Go big or go home?  How about a light painting using the Sun.  That's pretty big.

Been meaning to do something like this for a while.  300 images of a sun rise taken at 20sec intervals. Images were then combined in The Foundry's NUKE to form the light trail caused by the arc of the Sun's ascension.

NUKE, chomped through and combined all images to make an average, and a max filtered version (where only the highest value between two adjacent images is preserved).  Then by combining those two images we get this.

The lens was a vintage Canon FD 28mm, with a 1970s era Iscorama 54 anamorphic adaptor.  The combined flaws from this old gear really became apparent, and help create the vintage mood.

Drawing hearts with street lights.

I had the shutter open for about 6 seconds whilst in the car in pooring rain.  Then I moved the camera in the shape of an upside down heart.  This image is the result of two such photos added together.

NukeStudio: Clip/Track additive blending

For anyone wanting to do additive track blending in NukeStudio v10+, here's a step by step.

1.  Starting with two over layed tracks.  By default the top one takes precedence and hides the lower one.



2. Convert the top track to a blend track via the right mouse button menus.  The track header should turn blue.



3. Right mouse over the overlay clip add a BlinkScript soft effect.



4.  Expand the code section, press Clear to remove the default code.  Then copy and paste my code and hit Recompile:

	kernel jrGainRGBA : ImageComputationKernel<ePixelWise>
	{
	Image<eRead, eAccessPoint, eEdgeClamped> src;
	Image<eWrite> dst;
	param:
	float alphaGain;
	float rgbGain;
	float4 multRGB;
	void define(){
	defineParam(alphaGain, "alpha gain", 1.0f);
	defineParam(rgbGain, "RGB gain", 1.0f);
	defineParam(multRGB, "multiply", float4(1.0f,1.0f,1.0f,1.0f));
	}
	void process()
	{
	dst() = src()*multRGB;
	dst() = float4(dst(0)*rgbGain, dst(1)*rgbGain, dst(2)*rgbGain, dst(3)*alphaGain);
	}
	};

5.  Switch to the Kernal Parameters tab.  Here you will be able to multiply the RGB and A of the overlayed clip, as well as separately controlling an overall Alpha and RGB gain.  Setting Alpha gain to zero is the quickest way make the clip additive.  (Note that these parameters multiply against each other.)



6. You can add other soft-effects, like transforms, other grades etc and things should behave as expected.




Please add a comment if you give this a go.  I would be interested to know if this is useful.

Cheers,

Jeff

Homage to social isolation and moral degradation.   Or just a bleak shot of dt Vancouver on a week night.

Shot this subject before.  However, I thought the material and the light playing off it had a pretty interesting satin quality this time around.

So often my path is crossed by a silhouette of some sketchy looking character.  Perhaps my reaction should be to find another path rather than try to take a photo.  Oh well.

So starting in the gutter, just before an ill-fated illegal poker game spewed, violently, into the alley way.  Not really, but totally could have happened.
