Based on the information in the tweet conversation, it seems there's a discussion about using someone's artwork without permission, where one person believes they were showing appreciation while the other is asserting creator rights.

Fair use is a legal doctrine that allows limited use of copyrighted material without permission under certain circumstances. It's part of US copyright law and applies to various activities, including in the visual arts community.

For visual art specifically, fair use considerations include:

1. The purpose and character of the use - whether it's transformative by adding new meaning or expression rather than simply reproducing the original work.

2. The effect on the potential market for the original work - whether your use might deprive the copyright owner of income or undermine potential markets for the work.

In practice, fair use has some important limitations:
- The use of the copyrighted work should be justified by a specific objective
- The user's objective should predominate over merely representing the work
- The amount used should not exceed what's appropriate for your purpose
- Attribution should be provided as customarily expected in the field

Even if you intended to show appreciation for an artwork, using it without permission may not qualify as fair use if you're simply reproducing it without adding new meaning or if it potentially impacts the creator's market for their work.

Many creators and institutions have specific policies about reproduction of their works. If you wish to use someone's artwork, the safest approach is to request permission directly from the creator rather than assuming fair use applies.

I don't know the specific details of your situation, but respecting both the creator's rights and perspective on their own work is important in artistic communities.

@@o3 would using ai to make a piece of art more "realistic" eg. making a drawing take photo-realistic form be considered fair use

Short answer
“I turned someone else’s drawing into a photorealistic version with an AI filter” is not automatically fair use. In many situations it will be treated as a derivative work that still requires the copyright owner’s permission. Whether it qualifies as fair use depends on how the four statutory factors line up in the specific case.

Why it may fail the fair-use test
1. Purpose and character of the use
• You are copying the entire expressive content (characters, composition, color choices, etc.) and merely re-rendering it at higher fidelity. Courts tend to see that as stylistic, not transformative.
• After the 2023 Supreme Court decision in Andy Warhol Found. v. Goldsmith, simply changing the style or medium (e.g., cartoon → photo) often is not enough to count as transformative.

2. Nature of the original work
• Drawings are creative works at the core of copyright protection. That factor tilts against fair use.

3. Amount and substantiality
• If the AI model ingests the whole image and reproduces every key element, you have copied the “heart” of the work. That weighs against fair use.

4. Effect on the potential market
• A photo-realistic version could substitute for or dilute the market for licensed derivatives such as prints, posters, or adaptations. Any realistic possibility of lost licensing revenue weighs against fair use.

When it might edge closer to fair use
• You add substantial new meaning or commentary—e.g., the photorealistic rendering is used to parody the original or to critique a broader social issue.
• The original art is only one small element in a larger collage or multimedia piece in which your creative contribution clearly dominates.
• You limit distribution to a narrow educational or research context with no commercial impact.

Derivative-work rights still apply
Even a highly transformative derivative can infringe if it is built on the protected expression of the original work. Fair use is an affirmative defense, not a guaranteed blanket exception. The safest route is always to license the underlying artwork or create your own base drawing.

Practical tips
• Ask for permission if possible; many artists are open to collaborating.
• If you choose to rely on fair use, keep documentation of your purpose, process, and the differences you added.
• Avoid commercial exploitation until you are certain about your legal footing.
