Include your CV.
Put your most recent events first. Remember this is NOT the same kind of C.V. as one you would design for a job.
Include any 'jobs' in a short paragraph, perhaps to indicate the way you
a) work and relate to other people.
b) are a hard worker.
c) have particular skills, relevant to the gallery submission.
Don't include uneccessary details such as marital status.
Do include things like B.A. (Hons), or M.A., or any specific academic awards that you achieved when you were a student, or since.
include an S.A.E. - for the return of your images. This is good manners, and should ensure their return.
