I agree with Hill James: using the histogram is functional when you have feedback on what is going to be clipped. This could be achieved by 1. indicator color on the going to be clipped part of the image (seems complex to me to realize) or by 2. a measurement tool indicating rgb levels in 16 bit and in 8 bit numbers on mouse position. This can be used for the numeric input of clipping point of B and W. (should be easier to implement)
A histogram is a big aid, but should be paired with some visual feed back on what pixels in teh image are BP and WP. jan albrecht ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, December 15, 2001 1:54 PM Subject: Re: filmscanners: VueScan Histogram was VueScan 7.3.2 > In a message dated 12/14/2001 12:46:00 PM EST, [EMAIL PROTECTED] writes: > > > Last I heard indicated Ed didn't wants to add a histogram to VS so we may > not > > get a chance to ask him to change it again and again... > > I think the best way to do this is for me to just add a histogram and > then evolve it using people's suggestions. > > It's quite possible that a simple histogram of the preview (within > the crop window) and the scan will be good enough.
