Frozen aspect
Hi,

we have a project to get a frozen car by adding some texturing on a photo.
an example of the freeze is : http://imgur.com/0NXPB1Y
-> it represents frozen aspect on a red steel painted surface.
Another good ex of the freezing aspect we have in mind is:

My roomate told me to use few times render difference clouds on top of each other to bring up more details but I dont get anything close to that frozen aspect..
Any idea how I could achieve something like that?

thanks Smile

RE: Frozen aspect
One quick way would be to
- have the frozen ice texture on the top layer.
- Change the layer mode on the layers window to something that will blend well.
- Click your car layer
- Make a selection around the car
- Select > Invert
(to select the background)
*Optional: "Select > Feather" for a softer edge around the car*
- Click back on your ice texture layer
- Push delete
Adjust the layer opacity to control how much the texture shows
or
Change the layer mode again to see if there is a better blending mode.

*If you want half of the car frozen, try a layer mask.

EDIT/update:
*click for bigger image
(Steps to achieve on left side, final layer comp on right)

In the final composition I added
- HSV noise
- Layer mask radial blur (to make it look like its freezing over)
-Neon outline(tube)
"Filters > Alpha to logo > Neon..." (match glow as best as you can)

RE: Frozen aspect
Hi,
looks not bad and good creative ideas.
the problem is that I need to generate that frozen aspect from the scratch, from Gimp,
because it should be in a layer on top with some transparency between the freezing spots, which I will fit on top of the carrosserie (which has its own color, logos, name,etc)
so the top layer should contain only the frozen stains with no paint.
To generate the frozen aspect, I thought at the beginning to use difference clouds which gave a not so bad result but still far from the
texture to see on these:

then I tried to create few clouds on top of each other to give it more variations but didnt manage to get a good result,
Do you think it is possible to do that?

thanks, I posted there and somebody gave me the idea to google Frost instead of Frozen and I found new ways:
I post the result of my search here also, it may help somebody sometime :

see the tests I did on the red color down..:

I used the brushes from:

"Obsidian Dawn Frost Brushes" which gave good effects, specially the nrs :
SS Frost025 + SS Frost022 or SS Frost007->009

Other brushes worked also nice like:
texture01
texture hose1
britsles
acrylic04

I found also a tuto, it is for photoshop but I think it can be used also in Gimp, didnt manage it though:

u can by google these words: tutorialwiz frost snow
there is a picture of a bush in there:

To convert it to Gimp:

The channel mixer in Gimp, I found in: color/components/channel mixer
and used "Lighten only"

It works like that I think: everything that is white becomes very white and produce snow effect

If somebody manage it, I would be curious to have some feedback how ;-)

I post some of the results with these Frost brushes:

RE: Frozen aspect
Hey, sorry for the absence, I got busy with work.

Great that you found a very nice result. For the white parts.

A way to make the white frozen parts:
- make a white background layer
- make a new "transparent layer"
- bucket fill your "transparent" layer with red
- Then click the eraser tool (can work like a brush too!)
Pick any of those brushes that you found for texture
Erase the layer by clicking or using the "[]Apply0 jitter" option
Then merge the transparent layer to the white layer,
change layer mode to "lighten" or "screen" or a mode that blends well.

I used the acrylic 03 brush (see pic #1 below)
Yet another option instead of "apply jitter" turn on "Fade Tapering" in the Dynamics options (pic #1)
Then to enhance the ice/frozen standing out, you can change the color of whatever object is under the ice layer (see pic 2)

RE: Frozen aspect
Hi,
I found the option Fade Tapering very helpfull in that case, it introduces more randomness and life in the end result, same thing for the jitter option!
thanks for your post Smile
