This guest post is by Sean Ogle who I first met in Bangkok last year where we were able to experience the fun which is songkran on Khao San Road. Sean blogs at Location180.com, a blog aimed at helping others create businesses they can run from anywhere in the world and also runs DailyHDR.com and HDRSoftware.com. He is an avid photographer, world traveler, and beer connoisseur. The photo of him to the left was taken by me in Bangkok.
How many times have you been on a trip, seen something spectacular, and rushed to take your camera out to capture the moment? If you’re like me, this probably happens a lot.
Now, out of all of those memorable moments, how often does your resulting photo actually capture the scene exactly as you remember it?
Probably not many.
Enter HDR Photography
HDR stands for High Dynamic Range – which probably doesn’t mean a whole lot to many of you. Essentially there are limitations with traditional technology that only allow your camera to expose for certain aspects of a given scene.
For example if you’re shooting a beautiful beach sunset, you have to decide if you want to expose for the sky or the beach foreground – almost always one part of the photo will be under or over exposed.
Your eyes have the ability to process a much higher dynamic range than any camera does. So when you see something in person you can take in the bright highlights and dark shadows all at once.
A camera can’t do this as well.
This is why traditional photos usually don’t do a very good job of representing a scene as you remember it – because the dynamic range of a standard image is greatly reduced.
Many critics write off HDR as a gimmick, however there is significant value when done correctly – especially as it pertains to travel photography
So How Does HDR Work?
HDR photography is one of those things that falls under the category of easy to do, difficult to master – but the premise is pretty straight forward.
An HDR photo is actually a series of multiple images combined together using HDR Software.
A basic composition consists of three separate images taken of the exact same scene. The first image is properly exposed, capturing all of the mid-tones of the scene. The second photo is underexposed in order to capture the shadows. The third photo is over exposed, which allows you to get all of the highlights of the image.
Good HDR photographers will sometimes take up to 7 or 9 images (called brackets), to ensure that they have the full range of light necessary to compose their desired image.
When creating HDR it’s really important that the camera doesn’t move in between shots. So generally, unless you have a DSLR with a really speedy frame rate, you’ll want to use a tripod.
Basic Tools Needed for HDR Photography:
- A camera with manual controls (many point and shoots have these settings buried in their menus)
- A Tripod
- A Computer with HDR software installed
Creating an HDR Image
So once you’ve shot your three brackets, now what do you do? You’ve got one photo that looks ok, and two that are totally unusable.
That’s ok, the final result will look much different.
The next step is to use the special software to combine your bracketed shots into one image. There are dozens of options out there for this, but the two most popular are Photomatix and HDR Efex Pro.
Unfortunately these are kind of spendy, so if you’re a beginner looking to get involved in HDR photography you may want to try out Picturenaut which is free.
All you do now, is select the photos you want, adjust a basic couple settings and the software will do the hard work for you.
That doesn’t mean your initial results will be perfect, however.
With all HDR software, the initial result after merging your photos could be anywhere from “wow, that looks pretty good!” to “why would anyone want to make a photo look like this?”
It’s ok, that’s normal.
There are many more adjustments you can make after the photos have been merged to ensure that the final result is exactly what you were hoping for.
Luckily, there are hundreds of HDR tutorials on the internet that walk you through the most basic necessities, all the way through advanced techniques.
Why Spend the Time to Shoot HDR?
Ok, so we’ve covered the basics of how to do HDR, but a more important question is why should you shoot HDR.
As I alluded to earlier, this technique can replicate scenes in a way that traditional photography can’t. Because you can capture the full range of light, your final images (when processed correctly) will appear much closer to the way your eyes perceived the scene initially.
This is especially important when it comes to travel photography.
Over time the mental images you have of any given place begin to fade, and you rely more and more on the photos you took while you were there to remind you of what the place was like.
With HDR photography you have much greater flexibility to create something that matches the images you have in your mind – that’s pretty powerful.
That said, it certainly requires more forethought and planning in order to setup the shots and remember which photos go together.
Best Times to Use HDR
HDR is definitely one of those things that can be overdone and over used. You don’t want to use this technique all of the time, because when used incorrectly it can lead to oversaturated images that look like they came straight out of a video game. This defeats the purpose of preserving your travel memories.
So when is the best time to use it? Generally you can use HDR any time there is a large amount of contrast between light and dark in the scene. Here are some examples:
- Sunrise or Sunset. During sunrise or sunset you can take some of the best photographs of your life, or the worst. Due to the increased shadows and the propensity to overexpose the lowering sun, sunsets make for the perfect opportunity to test out your HDR skills. By taking three exposures and capturing all aspects of the light, you can expose all of the details in the forefront that you might normally miss, while not overexposing the sun.
- Stormy or Cloudy Scenes. I often tell people the easiest thing to shoot when just getting started is clouds. Often times in a traditional photo even the most interesting cloud formations can turn out flat. When you capture all of the shadows and highlights separately you can make them really pop. This doesn’t always give you the most natural of looks, but it’s great for demonstrating the power of HDR.
- Low Light. This particularly holds true for city or urban shots. Some of my favorite HDR shots are of unique older buildings with lots of texture. This can be particularly cool around dusk. Normally when shooting urban scenes at this time you’ll sacrifice detail in the buildings – but with HDR you can still expose everything around you.
- Interior Photography.Due to poor lighting conditions inside, HDR is perfect for shooting interior photography. Smart real estate agents know the power of using HDR to do a much better job of making the interior of a home look good for their listings While traveling, you can use HDR inside cathedrals or museums to significantly improve your images as well.
Closing Argument for HDR
Getting started with HDR photography isn’t easy. It requires both a monetary and time investment that many people aren’t willing to commit to. However, as you can see from the photos in this post, the results can be pretty astounding as your skills progress.
So before your next big trip, think about the images that you want to come home with, and make a conscious decision about whether or not HDR is right for you.
