As a commercial photographer (ground and now aerial) and photography and Photoshop instructor, I work extensively in Photoshop, initial edits in Lightroom if doing batch processing. My
P4P drone is set to 4:3 aspect ratio, which translates directly into common sizes 4x6, 8x12, 12x18 (my often used poster size), 16x24, etc. Any special crops you might want, including vertical format, NOT directly available in the drone, and based on who is printing your photos, can be edited in most popular photo editing programs, including Photoshop Elements, Photoshop, Lightroom and online sourced software. You need a good editor, know how to use at least the basics and then make sure it matches the capability of whichever printing service you use. I like Costco... good quality for most things, good prices, and convenient from my location. One additional thought, if you are shooting images and want the very best editing quality and capability, shoot in "RAW" mode rather than .jpg. DJI offers .dng as RAW, which is Adobe's version of RAW, and that works well in my photo work from the drone. All in all, as good as the camera in the
P4P is, I am getting very sharp and well exposed images, easy to edit in any of my work. Attached is an example of the quality of the images I capture, taken as .jpg (before I switched to drone RAW), edited directly into Photoshop CC, and "shrunk" to fit Facebook uploads. I hope this helps. In the meantime, welcome to Paradise CA.
