Possible in Photoshop?

[dbates]

I don't have Photoshop in front of me so I'm not completely sure, but try making the two circles 100% filled (not partially transparent), placing them in a layer set, and adjusting the opacity of the layer set.

thx for your answer buddy - that will work like you said BUT
imagine that the first red circle layer is a shadow ( from a footage )
And then the shadow got a opacitiy (not in Photoshop, but in real)
There lies the problem. I hope you get what i mean.

well if one is less than 100% it will always blend somehow...thats natural...

are you saying you have something transparent and want to make it solid?

then you need to make a selection and fill in the transparent pixels.

no guys, i meant it different.


okay next try:

Imagine you have a footage material with an object casting shadow onto the floor. Now i create in 3dsmax a matte object / material and buid up another 3D Object which will cast a shadow across the footage shadow.

When i take the too layers in Photoshop - then i got the problem mentioned before. I know there are certainly ways in any post to do that, but i wanted to know if it is possible right in Photoshop and without any layermask action.

When i put the cgi shadow (Matte Shadow) across the real footage shadow they will multiply eachother and thats the problem.

I thought it would be somehow possible to "union" the layers in order to get "one" seamless and equal saturated shadow. (The simple example with the two red circles..)

I hope this is a better explanation...

Thanks for your answers so far...

Ah. . . I see what you mean. Sorry naik, I don't think it's possible. . . not without layer masking.

I don't think there's any practical way to do it in Photoshop.

[naik]

hmm thats a pity... nevertheless thanks for the answers guys.

My friend told me that in Digital Fusion the layer mode which will blend these two layers into one is called "maximum" but as you all know there is no layer mode in Photoshop.

I thought perhaps there is a way for that purpose.

The maximum blend mode is called "lighten" and the minimum is called "darken." To blend shadows you can use darken and the result will not be darker than either shadow. The most correct way to do it is to composite each shadow on the same background, then "darken" the two images together.

In cs2 you can edit multiple layers at once, you can try using shapes and add the shapes together using the "3d term" boolean operations. I'm not sure if it might work can't try it out myself as i'm still using cs.

You can also try playing around with the blending options of the layer and its knockout. Blend if comes close but it leaves a edge.

Try this:

Double-click the upper layer in your stack which you are trying to blend to bring up the layer style window. Down the bottom, play with the sliders. These can be really handy to get certain layers to blend without using masks etc...

I recreated your red circle blending scenario and got the two layers to appear 'unioned' by moving the black triangle on the bottom slider almost all the way to the right.

You may find this handy when you are comping your 3d stuff. This won't work in all situations but play around with the sliders and the 'blend if' pulldown menu.

Also be aware that you can actually 'split' the triangle by holding option when dragging which gives you better/smoother results depending on your situation. Once again, play with these to find out how they work.
