Tried a couple old sunset photos I took myself, to try out Pop and other techniques needing reds/blues. They are not recent. Sorry.
Grunge textures attempted for Part 6:
B&W Texture: https://www.flickr.com/photos/kyabean/47970772656/in/photostream/
Blue texture: https://www.flickr.com/photos/shaireproductions/5195942946/in/photostream/
Concrete (this one I went with): Photo by PPD on Pixnio
And another: https://www.publicdomainpictures.net/pictures/290000/velka/gray-concrete-texture-1547356215P7K.jpg
Gave my own pics a try for HDR. Learned a lot! I'll stay more still next time, for example...
Re Pano: Is there a way to "stretch" the edges of some layers, like the top left corner where the sun is? I wanted to just manipulate it over to the corner of my cropped area, along with the blue sky to the right as well...
