We can work directly with your Adobe Lightroom Classic (2017) Catalog or Adobe Lightroom CC/6 (2015) Catalog & provided Smart Previews. This is generally the easiest way to transfer your images to us for editing, and us to deliver back to you.
If you don't currently use Adobe Lightroom, or need to upgrade to Lightroom Classic CC, we recommend signing up for the Adobe Creative Cloud subscription plan. They offer a Photography plan for $9.99/mo. Which includes Lightroom & Photoshop, and always update date and compatible with newest gear.
You’ll find more info here: https://www.adobe.com/creativecloud/photography.html
If you don't use Adobe Lightroom CC/6, we can also work with your RAW or DNG files. We recommend shooting and sending us RAW or DNG over JPG format. You can learn more about Raw vs JPG here: RAW vs JPG - The Ultimate Visual Guide from slrlounge.com
If you have JPG images, we can accept them, however our processing may be limited by the data provided within the JPG images.
