Hi, I've completed the RAW class. Can you help me understand the cause/effect for the warning revealed in PS (CC) with the View Gamut Warning please ? What do I do/not-do to ensure an edited image in ACR doesn't break the gamut warning ? Screen shots show PS (time 12.05.23) the ACR histogram (12.05.02) and the ACR image (12.04.42) sRGB 8-bit. Thank you, Andy
