I am a new user of Silverfast(SF) and just brought a Epson V700.

I have testing a lot the past few days and notice a big improviment by scanning the negatives with HDRi 64 bit and black and white(BW) HDRi 32 bit. Got much more shadow detail and much less noise. Haven't used yet on slide film but i am sure I might have some improviment.

I use the SF SE version and when I scan this way the TIF files still as a negative file so I have to invert the color in Photoshop(PS), adjust the exposure and colors. But I have got much better results.

Am I doing this in the right way or there is an easier way to scan this way without doing all the adjustiments in PS? What improviments beside multi-exposure could I have upgrading to SF SE Plus?

Of course, you have much more details and information to work with using HDR raw files.
Actually those files also contain a 16 bit infrared channel with information that could be used to correct scratch and dust. That channel can not be used by photoshop. It can only be seen by SilverFast HDR or HDR Studio which is one of the main advantages you have using HDR or HDR Studio.

The other advantage using HDR Studio is the conversion of Negatives into positives. Using NegaFix in HDR Studio, piece of cake! The orange mask is automatically eliminated, this has to be performed manually in photoshop.

If you are to work in HDR mode, the main advantage with SE Plus Multi-Exposure would be Multi-Exposure.

By the way your examples are not attached to the message, one of them could be opened by right-clicking and calling it in a different tab.

Cheers

Awesome

With SE Plus am I able to process 64bits files?
I have a V700 and what I see in preview mode comes out darker when scanned in 64bit. I am kind of having trouble scanning Slides since it is difficult to get the right exposure, highlights and shadows come out way to noisy thats why I think I might need multi-exposure at 64bit. I am getting better results with this slides scanning at 48bit through Epson software using color restoreration and backlight correction but stay some noise on it.


which versions come with HDR studio?

thanks, Joaquim.

Actually using SilverFast SE Plus you can create 64 bit HDRi files. To process those files you need a second application called SilverFast HDR or SilverFast HDR Studio

They come out darkly because pictures have a linear gamma (or a gamma value of 1.0) To apply a gamma curve with a value different to linear you need to do it using an editing application (for example SilverFast HDR or HDR Studio).
