This issue has plagued me for a while now, and I've had the hardest time resolving it, but how do I really "resize" the png that is my watermark? The one that I have is, quite frankly, HUGE. Especially on portrait style images. Below is an example image. Is there a way to just make the watermark smaller?
I wouldn't change the size, but rather the color - more white, less grey, and maybe fiddle with the opacity until it's just right. You would need to do this in Photoshop where you created the watermark. Same as if you want to resize it.
