Hello,
I ask myself questions, I have a reflecta rps 10m, is it on vuescan the autofocus it is always on or preview does it change something ? Thanks
Sorry for my bad english, im french
I note that you say this should only need to be done once per batch. But what if thereās different exposures within the batch (not sure if that makes any sense?) Also does it make a difference? Because Iāve scanned like 100 already and each scan Iāve been locking the exposure again, I imagine itās okay as my negatives turned out fine when converting. I use a plustek 8100 if that helps
Thanks,
Liam
Itās OK if some shots are more dense than others in the rollā¦ itās still good practice to keep the same exposure when you digitize a roll, because small variances in digitization exposure can make it more difficult to edit photos as a group laterā¦ for instance, it can throw off the āsync sceneā, and potentially throw off future group analysis functions.
So for example if I over expose by 1 stop. Sometimes when I did the preview, a shot would have exposure at 2.132 for example but another may be up at 3
For my next scan Iāll do it all with a locked exposure and see what I get 
Nate. Iām using Vuescan with a Plustek 8200i. Iām seeing a couple of issues with this guide and my set up:
First is that by selecting image as the media, the preview does not invert it so Iām just looking at the negative throughout the process. Iām guessing this is not an issue for the final scan but it is still a little annoying because I would like to be able to judge whether I actually want to do a full scan or not. And that is difficult based on looking at an orange negative.
2nd is setting bits per pixel to auto. With my plustek this does not seem to then allow infared cleaning. Like it seems to set this by auto to 48 bit RGB. If I want ir cleaning then I need to specifically set this to 64 bit RGBI.
Thirdly is the IR cleaning itself. I set it to medium. I can see that it has removed dust spots etc within the preview. I have Raw output set to save. Upon import into Lightroom though I can see that the IR cleaning has NOT been saved into the DNG as you say in the guide. Any thoughts on this? From what I have read on the subject in Vuescan bible and elsewhere, in order to have IR cleaning you have to have the output set to 64 bit RGBI.
Im having the exact same issue. Just realised that with my Plustek 8200, dust detection works in the preview when the scan has completed, but has not been applied to the DNG. Followed every setting in the tutorial. Any solutions yet? Should I just email vuescan?

Iām having a problem importing the RAW DNG into Lightroom. Iām getting an error that says āThis file uses an unsupported color modeā
I also tried to scan it as a TIFF DNG, but I couldnāt even find the saved file after VueScan exported itā¦
Hmmā¦ Make sure that you are following the output settings in Vuescan exactly as shown in the guide - especially setting the āRaw File Typeā to ā48 bit RGBā

Hi,
Did you have any joy with finding out if there was a solution?
I have tried emailing Vuescan but sadly Ed Hamrick is crazy rude and super unhelpful so I didnāt get very far.
Are you on the latest version of VueScan? I just picked up an 8200i and itās IR is working on VueScan
With that said, the removal isnāt greatā¦
Are you sure itās not applying? Iāve just gone a bit ham with testing, I have noticed that it does work, but really badly. If I scan in Silverfast 99% of the dust is gone, but in VueScan, even on heavy thereās still a lot there. I think itās either an issue in VueScan or that VueScan just isnāt getting on well with the 8200i
Just started using NLB 2.1, scanning with VueScan and following this guide (on a Coolscan 9000).
Iām getting a lot more grain than when I scan the same image as a linear TIFF of equal settings.
This is brand new Portra 800, not pushed. Scanned at 2000dpi, RAW DNG, 48bit RGB, Medium IR clean, grain reduction none. NLB 2.1 was set to Vuescan DNG, Frontier. Autocolor 2.0 Neutral
Any tips?
Thanks in advance.
Iām on the latest vuescan so no problem there. IR cleaning is working at the preview stage. Itās just not then being saved after full scan and save.
What options do you have set?
Skipping a few such as lock exposure, I have:
Input - 64 bit rgbi
Output - 48 bit rgb - Raw output with save
Iām using the same settings as the guide so I have the bits per pixel on auto
I am also using lock exposure
For me, at least, it does save the IR cleaning, but itās very very bad, especially compared to Silverfast
Yeah I also follow the guide, lock exposure etc.
The only thing I do differently is I donāt use auto bits per pixel on the input tab. I find that for some reason it doesnāt always use infrared cleaning. So I set it to 64 bit RGBi to force it to.
I can see the dust & Scratch cleaning working in preview. I can even see the infrared scan part happening when I have hit scan. It just doesnāt seem to save into the final scanned image.
Very oddā¦ Are you on the latest version of VueScan?
I am. Did the whole uninstall reinstall job as well.
This is a historical issue for me that I still havenāt found a solution for. Since moving to Catalina, Vuescan generally has been very buggy for me in general. And itās definitely a Vuescan issue as I also have Silverfast which has been running fine.
Think you may have replied to my facebook post in the group! Hahah
Before my 8200i I used an 8100 which doesnāt have IR. But I did notice some strange stuff going on with the scans using vuescan, I would get odd ācoloursā around the sides of the images - I knew it wasnāt a scanner issue has I didnāt have the problem with Silverfast! But yes I have noticed some issues with the latest version of vuescan and the 8200i - namely the IR removal. I compared 2 images scanned right after each other. One with IR removal on heavy and the other with no IR removal. It did get rid of a couple of dust spots but not as much as I would have expected. I would open up a ticket with Hamrick but I donāt know if that would work as Iām actually using my dadās license for vuescanā¦ And I have seen in the past that he has been a bit rude as you said above.
With that saidā¦ I will try on my windows machine and see if itās any different on there (not much help as youāre on a Mac though!)
Anywayā¦ what version of Silverfast do you have? Is it AI?
Hmmā¦ it sound like you have the right settings. Sounds like an issue with Vuescan. It should be saving the results of the IR removal in the raw ouput.
Hereās from the manual:
Output | Raw output with
This specifies which operations in VueScan cause the raw scan data to be written to a file.
If set to āScanā (or āPreviewā), the raw file is written at the same time as the scan (or preview). In this case, the raw file has not had infrared cleaning or grain reduction applied.
Assuming that the preview is used primarily to prepare for the final scan, this option should normally be set to āScanā so that the highest resolution raw image can be saved.
If set to āSaveā, it is written at the same time as other files are written (i.e. after a scan completes or when the Save button (p. 47)is pressed). In this case, the raw file has had infrared cleaning and grain reduction applied.
I too have experienced rude customer support from Hamrick in the past, but not really sure what else to try?

Heās still replying to my emails for now so Iām going to keep trying to find a solution.
I have even tried emailing the guy who wrote The Vuescan Bible but had no reply.
