Photoshop :: Relationship Between Layer Mask And Channel That Created It?
Sep 13, 2013
Suppose I have carefully made a selection and saved it as a channel. I then use that channel in an adjustment layer as a mask. I also use the inverse of that channel in another adjustment layer.
Â
At this point do I have three separate masks inside photoshop: the original channel, and two others that are layer masks? If I then see that the original mask wasn't quite right so I do a refine mask on one of the layer masks. I haven't, I think, changed the original channel, right? But I'd like to use the inverse of that channel in the other adjustment layer.
This gets pretty messy pretty fast, especially because I'm working on a very large image. After I modify the layer mask should I save it off as a separate named channel (it doesn't seem to be accessible unless the layer it's on is active) and then invert that, save it, and reload it as the layer mask for the other adjustment layer?

(CS3) I have a raster layer that has some semi-transparent pixels.
I'd like to make the layer itself fully opaque, and move the contents of its alpha channel into a layer mask.
(If possible, merging the alpha channel with what I have already placed into the layer mask.)

when I added a layer mask to a layer, it would display in the palette as the alpha channel, which was very handy. Now, when I add a layer mask, it only appears as the mask icon; i.e., gray square with white circle in the middle. I have no clue what I did to change from the one to the other, but I would certainly like to get the alpha representation back!

I am making selections of models off of a white background. I use the quick select tool and refine to make a clean selection. I go in and use the clone tool to remove the "halo" that is still there to make a super clean selection with no light bleed on the model. I put a black layer underneath to make sure that I got all of the remnants. I save the selection and turn it into a channel. I apply the layer mask and everything looks good. I flatten the image and put it on a white background (this is the desired form of delivery for client) Image saved and closed. When reopened, I make a selection using the channel and there is a distinct halo effect still present. I have tried making the selection and going over it a couple times with the brush at 100% and it works a little bit, but not entirely. I have already spent a lot of time going through cloning things out so it looks good, delivering the images, then they are sent back because of the halo.

I follow a tutorial about making a pattern and she tells me to paste. I need to have the right channel marked. I do have the black dot in the right channel, and the channel is marked. I have a mask selected. I click paste, nothing happens.
Â
It's a brick and I'm planning to have 3 channels for it. Light, dark and something in between recolorable. I even saved a selection and then loaded it onto the correct channel. I tried to delete the extra mask channels hoping it was still saved. Then all knowledge of any maskes seems to be gone. As you can see on this picture I have all the channels there with masks, but it's still not being saved. I load this into another program and channels is nothing but 3 different colors all over. There is no selection. When I'm trying to save this as dds It says I have 3 alpha channels, they are suppose to be red, green and blue! [URL] ........

I've been having this problem since Photoshop 3.0. In the event my current version of Photoshop saved preview thumbnails, and my OS would display them, there would often be portions of the image missing. I noticed that there was usually a mask or channel matching the missing portion, and deduced that Photoshop was arbitrarily masking the preview, making them useless even in the cases where I could see them.
Â
Don't bother responding with "Adobe does not support thumbnails" or something similar. Any work around that does not involve deleting all masks and channels "just in case" one of them randomly spikes the thumbnail. As mentioned, it seems to occur randomly; I have hundreds of tiles with scores of masks and channels that produced clear thumbnails. Perhaps one in twenty grabs a random alpha channel and obscures the preview. I'm getting tired of wasting HD space saving a PNG clone with every PSD to save myself the hassle of opening up dozens of PSD files to find the one I need to work on.

I'm interested in making a Saturation Mask. Actually I want to extract the Saturation Channel.I know there's HSL / HSB Plug-In made by Adobe which is able to do so.Yet, I'm interested if there's an option creating it using the Blend Modes (Just like adding a Solid Black Layer in Color Mode creates a Luminosity Mask).

What I want to do is to have an adjustment layer that is a reversed, black and white image. I initially thought to merge B&W and reverse adjustment layers, but read that an adjustment layer may not be the target of a merge. Is the way to accomplish this to fiddle with the B&W adjustment layer sliders somehow?
Â
I like how the black and white displayed image of a given color channel looks, how can I export that channel into a layer?

My subject line pretty much sums up what I want to ask.
The thing is I've learned how to do both of them, but every textbook exercise I've done regarding one I found out that I can pull off with the other too.
Are they simply two different mechanisms for doing the same thing?

Once I use a Clipping Mask on a layer is the entire document covered in a mask?
Â
And/or is all the artwork from then on inside the mask?
Â
I've read about how to add and how to remove art from a mask. I've read about how to make and release and lots of other things.
Â
So, then I went and found a lesson that contained the use of a Clipping Mask.
Â
I am suppose to Select the main shape and "just" copy it and move it down (doesn't say rather to Paste in front or back but I assumed in back ~ not that it has mattered thus far)
Â
However, while making the main shape I used Gradient Mesh and used an Offset to create a "replica" and so when I go to Select the main shape the mesh is selected and so when I Paste (in back ~ seems most logical) and then move it down the details such as the colors of the Gradient and other such things are visible in front ~ ??
Â
So, I have been trying to abate my problem in lots of different ways.
Â
I have tried using the Pen tool to draw behind the main shape, I've tried making a New Layer and placing it above and below and inbetween the main shape layer, I've tried adding the artwork to the Mask ... I've tried everything I can think of and I've been through many an article in the manual and FAQ's to no avail.
Â
I suppose, what I think I need to know ... is, how ... how on earth do I draw behind this main shape? Am I not able to do it because I am not getting behind the Mask?

Is there a way to change the functionality of the layers so that when a new layer is created or a layer is duplicated that it automatically is created below the selected layer? I always organize my files with elements at the top of the document at the top of the layers panel and have them in decending order (unless there is a reason for an object to be above another) so that it is easier to navigate the page. Right now this means I spend a lot of time moving layers up and down which gets rather annoying. I believe I saw at one point that there is a key command for duplicating a layer below the existing one, but I can't remember how anymore. ability to make a blanket change in preferences.

the key functionality lost is the ability to use the previous layer mask for a new layer

I need to adapt a design to a billboard; it was originally created by our parent company's marketing. The billboard company just informed me that I need to incorporate a bleed area and the document does not have that. I think it's using a mask on the items that will need to bleed, so I need to find the masking box and expand it to meet the bleed. But since I did not create this document, how to find it and it's difficult to reach Marketing. Is there an easy way to find the mask, or make it visible?

I can do one or another, but both at the same time? It is annoying because a mask selection turns into layer selection when you select a second layer/folder.

Is there a difference between selecting your layer and clicking Add Layer Mask Icon versus having that layer selected, hold down ctrl and select Add Layer Mask Icon?
Also regarding working in Lightroom, if I modify a jpeg, select another image from filmstrip to work on and then go back to the first image for more work, are those actions degrading image even though I never physically save and close.

I've often been annoyed by the fact that that I need to go into the layer panel each time I need to switch between editing a layer and editing it's mask. Surely there must be a way to do this with a shortcut. I found a way to disable the layer mask in the shortcut menu, but this is not something I need to do that often. Switching between layer and layer mask, however, happens all the time - at least in my workflow.

I can't figure out how I can use a text or shape layer as a mask for the layer below. See the example attached and you will know what I mean. (I created the example with simply cutting out the text outline from the white box).
Â
I need the text to be a mask and I need it to be editable as text. Don't know if this is possible, experimented with clipping masks but I cant make it work.

Basically exactly how layer masks behave, except I would like to be able to have full non-destructive editing control over the masking layer (e.g. have it as a smart object). The problem with layer masks is that (AFAIK) only destructive editing is possible.
What I'm after is effectively the same as what a 'luma matte' does in After Effects. Is this at all possible in PS?

I could have sworn that in previous versions of Photoshop, before version CS4, that if there was a link icon between the layer thumbnail and the layer mask on that same layer, if you move one or the other, they both move. In CS4, how do you move the layer pixels and the layer mask at the same time so that they stay lined up?

I have been trying to copy a mask from one layer to a new layer in Elements 11. I can do this in CS3 by using alt and dragging to the new layer. It doesn't work in Elements 11. Is this feature unavailable in elements 11 or is there a different command? there doesn't seem to be much point in spending all that time making a complex layer amsk and then being unable to use it on another layer.
I have to give a tutorial on layer masks using both CS3 and elements at the Camera Club!

I've made some selections by color range to recreate a scan and have them as channels. When I save them as a pdf while veiwing only the channels the result is a blank pdf. I'm thinking I should convert the channels to layers but can you. It seems I've done it before.

I'm trying to blend a photo with a background color. I select the new layer mask (selected), I select the gradient tool (color into transparent), and then draw a line to fade the image layer into the background later and it does nothing. Why isn't this working?
