The spectral separation you are seeing in the multicoloured light, is from a multicoloured light! That was the source of the coloured blobs that are whizzing across the walls of the bowling alley. The slow shutter speed ensured they moved during the exposure. :-) Rick On 16/11/2005, at 6:34 AM, John Black wrote: > > > > >> >> My daughter was about ready for the party food I think. >> >> Leica MP, Noctilux, f1, 1/15th, Velvia 100F. >> >> http://members.dodo.com.au/rdcb37/bowling.jpg >> >> >> > > Shooting with a Noctilux wide open gives really bizarre point > source light > aberrations around the outside of the composition.
