Photoshop: More ways to work with Channel Luminosity Selection

Idea #6:

Channel Luminosity Selection:

1. Ability to add and subtract from the selection.
2. Ability to designate an area to be selected.

For point 1, by using the shortcut Cmd+Alt+[number] the luminosity of a channel is loaded as selection. With Cmd+Alt+Shift+[number], the selection grows. But there is no way to subtract from selection (unless by clicking with the mouse on the channel's thumbnail). I think that can be solved by using Cmd+Alt+Shift+[- or +] in order to subtract or add from selection.

Point 2 maybe even more important than point 1, because it allows selecting a designated area by the user, instead of the default luminosity selection, which ranges from 50% of the mid tones to the highlights (or shadows, if the selection is inverted). The user should be allowed to select the starting and finishing points of the luminosity selection.

I thought 2 ways for solving these issues (and making it more intuitive and faster):

A) By using the Histogram Panel, by dragging and highlighting an area on it, that it should load the selected luminosity pixels as a selection, as shown in figure 1:

Figure 1


So the result of doing that will be a selection based on the area of the histogram that have been highlighted.

B) By creating a new Adjustment Layer:

It can be based in the same structure of the HUE Adjustment Layer, like figure 2 shows:

Figure 2


Or it can be this way (much better). Figure 3:

Figure 3


The selection can also be controlled by using the Click and Drag as suggested in the figure 1, as shown in the figure 4:

Figure 4


The overlaid highlighting over the histogram can be functional or just a mere graphic representation of the Range and Fade Selector. The "Fading" areas should be also be draggable in order to increase smooth the selection. However, the smoothing can be much better done with the Refining Selection tool and it can be ignored from this new tool.

In any of these cases, the adjustments should give real time feedback when growing or shrinking selection; we must see the selection going bigger or smaller and also, the highlighted area should be draggable as well.
