I’m back into the swing of photography and my latest assignment is to do HDRI photography. What is that you ask? It stands for High Dynamic Range Imaging. What this means is it is a compilation of the same image taken at different exposures.
The results can look amazing. Here’s my experiment with HDR.
Sunrise: Zero Exposure
For my assignment, I took HDRI photos of sunrise, noon and sunset at the same site with the exact same positioning and focus. It was extremely hard to do. For each time period, I took a photo at normal exposure with an f-stop at 7.1 and then took a photo overexposed by one, overexposed by two, underexposed by one and underexposed by two. I overexposed them through changing the shutter speed, never changing the f-stop. This simply means that the first photo looked normal and the other two were darker and lighter than the normal photo.
Noon: Zero Exposure
After shooting the photos the next step is to upload them to photoshop. There is a built in program that you can use labeled “HDR” and you can choose the correct images and it then creates a compilation of them. The overexposed bring out more detail in normally dark things and the underexposed photos add depth and warmth the the photos.
From there you can choose to adjust certain levels to make the photo to your liking. You can even take out any motion that could have disturbed one photo from the rest by selecting “no ghosts.”
Sunset: Zero Exposure
Can you tell the difference? Which do you like best? Try it and see if you like to use HDR!
