The ESSENCE project plans to discover and follow-up ˜200 Type Ia SNe over a redshift range z = 0.2-0.8 to measure the dark energy equation-of- state parameter, w, with a fractional uncertainty of 10 very accurate and well-calibrated photometry is necessary with particular attention to all possible sources of systematic error. We present here the detailed analysis and verification of our photometric pipeline, assessing for each reduction step its impact on the error budget of our photometry
