Make Star Trails From a Single Photo in Minutes! 

Nice trick tho

I noticed that right after I uploaded. Just a quick mask and it's done.

Unfortunately that doesn't work. The horizon and light pollution takes over the photo pretty quickly with long exposures. And you would need an hour or longer single exposure.

That would expose only the light pollution, f/11 with base ISO won't show you stars, only the brightest few.

I messed around with it that way and wasn't getting the results I wanted. I would love to see it done that way to see what I was doing wrong.

@@ChristopherBurress There is no right or wrong in photoshop as long as you end up where you want. :)

I suppose that really is the measure of success in ps. This may have been more steps but didn't take long in all reality.

@@ChristopherBurress But I would say that cmd+shift+F is one of the best tools in Photoshop since very early versions in 199X years. I almost never use it for opacity fading but instead for choosing blend mode to any earlier move, that in it self does not have it. What comes to radial blur, it is not so easy to set up exactly at point. And ofcourse it is blur, but after blur (always done to copy layer) you could easily separate just highlights, go to cmd+L and make everyting maximum bright, if edge blur has not enough opacity, you can always make copy of that layer and cmd+E them down which will stack partial opacities. Another tool that people do not get is raw tool, because of it's name they limit it's use only for raw.. I dont, I use it for every single layer, very effective on non raw multi layer images in photoshop.

Thanks! Figured it out by accident lol
