We study the DVCS amplitude within the color dipole approach. The light-cone
wave function of a real photon is evaluated in the instanton vacuum model. Our
parameter free calculations are able to describe H1 data, both the absolute
values and the t-dependences, at medium-high values of Q2. The Q2
dependence is found to be sensitive to the choice of the phenomenological cross
section fitted to DIS data.Comment: 11 pages; references added, bibliographic inaccuracy correcte
