We present for the first time CCD SDSS gr photometry, obtained at the GeminiSouth telescope with the GMOS attached, of stars in the field of the poorlystudied star clusters NGC1768, HS85, SL676, NGC2107, NGC2190, and SL866, whichare distributed in the main body of the Large Magellanic Cloud. We applied asubtraction procedure to statistically clean the cluster CMDs from field starcontamination. In order to disentangle cluster features from those belonging totheir surrounding fields, we applied a subtraction procedure which makes use ofvariable cells to reproduce the field star Color-Magnitude Diagrams (CMDs) asclosely as possible. We then traced their stellar density radial profiles fromstar counts performed over the cleaned field stars dataset and derived theirradii. Using the cleaned cluster CMDs, we estimated ages and metallicities frommatching theoretical isochrones computed for the SDSS system. The studied starclusters have ages from 0.1 up to 2.0 Gyr and are of slightly metal-poor metalcontent ([Fe/H] ~ -0.4 dex).
