Terms of Service

Last updated: July 26, 2026

Introduction

Welcome to PlateAndFilm (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at ambrotos.com and all associated calculators, guides, and services (collectively, the “Service”).

By accessing or using the Service, you agree to be bound by these Terms. If you disagree with any part of them, please do not use the Service.

Acceptance of Terms

By accessing, browsing, or using PlateAndFilm, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated by reference.

We may update these Terms at any time. Your continued use of the Service after changes are posted constitutes acceptance of the revised Terms.

Educational Aids — Not Safety, Conservation, or Appraisal Advice

PlateAndFilm’s calculators are learning and reference tools. They apply standard photographic formulas and simple ratio arithmetic to the values you enter, and round results for readability. The dilution and collodion ratio calculators perform math on ratios you already have from your own historical or manufacturer source — they do not supply chemical formulations, sourcing information, or handling instructions. Nothing on the Service is professional chemical-safety, conservation, appraisal, or historical-authentication advice. Working with historical photographic chemistry (including silver nitrate, collodion, and associated solvents) involves materials that can be flammable, toxic, or otherwise hazardous, and should only be undertaken with proper training, protective equipment, ventilation, and adherence to your local safety regulations. Before you rely on any result for coursework, a conservation project, a purchase decision, or any other purpose where accuracy matters, confirm it independently.

Description of Service

PlateAndFilm provides free, browser-based calculators and educational resources, including:

All tools are provided free of charge. We may modify, suspend, or discontinue any part of the Service at any time.

Your Responsibilities

When using the Service, you agree to:

You are responsible for exercising your own judgment and for confirming important results before relying on them.

Accuracy and Disclaimers

While we aim for correct formulas, we cannot guarantee that every calculation is error-free or suited to your circumstances. Results are estimates based on standard methods and the figures you provide, and are rounded for display. PlateAndFilm makes no warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, or non-infringement.

Intellectual Property

All content on this website — text, graphics, logos, tools, calculators, and software — is the property of PlateAndFilm or its content suppliers and is protected by applicable copyright and other laws. You may use the tools for personal and educational purposes; you may not copy, resell, or reverse engineer them, or remove proprietary notices.

Limitation of Liability

In no event shall PlateAndFilm or its suppliers be liable for any damages (including, without limitation, damaged materials, project errors, or other losses) arising out of your use of, or inability to use, the Service, even if we have been advised of the possibility of such damages.

Third-Party Links and Ads

The Service may link to third-party websites and displays third-party advertisements. We do not control and are not responsible for their content, and inclusion of a link or ad is not an endorsement. Your use of any third-party site is at your own risk.

Governing Law

These Terms are governed by and construed in accordance with the laws of the United States, and you submit to the exclusive jurisdiction of the courts located there.
