Image Adjustments and Effects 87

To adjust your intermediate image:

1. From the HDR Merge dialog, an image preview is displayed, along with a

merge file list and merge settings. Optionally, uncheck an image from the

upper-right list to exclude it from the merge.

2. Drag the Compression slider to a new value—use your eye to judge the best

merge results, but also the supporting Histogram to ensure that the tonal

range fits into the visible graph without clipping. The option compresses or

expands the dynamic range by dragging right or left, respectively.

3. Set a Brightness level to make the image either lighter or darker.

4. Adjust the Black Point slider right to shift the histogram's left-most edge

making all affected pixels in the shadow region turn black.

5. Reduce Local Contrast Radius to alleviate image "flatness" when

compressing the dynamic range (see Compression above).

6. Set the Temperature to give a warmer "reddish" or cooler "blueish" look;

drag to the right or left, respectively.

7. Adjust the Saturation value to reduce or boost the color in your image.

8. Check Output 16-bits per channel if you're looking for the highest level of

detail in your merged output. Then click OK.

9. From the next dialog, you'll be asked if you want to save the intermediate

HDR Image or just continue as an untitled project.

Click Yes to preserve the HDR image. This saves having to select,

align, and merge images again, but you'll still need to reapply any

adjustments previously made. Select a file location, file format, name

for your file, then click Save. The file format (OpenEXR .exr, Radiance

.hdr, or HD Photo .hdp) can be chosen from the drop-down menu.

Click No if you don't need to preserve the HDR image (you'll have to

select, align, and merge again). Your merge results will be the basis for

an Untitled project.

If you've created an intermediate HDR image, it can be opened as for any

other file (see p. 20).
