This tutorial by Masters of PixInsight Co-Founder Warren Keller introduces the DeLinear script by Hartmut Bornemann, designed to simplify the process of converting linear images to a non-linear state in PixInsight. This script offers an efficient alternative to manual histogram transformation. Key points include:
Setting Up the Screen Transfer Function (STF):
- Learn how to prepare a well-balanced temporary stretch using the STF to guide the DeLinear script for optimal results.
Executing the DeLinear Script:
- With a single click, DeLinear applies a permanent histogram transformation based on your STF settings, eliminating the need for additional steps.
Fine-Tuning After DeLinearization:
- Warren explains how to check and adjust the black point and mid-tones using histogram transformation if necessary, ensuring that the shadows, mid-tones, and highlights are balanced.
This tutorial provides a practical guide to using DeLinear for a quicker, more streamlined image stretching process in PixInsight.
