How to Auto-Enhance Brightness and Contrast in PSD with .NET

Brightness and contrast adjustment is the first step in professional photo correction. With Aspose.PSD for .NET, you can apply this fix to one or hundreds of PSDs in seconds—no manual Photoshop required.

Real-World Problem

Bulk photo assets often suffer from poor lighting or contrast. Manually adjusting each PSD is too slow for marketing, publishing, or archival projects.

Solution Overview

Script the addition and adjustment of Brightness/Contrast layers in your PSD workflow for instant, repeatable quality improvement.

Prerequisites

  1. Visual Studio 2019 or later
  2. .NET 6.0 or later (or .NET Framework 4.6.2+)
  3. Aspose.PSD for .NET from NuGet
  4. PSD file(s) for enhancement
PM> Install-Package Aspose.PSD

Step-by-Step Implementation

Step 1: Load the PSD File 

using Aspose.PSD;
using Aspose.PSD.FileFormats.Psd;

string inputFile = "./input/photo.psd";
string outputFile = "./output/photo_enhanced.psd";

var loadOptions = new PsdLoadOptions() { LoadEffectsResource = true };
PsdImage psdImage = (PsdImage)Image.Load(inputFile, loadOptions);

Step 2: Add a Brightness/Contrast Adjustment Layer 

var brightnessContrast = psdImage.AddBrightnessContrastAdjustmentLayer(32, 50);

Step 3: (Optional) Fine-Tune Adjustment 

brightnessContrast.Brightness = 40;  // Range typically -100 to 100
brightnessContrast.Contrast = 60;    // Range typically -100 to 100

Step 4: Save the Enhanced PSD 

psdImage.Save(outputFile);
psdImage.Dispose();

Use Cases and Applications

  • Instant fix for underexposed or low-contrast images
  • Batch enhancement for e-commerce, marketing, or archive
  • Pre-processing for advanced creative workflows

Common Challenges and Solutions

Over-enhancement: Test adjustment values for best results on your photo set.

Layer not visible: Ensure adjustment layer is above the image layer in your stack.

Best Practices

  • Preview results in Photoshop before publishing
  • Keep a copy of the original file for comparison
  • Script for batch jobs to save time
