I opened a RAW image in Camera raw, did some cropping and colour adjustments and then opened it in Photoshop to work on it further. When i returned to Bridge i realised that the original raw image had little icons on it with crop and adjustment symbol. the original had been changed and now i dont have the untouched raw file anymore :( help!! what am i doing wrong? i thought edits in camera raw will not affect the original raw file. do i need to make some setting changes?
