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.

Astronomers are making great efforts to achieve ambitious goals: identify sources from the Epoch of Reionization, discriminate between different mechanisms quenching star formation, describe the relationship between galaxies and their hosting halos, unveil the nature of Dark Energy…
\nA cornerstone in all these studies is the accurate estimate of galaxy redshifts and other physical properties (e.g. stellar mass, star formation history, structural parameters) from spectroscopic and/or photometric data.
\nIn turn, such scientific results will provide a solid physical background to improve the measurement techniques and explore new regions of the parameter space.

\nBuilding on a recent CANDELS workshop, this conference will examine key open issues in astrophysics and cosmology, discussing how the most advanced methods, applied to current and future datasets, shall contribute to solve them. To this purpose, we aim at gathering different astronomical communities: not only experts in galaxy measurements, but a diversity of observers and theoreticians whose work can be extremely beneficial to optimally extract information from photometric and spectroscopic surveys.
