We present for the first time CCD SDSS gr photometry , obtained at the Gemini South telescope with the GMOS attached , of stars in the field of the poorly studied star clusters NGC 1768 , HS 85 , SL 676 , NGC 2107 , NGC 2190 , and SL 866 , which are distributed in the main body of the Large Magellanic Cloud . We applied a subtraction procedure to statistically clean the cluster CMDs from field star contamination . In order to disentangle cluster features from those belonging to their surrounding fields , we applied a subtraction procedure which makes use of variable cells to reproduce the field star Color-Magnitude Diagrams ( CMDs ) as closely as possible . We then traced their stellar density radial profiles from star counts performed over the cleaned field stars dataset and derived their radii . Using the cleaned cluster CMDs , we estimated ages and metallicities from matching theoretical isochrones computed for the SDSS system . The studied star clusters have ages from 0.1 up to 2.0 Gyr and are of slightly metal-poor metal content ( [ Fe/H ] \approx -0.4 dex ) .
