The simple rule
If you want one palm reading photo, start with your dominant hand. For most people, that is the hand used to write, hold tools, or perform precise tasks. It is often interpreted as the hand of current habits and expressed choices.
The non-dominant hand is often read as baseline temperament, earlier patterns, or quieter tendencies.
Why both hands can help
Comparing hands can reveal contrast. One hand may show a clearer head line, while the other shows a stronger heart line. That does not mean one hand is true and the other is false. It gives two views of the same person.
For AI palm reading, both hands can be useful, but a single clear dominant-hand photo is a practical starting point.
Couple readings
For couple palm reading, consistency matters. If one person uploads a dominant hand, the other should do the same unless the flow asks otherwise. This keeps the comparison cleaner.
