For a sample of 16 Sb galaxies, disc scale lengths rD in B and I are investigated in order to study the dust content. The ratios rD(B)/rD(I) increase from 1.0 for face-on galaxies to 1.5 for edge-on galaxies. Scale length ratios derived from model images increase from face-on to edge-on view by ≤ 10% only, regardless of whether the model galaxies are optically thin or optically thick.
