Post OT: Need Paint Shop Pro/Photoshop help....

Here's my problem. To facilitate better printing and viewing, I'm trying to touch up some service manual scans I made. The scans are .jpgs, approx 1700x2100. My goal is to take out the yellow of the paper and enhance the black text. I have very limited graphics editing experience (I use JASC's Paint Shop Pro 5), and I have tried using the color replacer, changing to grayscale, and various edge and sharpen filters (and all of these in various combinations) to accomplish my goal. Some have come close, but nothing has resulted in quite sharp enough text. I figured I'd be better off asking for help than pulling my hair out any more. If anyone can give me some pointers on this, it would be greatly appreciated.

BTW, the images in question can be found here.

I haven't used Paintshop Pro, but it might have similar features to Photoshop for dealing w/ this.

In Photoshop, First, I'd Image-Adjust-Desaturate which would make the image grayscale turning the yellow to gray.

Second, I'd use Image-Adjust-Auto Levels. This takes the lightest gray tone and cranks it up to white and takes the darkest gray tone and drops it to true black.

Then, I'd try Filter-Sharpen-Unsharp Mask to clean up.

Finally, I'd make the image grayscale, 8bit. This will reduce the file size for quicker downloading.

Hope this helps.

Craig

Yeah, you really need to desaturate them (take out all color) and then turn up the contrast a bit. You might try to sharpen them a little, but I'm not sure how it'll turn out.

To get the image size down, export as a GIF, maybe 8 color or so, you might be able to get away with less without losing much quality, maybe 4 colors.

Those are beautiful scans, BTW. No crease in the center or anything.

Have you tried setting your scanner to black&white only? That helps a lot on mine when I am working with older photographs to get the yellow out, should work the same for your project.
