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?
My old version of photoshop 6, allows you to save alpha channels!
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.

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).

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'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?

Some .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?
I need to know how to save an individual color channel. I am able to split the channels, but they are in gray and not color. How would I save them in color? My PS is CS5.

I don't think we're the only one that needs to have straight alpha?
I have a series of files in which I improperly modified the selection set prior to saving the selection, and now around the intended viewable area there is a hazy artifact that seems to correspond to where I manually edited the selection using Quick Mask (prior to saving).
In other words, within the area of the alpha channel that should be invisible, there is actually a visible, unwanted grey-ish artifact, and I think it's related to how I was using the brush to edit the selection in Quick Mask before saving.
Now I am unable to edit the alpha channel, although Adobe's own website says that in order to edit an alpha channel, all I need to do is select the alpha channel (which I am doing) and then paint at 100% black or white with a brush to either include or exclude parts of selection set.
When I choose the brush and start painting at 100% black or white, nothing happens and I can't figure out what is happening.
The exact steps that I'm taking are below:
1) click on alpha channel (visible and ready for editing), all other channels only visible not active.
2) selecting the brush at either 100% black or white
3) attempting to paint to alter the alpha channel (I've tried painting on the actual alpha channel in Channels, and I've tried painting on the alpha channel as it appears in Layers, and neither works for me).
CLARIFICATION:
I actually am able to "edit" the alpha channel HOWEVER I cannot remove the hazy artifact. I can use 100% black or white to remove the pink/light red areas on either the actual alpha channel (in the Channels area) or as it appears in Layers, but I cannot remove the areas that are grey-ish (well I can paint them white but I can't paint them black, i.e. fully pink).
A teacher showed me a quick fix process that basically involves activating the alpha channel, inverting the selection, and then deleting everything outside of the alpha channel, and then resaving the file. That worked at one point, but now that quick fix is not working either (I am just ending up with a completely visible, white space around the intended visible area, rather than an invsible area).
EDIT (07:22 3.20.13) Also, if you look at what Photoshop is registering as the actual alpha channle, it doesn't match with what I'm seeing above, that is the black and white alpha channel appears to be as expected, and there is not the weird distortion that I'm seeing above in the pink/grey image.
Saving selections and alpha channel masks?
View 2 Replies View RelatedI thought that I could just use Quick Mask to manually paint with 100% black or 100% white to adjust the boundaries of the selection and then save that final selection as my alpha channel.
However, I'm discovering that when I do this, I end up getting a weird grey-ish artificat (which incidentally, I can't figure out how to remove it). How I should be properly modifying the selection prior to actually saving it.
One project I use Photoshop CS4 for is painting aircraft used with Microsoft Flight Simulator X (FSX). Each aircraft is downloaded as a "Paint Kit".I paint and add layers onto the kit until the aircraft resembles the design I chose. The paint kit includes a background, base parts usually in white, and an assortment of layers adding physical wear, shading, lines and rivets you see on actual aircraft.
Additionally, the kit includes an RGB Alpha Channel and Specular Maps. In this application, the Alpha channel provides the reflectivity or gloss on the aircraft paint. The Specular maps provide a sheen much like the subtle reflections you see from a metal flake paint job when the sun hits it directly.
Once all painting and manipulation is complete, the kit is "cut" into specific sizes. Once the kit is cut, each section is saved as a DDS file using NVidia tools. The resulting DDS files are placed into folders within the main FSX program folder. The FSX program "assembles" the sections and processes the different layers and channels resulting in aircraft that are incredibly detailed and realistic.
My problem is I don't know how to properly integrate and preserve the Alpha channel during the "Flatten Image" and when saving the file as a dds file. As you can see in the "Layers" section in the picture, the Alpha channel is already made. I just don't know what to do with it to preserve it and ensure the reflectivity it provides is visible in the final product.
what I need to know isn't what the alpha does, but how to properly integrate it into the final product. I've searched for this info for the last several days, but I've had no luck in finding specific information on how to do that. URL....
I 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?
