How to Apply Hue and Saturation Effects to PSD Images Using .NET

Hue and saturation control the vibrancy and mood of any photo. With Aspose.PSD for .NET, you can batch-adjust these properties for large sets of PSD images or automate creative color grading.

Real-World Problem

Manually changing hue/saturation for each photo is slow and unrepeatable. Automation ensures consistency and frees designers for more valuable work.

Solution Overview

Add or update the Hue/Saturation adjustment layer, set your values, and save. It’s all scriptable and scalable for bulk photo edits.

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) to process
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_huesat.psd";

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

Step 2: Add a Hue/Saturation Adjustment Layer 

var hueSaturation = psdImage.AddHueSaturationAdjustmentLayer();

Step 3: Adjust Hue, Saturation, and Lightness 

hueSaturation.Hue = -43;         // Range: -180 to 180
hueSaturation.Saturation = 4;    // Range: -100 to 100
hueSaturation.Lightness = 10;    // Range: -100 to 100 (optional)

Step 4: Save the Enhanced PSD 

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

Use Cases and Applications

  • Batch-color correct product photos
  • Apply creative color grading across campaigns
  • Enhance vibrancy for social and marketing assets

Common Challenges and Solutions

Extreme settings look unnatural: Start with small values for realistic enhancement.

Layer not visible: Adjustment must be above the target image layer.

Best Practices

  • Always preview final results before publishing
  • Script for batch folders to save time
  • Back up originals before automation
