Hox to make white text readable on a background

Personally, I'm firmly opposed to any kind of outline or shadow on text 😉

I think this is fine as it is, I can read this without any problems. The background already has been darkened with a lowered white point, which is just how I'd do it. If it still doesn't seem to be enough, lower it a little more. But I don't think it's necessary.

EDIT - oh, OK, I get it. You want to know how to do it. Just put a Levels adjustment layer over the background and pull the output white slider (the lower one) to the left.

Don't change the background.

Add a stroke and/or drop shadow to the text.
