Hi, How do I place a glass surface over a plain colour background ? Something like what Aero did. When I tried with a plain background, the blur simply dissolves into it and show no effect of a glossy surface.

Please see bg + blur try which I did. It does not have any glass effect at all. Do we need to introduce turbulence into the blurred layer ? I don't know how to do it in a uniform way. I tried to do it using brush, which gave very poor results.

I'm not quite sure what you are looking for and I don't know Aero either, but I have been known to play around with glass effects

The image below uses a filter to produce various thicknesses of flat glass - the rectangle represents a thin glass layer and the circle a thicker glass layer on top. Let me know if this is what you are aiming for and I will post the filter.

[meetdilip]

Yes, yes.

I would like to imitate the thin layer as we see in the rectangle above. Thanks.

By Aero, I meant Aero in Windows 7. The transparency they used.

Adding a border method is very effective. I would like to add some blur to it as well. Not a 100 % see-through glass. I tried adding blur to the white layer. But it does not make any effect on the background image. But it works great with a plain colour background.

Any ideas on how to do some glossy glass than a perfectly transparent glass will be awesome. Thanks.

Meetdilip -OK; a copy of the script is attached below; it is an old one but it does work under 2.10 and it appears under Filters>Kward1979uk>glass.

Here is one of my threads dealing with glossy glass viewtopic.php?f=11&t=13158

Here is a tutorial of mine dealing with clear but contoured glass viewtopic.php?f=23&t=13491&hilit=brumby

Hopefully that will keep you busy for a while.

[meetdilip]

Thanks. I tried to figure out from those threads. Tried the first 5 pages on both threads, now I think I don't know much about GIMP.

Meetdilip - if you have any questions or problems ... simple, just ask

[meetdilip]

Thanks. Please see the wallpaper below. I am trying to replicate it

Thank you for the script. It works in Gimp 2.8 but not in 2.10.18.

[oldmangrumpy]

jappaloe1963 - I am running 2.10.18 and the script works OK for me.

meetdilip - I was intrigued by your post above (#8) so I had a very quick play at your target wallpaper; no glass, just FG/BG gradient, brushes and blurs.

[meetdilip]

You are awesome. I missed this post since this was in page 2.

It will be great if you can give some description of how you did it.

[meetdilip]

Your tips were great. I didn't think of a brush stroke with a large brush size in white colour. Once I painted a few soft areas, I applied blur to the white brush stroke layer. Then added a bit opacity to it. The plain gradient wallpaper was in the layer just below it. I used " Luminance " mode on the brush stroke layer which now has blur and opacity.

Luminance works much better than Overlay in this case. HSV value was also looking good.

meetdilip - that's good; I'm no expert in this area, but you can experiment more and use various brush sizes in blurred black or white to get more depth/contouring in your image or use slight variations of the main colours too. As for impact of different blend modes, looks like you are already there. Keep it up

[meetdilip]

Thanks.

I was trying to learn this since some time.
