RE: PS CS6 64-bit This discussion is regarding geospatial, 4-band imagery where Adobe PS interprets the near infrared (NIR) band as an alpha channel (4th band). During the PS editing session, all 4 channels are active with only RGB visible. 4channels active RGB visible.PNG <https://forums.adobe.com/servlet/JiveServlet/showImage/2-10497807-1526857/4channels+active+RGB+visible.PNG> Edits made to the flattened (i.e., no layers, background), such as cloning operations, appear to include editing the active, but not visible, 4th band. However, there arises the issue of when using layers, edits are made, then the document is flattened, only the RGB channels reflect the edits with the 4th band unchanged. How can one edit all 4 bands using layers? I've also posted this question on Adobe's PS forum:How to edit 4-band imagery using layers? <https://forums.adobe.com/message/10497807#10497807> -- Untitled Document Mr. V.
