Picture 4: Here you can see the brightness adjustment box (g) (also mentioned in pic 2). I brightened my picture a bit, as I know the texture I wanted to add makes it darker. You can also go back and do this after you add the texture.
Picture 5: First I clicked on the texture box (h), then the filter I wanted to use, "Grunge 3" (i) and last I adjusted the intensity (j). I prefer just a hint of texture, so low intensity for me.
Picture 6: Click on eye (k) to see the finished picture, then on "Done" (l).
Picture 8: That brings you to quite a few options of saving. To save to camera roll click first box (o). As you can see you can also add it straight into Instagram and other apps directly from the app (n), which is a pretty cool function if you ask me.
Picture 9: If you do click on "Instagram & others" as in pic 8 (n), it takes you to 7 different app options to send it on to. Click on (p) to post on Instagram.
Voila!! That was it for now. Hope you enjoyed this little tutorial. Please leave a comment if you did and I also would appreciate any feedback you might have on either picture, tutorial or app:) Have a nice weekend!
