High Dynamic Ranging or HDR is a light based imagery improvement technique which can be associated with 3D or virtual imagery. High dynamic ranging technology is usually used when the photographer has a dark image and wants it to have more contrast, thereby transforming the dark image into a much bright looking one. To put it in nutshell, HDR illuminates your dark image at a higher range, thereby adding to the depth of the image output.
Combining the following techniques, you can make your image output have a greater depth.
Taking snaps at same angle
Photos taken at same point of focus with several variations
For using the HDR effect, a camera that can capture photos at great luminance levels, is required. You should use two images in the jpeg type. Using a tripod would ensure that the pictures are aligned. One image can also be used to apply the HDR technique.
The steps that you should follow to apply the HDR effect are given below:
Use Photomatix Pro software with a recommended v4.1
Open the Photomatrix and select the Load Bracketed Photos on the left side of the window, in the WorkFlow Shortcuts window.
Select the ‘Align Source images’ option and click ‘Load’.
To control high ISO images, use the ‘Reduce Noise’ option
To handle images with a little motion blur, use the ‘Reduce Ghosting artifacts’ option
After conversion to jpeg type images, select the effect you want from the tray which is at the bottom
Once the image is ready, select ‘Tone Mapping’ feature
Set the strength value to 100 in the Tone Mapping option
Set your desired values for color and contrast
To add light effects to the picture, use the ‘Light Enhancements’ option
Setting values for the exposure, compressing tones and color balances, you will be able to see a preview of the output
Click the process button, when you see the desired preview of the output
Save the image and you will see the magic of the HDR effect
For RAW files,
Select the Batch Single Photo option
Load the image
Set the desired values for all those mentioned above
Run your settings
Convert the image to jpeg if you don’t see any difference
This way, you can improve your photos with better luminance and lighting effects.
