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.

May 8, 2006I am trying to edit this picture, and i find my desired results by manipulating the channels (removing the blue and leaving the green and red so it looks as if the whole thing has been tinted yellow), but when I save it as a JPEG, the yellow is gone, leaving all RGB. How can I keep it with my yellow?

Mar 27, 2003I guess sometimes teaching newbies like me is annoying. I could take the easy way ripping like most of the people does, but i do really want to learn, and i have a question, so if someone thinks tht spending his time teaching a fool newbie is something worth, thr it goes...
I know when we have an image even it is using "RGB" or "CMYK" collor mode, it is divided in channels, red, green, blue and so... this i can understand quite clear, but wht exactly is an alpha channel??? wht collor it represents??? Wht is it for??? Is there an article tht i could read about it??? I can manage it well, but i'd like to know it's concepts..
Photoshop :: Channels
Jul 20, 2004I have been using the Total Training series, and am ALMOST complete (Just gotta go over the Typeface tool area and go over the Bonus disc material)
One area that Deke (the host of the series) didn't get into much was Channels. Hopefully I would like to state how I see them, and if I am incorrect in any way (or if you have useful information about channels), you could pipe in and let me know! Thanks.
Ok, so channels are dependant on the Color Mode you are in, right? If you are in RGB, then you'll have 4 channels. Red, Green, Blue, and the channel which controls them all, called RGB. In CMYK color mode, you'll have 5. Cyan, Magenta, Yellow, Black, and the control channel 'CMYK'.
Each channel, aside from the control channels, are a Grayscale mapping of that color's (WHAT?) in an image? It's Lightness? Saturation? I know it couldn't be Hue, because that's determined by the collective color from each channel put together.
Also, what is the point in ADDING channels? I thought that it would be nice if you could add a channel which affected the layer via some kind of adjustment, but that is merely the adjustment layer feature (with mask used in order to define intensity of the effect on that layer) So what is the point in adding channels?
Photoshop :: RGB Channels
Jun 21, 2008Masking using Channels and tried on one of my images.
When i select "Channels" option, i am getting a image which looks like looking through a RED, BLUE and GREEN filter. It is not showing the images in various greyscale modes as shown in the tutorials. There is a red or blue or green color cast on the image.
Is there any setting i need to select when using these options?
Photoshop :: Channels
Oct 30, 2004Many times when I am doing something in Channels the black and white image(s) look better than if I converted the RGB image to grey scale. I have been experimenting with no luck. Is there a way for me to select one of the red, green or blue images and make it a final image that I can alter and save in PS?

View 6 Replies View RelatedPhotoshop :: How To View Different Channels
May 14, 2013I am trying to convert an image that I took in SlideBook using fluorescent dyes to label proteins on a cell. The original image has two channels (red and green) with different intensities for each which correspond with the amount of each respective protein present. The problem is when I open the image in PS and convert it to RGB mode, all three of the channels have the same intensities so I get a black image. If i vary the contrast I can see the image but it is in black and white and the intensities of each channel are the same so I am unable to separate the two colors. I need to be able to see both channels (red and green) with their original intensities but I cannot figure out how!

Feb 17, 2013Using CS5 - up until yesterday was able to select RGB in Channels panel separately.
Today when I go into channels I can select Blue, Green or Red separately, but when I go to select RGB on it's own, it won't - it highlights that and the three seperate channels. I can turn the 'eye' icon on and off all of the others but not RGB.
Photoshop :: RGB Channels Grayed Out

Apr 17, 2007Why is it that in an RGB colored red rose, the red channel is very light in color and the blue and green channels are very dark (near black), even though there is relatively little blue are green in the colored (RGB composite) version of the vibrantly colored red rose? This seems to be counter intuitive. When I look into the red channel, I would expect to see dark density to reflect the dominance of the red channel and lightness in the blue and green channels to reflect their relative absence in a red rose.

View 4 Replies View RelatedPhotoshop :: Paths And Channels
Dec 23, 2002In some tutorials they make selections and store them into a channel. In others they use the pen tool and store the selection as a path.
Are these two ways or doing the same thing or they have different uses?
What are the pros and cons of each one?
Photoshop :: I Want Grayscale, But I Still Need My RGB Channels
Jun 10, 2007I need to convert an image to Grayscale in CS2, but I need to retain my RGB channels. I need them because a special bump map tool that I have, which also converts images to DDS format, requires them. And I need to make my bumpmaps with this tool because of the special format that dds files require for the game I am using these textures in.
I've been using the Photocopy filter, but I feel it leaves the image a bit "dirty." I'd like a clean Grayscale conversion.
Photoshop :: Alpha Channels
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.

View 1 Replies View RelatedPhotoshop :: Extract, Channels
Dec 19, 2006I have a picture I'd like to Extract. So far I have lightened it and cropped it. I have also had a look at Russell Browns QT tutorial, but I don't quite understand about channels. As far as I can see, I would benefit from using the Red Channel perhaps, but I would like your opinion on it.
Also, while I do Extract it, I'd like the image as large as possible, but once I click "Extract", the picture becomes much smaller. If I keep it as big as it is now, it will be OK, but probably not if I resize it.
At the moment, the picture is quite big, and I don't know how to get it down in size (kb) and still keep it physically big enough for you to view it. I know I can save for web, but even then, it won't go down to 75KB. What Width etc. should I set it to?

Photoshop :: Beveling With Channels
Nov 15, 2002Been messing around with using gaussian in the channels and then applying the texture to something, but this grainy texture keeps sneaking in.
Anyone know how to get rid of the "bumps" in the middle? I made a square, blurred it, messed with the levels a bit, then I contracted the selection to darken the center. Just in case that information might help .
Photoshop :: Jagged Channels
Oct 9, 2004I was playing around with lighting images today by first creating an alpha channel, blurring it and then applying the lighting effects filter to it. For some reason after applying the filter I get jagged edges everywhere. When working with the channel, i did invert the selection and then clear it...

Jan 10, 2005I am unable to use the Search in Photoshop Help. This has not been a problem in the past. I did however recently load SP2 but really don't remember if this feature worked following that download.
Also, while doing a tutorial one of the steps indicated that the channel visiblity should be turned on and used. When I went to the channels palette this was not available. I have Photoshop 6 and it's quite possible that this feature came later. Is there anyway of changing the visiblity of an individual channel.

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 :: Maximum Number Of DCS Channels
Apr 26, 2013What is the maximum number of DCS channels that can be used? I have a file I saved as DCS 2.0 with Black and four spot channels, no problem.
When adding a fifth channel, that channel shows with a white background even though I made a selection of only what was being used and pasted that in.
Photoshop :: What Is Max Number Of Channels In DCS File
Aug 29, 2013I have a file with Black and 5 spot channels. When creating a pdf, only the last channel appears and all else is white. If I delete one channel, any channel, if appears with all plates showing. I created a DCS file, added one new spot channel at a time for whatever art was printing in that channel. When I go past 4 channels, that's when things get strange.
The file prints correctly, however will not appear correctly in the PDF. And, I need to send a correct looking PDF to client.

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).
