Claro is a server solution. Photoshop Inspector is a client application of Claro that can be used on workstations with Adobe Photoshop. It allows to view (and retouch) original and processed images (processed on the Claro server) side-by-side in Photoshop.
Photoshop Inspector is used to confirm the result of images enhanced on the Claro server. The retoucher can confirm the processed image, sending it back to the Claro server in order for the workflow to be completed. Before confirming it, he can use Photoshop tools to further tweak the processed image. He can also decide to choose the original image, retouch that image manually in Photoshop, and then choose to send the (retouched version of) the original back to the Claro server to complete the workflow.
