Photoshop :: Channels/Alpha Channels?
Jun 29, 2006What 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.

Sep 20, 2002blending 3D pictures(w/ black blackground) into another 2D picture with alpha channels in that 3D picture. 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.

Photoshop :: TIFF Alpha Channels
Jul 16, 2013When 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?
Photoshop :: Alpha Channels Are Global, Not
May 21, 2009Using 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).

Photoshop :: PS-CS: Alpha Channels Question
Feb 28, 2004I don't use Alpha Channels that much; well, actually, never, so I don't know how to do this: When applying an effect to an alpha channel, how do I "apply" it to the finished image? 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.

Mar 14, 2003transparency and alpha channels. I'll explain what I want to do, and hopefully someone can tell me how. I'm creating an image in a 3d modeling program. 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.

Photoshop :: Image Alpha Channels
Apr 29, 2008I 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.
Photoshop :: Alpha Channels & Quark
May 19, 2006I 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.

Aug 25, 2005im trying something very basic on Photoshop 7.
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

Photoshop :: Creating Pre-multiplied Alpha Channels With PNG And Other Formats
Aug 7, 2013I'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?

Nov 2, 2013Some .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.
GIMP :: Alpha Channels Vs Masks
Sep 27, 2012Is 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?
GIMP :: Alpha Channels And Exporting Transparency
Nov 25, 2012Basically, 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.
(Here is the tutorial: [URL]...... from 08:40 - 09:30)
(I have also attached my practice file as a TGA)
AutoDesk Smoke :: Can Publish Export Clips With Alpha Channels
Nov 24, 2013I 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?

Jun 9, 2012I've been working with the tutorial link below to get rid of some stains, While I have no problem working directly on the channels, I'm lost as to what it means to drag the channels onto layers. I can't seem to find a reference as to how to do this. Most likely I don't have to correct term when I'm searching.
"I normally drag the channels out onto layers to make the repairs. This gives much more control, especially if graduated masks are required. On this occasion and for the sake of simplicity I've made the repairs directly on the channels."

Photoshop :: Alpha Layers
Aug 14, 2009I am currently making a skin for a boat, for a game called virtual skipper. Anyway I am doing this in PS Elements 7.0. I need to add alpha layers/channels to make the sails slightly transparent, or not transparent. I can't seem to find anything that tells you how to do this in Elements. So I assume it is not possible, or no one has done it before. So if anyone can help me with this, please do. I have made an adjustment layer and added white 80% transparent, over the sail layers. But when I save this as .DDS will the white adjustment layer dissapear like an alpha layer and leave semi-transparent sails or will it come out as it looks?
View 1 Replies View RelatedGIMP :: Layers / Channels / Paths Will Not Display
May 14, 2012I cannot bring up Layers, Channels, or Paths. Running Gimp 2.6.10 on a Windows 7 machine. Selecting Windows...Dockable Dialogs...Layers or Channels or Paths does not bring up a new dialog window. Also there is nothing in Windows...Recently Closed Docs
This occurs regardless of image file opened. Not sure how long this has been the situation as I have not been using gimp on the computer where this problem is occurring for a couple months. Am not an advanced user though have used it occasionally for years. All other Selecting Windows...Dockable Dialogs... actions bring up window boxes normally. Tab does toggle display for the Toolbox etc. Just Layers, Channels, or Paths have an issue and I suspect it may have occurred because they were sharing the same window box. I did reset Preferences.
I am able to readily create layers on top of a base image but without the dialog box, only have access to the last one created. Also can merge down the last new layer or flatten the image. My suspicion is gimp may be displaying the dialog box at XY coordinates beyond my monitor screen displayable coordinates. There is a configuration file that saves the last used settings that I can simply delete?
