Try a search in the patch library for color burn?

In the patch library pulldown, these are under Image > Composite Operation. Also there's a macro called Composite which is simply a bunch gathered together in one patch for convenience.

Try running this file in your QC installation. The top left and bottom left images are those being combined and the right hand image is the resulting blend. The type of blend achieved is shown in the text above the right hand image.

Re: can i use color blends and how

What you are doing wrong with quartz-test? You are not using the blend mode patches as best suits their means of operation and you can achieve the result you get by ditching them entirely and then feeding the images you have embedded in the composition directly into the Billboards.

im working on a experimental project...making multi layers interactive by sound....im trying to recreate the layers from photoshop art...i have only some layers that will move..but i need to make the layers blend to achieve...

Re: second attempt

For the third layer you could ditch the Composite Overlay and simply adjust the Alpha of the Billboard's colour , then it will blend over. In the attached picture the 3rd layer Billboard is set at 50 percent Alpha [White].

Re: can i use color blends and how

Actually, if you look at quartz test 2, the 1st Billboard set to Replace can seem pretty redundant. Unless of course, you also set Billboard 2's Alpha is also diminished from a full 100 percent and Billboard 3's Alpha colour is set to a slightly lower level in the attached picture. You can also set Billboard 3 to a higher level to that of Billboard 2, adjust Billboard 1's Alpha colour too.

Re: can i use color blends and how

so the limit for blending is between only 2?

Re: can i use color blends and how

A] no there is no such limit on the number of Billboards placed over one another. The compositional construct you provided had its first Billboard rendered redundant in one set of settings and made useful in another set [sentence beginning 'Unless'...]

B] the construct screen grabbed by jersmi is a correct way of utilising the stock blend patches to appropriate the sort of result you were seemingly seeking. The Composite Color Burn would need to be set to Source Over. The Composite Overlay could also be set to Source Over.

Mind you, I think that without a screen grab of how the Photoshop file looked that you were seeking to replicate in QC, one could only hazard a guess as to what would be the best mix to use.

Re: can i use color blends and how

thats gettn better...i can do multi blends...but now i noticed that even though i use same blend in photoshop as in quartz the image is different....i broke down the quartz the exta info is sittn on top...and attatched a shot from photoshop....the difference is in the face....

my other question...i have sound input...how can i apply it to the x cordinate of the face in this sequence....i can apply it to seperate billboard but how do i within the sequence

Re: can i use color blends and how

Regards your 'other' question, try using an Image Transform between the image and then input to the Color Blend patch. Feed the required mathematically computed audio data into the input appropriate to your desired effect on the Image transform patch. Like that Photoshop composition BTW. Very smooth, nice combination of colours.

Re: can i use color blends and how

You might look at the dissolve patch, too.

Blends are RGB math operations between images, pixel to pixel. For ex., Addition (which photoshop either calls something else or does not have, i don't remember) creates a new image derived from R1+R2, G1+G2, B1+B2. Addition makes things brighter, which makes sense when you think about the operation, whereas multiply makes things darker, etc. Theoretically the operations should be the same across programs, but the other ways layers are handled matter, too. (Thus cybero's comments on Billboards and layering in QC).

Personally, I don't care at all about the differences between photoshop and quartz composer because they get used in drastically different ways in my workflow. If I really had to match something, then I could certainly work to come as close as possible, but that has not once ever come up for me. So here I have some unsolicited advice: if you are animating, don't get sidetracked with the details of matching stills because once you start animating, the transitions will change/override any other concern. Just make the new QC animation look good with the content you have established.

Re: can i use color blends and how

What exactly is this thing supposed to look like... you're posting this pic w/ the face, but it's not in your source file (the face).

This can be done using just composite blends and one Billboard, and will tend to be "better" - the composite blending is not intense, and is probably better than running three Renders (not that this is a real intense process either way).

All of the photoshop blends can be done in QC. I don't remember if everyone of them is represented, but I'm 100% sure that if not, the blend can be achieved using a shader or CI. The differences you may run into are with gamma/color correction.

Re: can i use color blends and how

actually the source file for the face is embedded in one of the other source compositions on this thread.
