Re: filmscanners: RE: filmscanners: image samples of digital artifacts
Well, this may be what Dan Honemann is up against on his notebook computer. I told him to ditch it. That's a little extreme, Rafe. :-) Granted that an LCD is not suited to *working* on graphics, it's viable for *viewing* them. Still, if Dan throws out his Dell Inspiron, I hope he throws it in my direction--I could use a portable backup, and could keep up with the List while I'm fishing or on vacation. g Best regards--LRA From: rafeb [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: filmscanners: RE: filmscanners: image samples of digital artifacts Date: Thu, 19 Jul 2001 23:23:43 -0400 At 11:33 AM 7/20/01 +1000, Rob wrote: Rafe wrote: I'm willing to bet that Dan Honemann has his video set to 256 colors (indexed color.)

If I had a website, I'd give it a go (I've got *plenty* of examples!)-- maybe some kind-sprited, web-savvy member will do it? I'd be happy to put things online provided the examples are appropriately sized. I already have a page about scanning to explain the work which was being done on looking at film types. It would be good to have examples of things which are problematic about scanning. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

Is this what is called jaggies? Do they show up in prints? You need more colours. This looks fine in 24bit on my work computer. You may be running less than 24bit colour. Depending on the OS some video drivers don't display a full palette of 24bit colour even though the driver claims to be set to it. So no, it's not jaggies exactly - it's your video card dithering the colours down to what fits in your palette. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com

Dan wrote: It was set to 16-bit (True Color), so I changed it to 24-bit (High Color) and rebooted. Still see the lines in the sky, but this is only a Dell Inspiron 3500 notebook PC with a NeoMagic MagicMedia 256AV card and a 14 LCD screen. No doubt something in that mix isn't up to snuff. Try hooking up a proper monitor. The LCD is probably very limited in the number of colours it can display. Rob Rob Geraghty [EMAIL PROTECTED] http://wordweb.com
