I'm working on a RGB file and I accidentally hit 'Ctrl 3' which brought up the blue channel - I really liked the image in that channel and I was wondering if it was possible to print it - as it's black and white it looks quite moody and interesting..
View 4 RepliesI 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.
View 5 Replies View RelatedI've been trying to change the brightness/contrast of a single channel (red channel, etc.), but it always applies to all of them, even if I select only one of them. I havn't been able to find and option which will allow me to work with them individually.
View 5 Replies View RelatedI am learning about using channels as a mean of channel masking in CS5. The instructor on a dvd starts with a general understanding of channels. Within the first 2 minutes, I can't seem to replicate his instructions.
Here are steps I take to look at the individual channels Red, Green, Blue.I invoke "Channels" in my layers palette. What appears is the RGB, Red, Green, Blue Channels (with the eyeball showing in each of the individual channels).The instructor says to click on each of the channel and you will see the appropriate a tone map of each individual channels.
When I click on lets say the red channel, nothing happens ... all of the layer eyeballs are still on and I get no individual tone map. If I deselect all of the eyeballs, then I can get the individual channel tone maps.
I suppose that the instructor is using a shortcut key to invoke each individual channel tone map, but he doesn't explain it.how to get an individual tone map directly after opening up the channels palette, without having to manually remove each eyeball.
I was wondering if there was an easy way to view individual color channels (Red, Green, Blue) in the viewer, and if so what the shortcuts are. I know you can do this simply in flame but can't seem to find a way to do it in Smoke.
View 3 Replies View Relatedhow to adjust the curve of individual RGB channels. I am assuming the LR4 Tone Curve works like the PS Curves dialog with the channel dropdown.
To make adjustments to individual points on the tone curve, choose an option from the Point Curve menu, click the Edit Point Curve button , and do any of the following:
Choose an option from the Channel pop-up menu. You can edit all three channels at once, or choose to edit the Red, Green, or Blue channel individually. When I click the little icon in the lower right corner of the Tone Curve panel, the panel shrinks so that I don't see the Regions sliders. If I click again, they are visible again. I can't find where to select one of the three indvidual channels.
The Help refers to "the Point Curve menu." Where is the Point Curve menu? Is the Point Curve different from the Tone Curve?
If I right-click (Windows) in the curve dialog, the context menu has a Show Info option. I click it on/off and don't see any change or any info. Where should I be looking for info?
Ok, I am modifying a graphic using photoshop CS, and I am creating a spot color/alpha channel on a greyscale image which I am then placing in Quark 4.0.
The problem is that I can't get the image to separate out just my cyan plate when I distill the Quark document.
Is there a way that I can save my channels so I just get cyan and black, or do I need to switch to a CMYK image mode?
I have drawn a small machine of 3D components in the model space. Each component is placed on a separate layer so that i can isolate each component. Now I need to print machine drawings for each component in paper space. I can open a view port in the paper space and freeze all the other components not needed to get the view of the one component. the problem is that on the next paper when i try and put a view of the next item by thawing the new item and freezing the previous one, this affects the first as well. What is the best way to isolate individual components from a 3D model for printing machine drawings?
View 2 Replies View RelatedWhat 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.

I 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?

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???

I 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?
I have a question about channels.
View 5 Replies View RelatedMasking 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?
Many 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 RelatedI 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!
View 3 Replies View RelatedUsing 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.
In my Camera Raw 6.7, when using the Tone Curve, the RGB channels are grayed out and can not be switched on, probably because the Raw Defaults are missing.

View 9 Replies View RelatedWhy 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 RelatedIn 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?
I 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.
blending 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 RelatedI 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?
alpha channels, and how to use them?
how can i apply the alpha channel to the original to get all the green stains out?
Been 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 .
I 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...
