After you’ve posterized your photo, check out some of the other editing options available to you.
Make basic edits.
In Photoshop, you can quickly change the image size or aspect ratio, or crop your photo to get just the size you need for printing or sharing on social media. You can also correct small spots or stains with the Healing Brush tool.
Go from posterized to poster.
Put your posterized photo on an actual poster with templates for InDesign, Illustrator, or Photoshop.
Try different artistic effects.
Transform your photos in Photoshop with a huge selection of other smart filters. Create colored pencil or stained glass effects, or just blur the background. Watch tutorials to learn more, and have fun browsing the gallery and applying filters.
Whatever style and mood you want to achieve, you can find a way to realize it in Photoshop. Keep experimenting, and see what you can make.
