I'm looking into the world of AI for headshots and I have a question that needs to be answered. Are there any reliable and free AI tools out there for enhancing or editing on this website. I've heard of some paid alternatives, however I'm on a tight budget and would like to know if there are any hidden gems that are available in the domain for free. For the retouching of backgrounds, background adjustments or any other improvements I'd love to learn of your experience and tips. Your suggestions will save me lots of time and effort, so do submit your feedback and inform me if you have an affordable AI tool that you trust. Thank you!
