RE: filmscanners: Bypassing the scanner software filters and getting the raw data?
Yes, one of the reasons behind me asking the question. The Minolta software is fine for simple adjustments but only enables you to preview on small lo-res scans. I'd much rather work on the full scan in something like Photopaint (What?! someone who doesn't use Photoshop and actually likes Photopaint?! I must be mad!). I'd be interested in knowing what the reasons are for prefering adjustment in the scanning software as opposed to the main paint program. If the actual hardware output is fixed, then surely it doesn't matter which you adjust in - it just comes down to which package enables you to get the best results. Mark I tend to agree with you--if you're going to correct in the image program, what's the point of correcting in the driver program? Or vice-versa? OTOH, not all programs are equal.

Re: filmscanners: Bypassing the scanner software filters and getting the raw data?
I think the driver software allows adjustment to exposure, color channel by color channel, and thus provides better correction, especially for negatives. I don't think the actual hardware output is fixed, the final scan is performed after you make adjustments in the driver. Other than color negative reversal, I believe most of the concern about doing corrections in the driver software vs subsequent adjustment in an image editor is addressed by editing 16 bit per channel files.

Re: filmscanners: Bypassing the scanner software filters and getting the raw data?
Hi, Mark-- Don't know about Minolta's native driver (and my Acer's Raw scans aren't very sophisticated), but Vuescan does a very good job of outputing Raw scans. I tend to agree with you--if you're going to correct in the image program, what's the point of correcting in the driver program? Or vice-versa? OTOH, not all programs are equal. Best regards--LRA From: Mark Edmonds [EMAIL PROTECTED] Date: Mon, 6 Aug 2001 19:01:12 +0100 Hi all, Is this possible and is my logic correct? I am reasoning that the output from the actual scanner hardware is always going to be in the same range of digital values irrespective of what adjustments are made in the scanner software (apart from resolution of course). Therefore, is it possible to get the actual raw data out of the scanner and bypass any processing? What I am aiming to do is to have all my scans coming out at exactly the same setting (ie: no processing) so that they all have a common base and then I can adjust with whatever software I am using over the following years. My scanner is a Minolta Scan Speed and I am running NT4 with the standard Minolta scanning software. Thanks for any comments!

RE: filmscanners: Bypassing the scanner software filters and getting the raw data?
What you are getting is basically a raw scan. If you are going to do this, making corrections and adjustments later in an image editing program, you should probably make sure that you are getting high bit 16 bit linear scans, which will involve selecting that option in the Minolta software driver. Some have argued that it is better to make curve and levels corrections at the scan level rather than post scan; but for what you want, I think that you will be ok. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Mark Edmonds Sent: Monday, August 06, 2001 1:01 PM To: [EMAIL PROTECTED] Subject: filmscanners: Bypassing the scanner software filters and getting the raw data?
