HDR Photography – The Facts

Posted: 23 Jul 2013 04:42 PM PDT

The rise of beginner digital SLR cameras has generated a great new following in photography. Amateur photographers find they now have more control over their photographs and ample opportunity to experiment outside the ‘point and shoot’ mentality. No longer do they have to wait until the whole roll of film has been exposed and then processed, often finding that the exposure wasn’t right on that one, or it was out of focus on another. Now the shots can be viewed immediately and appropriate corrective steps taken at relatively little cost. No longer ‘a moment lost’.

This rise in popularity of photography has also spawned many post-processing computer applications. Admittedly some were around before the digital age, but many more have been born into the age, and one particular post processing methodology – HDR, or High Dynamic Range, is rapidly gaining in popularity.

High Dynamic Range (HDR), as the name suggests attempts to extend the light and tonal range of images taken under normal conditions, and once a balanced HDR image is compared with the original shot the results are often outstanding. Ever hear the expression, “You just had to be there’, when someone is showing off photographs? What they are really saying is that their camera just cannot compete with the human eye when capturing the total range of light and dark areas in an image. OK. So it is about light – right? So why don’t we take more than one shot of the same scene at different shutter speeds and then combine them in a way to get the best of all of them? That is exactly what we do to prepare for HDR processing. Here are the requirements and steps to generate an HDR image.

You will need:

1. A camera with the capabilities to adjust exposure settings (bracketing preferred). If you have a camera with a bracketed function and multiple shot capability, with a quick scan through the manual you will find out how to take say three shots of the same scene – one at normal exposure, one say two stops below normal, and another two stops above.
2. A sturdy tripod. If you are going to be taking multiple shots it will help if there is as little camera movement as possible between shots.
3. A high contrast scene. HDR works best here. An HDR photograph of a grey card will always be just a grey card, but one of a threatening thundercloud formation over a sunlit landscape can make one drool!

4. You will need some HDR processing software. I use Photomatix. It has good reviews and I get good results out of it. It is also very flexible in generating images from the surreal to the sublime.
5. You will need some time to learn and experiment. It doesn’t all happen by magic – you do actually have to work at it.

How to produce and HDR image:

1. Find your high contrast scene.
2. Place your camera on a tripod and if possible use a remote control to operate the shutter. Also if you are shooting with a remote, cover the eyepiece.
3. Preferably set your camera to shoot RAW images. These images will contain so much more exposure detail than JPG.
4. Set the camera to aperture priority. This will maintain the aperture setting to your chosen value and vary the shutter speed to obtain different exposures without upsetting depth of field.

5. Set the camera to manual focus and focus on your scene.
6. If possible select Auto Exposure Bracketing from your camera menu options, and select multiple shot mode.
7. Take your three shots.
8. Back home download your photographs and import them into an HDR processing application. Generate the HDR (which will look awful on the limited capabilities of your monitor), and then tone map the HDR to your liking. There it is!

Note: if you don’t have bracketing or multiple shot then you will have to manually change the shutter speed between shots – but don’t move the camera!

The good and bad about HDR:

1. Good side. Spectacular images can be produced with the right scene and the right tone mapping.
2. Good side. The process is simple and flexible – you are the maestro!
3. Good side. It lends a ‘fresh string to your bow’.

4. Bad side. It takes time to get it right. It’s a bit like riding a bike. You get the basics weighed off and then you start on the tricks.
5. Bad side – well, a consideration. Not all images lend themselves to HDR imaging. High contrast images work best.
6. Bad side. HDR will always introduce a degree of noise into your images. This looks like grainy film.
7. Good side. This has been recognised. Some noise can add a special effect, but, there are now software applications to remove or limit the noise. Noiseware is one of them.
8. Bad side. You can go completely overboard with HDR and produce some of the most hideous images imaginable. Take it easy and focus on creating an image that you feel truly represents what you – or your eye, was seeing.
9. As stated previously, not every one will turn out a success so be patient and learn.

What It’s Like to Be a Photojournalist

Posted: 23 Jul 2013 01:41 PM PDT

Photojournalists can’t rely on elaborate lighting equipment or Photoshop to craft award-winning shots. Instead, they must to wait for the crucial moment when all elements of their photographic story come together. Every day they are challenged to combine context and aesthetic to tell a visual tale.

In this video, photographers from the 2013 Pictures of the Year International Awards share their insights about what it’s like to be a professional photojournalist (for those of you reading this by email, the video can be seen here):

The responsibility of a photojournalist is to document situations for the world to see. Paul Hansen describes his role as a “voyeur of life.” His images bear witness to realities that others may never experience. Similarly, Judy Walgren sees it her job to give a voice to people whose predicaments may otherwise go unnoticed.

All of the photographers in the video discuss the significant impact of their photographs. A photo of an event unfolding is a piece of instant history that captures a distinct moment in time and lets the viewer think about what happened before and after the shutter clicked.

According to the featured photographers, the key to success as a photojournalist is to be an empathetic storyteller. Though the journalism piece of the career is vital to success, it’s even more critical that a photojournalist can relate to his or her subjects. The photographer must put herself in each subject’s shoes in order to understand the story and the emotions that are to be shared.

Interesting Photo of the Day: Lightning Photograph Achieved After a Four Year Struggle

Posted: 23 Jul 2013 12:11 PM PDT

Have you ever had an idea for an image in your head and spent days, weeks, or months trying to produce it. How about four years? That’s how long this photographer (known as wmbpix on social media) spent watching the weather and chasing storms until he was finally able to capture the image he had imagined:

Perseverance is the lesson here. Even if you there’s a low chance of you getting your ideal image, it’s better than giving up and having no chance. After four years, you would think that this photographer would have given up on getting a good lightning shot. But one morning, he saw a storm off the coast on the radar, grabbed his tripod, and tried once more. And this time, he succeeded.

“4 years of trying to be in the right place at the right time for a good lightning shot. Then one morning I saw a storm on radar off the coast of Savannah Ga. Grabbed my tripod and headed to the Island to try. This one made me very happy. This was shot at Tybee Island Ga”

For further training, we have an article on how to capture lightning

Police Photographer Leaks Arrest Photos of Boston Bomber

Posted: 23 Jul 2013 11:06 AM PDT

Recently, Rolling Stone released its controversial August 1 issue, its cover emblazoned with a self-portrait of Boston Marathon bombing suspect Dzhokhar Tsarnaev:

In response to the cover, Sergeant Sean P. Murphy, released photos he took during the teen’s capture on April 19, 2013, in Watertown in an attempt to stop the glorification of the suspect.

The album below highlights Murphy’s photos of the arrest, including actions leading up to Tsarnaev’s apprehension, images of the bloodied suspect with a laser pointed at his forehead, and evidence of his medical treatment following capture by police (for those of you reading this by email, the album can be seen here):

Now the photographer, a 25-year-veteran of the Massachusetts State Police, is on restricted duty while an internal investigation is conducted to identify whether or not Murphy’s actions violated policies. Federal prosecutors worry that the public release of Murphy’s photos, which may be considered evidence, threatens the integrity of Tsarnaev’s trial.

State Police Colonel Timothy Alben says it’s not likely that Sergeant Murphy will lose his job, but he will be held accountable for his decisions. Though many are criticizing the photographer’s actions, he also has a large group of supporters who are praising the publicity of his photos.

Especially when it comes to high-profile trials, photographs may hold more power than many photographers realize.
