Have just inherited a working older rangefinder camera which I want to use a bit. I don't have a scanner and would like to know which instructions to give the high street lab (or if neeed be other) so that I can process the scanned files as RAW files.

They'd need to be scanned at high resolution (say 4000 dpi) with the scanner set not to sharpen or enhance and the output saved as a tif file. Not the sort of job the average high street shop is very likely to be able to do - they'll usually only do lowish resolution scans saved as jpegs to a CD.

"RAW" files are native to a particular camera and are not strictly a 'type' of file. It's a generic term, unlike .jpg or .tif.
My 2p - get a high street store to scan all of your negs as jpgs. Put them on your PC and have a look at them and then scan the negs of the ones you like yourself, saving as a .tif(f) or possibly your processing software's native filetype (e.g. .psd in PhotoShop).
(If you have a scanner!).

I don't know of a scanner that produces RAW files and don't really see how it would be possible bearing in mind that it is scanning full colour information. It would have to convert the scanned information to the form that a camera can't help create which seems odd.
The nearest thing to do is to scan with everything switched off and save as a TIFF. However, dust will show up and I'd suggest at least having ICE, or equivalent, activated.

You can't scan a slide into a RAW format.
RAW is the unaltered information from the camera sensor.
Scanning a slide will not allow you to alter the image in the same way you can alter a RAW file.

The OP could use a slide copier attachment on a DSLR and obtain RAW filae in that way but they would do better by going for as high a resolution as possible with as much depth (? bitrate) as possible but that won't be cheap... It would probably be more economical for them to buy a good neg/tranny scanner and do it themselves.

They could do it that way, but then they'd just be adjusting the photograph of the slide, not the actual 'data' on the slide.

Unless you find a service that specializing in slide scanning, it is going to be hard to find any typical film processing service that offers customized high-end scans.
If you want to scan the film yourself or hire a high-end scanning service, the closest you are going to get to raw is something like the 48 bit HDR function in the Silverfast software. It is pretty close to raw output from the scanner. The resulting scans are rather flat but all of the "information" is there and you can do your own tweaking as opposed to letting the scanner/software do it. It still really isn't the same as raw from a camera though. Vuescan offers its own "take" on this too.

If you scan to a Tiff, you can then save that as a Photoshop RAW file (*.RAW) in PS. I think you can then open that via bridge to ACR to edit it.
I may be wrong, it has been known!

You can actually open almost any file in bridge (RAW, tiff or jpeg) and then right click and open in camera raw or control/R. When scanning with the Epson do it in 48 bit colour at 4800 dpi, turn off sharpening and turn on digital ice if you have it and save as a Tiff and it will give you a print at somewhere between A2 and A3, so if your only printing A4 then scan at 3200.

Er, Vuescan offers a DNG RAW capture option on its scanning software. Any digital imaging device captures 'RAW' data by definition, just most don't offer the option of saving in that format. RAW just means the data as captured, without the parameters of colour balance/sharpening etc being applied.

Not according to this man.

No. Check your facts. A VueScan RAW is actually a TIFF file.
You are scanning in information that has already been (for want of a better word) written.

I stand corrected.
Strange though that my Vuescan TIFFs don't handle noise as well as the DNGs. There must be some difference. That piece is well over a year old - I wonder if changes have been made in that time?
