TK Actions Quick Tip: Three ways to use Levels and Curves

There are a lot of features packed into the TKActions V6 panel. Not only does it quickly generate luminosity masks, but it also allows them to be modified and output in a variety of ways. In addition, the V6 panel also provides access to most of the common Photoshop functions photographers use to develop their images. Curves and Levels are a natural part of many techniques, so different V6 modules contain buttons and menu items to appropriately access these adjustments. In this new Quick Tip video, Sean Bagshaw reviews the locations of the Curves and Levels options in the V6 panel and demonstrates how each can be used.

There are three distinct Curves and Levels adjustments found in the V6 panel:

  1. In the “Layer Mask” menu of the Combo/Cx modules. Buttons in this menu are designated by the familiar Photoshop icons for these layers. They create the corresponding adjustment layer with a white “reveal all” layer mask if there is no active selection. If there is an active selection, the selection is incorporated into the the layer mask as the adjustment layer is created. These buttons work similarly to the items in the “Layer Mask” menu accessed at the bottom of the Layers panel. However, there is one advantage to using the Combo/Cx buttons and that is that they automatically open the Properties panel after the adjustment layer is generated. Most adjustment layers do nothing until you adjust the layer’s properties. Anticipating this, the panel opens the Properties panel so users can go directly to making their adjustment after creating the layer.
  2. In the MODIFY section of the RapidMask2 module. The RapidMask2 module is all about making pixel-based masks, like luminosity masks. While the panel can make dozens of different calculated masks as a starting point (Lights, Darks, Midtones, and Zones), there are actually an infinite number of possible masks for any pixel-based value. The MODIFY section allows you to fine-tune any mask to better match the pixels in the image, and Curves and Levels adjustments fit nicely as one of the modification options. The MODIFY buttons open a separate window where users can watch the mask change in real time as the adjustment is made. There is also a MODIFY section in Layer Mask Mode, and Sean’s video demonstrates how Curves and Levels work in this section as well.
  3. In the “Layer” button menu in the OUTPUT section of the RapidMask2 module. This is the final location for Curves and Levels in the V6 panel. “Layer” menu items automatically apply the current Rapid Mask that has been created by the module to the adjustment layer that’s created. It’s a one-step process to go from mask creation to being able to actually use the mask to adjust the image. Besides the efficiency of using this output process to deploy masks, there are two additional advantages. The first is that no intermediate 8-bit selections are used. It’s a direct channel mask to layer mask process, which is 16-bit to 16-bit. The quality of the layer mask is therefore identical to that of the original Rapid Mask. The second advantage of this output method is that the Properties panel for the new adjustment layer once again automatically pops open. Adjustment layers need an adjustment by the user, and this output method lets you get right to it.

Sean, as usual, does a great job reviewing and demonstrating these different options. I’m sure you’ll feel more confident using them after watching this video.
