I'll note outright that I'm new to Photoshop and that this may be a bigger question than I realize, but I appreciate any guidance.
I've taken a scan of a water-damaged dust jacket for a book which I would ultimately like to recreate. I chopped it up, straightened it, and used the Spot Fix tool to fill in losses and create a 'complete' image. Here's my progress:
At this point, I'd like to either 'extrapolate' that lovely blue color from the flaps to the rest of the image that can be printed onto appropriate white paper, and/or remove the background entirely so that the text can be printed onto equitable blue paper.
I've taken a look at some answers here about the Magic Wand tool, but this text is so fine that I'm having trouble cleaning it up. Is there a better way to go about 'extracting' this text to its own layer?
