PixInsight is a powerful, specialist image-processing application widely used by astrophotographers for calibration, alignment, integration, and advanced post-processing of deep-sky images. One recurring task in PixInsight workflows is working with Linear/Exponential (L/E) response and with linked image data across processes and scripts. This article explains the concept behind "LERAR link" (interpreted here as Linear/Exponential and resource linking methods used in PixInsight), clarifies common use cases, and provides step-by-step workflows and troubleshooting tips to help you integrate linear and non-linear processing and link images effectively across PixInsight processes and scripts.
Q: Why is it called “Lerar Link” in some YouTube videos? A: This is likely a phonetic spelling from a non-native English tutorial. The correct terms are “Local Normalization link” or “linear reference link.” The creator may have said “linear link” and it transcribed as “lerar.” pixinsight lerar link
