lightest areas, while a higher number affects a wider range of tones. In general, I
suggest keeping this slider at or below 50 for both shadows and highlights.
Radius works in a similar manner to the Radius slider on the Sharpen tab. How-
ever, rather than looking for contrast between edges, it determines how wide of
an area to use when deciding what the shadow or highlight area is.
I suggest checking the More Accurate option for the best results. It does increase
the amount of time needed to apply sharpening to the image, but the end result is
worth the time.
Finally, if you find yourself frequently using the same adjustments, you can save
them for future use by clicking the Disc icon
next to the Settings list.
Saving As TIFF
When all your efforts to produce the ultimate image from your RAW image are com-
plete, you'll obviously want to save your changes. Saving as a TIFF file will give you
the most flexibility and retain all of the quality contained in your image. If you do your
edits with adjustment layers (and I recommend you do so), saving as a TIFF file will
retain the layers, making adjustments for other uses later much easier.
Note: Why not PSD? At one point, PSD was the only way to save files with layers. Now that TIFF sup-
ports layers, I recommend saving as TIFF for wider compatibility with other applications and for future
compatibility if the PSD format changes.
After selecting TIFF as the file type, the Options dialog offers several choices, as
shown in Figure 7.15.
The TIFF Options dialog offers a
number of settings for your file,
including compression and layers.
