For this particular tutorial, you'll have to go get the PS Express app. You'll also have to make an account so that you can use all of the filters and such.

A F T E R

1. Open selected photo in PS Express.
2.

Open the corrections tab, which is the blue in the photo.
3. Play with clarity, sharpen, and reduce noise. For me, I typically just put all three up at max or just below it.
3.5 I'm actually really in love with this, a big thank you to martymxfly for putting this in her (amazing) tutorial book. Which you should definitely check out.
4. Open in Phonto, add your title and stuff, and wam!
