Re: Fabulous Filters - GMIC>contours, Lighting Effects, Path Blend +++

oldmangrumpy · **Posted:** Thu Apr 30, 2015 4:01 pm **(#1)**

I have been playing around with the Lighting Effects filter and, I know my saying it is boring, but I am astounded (yes again!) at what it can produce. Just looking at some holiday photos and applied the filter randomly to some of them. Just using the bump facility against a desaturated version of itself can really make the photo detail stand out and then there a the extra effects ...

yes it really does!

OMG : did you make some preset?
will be interesting if you share them

oldmangrumpy · **Posted:** Thu Apr 30, 2015 7:32 pm **(#3)**

Marcello - sorry, but I am only just learning about presets and have just realised that they can be saved; I will try out a few more settings and save them if they are worthwhile.

this is my test with the following settings
type POINT
x=2.40 y=-1.50 z=1
mat.properties 0.50,0.50,0.50,27
enable bump mapping linear max height 0.05

original

Wow!!! I like that a lot OMG (you always trying out) with so good outcomes. That is great in my opinion and it gives photo a great look in detail. :clap

Marcello, yours is great. You got the point of OMG. :clap

This looks amazing - I will need step by steps on this one, and write slowly, so that I can follow it slowly...thanks

OMG, every filter is a mine for you, and you are able to extract gold from wherever! Congrats!
in this case the pupil is Marcello...hehehe
I agree with Marcello, OMG you need to save your setting and share them when you find nuggets...

Awesome, OMG. You come up with the nicest stuff.

Here's a link to a picture on APOD of MESSENGER's Last Day on Mercury. I think it would make a very cool texture for one of your great lighting examples.

I took the liberty of trying to straighten the NASA image.

Well I am humbled by your pleasant comments -
@Issabella - thank you again you are so kind always.
@PaulOClassic - sorry but I am just experimenting at present and I have no 'step by step' instructions ; well not as yet anyway.
@Dinasset - again as always I thank you.
@Oregonian - thank you for your pleasant comments and also the heads up on potential E-map sources; only just started trying that parameter out - see below.
@MarFisk - I really appreciate your kind words, glad you like the pics.

Here are some more attempts to use/understand this Lighting Effects filter ...

A rebuilt wooden Russian Orthodox Church on an island in the Baltic Waterway. Top left is original, then I moved through different settings and finally used an e-map too..

oldmangrumpy · **Posted:** Sat May 02, 2015 4:17 pm **(#13)**

@Oregonian - here is the same image using your referred lunar blue image as an e-map with various settings for both light and bumping. The use of the sinosoidal curve for bumping in the top right version gave it an interesting background.

And then extending the finishing touches with blending and other e-maps to simulate night time shots ...

Love this filter!

It was a clear starry full moon night in London and I was just walking down this street when there was a bright flash and suddenly five hundred years of that London street appeared before me; so I took a quick photo ...

... well was it a dream or had I drunk too much of that fine Marist Brothers wine ...

I just really enjoy using a combination of GMIC>contours and Lighting Effects.

Issabella · **Posted:** Sat Jun 13, 2015 2:37 am **(#15)**

hehehehe, Great OMG!!!! that is fantastic!

oldmangrumpy · **Posted:** Sat Jun 13, 2015 2:44 am **(#16)**

Well thank you Issabella - I am actually having a quiet glass of that Marist Brothers Pinot Gris right now.

OMG

If it was not a dream and you were not drunk and it happens again in Regent Street I'll take a photo & post it.

dinasset · **Posted:** Sat Jun 13, 2015 4:00 am **(#18)**

a new shining London...but Pinot Gris was a little bit too much!

oldmangrumpy · **Posted:** Sat Jun 13, 2015 6:29 am **(#19)**

@happydays - thank you and there was I thinking I was in Oxford Street; London just seems a faint memory now. Its 50 years since I was up there every weekend playing football. :roll:

@Dinasset - you can never have too much Pinot Gris.

And now just one more - from fractal to GIMP to GMIC>contours to lighting effects ...

... you can never have too much GIMP either.

oldmangrumpy · **Posted:** Mon Jun 15, 2015 1:09 am **(#20)**

Another JWildfirefractal put through a similar GIMP/GMIC contours/Lighting effects process -

... it keeps looking at me!
