I’m OLD school. I like to hold books. I downloaded this e-book to give it a try. While on vacation and sitting in our motorhome i started to read this, then I read something new and wasn’t aware off, so I thought, I’ll open up my Lightroom and check it out. Wow that was easy and fun. Read it, try it, learn it. What a great format. and it’s always on my computer along with Lightroom. This has definitely changed my way to learn. I am ready for the next book!
