I didn't know that. I have no issue with others replacing a sky but I made a decision to never do it myself. That may change one day. I use the tools to enhance files. Balance exposure between subject and background, which he did in the darkroom with his wands. I did that too. Selective sharpening and shadow/highlight tune ups. I'll go nuts with masking to bring out as much as I can of the existing sky for my B&W. If there is brach in front of a bird I won't remove it. I'll have to do better next time in the field.
On a professional/commercial level I'd replace as many skies as I needed to get the job done. I think this new tech invaluable for that.
About 6 years ago we drove to Phoenix. On the way home spent some time in Santa Fe. We really liked old town. We took day trip to Hernandez. It was a too bad there was no marker and bit of write up about that capture. I guess not enough Ansel fans come there.
