range of tones, not the overall distribution; I’d see more contrast, yes, but that gap at the left edge of the histogram is still there. Instead, I’ll click the Advanced Settings button and then drop the Blacks value until the histogram tones stretch almost all the way to the left (Figure 3-4).
FIGURE 3-4: Decreasing the Blacks value significantly balances out the histogram.
The histogram is now nicely stretched across the full range of tones, though I’d like to see more brightness in the midtones. For that, I prefer to increase the Whites slider and nudge the Shadows slider, although that pushes the exposure too far to the right. To compensate, I’ll back off on Exposure.
As you can see, working with these controls is always a balancing act. I like to illuminate a scene with Whites versus Exposure because the adjustments are more targeted; Exposure is really a big light cannon.
At this point, I can’t ignore the giant streaks of red indicating blown out pixels, so it’s time to drag the Highlights slider to the left until the clipping indications disappear (Figure 3-5).

Adjust White Balance
It’s time to fix the white balance and warm up this image. Luminar has a few different tools that could work, such as the Remove Color Cast slider in the Color tool, but the White Balance controls in the Light tool will do just fine.
White balance is especially important in a photo like this where water is a central feature, because off-color water streams are a fast indication that the color temperature of the image is wrong. To make the adjustment, I’ll select the White Balance eyedropper and then click a neutral gray—in this case, a spot on the bridge (Figure 3-6). I can make the same adjustment by moving the Temperature slider a bit, but the eyedropper gets me close to a more appealing color temperature.
FIGURE 3-6: That’s more like it: warming up the white balance removes the blue tint.
Since I’m looking for a warm, colorful appearance for this photo, I’ll increase the Temperature value a bit higher (8844) than what the eyedropper picked (7732). That introduces a slight color cast on the water, but I’ll deal with that later.
Punch Up the Foliage
With the exposure and white balance adjusted, it’s time to get creative. To make those almost-orange leaves more dynamic, I’ll open the Color tool. It may be tempting to increase the Saturation and Vibrance sliders—MORE COLOR!—but the greens are already pretty prominent. So, let’s take a more tactical approach by clicking the Advanced Settings button to reveal the individual color controls.
When I select the orange button and increase the Saturation slider, and also decrease the Hue slider slightly, the drab, pale-orange leaves become more like what I have in my mind. I’ll also tweak the yellow channel, increasing Luminance and Saturation to draw out more color from amidst the green (Figure 3-7
