Hello, I am brand new to lightroom. Is version 3.3 the same as 7.0 that I keep reading about? I'm so confused and I would love to load some presets that I have into lightroom but I just cannot figure it out. When I watch videos for PC it shows some weird menus that are not on my lightroom for my desktop.
No. Lightroom 7 never really existed, but that is what is now called Lightroom Classic and is at version 9.3. Lightroom 3.3 is a new application that stores the originals and edits in the cloud. It's a pity that Adobe decided to call that 'Lightroom' too, because it leads to constant confusion, even years after its introduction.
Without knowing what your intentions are, it's difficult to make a recommendation. Lightroom Classic follows the Lightroom tradition that has been around for more than a decade now. It is the most robust and versatile. It stores images locally on your computer, but provides a feature to share collections if you want to do so. The "new" Lightroom is designed to store your images in the cloud, enabling you to access those images from your computer, smart phone, tablet, and other mobile devices, being able to edit them on all those devices and see those changes on any other device. It doesn't have all the features that Lightroom Classic has. That doesn't seem to bother many users, it frustrates others. The interface for the two programs is radically different. You need to understand what it is you want from Lightroom and make a decision which you want to use because it is very difficult to run a "mixed" workflow.
