Darken individual letters

[miguellint]

Hello...

I have a list of names similar to the one in the linked image below. Eventually I'd like to ocr the list.

I'm trying to darken the light letters only and have experimented with a few of the Brightness/Contrast scripts from Fred's ImageMagick Scripts.

My attempts leave all of the letters quite blocky. (The example is a bit extreme but you see what I'm getting at)

Any suggestions as to how to proceed.

Hello Fred...

Thanks for the examples. The negate/lat/negate example is exactly what I'm looking for. Thanks.

And can I also say that your multicrop script is pure wizardry. Jaw dropping wizardry at that

All the best
