Before after sliders

Hello, perhaps this topic has already been discussed so please forgive me because I’m not sure how to search for this information on the site. I would like to illustrate my color editing skills and would like to incorporate a before/after slider for my web images. Can this be done in Backlight?

Yes. Use the Theater add-on’s Compare feature

This feature is also available in the WP Theme, if you’re using that. So, Theater for album presentations, and WP Theme for blog posts.
