One thing I notice with that image is that there's a "hotspot" most likely caused by a flash, you see this with any piece of paper that you photograph under a flash. Before you do other corrections, fixing the hotspot so that the center and the edges are a more even brightness helps a lot.

I do this by creating a graduated radial mask that approximates the falloff in brightness, I then use that as a selection, and adjust the brightness of the image. That is, I'll brighten the edges and/or darken the center of the image as selected by the mask.

You can do a mask like this in Photoshop in one or two steps, probably similar in Paintshop. Here's the before and after of a selection and radial brighten, your original on the left, the mask in the middle, modified on the right. Its a subtle effect, but the thing is, getting even brightness impacts everything else, notably contrast and vibrance, so you do this correction first. The tricky part is estimating the mask, which you have to do by eye, a bit of trial and error.
