Film Negatives

I dunno if this is in the right forum. Sorry if it isn't.

I'm trying to make a VB program that develops negatives. I've scanned the negatives and stored them as bitmaps. I've tried inverting the colors but that doesn't work. Is it possible to apply some algorithm to the colors, or is there no substitution for the chemicals used in developing?

Thanks

You need a special scanner. Normal scanners bounce the light off, but for nagitives the light needs to pass though the image.

Yes you need a "dias" scanner to scan negatives..

To invert colors in VB:

Add a picturebox and set its property autoredraw to true and scalemode to 3.

Add the picture you want to invert.

Create a button.

in Command1_Click add

VB Code:

Dim X As Long
Dim Y As Long
 
Picture1.DrawMode = 6
 
For X = 0 To Picture1.ScaleWidth
    For Y = 0 To Picture1.ScaleHeight
        Picture1.PSet (X, Y), Picture1.Point(X, Y)
    Next Y
Next X
 
Picture1.DrawMode = 13

cyborg, read the question a little more carefully. If you know much about how printing nagitives and a regular scanner works, you would see why the inverting colors wouldn't work.
