Creative Sharpening With HDR Software

HDR software is most typically used to render shadow and highlight detail, but it also can be used to enhance tonal separation and detail in any range of tones, even in images with extremely low contrast. The very same tools that are used to compensate for HDR side effects can be used to sharpen any image.
When multiple bracketed exposures are merged into a single processed file, shadows and highlights that exceed the dynamic range of a camera’s sensor are compressed into the dynamic range of a digital file, taking the midtones with them. Depending on the HDR software used, a variety of tools are available to restore contrast and separation in midtones. If used aggressively, these tools produce the telltale signs of contemporary or grunge HDR artifacts: halos and texture accentuation. These are the very same artifacts that digital sharpening routines use more conservatively to make images appear sharper—only they look different.
Unlike the hard halo and line produced by the filter Unsharp Mask and more like the soft line produced by the filter High Pass, HDR sliders can give you still more points of control over line and texture, each with a slightly different flavor.

Julianne Kost’s CS6 Lookup Adjustment Test File

“The new Color Lookup Adjustment Layer in Photoshop CS 6 has several options (3DLUT File, Abstract, and Device Link) that are used to load different “looks”. These looks are achieved by remapping every color in the image to a different one using a lookup table (LUT). I think that many photographers and designers will find their resulting color shifts quite interesting. You can think of these tables as a sort of meta-adjustment, a way to apply pre-packaged adjustments (sometimes lots of adjustments together) in one step.”
Julianne Kost has created a file that you can download free and test all the new CS6 Lookup adjustments on your image. Simply open the file and replace the contents of the Smart Object in it with one of your own images. It’s a great way to visually compare the various results in a ring around.

Different sharpening techniques make the world look different. A world of difference can be seen between the thin hard line of Unsharp Mask and the broad feathered line of High Pass Sharpening.Can you choose a combination of both? Yes, you can! You can choose the texture of one, the halo of another, and the line of yet another, applying them either globally or selectively. You can customize the look and feel of detail in any image or image area with astonishing precision and flexibility.
