Check out the quality of Sam Rohn’s shots. Quite nice for a 360 camera!
Dual Fisheye Plug-in is free
DNG Transfer to mobile phone is free
Note that you only need this for a mobile workflow. If you edit the pictures on your desktop, you can transfer the pictures with a USB cable and edit in Lightroom and Photoshop.
Z1 Stitcher is about $15
Note that if you have a desktop workflow, you can use the free Lightroom Plug-in. You only need the Z1 Stitcher for a mobile workflow.
If you want to work with 16bit floating point super high dynamic range RAW images, you need the Z1 Stitcher. The adobe lightroom plug-in will stitch 12bit DNG (which is the default coming from the Z1)
DualFisheye Plug-in Remote is $18
You don’t need this to use the plug-in. However, if you like the free plug-in, you may like the plug-in remote to help your workflow. And, the cost is reasonable.
