Exposure Merge (Step 1 window)
For more information about taking photos that work well with Exposure Merge, see Taking photos for HDR processing.
Exposure Merge uses a three-step process:
| • | Merge — Choose your merge settings, and if required, apply custom editing. |
| • | HDR Adjustments — After merging your photos, you can adjust them and save the results to an editable HDR file before finalizing the merge and fine-tuning. |
| • | Fine-Tune — Refine your image, with noise-reduction and sharpening options, along with some other familiar tools from the Adjust workspace. When you’re done, you can save to a standard file format and close Exposure Merge. |
Please see the topics below for more detailed information about each step.
| • | Camera response curve profile — applies a curve adjustment to the image, based on the known characteristics of the sensor in your camera |
| • | Alignment — Choose between Feature-based (detects features in the photos) or Edge-based (detects edges within the photos). |
| • | Custom editing — Choose which areas you want to keep (Brush in) or remove (Brush out) from each photo. Often, custom editing is applied to remove "ghosting" — the semitransparent effect caused by merging photos that captured moving objects. |
The final step is fine-tuning the merged image before you exit Exposure Merge. The controls in the Fine-Tune window are based on the controls in the Adjust workspace. For more information, see Using the Adjust workspace.
| • | Digital Noise Removal is a great tool for cleaning up noise that can result from merging photos. |
| • | High Pass Sharpen can help reduce blurred areas that may result from movement between photos. |
| • | Smart Photo Fix and White Balance let you tweak the colors. |
| • | To brighten the entire image, try adjusting Brightness/Contrast. To brighten only the dark areas, try Fill Light/Clarity. |
| • | Local Tone Mapping and Fill Light/Clarity can be used to further enhance details in the image. |
