Hi,
It depends on your own "feel" for them.
Reversals for me do not change meanings completely, sometimes they reveal the person's own energy. For instance, if all cards are reversed in a reading, it shows a depressed, or pessimistic person. But this is my own interpretation. Everyone uses them differently.
Sometimes reversals show me that I need to pay closer attention to a specific card. Or even that a positive qualitity or potential is not being applied or used by the person.
Also, each card has a positive and less positive side to it, and the reversal makes me think of a meaning that is closer to the less positive side of the card....
I must sound confusing... I know...
