Default Help with noise reduction of slide scans

Is there anyone here that may have some tips on noise reduction after scanning slides? Seems, I get a lot of grain when I scan. I apply noise reduction, and a lot of times it gets to the point of being blurry. Is there some way of scanning a slide, sharpening it, and not coming up with so much grain. I can see a lot of tiny little circles after doing this. Is there some way to avoid this.

I tried with scanning this slide, and this was the result.

I rescanned and tried it again, but doesn't look much different. I seem to be having this problem with most of my scans lately.

How are you scanning? What scanner? what resolution? Also, what film type and speed are you scanning here?

I'm using a Minolta, Dimage Scan Dual III. I'm scanning as a tif at the highest resolution. I think the film is a Kodachrome 64.

All the scanning options on the scanner are turned off. I then process using PS CS3.

Thanks Charles, I forgot that I had that program. I ran it through, but I'm not sure If I did it correctly. Here is my sample. Opinions?

I have to admit it looks soft to me.

I have had even NeatImage over blur when a slide was dark and a touch soft to begin with.

But, Kodachrome at night is actually just going to be very hard. Kodachrome had so little range, and if you try to adjust for that, you get weird results sometimes.

Maybe playing with the Neat Image to do a less severe noise scrub?

Yeah, I kinda thought it was on the soft side too. I'll redo it and resubmit it in the morning. I'll see what happens. Thanks.

I find that 9 out of 10 times NeatImage will do a much better job removing grain than my regular program.

On that tenth slide, it will turn it into a mess.

Hope I didn't misdirect you on this one.

No Charles, You didn't misdirect me. You gave me the answer I needed and I appreciate that. You've been a great help in the past too.

Anyway, my resubmission failed as it got PEQ'd. I think I'll print a copy and maybe frame it so I can hang it on the wall. After all it was sort of a twilight of the Santa Fe. Just a personal thing.

I forgot to mention that the quarry belonged to Vulcan Materials. It was a neat operation by itself, as they supplied a lot of ballast for the Santa Fe. They had a number of locomotives there too.

It's all gone now. so I guess it would be a twilight of Vulcan Materials as well.

To be honest with you, I just don't see this on Railpictures.

-I don't see a train, I see a sunset.

Sorry. But then again; 13 years old here and I only have 4 photos on.

It's just that I've never seen anything like this before.

Well, the degree of train in a train shot is very much a matter of ongoing debate. Just poke around, youngster! , and see what is here.

Seriously, here are a few to get you started. The last is the "three points of light" shot discussed in these forums some time ago.

That's one neat looking operation. Reminds me of science fiction movies. Thanks for sharing. Sorry I never saw that.
