To scan a slide, a flatbed scanner must illuminate the subject from above,

scanner, or if it's a one off job sub it out.

I know this probably isn't the answer that your looking for, but, if you
don't use the correct tool for the job, you will spend years regretting it.

By the way, how old and how many slides?

Thanks both. Looks like a lost cause then! Maybe a new scanner...
