Photography

I used two fluorescent (meaning wide) lights, one on each side, at 45 degrees to the picture.

I did that to "scan" stuff using an ipad on a little stand above the pictures.

Complex suggestion is withheld for now. It involves a "Circular polarizer" but you might find one of those old "anti glare" screens that were often used with computer monitors. They did the same thing.

Understand about not wanting to take it apart. Some photos use sharp little pins, rather than long-ish "staples" to hold everything together. And then you have to put them back. Maybe a craft store can make suggestions or help.
