Default General/Other - Controlling transparency, PSE or Affinity

2d rather than 3d, but what the heck.

I have Photoshop elements, and Affinity Photo.
I've produced an image I like (In Amberlight 2) which I want to set in space, attached.

So, I want to put stars behind the glowing thingy, so that the black areas become transparent, and the brighter areas less transparent, showing a star background layer I will add separately.

I don't just want to cut away the black areas, but want a gradual effect, so that (for example) dark areas have some stars showing.

Any recommendations on how to do this please?
Nick

You want a 2D composite ?

1 Put your star img in 1 layer
2 Put your Glowing img over your star layer (2 layer )
3 use Screen or Luminosity as composite and see what you like most

* Screen gives a lil blur in the border of the Glow img
* Luminosity gives more sharp effect in the border of the Glow img.

Ah, thanks for that.

I didn't like the results I got with the two you suggested, but decided to explore and the 'lighten' mode looks pretty much exactly as I hoped.

See attached example...

Nick

Thank You!

Oh yeah ! I always try all the modes and see what will work better , I suggested that 2 cause if they not work nice probably it will fail in the others modes.

Nice effect you got !

Also you can use a layer painted in black in some areas do fade some stars in the background , use it in the middle of the 2 you have and play with opacity , or a circular gradiend positioned behind the glow thing it will gave the impression like the stars are fading back of the glow thing , there are lots of possibilities

That looks great Nick! That would make a really cool alien ship in a movie.

I was thinking of it as more on an "Anomaly" to use the generic trek technobabble!
