Profiles of surface brightness, ellipticity and position angle
obtained from
CCD-BVRI images are presented for a sample of 14 spiral galaxies with
. For these galaxies, exponential disc
components were fitted to the profiles. A decrease of
disc scalelengths from B to I is found for 13
galaxies, while for
one galaxy scalelengths increase from B to I.
The scalelength ratios 
, 
and
show a systematic increase with increasing
apparent ellipticity.
The maximum variation is found for which is
larger for edge-on galaxies than for face-on galaxies.
Key words: galaxies: spiral / galaxies: photometry
