Masking for Sky Replacement Lightroom/Photoshop for iPad

[JarrettT]

Hi guys,

I'm trying to switch my workflow over to my iPad Pro and lightroom etc from my old MacBook Pro.

A big bit of my work is replacing the sky in my images and it involves me masking out some intricate things such as power lines, antennas, chimneys and trees etc.

Any tips on this? I used to use landscape pro for this which did a very good job, but I cant find a way on photoshop to do this effectively.  The selection tool seems to be very touchy with no refine option etc.

I have plenty of sky textures, just need an effective way to mask out the sky.

I used to reduce the file size using a jpegmini plugin and then drags them into wetransfer to get them ready to go, but I'm struggling there too.

Any tips from some of you pros out there or apps that would help would be very much appreciated.

Thanks
