I'M NEW TO DIGITAL PHOTOGRAPHY. I HAVE PHOTOSHOP CS2 AND
COREL 12 AND AN EPSON 4990 SCANER WITH AN EPSON 2200 PRINTER.
I WANTED SOMETHING TO TAKE ALL MY FILM PRINTS AND MAKE SOME
NICE IMAGES. IT HASN'T WORKED. MY PRINTS LOOK NOTHING LIKE
WHAT I SEE ON THE MONITOR. I'VE PROFILED THE MONITOR, SCANER,
AND PRINTER USING MONACO EZCOLOR WITH OPTIX. SOMETHINGS WRONG! IT'S ME. WHAT I WOULD LIKE TO KNOW IS THIS:
UNDER OPTIONS/ CMS/PROFILES FOR ICM/ SCANNER REFLECTIVE
THERE ARE THESE CHOICES:
EPSON PERFECTION 4990
EPSON PERFECTION 4990TPU
SF_R (EPSON PERFECTION4990)
SF_T (EPSON PERFECTION4990)
WHAT'S THE DIFFERENCE AND WHICH SHOULD I TO USE? :roll:
THANK YOU FOR ANY HELP YOU CAN GIVE. THANKS!

Dear Confelicity (great nick, BTW 8) )

EPSON PERFECTION 4990
Generic profile provided by Epson for reflective scanning with this scanner.

EPSON PERFECTION 4990TPU
Generic profile provided by Epson for scanning with the transparency unit.

SF_R (EPSON PERFECTION4990)
Indivdual profile which had been generated by you with the IT8 calibration option for reflective scanning mode.

SF_T (EPSON PERFECTION4990)
Indivdual profile which had been generated by you with the IT8 calibration option for transparency scanning mode.

I suppose your trouble stems from the fact that you probably had SilverFast configured to use some image adjustments while generating the scan for the Monaco software.

When you use a third party's software to calibrate your scanner, you need to ensure that SilverFast scans the image without any auto-corrections.

In order to do so, please open the SilverFast options dialogue:
- on the "General" tab, check the "for HDR output" box.
- make sure the gamma value is set in accordance with your monitor and Photoshop settings.

When you do your scan for the third party profiling software, select "48 bit HDR color" scan mode type on the "Frame" panel of the main dialogue.
