Hi ,
I read an interesting article that you shared, here: theemptywallnews.blogspot.com/2011/10/1028-digital-photography-school-post.html - thanks a lot!
I found your piece while I was looking for Photoshop resources, and it reminded me of an article I read last week about free filters and plugins: https://www.websiteplanet.com/blog/best-photoshop-plugins-filters/
This is a fantastic piece with very useful (and free) plugins and filters all gathered into one place. The article even teaches you how to install these plugins and filters, which is great.
I recommend you share this article with your readers as an additional resource, I'm sure they would find it helpful!
Best regards,
Isabel
