ADVANCED COMPOSITING & RETOUCHING - Chapter 1, Exercise 2
Matching Fundamentals Techniques to the Advanced Chapters Built on Top of Them
====================================================================================

QUESTION:
List three techniques from Raster Editing Fundamentals that this course assumes
are already comfortable, and match each to the specific chapter of this course
that builds directly on top of it.

SOLUTION / EXPLANATION:

Three examples (several other valid pairings exist - any three genuine matches
from the chapter's own recap list are acceptable):

1. LAYER MASKS (Raster Editing Fundamentals, Chapter 5)
   -> builds into ADVANCED MASKING (this course, Chapter 2)
   A basic layer mask hides or reveals part of a layer using a simple painted
   black/white mask. Chapter 2 goes further with channel-based selection -
   using an image's own color channels to build a far more precise mask for
   fine, high-detail edges like individual strands of hair, which a painted
   mask alone can't handle cleanly.

2. ADJUSTMENT LAYERS & COLOR CORRECTION (Raster Editing Fundamentals, Chapter 6)
   -> builds into COMPOSITING MULTIPLE IMAGES SEAMLESSLY (this course, Chapter 3)
   Fundamentals teaches adjustment layers for correcting one image's own color
   and tone. Chapter 3 applies that same skill to a harder problem: matching
   the color, lighting, and perspective of several different source images so
   they read as one believable scene once combined.

3. THE CLONE STAMP & HEALING TOOLS (Raster Editing Fundamentals, Chapter 7)
   -> builds into FREQUENCY SEPARATION (this course, Chapter 5)
   Fundamentals' Clone Stamp and Healing Brush fix a blemish by sampling
   nearby pixels directly, in one pass. Frequency separation is a more
   professional evolution of the same underlying goal (removing or smoothing
   an imperfection) - but it separates an image into a texture layer and a
   tone layer first, so texture (pores, fabric weave) can be preserved while
   tone (blotchiness, shadows) is smoothed independently, avoiding the
   "plastic" look a single-pass Clone Stamp/Heal pass can produce.

--------------------------------------------------------------------------
WHY THIS WORKS AS AN ANSWER:
Each pairing names a specific Fundamentals chapter and a specific chapter in
this course, and explains concretely - not just by assertion - how the
advanced technique is a genuine evolution of the more basic one, showing the
underlying skill actually being built upon rather than just restarted from
scratch.
