I know there are people out there that have no interest in Lightroom mobile or Photoshop, so here’s how to get Lightroom 6. It is a bit hard to find. Adobe are keen to have people go to the cloud. I think it’s great value, but I totally understand why people want to have a version that feels like their own.
Go here: https://www.adobe.com/products/catalog/software._sl_id-contentfilter_sl_catalog_sl_software_sl_mostpopular.html. Click Buy, then change “I want to buy” from Full to Upgrade. In the next part ‘I own’, choose the version of Lightroom you’re upgrading from. This will give the upgrade price. Add to Cart and then checkout to buy.
