innerimager Posted January 14, 2008 Share #1 Posted January 14, 2008 Advertisement (gone after registration) This is driving me nuts. I know I must be missing something simple. I have Raw scans, that are Tiffs. When I try to rescan them I select scan from file, bring them up, hit scan.....and I get a negative again. I can't get it to scan to a positive! What am I missing? thanks....Peter Link to post Share on other sites More sharing options...

R2-D2 Posted January 14, 2008 Share #2 Posted January 14, 2008 Choose "Media" accordingly, e.g. "Color negative"... Link to post Share on other sites More sharing options...
innerimager Posted January 14, 2008 Author Share #3 Posted January 14, 2008 Thank you R2-D2!! Using chromogenic film like XP2, do I set it at color negative rather than B&W negative as appears to be the case? best...Peter Link to post Share on other sites More sharing options...
srabu Posted January 14, 2008 Share #4 Posted January 14, 2008 Hi Peter, I use XP2 a lot together with Vuescan and a Nikon 5000. No experience with RAW Files, though - I save them as 16 bit TIFF to work with them in Photoshop. "Media" is set to "Color negative". I recommend using "Lock exposure" and "Lock film base color" as described here: Advanced Workflow Suggestions Also, in the "crop" tab I set "Buffer (%)" to 20. Under "Color", try setting "Black point (%)" to 0.001 and White point to 0.05. Hope you like your scans & Best regards, Stefan. Link to post Share on other sites More sharing options...
R2-D2 Posted January 14, 2008 Share #5 Posted January 14, 2008 [...]Also, in the "crop" tab I set "Buffer (%)" to 20. Under "Color", try setting "Black point (%)" to 0.001 and White point to 0.05. One should set these values depending on the actual picture. Link to post Share on other sites More sharing options...
R2-D2 Posted January 14, 2008 Share #6 Posted January 14, 2008 Thank you R2-D2!! You're welcome! Using chromogenic film like XP2, do I set it at color negative rather than B&W negative as appears to be the case? Quote from the "VueScan User's Guide": [...]Transmissive media When scanning film, this option indicates whether you're using positive film (i.e. slides), color negative, or black/white negative film. This option causes the default film type to be changed, but also sets up the scanner for scanning orange-colored media (i.e. color negatives) by exposing the green and blue channels more than the red channel. [...] (source) So "Color negative" seems to be the appropriate choice. Link to post Share on other sites More sharing options...
srabu Posted January 14, 2008 Share #7 Posted January 14, 2008 Advertisement (gone after registration) Hi R2D2, I disagree. When batch scanning, one should set these values as I posted and then use the curve tool in photoshop afterwards. Oh - talking about "crop" -20% "buffer" only works if you set it on maximum. Just my 0.02$, and I might be very wrong... One should set these values depending on the actual picture. Link to post Share on other sites More sharing options...
stunsworth Posted January 15, 2008 Share #8 Posted January 15, 2008 I use very similar settings to Stefan, except that I scan as b&w negative and save at 16 bit greyscale tiffs. The scans will look flat, but can then be 'corrected' in Photoshop. Link to post Share on other sites More sharing options...
R2-D2 Posted January 23, 2008 Share #9 Posted January 23, 2008 I disagree. When batch scanning, The OP didn't mention "batch scanning"... But you're right: When scanning batches one must set these values for the whole batch (or for a subset of equally exposed frames in the batch, see [1]) in order to work effectively. one should set these values as I posted Where did you get these values from? You might find the following article on highlight clipping interesting: ColorNeg for mono - user notes part 3 | photostream [1] [...]If you're using the same lighting for all the frames on the roll (or a subset of the frames), you can lock the color balance by scanning the brightest frame in the series and then setting the Input > Lock image colors option. This will lock the black and white points for the scene, and will produce consistent colors for all the frames in the series.
