| | Digital Juice - February 2005 - Understanding Alpha Channels What Every Video Editor Needs to Know |
| | Alpha channels are digital bits of information that allow you to use variable transparency to composite multiple layers of video and animation, which is a fundamental part of build eye-catching images. | | | The method for keying out an alpha is specific to your editing system, but you’ll always want to do a true alpha key and not a chromakey or lumakey. | | | In fact, you can export an alpha channel to a separate file, which is basically just a gray-scale image mask. |

| | Mediamacros Inc. - Anatomy of an Alpha Channel |
| | Alpha Channels automatically created with Photoshop's transparency effects are ubiquitous in Photoshop files. | | | Every single layer that is not completely filled with an opaque image has an alpha channel that describes which areas of the layer are opaque and which are transparent. | | | Another way to directly create and edit an alpha channel in Photoshop is in a single layer document. |

| | Alpha Channels premultiplied, straight and uncorrelated |
| | To use such an alpha channel, one must emulate the behavior of a film optical printer — one must run the black core matte as a holdback for the background, and then add the foreground as a burn-in, or a "DX" (a double exposure). | | | Invert (~) the alpha channel and multiply ( *) it by the background. | | | sing the alpha channel as a clipping channel fails when the foreground object is an already isolated CG object rendered against black with an alpha channel. |

| | You do not have to create an alpha channel for a document, paint will always create one for you, whether your original image had one or not. | | | In a 24 bit image opened in paint, the alpha channel will initially be defined as all white (opaque). | | | If you are viewing the blue channel, brush strokes will modify the blue only and so on. |

| | Alpha Channels |
| | In order to understand Alpha channels, you must first understand what a channel is. I will try to explain this by using an image in Photoshop that is being displayed in RGB mode. | | | These channel's store the colour information for each individual pixel and are produced automatically by Photoshop. | | | A quick explanation first, I am a webmaster in training and while I was trying to learn about alpha channels, in Adobe Photoshop 5.5, I could find very little about Alpha channels, although there are many good general Photoshop tutorials. |

| | Alpha channel |
| | The idea is to try to un-multiply the information stored in the color channels with the help of the known transparency information stored in the alpha channel. | | | This is important to do when you use Photoshop to produce alpha images intended to be used as decals in A:M because otherwise, A:M will think the image is not premultiplied as is indicated in the TGA files by Photoshop. | | | Although the alpha channel is said to contain the transparency information, in fact, it actually contains an opacity information. |

| | The only downside is that there are two ways in which alpha channels can be written to a file: premultiplied and "straight". | | | With the addition of an 8 bit alpha channel, bitmaps of this type become 32 bits per pixel. | | | The reason for this is that there is an optional fourth channel a pixel can have, namely its alpha channel. |

| | RGB Channels |
| | Just like in the RGB channels, black represents an alpha value of zero, or full transparency, and white represents areas where the alpha value is 255, which is the same as full opacity. | | | Channels are a resource that beginners often leave unused in programs with channel capability. | | | You can't flatten an image with alpha channels, and because layered images can't be converted, you'll have to delete all alpha channels before converting your image to a working file format like TIFF or GIF. |

| | Digital Juice Support - How do alpha channels work? |
| | Regarding color depth, it is always necessary to use 32-bit color depth (sometimes called “Millions of Colors+”) to have alpha channel support in your video or graphics. | | | Without 32-bit color depth, which is only available in a small number of codecs, files will not support alpha information. | | | GIF images support binary transparency, which allows any given pixel to be either fully transparent or fully opaque. |

| | Intro to PNG Features |
| | Whereas GIF supports simple binary transparency--any given pixel can be either fully transparent or fully opaque--PNG allows up to 254 levels of partial transparency in between for "normal" images (or 65,534 levels for the special "deeply insane" formats, but here we're concentrating on image depths that are useful on the Web). | | | But PNG supports alpha information with palette images as well; it's just slightly harder to implement in a smart way. | | | In general, though, only some of the colors need more than one level of transparency, and recognizing which ones is where things get tricky for the programmer. |
