We compare the photometric accuracy of spectra and images
obtained with the {sl Ramaty High Energy Solar Spectroscopic
Imager (RHESSI)} spacecraft during the 2002-Feb-20 flare.
We measure the total photon flux in different spectral
energy ranges and compare it with the total photon flux
contained in images reconstructed with various algorithms,
such as {sl clean}, {sl pixon}, and {sl forward-fitting}.
We compare also the spectra of individual hard X-ray sources
in different imaging algorithms and discuss various background components and issues of image fidelity.
