strong Composition.  No surprise there.  The two technical pillars are Appropriate Sharpness and Optimum Exposure.  No surprise there either.  If just one of those pillars is missing, well, the table collapses, the image suffers.

Let’s look at them one by one….
