Smart objects Photoshop dummy
Have an issue that I can't seem to fix - call me a Photoshop dummy.
I'm doing BW conversions in NIK Silver Efex Pro 2.
I opened my image in Photoshop, Created a 2nd background layer called it BW conversion and changed this layer to a smart object. I have then opened the NIK software done a BW conversion and closed the NIK software. I now want to clean up small bits that have only become evident after BW conversion but seem unable to use the clone tool or the spot healing brush tool on either the smart object layer or the original background layer. I have tried to create a new background layer above the smart object layer but no changes come through in the BW image.
I' sure this is simple!
Thanks Tom
