Re: Out, out, dan spot!
Those were the days, eh? When all we had to worry about was the Scheimpflug principle. How we skipped and jumped and laughed! Anyway, that diffraction thing is easily solved if you ask me - just develop a sensor which only captures light when it’s behaving as a particle, then there’d be no diffraction. > On 30 Aug 2022, at 17:17, Bill wrote: > > Refraction is a big problem for pixel peepers, not so much for the rest of > us. > We never saw it as a problem on film because we weren't blowing things up > to 4x6 feet and then inspecting the image from 4 inches. > > bill > >> On Mon., Aug. 29, 2022, 10:08 p.m. Alan C, wrote: >> >> Refraction? >> >> https://photographylife.com/what-is-diffraction-in-photography >> >> Alan C >> >>> On 28-Aug-22 02:21 PM, coll...@brendemuehl.net wrote: >>> If at f/18 there’s a soft shadows spot (several) but none at f/5.6 then >> I’m wondering about sensors. >>> >>> Seems to be a common situation. >>> >>> Never had that issue with film. ;-) >>> -- >>> %( -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
Re: Out, out, dan spot!
Refraction is a big problem for pixel peepers, not so much for the rest of us. We never saw it as a problem on film because we weren't blowing things up to 4x6 feet and then inspecting the image from 4 inches. bill On Mon., Aug. 29, 2022, 10:08 p.m. Alan C, wrote: > Refraction? > > https://photographylife.com/what-is-diffraction-in-photography > > Alan C > > On 28-Aug-22 02:21 PM, coll...@brendemuehl.net wrote: > > If at f/18 there’s a soft shadows spot (several) but none at f/5.6 then > I’m wondering about sensors. > > > > Seems to be a common situation. > > > > Never had that issue with film. ;-) > > -- > > %(real_name)s Pentax-Discuss Mail List > > To unsubscribe send an email to pdml-le...@pdml.net > > to UNSUBSCRIBE from the PDML, please visit the link directly above and > follow the directions. > -- > %(real_name)s Pentax-Discuss Mail List > To unsubscribe send an email to pdml-le...@pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and > follow the directions. -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to pdml-le...@pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
