*Finite-t and Target Mass Corrections in Deeply Virtual Compton Scattering*

I present an approach to calculate 'kinematic' power corrections to 
DVCS. Topics covered are:
1) Rigorous separation of 'kinematic' and 'dynamic' higher-twists
2) Technique to calculate LO contributions based on conformal symmetry
3) Gauge and translation invariance
4) QCD factorization of kinematic power corrections to twist-4 accuracy
5) Numerical estimates for the size of such corrections in helicity 
amplitudes and (preliminary) Compton
   form factors
