Exposure merging using stacks
Exposure merging brings together images deliberately shot at different exposure levels to produce an image of a higher dynamic range. Such an approach is likely when areas in your shot are in high contrast and you'd like to bring together differently exposed areas as a solution.
Not to be confused with HDR merge, exposure merging composites images without creating an HDR image or applying HDR tone mapping, producing quicker and often more natural results.
Here are a few things to consider when shooting.
- To allow for perfect image alignment, use a tripod or ensure your camera is in a fixed position.
- Ensure enough photos have been taken to cover the full dynamic range required from the scene.
- If available, you can take advantage of your camera's auto bracketing feature to obtain photos at multiple exposure levels.
- Take advantage of continous shooting modes to automatically capture your images.
- Avoid flash photography.
To create an exposure merging stack:
- From the File menu, select New Stack.
- From the dialog, click Add to locate and select your images. Click Open to add the images to the stack list.
- Click OK.
- On the Layers panel, select the Mean or Mid-Range stack operator from the Stack Operator pop-up menu on the Live Stack Group layer.
