High dynamic range (HDR) photography allows photographers to capture a wider range of light than normal possible with a camera lens and sensor.
HDR can be used to make a photograph look similar to how our eyes see. For example, you can eliminate a blown out sky and shadows that are too dark. The effects can also be made more dramatic, making the photograph look hyper realistic.
I can talk about the science and effects behind HDR photograph, but I'll skip the lecture and jump right in.
1. In-Field Prepeartion (picture 2)
Take 3-5 five pictures that are about one stop (f/stop) apart. Make sure the exposure of the pictures you take capture both the darkest points and brightest points of the scenery, and some in between.
This is demonstrated in picture 2.
Now, upload your images to your computer and then open Photoshop.
3. Merge to HDR (picture 3)
Click File > Automate > Merge to HDR
Then browse and find the 3-5 pictures you took.
4. HDR Dialog Box (picture 4)
Although I am not incredibly knowledgable in this dialog box, I think any amount of skill in this area is taken from playing with the features.
The sliders will allow you to find adjustments (picture 5), but you can also use preset slider positions (picture 6).
For a more detailed process, watch the video tutorial I have included in this card. HDR is a very complex field of photography, so there is always more to learn.
@hikaymm I hope you enjoy this tutorial!
As long as you get the basic step of taking 3-5 images, there are many resources online that will create HDR style images without the use of Photoshop. :)
