HDR Photography, or High Dynamic Range Photography, is all the rage right now. With the advent of image-heavy social media platforms that call for eye-catching and dramatic photos (like Instagram and Pinterest), it isn’t any wonder why this artistic photography technique is even available on your iPhone. Not everyone loves HDR; some even argue that it’s more like digital imaging than real photography. I’m not going to take a position on the merit of HDR, but rather to explain more clearly what HDR Photography is, and when you should and definitely shouldn’t turn it on.
What is HDR Photography?
Remember that lesson on the histogram when we talked about situations of high contrast? If you need to freshen your memory you can take a look back at my previous lessons on histograms and exposure. In brief, high contrast most often occurs when you have a very bright sky casting harsh shadows on the foreground. In situations like these, it can be difficult for your camera to get the exposure right—your photo will likely be too bright or too dark. Taking your photo using HDR can fix that though, ultimately allowing you to capture the details in the sky without making the foreground too dark.
Here’s how it’s done: HDR photography uses a technique that involves combining multiple images into one. Basically your camera will take 3 photos at different exposures: one bright photo, one ‘normal’ photo and one dark photo. When the 3 photos are combined, the shadows will become brighter and the highlights become darker. The camera will take the three photos automatically by changing your shutter speed.
When to consider HDR:
Backlit Scenes: Photos with a bright sky and dark foregrounds greatly benefit from HDR. In this church I wanted to bring detail into the backlit ceiling and HDR allowed me to do that.
Landscapes: When photographing landscapes, there are often a lot of details that you are trying to pick up, both in the sky as well as the foreground. HDR can let you capture those details without making any one part of the photo look too dark.
When to avoid HDR:
Movement: In HDR you are combing multiple photos, so of course they all need to line up perfectly. That means no movement at all, what so ever. If there is movement then the photos won’t line up and you’ll end up with a ghostly-grandma-crossing-the-street effect, or blur, that looks something like this:
Highly Saturated Scenes: If you’re dealing with colors that are already very powerful, HDR may overdo it and cause your photos to look super-saturated and “fake.”
Once you get the hang of HDR Photography, you don’t have to stop at combining just 3 photos. If you really want to capture detail in your photos, there are programs like Photoshop or Photomatix Pro that allow you to combine 3 to 7 images, thus gathering all the detail possible. There are also photo-editing tools like Lightroom for desktop and Snapseed for mobile devices that allow you to create HDR-like photos without actually combining multiple exposures. We’ll go into photo editing techniques in a later lesson.
How to set HDR up:
Taking HDR photos on your DSLR may be as easy as switching on your camera’s built-in HDR setting. First set your camera to Aperture Priority. If you’ve got it available, turn on your camera’s in-house HDR setting. On my Nikon D7100, I have the HDR function set on the Fn button. I can quickly switch it on if I feel the need. Once HDR is turned on, flip the focus to manual throughout the photo series so your camera doesn’t shift your focus point between shots. As a best practice, you may also want to set a 2-second time delay so that your finger pushing the shutter doesn’t shake the camera and cause any blur.
Alternatively you can set up an Auto-Exposure Bracketing system and then combine the photos later on your computer using Photoshop. To set up Auto-Exposure Bracketing on my Nikon D7100, I would hold down the BKT button and choose how many photos I want to combine: 3 or 5. I then choose the difference in exposure between the photos, from .3 to 3.0 EV. The post-processing can get quite complicated, so I won’t go into it here, but there are plenty of YouTube tutorials available on how to combine multiple images in Photoshop.
Personally, I use the in-camera HDR on my Nikon D7100 combined with post photo editing in Lightroom and it works brilliantly. I don’t have to worry about combining photos and editing too much on my computer.
I don’t use HDR all that much unless I find it absolutely necessary. However, I do use it most of the time on my iPhone for pictures on Instagram. The HDR setting tells the phone to take a regular and an HDR image, so I can always go back and compare the two to see which I like better. Overall though, when it comes to media like Instagram, highly edited photos attract more attention and gather more ‘likes’.
HDR is a great technique when used under the right circumstances. All of these HDR photos were taken using my iPhone’s HDR setting and edited on my phone using Snapseed. Ultimately, remember that photography is an art and it’s up to you to create photos and memories that help you reflect on how you felt at the time the photo was taken. Play around with HDR and see what you think!
