.........."Aligned layers now ready for averaging (if between them still remains shifts or rotations, we need to try another aligning method). In Photoshop, averaging can be performed by one of 2 methods: Method 1, simpler and effective (available in Photoshop CS2 and newer) - using smart objects. We just select all source layers and apply menu command Layer > Smart Objects > Convert to Smart Object. Then, in menu Layer > Smart Objects > Stack Mode we choose "Mean" and wait until averaging was done". ........................My problem is that stack mode is dimmed, I have tried 2 different descriptions how to average images and got the same result -stack mode is dimmed. Why? is this function not included/activated in CS6?
Not sure why you're having problems, it works fine for me in CS6 and CC
Stack mode is only available in CS6 Extended, not CS6. Which do you have?
That explains why I can´t stack my photos, I hav just CS6, nor extended
