Yes! - that is chromatic abberation compounded by lens flare. > And that cameras that are prone to c.a. like the Olympus C5050Z could benefit > from the addition of a UV filter ? No, chromatic aberration affects all lenses, and wide-angle-zoom lenses especially, although some lenses (usually expensive) are better than others. A UV filter cuts down haze and flare, and combined with a properly matted lenshood, will dramatically increase lens performance. It does NOT control chromatic abberation. BTW, it is essential to use a lenshood, even on flat overcast days. best William Curwen www.william.ws > TIA, > Andre > > From: "Shangara Singh" > Sent: Saturday, February 15, 2003 1:07 AM > Subject: Re: [PRODIG] D100 how big has anyone gone and what is fringing > please > > >> On 14/2/03 5:51 pm, rob wilkinson wrote: >> >>>> I also shot some signs last week and got a blue line next to a sign. > The >>>> light was coming from behind, is that called fringing ????. >>> I'm afraid it sounds like it. >>> cheers >>> Rob. >> >> Fringing can be rained back and some blooming too by using a UV filter >> (although, I thought, today's lenses had good anti-UV coating), it seems. >> You can use Panorama Tools to control the fringing.
