How image annotation works
Image annotation involves reviewing the layout and design of images, pictures, illustrations, etc, and leaving all the comments right on the image so that it can be amended and enhanced. Each image markup is an incredibly important part of the image creation process because it's a step closer to finalizing it and making sure that the image conveys the intended message.
The best review process to annotate an image online is as follows:
- Create an image
- Image is submitted for feedback
- Real time feedback of the design elements is provided using an online annotation tool
- Clients or team members annotate images online by pinning feedback right on the individual elements that need changing
- Feedback is centralized in one location for easy management
- Further annotations are made if required
If you're still using email, Word, MS Paint, or even Slack to provide feedback, stop right now! It's inefficient, messy, and it often leads to confusion and misinterpretation. Start annotating using the right online annotation tool and you'll never look back.
- Increased accuracy
- Faster review process and fewer revisions
- Centralized feedback reduces back-and-forth
- Easy collaboration for remote teams
- Helps meet deadlines without compromising quality
