| Abstract: | We present new results obtained when using clusters of galaxies as gravitational lenses to build up an independent sample
of galaxies with z ≳ 2. The amplification effect provides a tool to study the spectrophotometric and morphological properties
of such galaxies 1 to 3 mag. deeper with respect to field surveys. Distant sources are selected close to the critical lines
in clusters where the mass distribution is well known, using photometric redshifts computed on a large wavelength interval.
This method allows to reduce the biases towards luminous and active star-forming objects.
