overexposure

Postby lestru » Sat Feb 09, 2008 6:10 pm

Hi everyone,

I have noticed that when I scan my negatives after clicking invert on photoshop many of them come out overexposed even if they are not and it takes lot of curves to correct it. Generally these are pictures with bright areas, taken on sunny days.

I always set Silverfast SE on 16 Bit HDR Grayscale to get a TIF file.

What do I do wrong?

Thank You.

Have you tried to use Negafix and select the type of negative you are scanning rather just making a straight scan and invert in PS ?

Perhaps this is causing the exposure issue ?

Try adjusting Negafix in expert mode. If they are mostly biased to the same extent, then this is pretty efficient.

Dear lestru

reading this, I get the impression the negafix curve your dealing with needs correction. As you yourself unfortunately cannot achieve this (because the curves manipulation is only available in an Ai version of SilverFast), please don't hesitate to contact support:

We will need to know what scanner and Negafix profile are in need of optimisation here. Thank you for your kind cooperation.

Best regards
