I'm looking for a piece of advice. I discovered such thing as HDR photo processing, and I'd like to upgrate my Photoshop a bit. So, I need a plugin for creating such images.
Of course I have already googled for some tools and the article about professional plugins for photoshop https://macphun.com/blog/professional-photoshop-plugins recommends the one called Aurora HDR. I'm a bit afraid of buying it since I just want to try, and I'm not sure my skills are so professional

Could you please suggest me any free or cheap Photoshop plugins for HDR processing?
