It isn't easy! Go to http://www.adobe.com/products/photoshop-lightroom.html
When you get there scroll all to way to the bottom of the page and in the lower right you'll see the Lightroom 6 buy button.
You still might want to think about the Photographer's CC plan. It's a real deal at $9.99 a month.
Gene: Thank you so much....not sure if it's 'operator error' or because I have a Mac or that I use Chrome as a browser (both of which, I know, can change screen appearance on certain sites), but I don't have the buy now for LR-6 when I scroll down. However, my husband was able to find the LR-6 alone on Amazon. Yay! I agree that the CC Plan is a great deal. And, honestly, if I ever decided to sell photos, I would be so tempted. I know that most of the younger people in my life do everything on their phones and iPads, too, which appear to be additional benefits of the CC products, but I'm just a dinosaur who takes a ridiculous number of average photos and, while it would be fun (or totally frustrating, I'm not sure!) to learn a whole new set of post-production skills, I think I would mostly be overwhelmed by it. I just need an easy, intuitive program to adjust lighting and to occasionally adjust vibrancy or contrast. I know I don't even use LR to it's full potential. Thank you again for taking the time to answer my question! :-)
The version at Amazon is the full version of LR6, not the upgrade version which you qualify for, and is less expensive than the full version. If you don't see LR6 at that link using Chrome, you might want to consider switching to Firefox or Internet Explorer for 10 minutes to make the purchase, it (probably) won't kill you
LMAO, dj_paige! Oh, fine! I went to Safari and it actually worked! And, thank you for the reminder. I didn't ask my husband if he'd found the full version vs. the upgrade. Can you see why I don't need the PS and other elements in the CC?! I'd probably implode. PS: why doesn't Chrome play nicely with (apparently) anyone else?!
