Film Scanning - finding the dynamic range

I dabbled a bit in film a few months ago and now that things are a bit quieter I can devote some more time to it.

I've something to ask though. Film has a lot more dynamic range than digital...but...I'm used to RAW.

So when I scan I have TIFF files, which aren't RAW files.

Is the additional dynamic range present in the TIFF file or do I need to do the tweaking before I scan?

Thanks!

If you scan the film to preserve all tonalities between black and white, all will be there.

Your scanner might have a hard time capturing all detail in the densest part of the negative / slide though…

Canon's raw file is in essence a modified tiff. If you scan and output as a 16 bit tiff, you have all the dynamic range of a raw file.

… as long as you're not clipping whites or blacks in raw conversion

With one difference. RAWs are in linear space, tifs generally are not (unless exported from a converter like DPP that lets you skip the gamma correction step). WB, for instance, is best done to linear data.

How do you tweak a negative?

As in setting certain parameters before I scan the negative.

I used the Epson V700 a few months back, put it away and am digging it out again. The software that's with it has a huge amount of settings.

Oh, right, I understand now. What the software does is done after the physical scan. Aside from WB and the application of a film profile (if the Epson software allows you to choose one) it's pretty much a matter of convenience if you do the editing in the Epson s/w or in another editor.

Ok cool, I'm just concerned that I'll be operating in such a way that I'll lose the benefits of shooting film in the first instance. It was never something I learnt with so is a very big black hole of info to me.
