OK reading through this, I can help a bit, since I have the Epson 3200 which is the precursor to the 4870.
Couple of assumptions first:
1. Silver Fast launches when you do File->Import->Epson 4870?
2. For B&W negatives you are choosing the 8-bit or 16-bit grey scale option?
3. I would use 400dpi max - many people use 150dpi or 300dpi.
4. I would not scan in to original. I have a 'custom' image size of 10" x 10" since, my Blad makes squares.
5. I also scan in one image at a time versus batching.
6. I always preview, 'square' my image and zoom. Then I re-size/crop the preview and zoom again.
7. I use levels to make any adjustments and I make any necessary colour adjustments with either curves or levels.
8. I turn ON unsharp mask.
9. I set the ICC profile to Adobe RGB for colour and Gamma 2.2 for B&W.
Oops, one more assumption:
10. I don't know which 4870 you have the PHOTO version or the PRO version. If you have the PRO version, I would assume that you used the target and the calibration software to create a custom ICC profile?
Once in Photoshop, I then see if I need to make any further adjustments and if so, I scan again. I prefer to have a 'good' scan before I start with any PS.
Hope this helps a bit.
I recomed to first scan a grey card
Hi I hope this helps you
1, scan a gray card that way you have a know value.
2 scan a grey card same reason as before
Now you play with the scanning software settings so that you get the corrected values
3 scan a neg and adjust to find your black and white points
or even better scan your neg and a grey card together that way you have a set point to shoot at and GO BY THE HISTOGRAM not what the scan looks like, Then you can play with it on PSD (photoshop) adjustment layer curvs
if you need more help let us know
One thing I've found about unsharp mask and grain is the radius needs to be a bit bigger than the grain size or it will enhance the grain instead of the image. A little careful experimentation will tell you what to set it at for each type of film and ppi.
I have found that when I scan B&W negs I have to turn OFF pixel polish (makes old negs look new) and dust busters (my scanner thinks the grain is dust and makes the scan very unsharp. Then I scan a raw, non-manipulated neg.
I also have the 4870 (photo version, not pro). I was told to not use ICE when doing B&W because it increases the grain. Also, I scan from the scanner software itself, not PS CS or elements. At the top, there's a pull-down where you can select auto, home, or pro mode. With pro mode there are more options for resolution, size, and pretty much everything else. I've created fullframe profiles for 35mm and 120 using the customize selection at the bottom of the list under scanned size (I think that's what it's called). I've done a lot of adjustments in setting things up, but you can save ones you've created, so it gets faster. I also usually scan at about 350 dpi with the size set for around 8 x 12. That way, I should be able get a decent print without killing my harddrive. HTH!!

Thanks for everyone input again. What would I do without you guys???
Winger, can I ask how you scan your 120's as I can't seem to get mine to scan 6 negs at a time, as it advertises that it does.

My biggest problem with the scanner so far is that it doesn't always read the edges of the frames accurately and then won't give thumbnail views. Is that what's happening to you as far as not getting 6 negs? If you're in thumbnail view, you do have remember to adjust the settings for each frame separately and make sure each box is checked. If all the thumbnails don't show on the screen, it probably isn't reading them all. If you choose "normal" in the preview mode, it'll show everything on the bed. That's what I keep having to do but it is a bit more of a pain to select the frames. I've only had my scanner for a couple of months, so I haven't gotten it all figured out, yet. HTH
Thanks Bethe. I can't seem to scan any more than 1 negative at a time as all the other negs get the left & right edges cropped by about 1/3, so not much left of the image. I guess I just can't seem to get out of the 35mm size to change to a 6x6 size.
So Bethe I'm sorry I can't give you any advice at all as yet as I can't get one right.
Could you explain to me how to change the size to 6x6 as it always reverts back to 35mm on me.
I'm doing this from memory, so I hope I get it right. At the top of the scanning software, there's a pull-down box where you can select "professional mode". Once you do that, the rest of the window has more options. Somewhere beneath resolution, there are boxes for size of thing being scanned and size of result. The default for result is "original". If you click the arrow by that, there's a long list, at the bottom of which is "customize". Choose that, put in say, 8 inches by 8 inches, write over what's in the box at the top (it's 2 words, but I can't remember them, I called mine "Hassie") and click save. It took me a few tries to get it right, btw. Then, when you go back to the main one and click the arrow by original, the list will include whatever you've named your square one. Once the marquee is on the photo you're doing, you can drag the edges to make it bigger and move it around with the hand. If this still doesn't help, maybe I can figure out how to copy screen shots into an e-mail or PM. just let me know. And I'm far from an expert in it, I just fiddle around until I figure out something.
I had an Epson 1200 "perfection" 3 generations before yours Nicole; which I had difficulty getting good results from using the Epson scanner software. Grain seemed to be enhanced by the Epson USM being enabled.
By switching to Vuescan at www.hamrick.com (full free working demo downloadable) I reckon that I doubled the performance of this scanner. At $99 for pro-version you get unlimited upgrades and the ability to fully colour manage, it works for just about any scanner worth its salt. It is fully transferable should you change scanners in the future. I like the ability to save set-ups that you use often. These can be easily amended if necessary. It is not everyone's cup of tea, since you add numbers to boxes rather than use a more graphical interface. Suggest a Google search on Vuescan to get other testimonies. The Help manual could do with improvement, but it is worth persisting with.
Personally although I tried hard with Silverfast, even reading all 380 pages in the manual(and still not winning the anorak!) I felt it lacked the control I was able to get with Vuescan. That said, there are many serious affictionados of Silverfast who get great results.
Vuescan has a batch option where you can calibrate for filmbase+fog to get everything optimised for that film. I only ever scan one shot at a time.
Try misaligning the shot on purpose for the preview if the rebate not visible in the holder. This enables you to sample from the rebate to set a true black point. Ensure white point is not burning out.
Concur using 16 bit.
You will need to "capture sharpen" which is only a tiny amount. Use Photoshop or plug-ins available for this since you have more control. Other sharpening takes place prior to output.
This is a huge subject please forgive my brevity.
I realise that I forgot to mention two salient points for justifying my claim to double performance.
First - Multi-sampling where the scan does the number of passes you choose (I found 3 fine) it then averages readings which significantly reduces noise in the shadows and extracts better shadow detail, yielding an effective increase in DMax.
Secondly - ability to save the RAW files separately which can be reprocessed in Photoshop should the need arise, without the hassle of mounting and physically scanning the negs again.
Finally, I was able to do ICC calibration with an IT8 target to enable far better colour accuracy with tranny films.
I read somewhere that either ICE or GEM doesn't like silver in films which is why it doesn't work with B+W films other than XP2 etc.
Hope this was helpful.
