Challenge 2: Why the Color Correction Request Is Easy to Fulfill — Solution Walkthrough

Why this request is easy given how the workflow was structured:

Step 5 applied the color correction as a Curves Adjustment Layer,
per Chapter 6's own material — a non-destructive adjustment that sits
above the image, fully editable at any later point, rather than a
direct adjustment that permanently alters the underlying pixel data.

Why this specifically makes the client's request simple:

Because the working PSD/XCF file (Chapter 9) was preserved with every
layer intact, including that Curves Adjustment Layer, the correction
can simply be reopened and its own settings adjusted directly — no
need to undo later steps, redo the color correction from scratch, or
guess at what the original correction even was, since the adjustment
itself, not just its baked-in result, is still sitting right there in
the layer stack.

What would have made this request difficult instead:

If the color correction had been applied as a direct adjustment
(Chapter 6's own contrasting example) rather than an Adjustment Layer,
or if the working file had been flattened at any point (Chapter 4/9's
own warning), adjusting just that one earlier correction would require
either starting over or attempting to approximate the original
adjustment's effect on top of an already-altered image — a
meaningfully harder, less precise task.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise connects Chapter 6's own Adjustment Layer material and
Chapter 9's own preserved-working-file material to a realistic later
revision request, correctly explaining why the capstone's own
structure specifically enabled an easy fix.
