Montana Morning



Sunrise comes early in Montana, even at this time of year. We arrived at this location in Glacier National Park a little after 6AM, and there was already enough light in the sky to maneuver down to the lookout point easily.

Official sunrise time was 6:30, but these colors did not appear until 6:45, and by 7AM the show was over.

When photographing sunrise anywhere, from the mountains to the sea, it is important to arrive on site early and be ready long before Mother Nature’s light show begins. Once things start to pop, there is precious little time to think. You just have to shoot, shoot, shoot. I suggest taking a shot every five or ten seconds while the colors are strongest. Sometimes your eye does not see subtle changes at the time, but you will see them when you get back to download and edit.

When photographing sunrise or sunset, use a small aperture in order to maximize Depth of Field, and use a relatively low ISO if possible. The lower the ISO, the less noise you will have. In any case, try to use an ISO no higher than 400. Regarding shutter speeds, a slow shutter speed is rarely a problem when photographing sunrise or sunset, especially when the sun is not in the picture.

Rocky Mountain High

AFTER

BEFORE


I have arrived in the beautiful state of Montana. This is only my third visit to this incredible state, and each time I see and appreciate more of its unique beauty. I am currently in Glacier National Park with its spectacular peaks, beautiful blue lakes, and narrow winding mountain roads.

Today’s photo was taken on the drive through the park from the airport. It was late in the day and the air was a bit hazy, but this glacial valley was huge and beautiful, so I took a few shots.

I was disappointed when I downloaded it, but decided to see what Lightroom 5 could do. As is usually the case, Lightroom came to the rescue. With just a few quick modifications, the real beauty of the image was revealed. Here is what was done:

1. Decreased Highlights
2. Increased Shadows
3. Boosted Clarity (it is rarely necessary to raise Clarity more than 30 points)
4. Increased Contrast (this is only the second time I have ever used Contrast in Lightroom; usually it is too heavy handed and can over-do an image in a heartbeat; but because of the haze, it worked to cut through the mist and allow more of the color to show.
5. Graduated filter to darken the sky

So once again, Lightroom proved itself to be an invaluable tool. If you want to learn Lightroom or want to improve your skills, consider taking the next Awake The Light “Lightroom Unleashed” workshop coming up March 16 – 20, 2015, to be held in Richmond, Virginia. This is a convenient location, an easy drive from many places, and also with easy airport access. Details are not on the website yet, but if you are interested, please email awakethelight@charter.net for more information. This class generally fills quickly, so don’t delay.

TECHNICAL DATA
Shutter Speed 1/400 sec.  Aperture f/11.  ISO 400.  Lens: Canon 70-200mm f/4L IS, set at 70mm.  Camera: Canon 5D Mark III.  Handheld.

Yes Or No?


What's your opinion of  this image? Like it? Hate it? Why?

Let me know your thoughts. Do you find it serious or comical?

In case you need to know, it is a Great Blue Heron just taking off from a pond. His entire body is in the original image, but it was cropped to show just this section.

Email your responses to me at awakethelight@charter.net   I'll reveal how it fared in a few days. 

TECHNICAL DATA
Shutter Speed 1/2500 sec.  Aperture f/14.  ISO 800.  Lens: Canon 200-400mm f/4L IS with built in 1.4 extender plus an external 1.4 extender for an effective focal length of 784mm.  Camera: Canon 5D Mark III. Gitzo tripod with Really Right Stuff ballhead and Wimberley Sidekick.

Playing The Odds


Orchids are gorgeous flowers, plain and simple. But they are not easy to photograph.

These cultivated orchids inside a hothouse were especially difficult to photograph because of the unappealing background. Not only was the background unattractive, but it was quite close to the flowers. The closer the background is to the subject, the harder it is to use depth of field to blur the background. There is just not enough space between the subject and the background for depth of field controls to have much success.

What saved this image was the lighting, and how cameras react to contrast.

The flowers were lit by a bank of windows high up on the wall behind me. The light coming in was strong enough to light the white flowers well, but allowed the darker background to go quite dark by comparison. It was a high contrast situation - well-lit white subject with a darker background which appears almost black.

Our eyes, unlike a camera, are attuned to see detail in all areas of a high contrast scene. We do not see the degree of contrast the way our cameras do. So it is important to view the image on your camera's viewscreen to get a sense of how the contrast will appear in the image. Even so, you might have to use image optimization software to darken the background a bit more. In Lightroom 5 that is easily accomplished by moving the Shadows slider to the darker side.

Always pay close attention to your histogram, especially with high contrast subjects. It is easy to overexpose the bright tones. If you see the "blinkies" appearing in substantial portions of the image (also called the "flashies"  -  how long did it take the digital brainiacs to come up with those highfalutin words!?), then use Exposure Compensation to reduce exposure about 2/3rds of a stop. Take another shot and check the histogram again. If necessary, reduce exposure a bit more.

TECHNICAL DATA
Shutter Speed 1/1250 sec.  Aperture f/4.  ISO 1600.  Lens: Canon 70-200mm f/4L IS, set at 160mm.  Camera: Canon 5D Mark III.  Handheld.

One Good Tern Deserves Another


Terns are fast-moving flying machines. They can change direction in a heartbeat, with no warning. Trying to photograph these beautiful and delicate hunters can be quite challenging.

When photographing birds in flight, it is important to have your camera set properly. A high ISO of at least 800 on a sunny day and much higher, perhaps 1600 or 3200 on a cloudy day, is recommended. A high ISO will allow you to use both a fast shutter speed and a small aperture for good depth of field. It will also mean that your images will show noise (similar to film grain in the old days), so some noise reduction software is helpful. I use the noise reduction feature in Lightroom 5.

A shutter speed of at least 1/1000 sec for moving birds, and an aperture of at least f/11 or smaller will give you the best chances of freezing motion and keeping most parts of the bird sharp. But what is the best way to focus and keep things in focus as the birds quickly change position?

For Canon shooters, use AI Servo. Nikon shooters use Continuous. As mentioned in a recent blog, setting your camera for Back Button Focus is an important first step toward having full control over focus, regardless of what subjects you shoot. If you have not read that blog, check it out at http://awakethelight.blogspot.com/2014/08/back-button-focus.html

But back to AI Servo / Continuous, this control allows you to track a moving subject and keep it in focus as it moves. Depress the focus button and hold it down as you follow the movements of the subject. The camera's focusing mechanism will continually focus on the subject, sensing the change in distances between the moving subject and the camera. It's a little bit of magic.

While it is not foolproof all the time, it is quite good and generally is much faster and more accurate than attempting to manually focus on a fast flying bird. Your best chances of success are to combine this focusing method with setting your viewfinder to show only ONE focus point rather than the several focus points that most cameras are set up for. I set mine for only the center rectangle viewable in the viewfinder. I keep that centered on the bird's head as much as possible, guaranteeing good focus of the head and eyes. Then I crop later as needed if I don't want the bird to be dead center.

A question was asked about whether to keep your camera always set to AI Servo / Continuous regardless of whether your subject is moving or not. Some recommend that approach, rightly pointing out that even set that way, when you remove your finger from the focus button, the focus locks in and will not change until you press the focus button again. I have experimented with that for the past year or two. My conclusion, based on what works best for me, is to NOT leave the camera set to AI Servo / Continuous all the time. I found that occasionally I was absentmindedly keeping my thumb on the focus button at times when I intended to lock in the focus and be done. In addition to using AI Servo for tracking birds in flight and fast moving wildlife, I use it for macro with fairly good success, especially when it is breezy and flowers are blowing a bit.  But for scenics, still lifes, and other non-moving subjects, I generally use One Shot.

Simply Surprising


Sometimes you get a pleasant surprise. This image of a stream in the Great Smoky Mountains National Park is a favorite of mine. The sunset light was magical for just a few minutes, and I was very lucky to have been in the right place at the right time.

Because I like this image so much, I decided to enter it in the annual Professional Photographers of America image competition. I have entered scenics before, and they rarely do well. While the judges seem to like scenics, they are not wowed by them. Often they get just a ho-hum score, and frankly that is what I was expecting.

So I was happily surprised when this image was selected to become part of the organization's Permanent Loan Collection. I can only assume that the quality of the light was a big part of why the image did well. Whatever the reason, I am thrilled that one of my favorite images was a front-runner with the judges.

If you have an image you love, even if you fear that the judges might not respond well to it, go ahead and enter it. You never know when a surprise win will come your way!

Island In The Sky


Pre-dawn on a mountaintop. Cold. Awoke in the middle of the night to drive to the location in order to be set up at first light. Crazy? You bet! Exhilarating? Yes!

Sometimes to get the shot you have to suffer a bit. And sometimes, in spite of all your best preparation, the shot never happens. While this was not the shot I envisioned when I decided to head out in the wee hours, it still worked well enough.

I had hoped for a very windy day, and planned to use a slow shutter speed to blur the motion of the clouds. As it turned out, there was just a light breeze which caused some blur of the clouds in front of the low ridge, but not enough to move the thicker clouds very quickly. Even with this 30 second exposure the thick cloud cover looks stationary.

When photographing sunrise from a high mountain, it is best to arrive at least an hour before the officially stated sunrise time. That is because the sky begins to lighten long before the actual sunrise, and much earlier than if photographing at a lower elevation. Arriving that early means you will be setting your camera up in the dark, so bring a flashlight, or better yet, a headlamp to light your way.

Choose a small aperture of f/16 or greater for good depth of field. Focus will be difficult, but as soon as there is a hint of light in the sky, your autofocus will be able to grab onto an area of contrast. In this image it was where the dark trees met the lighter clouds.  You can manually focus as well, but I have better success with autofocus.

Live View is not the best choice in very low light situations, so I do not use it.

You will also need a sturdy tripod and either a cable release or a remote timer.

Back Button Focus


As promised, here is information on Back Button Focus (also called rear button focus).

In the old days before autofocus was invented, the shutter button had only two functions: press down partway to take a meter reading, and then press down fully to take the picture. Focus was not tied to the shutter release. To focus, you manually turned the focus ring on the lens.

But since the advent of autofocus, we now have 3 separate functions occurring on the shutter button. That was a poor decision on the part of camera manufacturers. By tying the focus function to the same button as tripping the shutter, it  means that each and every time you press the shutter button, your camera attempts to re-focus. The net effect is that a series of images of the same subject can vary in focus even if neither you nor the subject has moved. Each time the lens has to hunt for focus, there is a good chance that it will not lock onto the precise area you want sharp.

But not to worry, there is an easy fix. Remove the focus function from the shutter button and put it someplace else. Most camera bodies allow you to do that by moving the focus to a button on the back of the camera body. This is still the same autofocus as always, you just press a different button than you did before. While you may balk at this at first, it is the best thing you can do for your photography of any subject, regardless of whether it is a stationary subject or a bird in flight.  If you have a choice, set the focus function to the "AF-ON" button rather than other buttons that might also give you that option.

Most Owner's Manuals are notoriously bad at providing this information. For virtually all cameras, it is a Custom Function setting. For some cameras two separate functions have to be set in order to remove the focus from the shutter button AND move it to a back button. The best way to get the information clearly is either on YouTube or other sites that will come up during a google search. This is the YouTube link   http://www.youtube.com/  Once on the site, type in your camera body in the search box near the top of the window. Here are a few links to get you started:

for Canon 60D  -  http://www.youtube.com/watch?v=1F4KFyz7KoE&list=PL703F1832A905834A

Once you have moved the focus function to a button on the back of your camera, you will use your thumb to activate that button, and your index finger to use the shutter button as always. It might take a little time to get used to it, but it will make your life so much easier. For this shot of a church in Charleston, SC, I focused on the chandelier in the ceiling, using my thumb to activate the back button focus. Then I took a series of shots from the same position, and did not need to focus again. Once I knew the chandelier was sharp, I could take many exposures by activating the shutter button, knowing that the point of sharpest focus would not change because neither I nor the chandelier was moving.

Sea For Two


Autumn in Alaska is a great time to see mother sea otters and their babies. The baby (on the right) is almost full grown, but still has his baby fat. Immature sea otters cannot dive because of their high proportion of body fat, and have to be dragged under water by their mothers. They don't seem to mind since that allows them to catch a good meal.

Sea otters are among the cutest animals around, and I never get tired of looking at them. They seem to like the people on the boats in their home waters, and almost always stare back at the camera. Very obliging subjects!

Because they float in place for long periods of time, it is relatively easy to find a pair or a pod of several and shoot away. For most subjects I prefer to use autofocus. It allows me to get sharper images most of the time. The trick for getting sharp images is to set your camera to have just one focus point in the center of your viewfinder, and as much as possible, place that center spot over the head or eyes of the animal. Then focus. It works best if you use rear button focus (also called back button focus), rather than focusing by using the shutter button as most cameras do. Rear button focus is a custom function found on most digital SLR cameras and many 4/3rds mirrorless cameras.  By removing the focus function from the shutter button, the camera will not automatically focus each and every time you press the shutter button, thereby providing more consistently sharp images when neither you nor the subject has moved.

(An upcoming blog will discuss rear button focus in more detail.)

Watch for announcements for 2 great photo tours to Alaska in August and September of 2015.

Blue On Green


Backlight is one of my favorite types of lighting, but it can be hard to deal with when photographing wildlife. This is classic backlight  -  all the light is coming from behind the Great Blue Heron, lighting the grass and edge-lighting his head and body. Notice that no light is striking the front of his body directly.  His body is being lit by ambient light, and some brightness reflecting up from the water.

When shooting backlit subjects, take a basic meter reading and then check the histogram. Sometimes it will be beneficial to increase the basic reading by one stop to make sure that the front of the body has received enough exposure. It is very easy to underexpose the main subject in a backlit scene.

I made at least one mistake when taking this shot. Just prior to my spotting this heron by the edge of the stream, I had been photographing birds in flight. In order to get a fast enough shutter speed to freeze their wing action, I had increased the ISO to 3200. But this shot did not need a fast shutter speed, nor did it need such a high ISO. The higher the ISO, the more noise is introduced into the image. I should have reduced the ISO to 800 for this series of shots, but I completely forgot that I had set the ISO so high. I was just happy to see this handsome subject standing in a great spot and beautifully lit.

Even so, using noise reduction in Lightroom removed most of the noise, so I was lucky that my mistake did not negatively impact this image. Most mistakes or oversights can be handled by Lightroom if you are careful in your optimization techniques.

TECHNICAL DATA
Shutter Speed 1/5000 sec.  Aperture f/8.  ISO 3200.  Lens: Canon 200-400 f/4L IS with added 2x external extender for an effective focal length of 800mm.  Camera: Canon 5D Mark III. Gitzo tripod with RSS ballhead and Wimberley Sidekick.
