Light speed clarification please?

Since light moves at a constant speed relative to any observer, is light then considered to be within the observer's inertial frame of reference when he or she measures or perceives it?

I just realized the error in my question, let me rethink this. Feel free to comment tho.

Rephrasing the question for clarification's sake: What exactly does SR say about a photon's inertial frame of reference relative to that of an observer who is stationary (in this case we'll define stationary as relative to the earth; ie, in a lab).

A photon's POV is not an inertial frame. Draw the lightcone.

I still don't understand the question. First, photon reference frames are non-inertial. And second, what do you mean, one reference frame relative to another?

I said "observer" not "another"... ie, the person measuring its speed.

...and if both are in constant relative motion, why is its frame not inertial?
