Accurate galaxy scaling relations are essential for a successful model of galaxy formation and evolution. Most of the measured photometric and structural parameters involved in these relations are affected by dust and inclination effects, which introduce biases and degeneracies. We present a detailed analysis of a sample of nearby spiral galaxies taken from the KINGFISH survey. The photometric parameters of the morphological components are obtained from bulge-disk decompositions, using GALFIT. Dust opacities are determined from a previously discovered relation by Grootes et al. (2013). The method and the library of numerical results from Pastrav et al. (2013a,b) are used to correct the measured parameters to intrinsic values. Measured (observed) and intrinsic (corrected) galaxy scaling relations are presented, in the optical regime. The main characteristics of the relations, the mean dust optical depth and dust/stellar mass ratios are in agreement with values found in other works.
