I have been using Lightroom in my laptop for many years. It is my starting point for all my photo retouching and cataloging. Over the last year, I have been preparing myself to use LR Mobile: I now have all my photos in one catalog, created collections for my portfolio and my travel photos.
At first I only a as going to use LR Mobile to show my photos on my mobile devices. But when Adobe announced they where adding shooting in RAW/DNG to the LR Mobile app I knew I had to try it. And it was well worth it!
You can shoot RAW/DNG from right inside the Lightroom Mobile. Your RAW photos get stored in your catalogue and are automatically synced to your desktop. I used to have to connect my iPhone to my laptop and import the photos into my Lightroom catalogue before I could retouch them. And as they were JPEG, my options were limited.
Now, when I get home and my iPhone is connected to WiFi, it syncs with my desktop and photos automatically apear in my catalogue. Shooting RAW on the iPhone means you can use all the familiar tools and sliders in LR. You are able to correct your photo like you would with a RAW photo from your dSLR.
Another advantage of LR Mobile is the ability to edit right on the iPhone itself. Most of the tools and adjustment options you know from LR (that is if you are a LR user of course) on the desktop are available on LR Mobile as well. So instead of having to wait for you to get home, you can edit on your iPhone or iPad, export to JPEG and share on social media right away. And the cool part is, your retouching is synced with your desktop catalogue too!
If you are already a Lightroom user on your desktop, I highly recommend LR Mobile.
I have a couple of sample photos I shot with my iPhone 7 and LR Mobile over the last few weeks. They have been retouched with LR right on my iPhone. I was really impressed with the quality of the photos. Even the concert photo turned out pretty good.
