We present results of searches for new physics in final states
with photons at CDF in approximately 1 fb-1 of p anti-p collisions at
1.96 TeV. We give an overview of the data-driven photon background
estimation techniques used for the analyses. We report on a search
for diphoton peaks and signature-based searches for gamma gamma + X,
l gamma + X (X = e, mu, missing E(t), gamma) and t anti-t gamma.
