Question Re Scanning Slides

Mon Oct 29, 2001 1:58 am

After shooting color print film for years, I decided I'd give color slides a try. I shot three rolls (Fuji Sensia 100), had them process by Fuji in Phoenix, AZ and have to admit, the slides looked fantastic. When I tried to scan them using my Minolta Scan Dual scanner/Vuescan software and the same color settings I had used for the Fuji Reala negatives (gamma 2.2, brightness 1.0), I got very dark scans. I brightened them up by increasing the brightness setting to 2.0 with the following results:

For comparison, the following shot was taken the same day using Fuji Reala. The results are quite different!

The blue sky seems be overpowering, to the extent where the aluminum skin of the C-82 appears blue. BTW...I used Photoshop 6 software and normally adjust the scans using the clone tool, the unsharp mask and occassionally, the contrast/brightness settings.

What am I missing here?? I see so many great looking pics using Sensia film and the Vuescan/Scan Dual combination. Any help would be greatly appreciated.

Ralph,

I now use gamma 2.8 in VueScan 7.1.17 - this newish version doesn't have a Brightness setting (with older versions of VueScan I used to use a lower gamma but have the brightness setting increased above the default). It might be worth you checking which "color balance" and "color space" settings you are using - I find "White balance" for the former and "sRGB" for the latter to be most effective.

If you haven't, it might also be worth changing the "media type" setting on the device tab to "slide film" and make sure that the "slide vendor" setting on the color tab is set to "generic".

Other than that, I can't explain why your skies go so blue.

Hi Andy,
Had all the settings per your suggestion. Decided I'd try the latest version of Vuescan so I downloaded v 7.1.25. Although the scans were a little dark, the color of the sky was a "normal" blue and it didn't overwhelm the entire pic. Must have been something with the version I was using. Do you know if there is any way to lighten up the scan from Vuescan? I can do it with Photoshop but seems to me that it would be better to scan at the proper brightness rather than lightening it up later.
Regards,
Ralph

I sometimes try to pull upp the gamma when I have a dark photo, at times I've had it up to 2.8 or 3.0, but I usually leave it on 2.2

On another list I read that Ed had recently (ver. 7.1.20) made a mod to Vuescan to handle blue skies better (on request from an Av. photographer I believe!).

Apart from playing with the Gamma, I sometimes find using a experimenting with the colour space helps. While I normally use sRGB, CIE rgb gives pleasing results with very saturated/contrasty slides.

Cheers,

Thanks guys,
Looks like the new software with a gamma of 3.0 does the trick for me. Scans are comparable in quality to the Reala negative scans.
