I'm cleaning out some things and also debating on whether to fully divest of my darkroom equipment, 4x5 camera, gear and lenses now that I haven't done any film work in some time. Until I stopped...

Hi Dean,
I also acquired my Howtek 4500 from Michael and like you found the experience to be first class all the way.

I use both PC and macOS (running in VMWare on my imaging workstation Windows...

I don't know if this will help (I know, it is really frustrating to keep hearing that :mad:) but here is the full sequence my 4500 goes through when I start a Preview scan. NOTE: This is using DPL...

As was suggested over on the ScanHi-End group from your cross post there, I also think there could be electrolytics that are either failed or getting close to failed. Now that you have your machine...

My first reaction is that the "flare" looks to me like tape (or possibly tape residue) on the negative, especially since I see it in both horizontal and vertical on the negative outside the image...

Just to be clear, my developing results mentioned in my original post occurred AFTER I encountered and corrected the problem with my expired package of XTOL. All of my results mentioned here were...

Thanks Bruce, Pere and everyone else for your suggestions and observations. Very interesting discussion.

Pere, you had asked earlier in the thread if somehow I was exhausting the developer by not...

Hi all,

I've been developing TMX 4x5 negatives (using EI 64) in my Jobo CPP-2 for quite a while, but based on a recent review of some past threads here I have decided to completely revisit my...

Good point about minimizing vibrations to help reduce the possibility of connections problems. After I first acquired my SM4500 I was amazed at how much it vibrated laterally when doing previews,...

Aside from the question of which inks are being used by these "best B&W digital printers", I also wonder if they are even using Epson printers, and if so, are they doing their work with ABW or with...

With this new FST data my guess is either a bad High Voltage Power Supply (HVPS) for the green PMT or possibly a bad VDC (Video Digital Controller) board. This is just based on my reading of various...

Tyler,

Any chance that quality of AC power to the scanner has changed? Have you recently moved the unit to a different outlet or changed the power cable? Do you have the unit on a UPS that...

FWIW, I am dubious about chasing SCSI problems at this point, based on the available information. If the machine were giving random errors at different times, or even the same error at different...

Tyler,

The IEC board is the "Image Enhancement Controller" (also known as the CosMYK board). It provides the capability for CMYK conversion and sharpening on the fly. My guess is that this...

A quick further update in case anyone is following my experience with DPL 8.0: I've now received a fix from Evan at Aztek that resolves the issue I was having with doing a 4000dpi scan on my Howtek...

My 29160N SCSI card was running BIOS v2.57.2 when I first received it. As part of my recent testing and investigation I installed BIOS v3.10.0 which is the latest available from Adaptec. The main...

A quick update: The 4500 is just fine. I setup a dual-boot environment on my machine and installed Windows 7 32-bit on an extra disk in the system. I downloaded a demo copy of Silverfast 6.6Ai for...

Hi Adam,

Yes, I'm aware that the 4500 is limited in hardware to 12 bits per pixel per color. However this does not (should not) prevent the software (DPL in this case) from saving a scan as a...

Glad you asked. I've been contemplating a message here to the group and your question now gives me a reason to post. Like you, I am very interested to hear from anyone else running DPL 8.0 on...

Bob, thanks for your information. Yes, I'd definitely be interested in knowing what this lens was selling for when new. Looking forward to your update when you have a chance.

Thanks,
Dave

Hi everyone,

I'm finally getting around to liquidating some of my darkroom equipment which I am no longer using and have a mint Rodenstock Apo Rodagon N 150mm/f4 enlarging lens (Serial 10981734)...

Not only are there no pins, there are no holes either in the bellows frame. And my camera does not have "L" clips at the bottom and sliding clips at the top on the front standard. At the bottom...

This is definitely a Zone VI bag bellows (well, at least this is how it was advertised by the B&H Photo Used department)...both frames of the bellows perfectly mate to my camera. The only thing...

I've had my Zone VI 4x5 since 1989 (Serial 1251) and I've made many fine photographs with it. Lately I've acquired a used Fuji SWD 90 mm 5.6 lens. The rear element of the 90mm lens will not fit...
