if you take a screenshot on iphone, the screenshot should linger at the bottom left of your screen for a little bit. if you click on it, that's where you can edit the screenshot like cropping it or drawing on it or whatever.
anyway, if you take a screenshot and click on it while its in the top left, towards the top right above the screenshot itself it should say like "Screen" on the left, which is the default, and "Full Page' on the right of that.
click "Full Page' and you get a full page screenshot!! You can take a single giant screenshot of raws (website for raws is: tkor.band --- make sure when you're looking for a website on that site that you use the korean hangul title) with good quality this way. it'll usually save as a pdf, but you can easily turn the pdf into an image file there's a bunch of free, easily accessible websites for thatヾ(☆▽☆)
