Applying Image Effects 77<br />
5. (Optional) Check Infer film response curve to affect a tone curve needed<br />
to accurately process scanned images (from camera film). Otherwise, keep<br />
unchecked for digital camera use.<br />
6. Click OK. The Merge HDR dialog is displayed, showing a preview of your<br />
intermediate HDR image.<br />
Don't worry if your initial results look less than desirable. You're only<br />
half way towards your stunning image but you'll need to modify the<br />
HDR image using a series of adjustments next.<br />
To adjust your intermediate image:<br />
1. From the HDR Merge dialog, an image preview is displayed, along with a<br />
merge file list and merge settings. Optionally, uncheck an image from the<br />
upper-right list to exclude it from the merge.<br />
2. Drag the Compression slider to a new value—use your eye to judge the<br />
best merge results, but also the supporting Histogram to ensure that the<br />
tonal range fits into the visible graph without clipping. The option<br />
compresses or expands the dynamic range by dragging right or left,<br />
respectively.<br />
3. Set a Brightness level to make the image either lighter or darker.<br />
4. Adjust the Black Point slider right to shift the histogram's left-most edge<br />
making all affected pixels in the shadow region turn black.<br />
5. Reduce Local Contrast Radius to alleviate image "flatness" when<br />
compressing the dynamic range (see Compression above).<br />
6. Set the Temperature to give a warmer "reddish" or cooler "blueish" look;<br />
drag to the right or left, respectively.<br />
7. Adjust the Saturation value to reduce or boost the colour in your image.<br />
8. Check Output 16-bits per channel if you're looking for the highest level<br />
of detail in your merged output.<br />
9. Click OK.
