Re: filmscanners: Nikon MF LED light source...

Well, Rick Boden just found a camera board for $800. But he'd been holding
out for months/years because erstwhile the price had been $1700 from Creo.
Plus RT shipping, if a given user isn't capable of making the repair
himself. 

The estimate to repair my scanners problem was $800. But with RT shipping
that's $1200. Rich for my blood.

Austin, I'll short cut here. You yourself have already gone to what appears
to be great effort because *you* want to rewrite the driver.

That's not what I was told by Rick at leaf. Not for the metal case design. I
said older models.

Austin, if I'm not mistaken, you are on the Leafscan list aren't you? Did
you ever look at the files Andrew Cassino posted to the files section of
Leafscan?

And when I was talking about the softness of the red channel, and asked
twice, with a chime from another member too, for other list members (of
which there are 100) speak out if their red channels were anywhere near as
sharp as their others, not a one spoke up.

When people post samples of their Nikons, Imacons, and Polaroids, I check
the channels. The red channel is invariably sharper than mine. I know mine
is in for a $400 shipping charge for repair, before we start itemising parts
and labor.

So when you say only slide film, you mean to suggest that color negative s
don't require three passes? That's where the triple scan time comes from.

It doubles scan times in my experience. The progress window says it'll take
about 10+ minutes for an HDR grayscale, but it takes 15-20.

If I felt like you do about my Leaf my wife would shoot me, and I'd be
expecting baby Leafs soon.

Austin I can only suggest that the opportunities I take to dis the Leaf are
only as annoying to you, as your chest puffing comments about the Leaf are
to every one else. Okay, can't speak for every one else - annoying to me.

Austin, you responded to his post on the Leafscan list about it. I cant help
you if you have selective memory.

It says you *may* use minimum. It's a ten year old document, based on ten
year old materials. But if it works for you I'm pleased. I already said I
should test it more thoroughly.

I'm starting to see how you relate to the world. Very little scientific
objectivity. Heavy bias based on what's necessary for you.

Austin, I'm only talking about my experience with my scanner. It's not your
sister I'm talking about. Cool it.

All this started when you compared your scan time with the Nikons, and I
made a short quip intended to show I didn't consider it an valid comparison
because of differing resolutions, and later, the possibility of different
quality modes.

Why does this get so intense for you?

Look, this is unhealthy, lets put it to bed. Have the last say.
