Our eyes have a very wide ability to see a full range of colours and tones. We can see into details in shadows and well as details bright areas.
Cameras on the other hand, have a limited ability to see in details and shadows. Using High Dynamic Range Photography, we can trick a camera into displaying a wider range details and colours than it normally would.
It works better on a sunny day, because there is a greater range of tones, deeper shadows and brighter highlights. So wait for a day when the sun to shine outside.
So you can see the differences between a sunny day and an overcast day, also try doing HDR on an overcast day.
Here are the steps to follow:
Normally we only take one photo, but in HDR, we take at least 3 photos, but for this assignment, I want you to take 5 exposures.
1. The first is the normal exposure
2. Take one photo at 1 stop over
3. Take one at 2 stops over
4. Take another at 1 stop under
5. Take the final at 2 stops under.
Here is a concrete example of a camera setting:
1. 1/60 at f/11
2. 1/30 at f/11
3. 1/15 at f/11
4, 1/125 at f/11
5. 1/250 at f/11
Note the f/stop remains the same, so the focus does not shift. These settings are just an example. Adjust your camera and ISO to the current conditions and take your exposure.
Here are extra steps you should follow to ensure you get an excellent photo.
• Use a tripod
• Do NOT move your camera.
• Look for a high contrast scene like in direct sun light.
