Color Correction Practice in Photoshop

Welcome to Day 30 of your Photoshop course! Today, we will put everything you’ve learned about color correction to the test. This session is dedicated to practicing full color correction on images that are either underexposed or overexposed. By the end of this lesson, you’ll have honed your skills in using adjustment layers and various color correction techniques.

We’ll start with a detailed step-by-step guide and finish with a quiz to assess your understanding of color correction and adjustment layers.

1. Introduction to Color Correction Practice

Color correction is crucial for ensuring that your images look vibrant and true to life. In this practice session, you will focus on correcting exposure issues—either underexposed (too dark) or overexposed (too bright) images. You’ll apply various color correction tools and adjustment layers to restore detail and balance.

Here’s what we’ll cover:

• Correcting Exposure Issues: Techniques for fixing both underexposed and overexposed images.
• Using Adjustment Layers: Applying Levels, Curves, and other adjustments for precise control.
• Assignment: Perform a full color correction on an image.

2. Step-by-Step Guide for Correcting Underexposed and Overexposed Images

Step 1: Open Your Image

1. Launch Photoshop and open the image you want to correct. It should be either underexposed or overexposed.
2. If needed, duplicate the original layer to keep a backup. Right-click the image layer in the Layers Panel and select Duplicate Layer.

Step 2: Correcting Exposure with Levels

1. Add a Levels Adjustment Layer:
   • Click on the Adjustment Layer icon at the bottom of the Layers Panel.
   • Choose Levels from the list.
2. Adjust Input Levels:
   • In the Properties Panel, move the Shadows (black) slider to the right to brighten the dark areas.
   • Adjust the Midtones (gray) slider to change the overall brightness.
   • Move the Highlights (white) slider to the left to recover highlight details.
3. Fine-Tune: Adjust the Output Levels sliders if needed to enhance contrast.

Step 3: Correcting Color Balance with Curves

1. Add a Curves Adjustment Layer:
   • Click on the Adjustment Layer icon again.
   • Select Curves from the list.
2. Adjust the Curves:
   • In the Properties Panel, you’ll see a diagonal line on a grid.
   • Click on the curve to add points. Drag these points to adjust the tonal range. Lift the curve to lighten the image or drag it down to darken it.
   • Use the Channel dropdown to adjust individual color channels if necessary (Red, Green, Blue).

Step 4: Use Brightness/Contrast for Final Touches

1. Add a Brightness/Contrast Adjustment Layer:
   • Go to the Adjustment Layer icon and select Brightness/Contrast.
2. Adjust Settings:
   • Move the Brightness slider to correct any remaining exposure issues.
   • Adjust the Contrast slider to enhance the image details.

Step 5: Save Your Work

1. Review Your Adjustments:
   • Toggle the visibility of adjustment layers to compare the corrected image with the original.
2. Save the Image:
   • Save your file as a PSD to retain layers and adjustments.
   • Export a JPEG or PNG for sharing or printing.

3. Tips for Effective Color Correction

• Use Multiple Adjustment Layers: Combining Levels, Curves, and Brightness/Contrast adjustments often yields the best results.
• Zoom In and Out: Zoom in to fine-tune details and zoom out to view the overall effect of your corrections.
• Check Histogram: Use the histogram to ensure you’re not clipping shadows or highlights.
• Use Layer Masks: Apply adjustments selectively using layer masks for more control over specific areas.

4. Assignment: Full Color Correction

1. Open an Underexposed or Overexposed Image in Photoshop.
2. Apply Levels Adjustment: Correct the exposure by adjusting shadows, midtones, and highlights.
3. Use Curves: Fine-tune tonal range and color balance.
4. Adjust Brightness/Contrast: Make final corrections to enhance image details.
5. Save and Export: Save your corrected image as a PSD and export a JPEG or PNG.
