Editing and remixing
28. Photos has some powerful tools for tweaking and editing images. While viewing any image, select the pencil icon on the screen to see a range of one-touch refinishing tools as well as more detailed controls for fine-tuning and cropping. (For fine-tuning, after you select the middle icon -- the one that looks like a series of sliders -- be sure to click or tap the down-facing arrows next to "Light" and "Color" in order to see all the available options.)
29. Who says a gray day has to be dreary? While editing an image with sky in the background, go to the fine-tuning tab and then tap or click the down-facing arrow next to "Color." The slider labeled "Deep blue" will let you make a pale sky appear more blue without affecting the rest of the photo.
30. When you tap the option to save an image after editing, take note that your newly modified version will replace the original. If you want to save it as a copy instead, avoid the large "Save" command and instead tap the menu icon in the top-right of the screen to find the "Save copy" option.
31. In addition to regular edits, Photos lets you make super-simple movies, animations and collages from any set of images and/or videos. Just select the items you want, select the "+" option at the top of the screen and then choose what kind of creation you want to try.
32. Don't forget to peek at Photos' Assistant tab from time to time. The service leaves all sorts of interesting treats for you there -- everything from automatically generated animations, collages and highlight videos to "this day in history"-style flashbacks from your collection. It'll also create instant albums from related images and offer to fix photos that are flipped the wrong way.
