View Images

Connect the THETA V to your computer with a USB cable. You can view the new images you just took with a new image viewer. The THETA acts like a normal camera or mobile phone.

The THETA is called, RICOH THETA V. The images are in Fixed storage > DCIM.


You can view the images by double-clicking on them. Here’s what a sample looks like in Photos.


You can also check the properties for image details.


You can view the images in Vysor using the file manager.
