Fixative of choice for tissue photography

Explanation:
Mercuric chloride fixatives are favored for tissue photography because they provide strong, rapid cross-linking of proteins that preserves fine cellular and nuclear detail with minimal artifacts. This results in crisp nuclear outlines and overall morphology that photograph well under standard stains, yielding high-contrast, reproducible images. Historically used in fixatives like B-5 and Helly’s, they give superior photographic quality by maintaining color and structure more faithfully than many other fixatives, which can cause color shifts, shrinkage, or loss of delicate detail.
