In the descriptions for Photon Mode and Graviton Mode on p102 of the CRB, it says that when you enter those modes you become "photon-attuned" and "graviton-attuned".
Some of the later Stellar Revelations (e.g. Wormholes, p107) explicitly say that they require the PC to be graviton-attuned. (Others explicitly require photon-attuement.)
Some of the earlier Revelations, though, just seem to require attunement to either mode. The language used is generally "when you are attuned or fully attuned...", and does not specify a mode.
Does this therefore mean you can use the "attuned" aspects of these Revelations, no matter which mode you are in?
For example, you could therefore be graviton-attuned and use the extra bull-rush element of the Stellar Rush Photon Revelation (p104-105).
Am I understanding this correctly?
