This would be for viewing on a monitor only, and I am limited to a 56K modem, so I would like a compressed JPEG file of around 50KB. In order to provide some consistancy in comparison, a full-frame 6cm by 6cm transparency (preferably Velvia) with a scanned image size of 360 pixels x 360 pixels would be good. I know that this is not a good scientific test for a hundred reasons, but I'm just looking for a rough idea of what quality I can get for posting photos on the internet. I am particularly interested in the following scanners: Epson 1640SU -- $399 US HP5370 -- $299 US UMAX Powerlook III -- around $1100 US bundled with Photoshop 5.5. -Fritz Olenberger ------------------------------ Date: Sun, 12 Nov 2000 10:56:09 -0800 From: Mark Rabiner To: hasselblad@kelvin.net Subject: Re: MF film scanners Message-ID: <3A0EE7C8.C1683238@rabiner.cncoffice.com> olenberger wrote: > > I am interested in seeing the quality produced by various medium-format > > UMAX Powerlook III -- around $1100 US bundled with Photoshop 5.5. > > -Fritz Olenberger > I've been using a UMAX PowerLook III for my Hassy and Rolleiflex negs and 4x5 and old snapshots from the 30's and love the darn thing!

It also says that they used 70mm film. Does anyone knows which film(s)?

I couldn't be happier with the results I'm getting with this combination. The original scan is several megs in size; the reduction I've posted can't do justice to the detail I can capture. I've had excellent luck picking out blades of grass in shots around my yard. BTW, the shot was made with a 501CW with 150mm Sonnar, one umbrella to the left of the camera, one for background and one for fill. Used Vivitar 283 and and 285 and I think a Pentax flash, all on peanut slaves. Cleaned up and cropped with Photoshop. My HP Deskjet 952C produces stunning 8x10s, if I use the HP photo paper. The subjects are my son and his girlfriend. http://testdocs.dced.state.ut.us/djtest/jen_jer_small.jpg ----- Original Message ----- From: olenberger To: Sent: Sunday, November 12, 2000 10:26 PM Subject: MF film scanners > I am interested in seeing the quality produced by various medium-format > scanners, and would be most grateful if anyone could sent me an image file > from their scanner (or refer me to a URL where it is posted).

I have used one of the old style finders and find the screen corners are often blurry when the center is sharp. Is the new finder better? I have a chance to get a new style finder at a good price. Any information would be greatly appreciated. Jim Laird ------------------------------ Date: Mon, 13 Nov 2000 10:52:28 -0800 From: "olenberger" To: , Subject: Re: Filter Factor for Linear Polarizer Message-ID: <000b01c04da2$e0e1a9a0$c8a91f3f@default> This means that the light is reduced by a factor of 3. This is really the filter factor, which translates to one and a half stops (1.585 stops, to be exact). A factor of 2 (one-half the light) would be one stop, a factor of 4 would be two stops, and a factor of 8 would be 3 stops. In general, the filter factor is the number 2 raised to the power of s, where s is the number of stops. Conversely, you can determine the number of stops from the filter factor by the formula s=log(f)/log(2)=log(f)/0.30103. Substituting a filter factor of three into the above equation, you get 1.585 stops. Since the Zeiss lenses only have detents at half-stops, they rounded off to 1.5 stops. -Fritz ----- Original Message ----- From: "Peter Shier" To: Sent: Sunday, November 12, 2000 7:27 PM Subject: RE: Filter Factor for Linear Polarizer > Yes it is a Hasselblad.
