when i work on an image , i create lots of alpha channels , is there a script/action to delete all with 1 click?
i run ps cs6 64bit , windows7 64 bit
i found a short script but it's amazing slow
What are they used for? I have been using PS for around 3 years primarly for web design and I have never used channels outside of loading a selection. I searched for more info; I mostly got tutorials that use alpha channels, but no real explanation as to what they primarly do.

Everytime I try to copy and paste under LOAD Selection, i get the 3D picture stuck with the black background or totally white with no picture when paste onto the 2D picture. I want to paste the 3D picture(minus the black background) to blend into 2D picture.

how can i apply the alpha channel to the original to get all the green stains out?
When importing some flat TIFF files from Photoshop CS5 into After Effects CS6, AE asks what kind of alpha channel these images have — straight or premultiplied.
What type of alpha channel does Photoshop use for non-layered TIFFs?
Using PS CS4, I noticed that obviously every layer in the image has its own Red, Green and Blue channel. But when I add an additional channel (Alpha channel), the contents there are not stored per layer, but "globally" i.e. one alpha channel for the entire image. Is that correct, or am I doing something wrong? Note that when I add a mask instead of an alpha channel, it does work as expected (each layer can have its own mask, just like they each have their own R, G, B channels).

Can you copy both the RGB color and the Alphachannels?

I'm using the Lens Blur Tool and when I finish running the tool, I am not seeing the result it should have applied. I know, "DUH!" but I can't figure it out.

I want to export an image file (Targa, 32 bit, with Alpha Channels) into photoshop, then extract the alpha channel(that being the black background in this case) so that i'm left with the actual image of the 3d model over transparency, with which I can use to layer on top of things created in photoshop. Ok, that said, i'll explain it one more way, in hopes to make it clearer. I'm doing weather graphics for a news program, and have rendered out a cloud in a 3d modelling program(3d studio max). I want to import this image of the cloud into photoshop, and layer it over graphics I created in photoshop, minus the background created in the exporting from the 3d program.

why duplicate a channel?
I cannot find much on the web about it, how to use an alpha channel. However, none of them address this issue.
I use photoshop cs3 extended.
I am using png and tga image formats
When using an alpha channel, you can set the alpha to absolutely transparent. However, when you do and save the image it removes the other channel information on the rgb channels. This is problematic because I have to use a 1 transparency value to retain my rgb channels. This causes issues as I need the full alpha but also the texture information.
This is for texture work on a game and the engine uses the alpha channel for a team color overlay on top of the rgb image. So I need all 4 channels rgb for texture, and the alpha is a team color overlay.
I am still a hold out on using Quark Xpress (v6.5 for Mac OSX 10.3.9). I would like to use product photography in my layouts that include drop shadows that would have a transparency effect once placed in Quark. I suspect that this needs to be done with Alpha Channels in Photoshop, but for the life of me cannot figure this out.

I'm creating a text layer, and then applying a simple drop shadow to it. but when i create an alpha channel it ignores the dropshadow and only creates the alpha for the basic text.
i know its possible using the "magic wand" but i have to apply this to over 100 different *.psd files so want to be able to easily automate it..
at present to create an alpha channel i use CTRL + the relevant text Layer, then go to CHANNELS + SAVE SELECTION AS CHANEL
I'm in a process of making assets for Unity3D engine and I'm making transparent png's with alpha channels premultiplied with black. My questions:
To this day I've been using superPNG plugin to add alpha channel because it was really hard to find option to do it in Save As... menu. Today I've found Export -> Render Video where I can choose PNG and premultiplication. Am I doing something wrong or is it the proper Photoshop way to export png via video function? It seems really hidden!I can do the same for TIFF, PICT(i suppose no pict for me because its pure mac extension?), and tga format with one black layer and ticking Alpha Channels box, but its somehow greyed out for PNG? Why is that?
I have PSE9 and need to create an image without the background (mk background Alpha Channel) and save as Targa. I can edit the pic, save at 32 at 200k but PSE9 does not allow to save/create Alpha Channel. How do I make the (background an) alpha channel and save as Targa?
View 1 Replies View RelatedSome .BMP files.
I need to save some images with transparency that are in .BMP format, but said images seem to have what's called an alpha channel, which covers all of the image's background and not the transparency that I need. I've tried to use the "Convert color to alpha" option, but it appears that that only works in the image that I want and not in the alpha channel itself (yeah, I didn´t know what alpha channel was until then).
I leave an example of one of the various .BMP files that I want converted to .PNG with transparency.
Is there anything that can be done using an alpha channel, that can'tbe done using masks and layers, or vice versa? Context of question: I've worked extensively with masks and layers.I've never worked with alpha channels.For example:
Using an alpha channel:
1. Open two single layer images, A and B, neither one of which has analpha channel.
2. Drag the image B over to A and close B.3. Now image A has two layers, A and B. Put layer A on top, selectlayer A, set the blend mode to Normal, and add an alpha channel.4. Erase part of layer A, where-ever you want layer B to show through.At this point, layer A has an alpha channel with white where you wantlayer A to show, and black where you want layer B to show, but it doesnot have a mask.
OR
Using a layer mask:
1. Open two single layer images, A and B, neither one of which has analpha channel.
2. Drag image B over to A and close B.3. Now image A has two layers, A and B. Put layer A on top, selectlayer A, and set the blend mode to Normal (don't add an alphachannel).
4. Create a solid white mask for layer A. Paint black on the maskwhere you want layer B to show through.At this point, layer A has a mask with white where you want layer A toshow, and black where you want layer B to show., but it does not havean alpha channel.
In both cases, using a mask or using an alpha channel, the net resultis the same.So again, is there anything that can be done using an alpha channel,that can't be done using masks and layers, or vice versa?
Basically, I am trying to use an alpha layer/channel to export a picture that is transparent except for a grass clump that is colored green over the alpha layer. So the picture looks like a solid green rectangle, but is actually a green blade of grass.
Problem is, I cannot get the alpha layer to work. I can't follow the tutorial as it is in photoshop, and random videos on-line haven't worked.

I haven't tested every single combination yet in the publish menus. To save me trying them all, is there any option that works to publish all the shots in a sequence together with alpha channel?
I have a sequence of CFXa clips with matte output connected in CFX, I duplicate the sequence and commit cfx... every clip has a matte container. So far, so good. Now I want to output the whole sequence as individual shots with alpha.
Tried the EDL option, changing file type to OpenEXR... no alpha. Tried EDL, changing output type to movie and then selecting ProRes 4444. Alpha was solid black.
Is it possible to get publish to create individual movie files for each shot at all? Everytime I try this it writes one continuous quicktime file even though I select a shot number token. Writing individual shots seems only to work with image sequences, is that the case?
when I try to save a tagra file with a alpha channel in photoshop 7 the box for the alpha channel is greyed out, with an warning sign next to it, and the line below stating "file must be saved as a copy with this selection" When I examine the saved file the alpha channel is not there!
Has anybody got any idea why?

View 5 Replies View RelatedI am experimenting with Smoke 2013 pre-trial and I am having issues with importing images and video with alpha channels.
1. If I have a layered Photoshop file or png with an alpha channel (a still frame lower third), I see that I can import it as a multi layered clip, but what is the best way to have it in the sequence to show up properly?
2. If I have a QuickTime in animation format or Pro Res4444 format with an embedded alpha, how can I import that file to show and cut it on a top layer to animate above my video?
I got single clip in desktop and it got an alpha embedded. If i drag that clip into the cfx , the clip will be interpreted correctly where alpha will be recognized. The problem in action is when i drag into action schematic, the alpha is ignored Smoke should know if there's alpha embedded then by default it should use it. ANother problem is when in media list , i add new media then click the clip twice (to grab F and M from the same clip), the result : i got blank alpha. Again it should load the alpha while there's alpha embedded . I think , this should become the dafault behaviour to deal with alpha. Although loading this clip in cfx schematic will solve the problem, i think the action still need to be fixed.
Also it should be cool feature if i can drag the clip from library and drop it in media list , and it will replace the media of the selected item in media list.
I can't find the trash can under the pallete to move the action I would like to delete in to.
