Chapter 5: Adjustments & Filters – Enhancing Your Images

Now we get to the fun part: making your photos look amazing. Whether it’s correcting a dark photo, changing a color, or adding a stylish effect, Adjustments and Filters are your go-to tools.

5.1 Understanding Adjustment Layers

We briefly mentioned Adjustment Layers in Chapter 4. They are the best way to apply color and tonal corrections because they are non-destructive.

How to Add an Adjustment Layer:

  1. Go to the Adjustments Panel (Window > Adjustments) or click the half-filled circle icon at the bottom of the Layers Panel.
  2. Choose an adjustment (e.g., Brightness/Contrast, Hue/Saturation).
  3. A new layer appears above your current layer, and the Properties Panel opens with settings.

The “Big Three” Adjustments:

  1. Levels (Ctrl+L / Cmd+L): Corrects exposure.
    • Black Slider: Controls shadows.
    • White Slider: Controls highlights.
    • Gray Slider: Controls midtones.
    • Tip: Drag the Black and White sliders inward until they touch the start of the “mountain” (histogram) to instantly fix flat, washed-out images.
  2. Curves (Ctrl+M / Cmd+M): The most powerful tool for contrast.
    • Click on the diagonal line to add points.
    • S-Curve: Drag the bottom part down (darker shadows) and the top part up (brighter highlights) to add “pop” (contrast).
  3. Hue/Saturation (Ctrl+U / Cmd+U): Changes colors.
    • Hue: Shifts colors around the rainbow (e.g., change a red car to blue).
    • Saturation: Intensity of color. (Be careful not to overdo it!).
    • Lightness: How bright or dark the color is.

Filters apply special effects to your image. Unlike Adjustment Layers, most filters are destructive by default.

Smart Filters (The Non-Destructive Way): Before running a filter, right-click your layer and select Convert to Smart Object. Now, any filter you run will be a “Smart Filter,” meaning you can edit or turn it off later.

Essential Filters:

  1. Gaussian Blur (Filter > Blur > Gaussian Blur): The most common blur. Great for softening backgrounds or creating a dreamy look.
  2. Unsharp Mask (Filter > Sharpen > Unsharp Mask): Don’t let the name simulate you—this sharpens your image. It looks for edges and increases contrast.
    • Amount: How much sharpening.
    • Radius: How wide the edge enhancement is.
    • Threshold: Prevents grain/noise from being sharpened.
  3. Liquify (Filter > Liquify): The “photoshop failure” tool—but powerful when used subtly. Push and pull pixels to reshape objects (e.g., slimming a face, adjusting a smile).

5.3 The Camera Raw Filter

Want the power of Lightroom inside Photoshop? Go to Filter > Camera Raw Filter. This opens a huge panel with sliders for Exposure, Contrast, Highlights, Shadows, Whites, Blacks, Texture, Clarity, and Dehaze. It’s often the first thing pros do to a photo.
