Photoshop :: Luminance Masks - Apply Channel To Adjustment?
May 11, 2013
When I try and apply a channel to an adjustment of my choosing, I get a red mask across the whole image and the alteration is global as opposed to the selection of the mask if that makes any sense? [URL] ........

Lets say I have an area of a picture to which I want to apply a adjustment layer such as Hue/Saturation. I select the area and create a mask. I then apply a Hue/Saturation adjustment layer.
The problem is that the adjustment layer affects the whole image rather than the masked area.

In PS CS5 when Adjustments panel is selected un the Windows dropdown menu next to the adjustments panel tab there is a Masks tab. This is not the case with PS CS6 Beta. Why is this the case? Has Adobe excluded the Masks tab? I could not find the Masks tab under the Windows drop down menu?

I am having an issue with clipping masks only affecting the intended layer no matter what color background I have on.
For example - I have some lettering that I want to apply a gradient map adjustment layer on. In order to only affect the type layer I hover between the adjustment layer and the type layer while holding Option + click to get the double b+w circles to clip it.
When I clip my ad layer, I don't get my effect. The only way I see the adjustment gradient effect is if I unclip my adjustment layer, but then this affects my ENTIRE background rather than just the type.
Is there a trick to keep the adjustment effect without affecting the rest of the layers no matter what color background I have? Adjustment gradients seem to work best on black backgrounds only. The problem is that my original document has a red background so I HAVE to clip it in order for the gradient not to affect my red background. But even on a black background, I have to unclip the ad layer to see the effect. This is weird.
I could flatten my document and extract my type with all its effect glory and just import it into my original doc, but selecting and extracting blurred type would be a big slap on the head.

One thing I have never understood is: why use layer masks and adjustment layers, instead of simply creating a copy of the subject layer (the one I want to make changes to) and experimenting with that? It's quick (Ctrl-J), I can do it as many times as I want, I'm not affecting my Background layer. If I like the changes, I can keep them. I can switch the copy on and off to compare with the Background layer. I can do any type of blend or combination I desire. I can insert Gradient layer(s), select any part of the copy and (Ctrl-J) create a new layer containing only the selected part. I can adjust size, rotate, do anything.
It almost seems that "layer mask" and "adjustment layer" are mainly another layer of terminology; how they are intrinsically different from or superior to working with copies of the Background layer?

this worked until yesterday. I didn't install any software on the pc or change any settings that I can think of. I'm using photoshop cs2. I've rebooted the computer several times and I've quit/restarted photoshop several times.
when I create an adjustment layer, I cannot paint black in the mask area. I can fill with black and paint white. if, after filling black and painting white, I press D (to swap foreground/background colors), I can paint, a paintbrush thing shows up in the history, but it won't change. if I press D again, and paint some more white, it shows up in white. likewise, if I choose black another way (eyedropper, setting rgb to 0,0,0), it behaves the same. likewise, if I don't start out by filling black, and I just try to paint black on the white mask, it behaves the same (doesn't work).
if I create a new layer, I can paint black on it. If I switch to the pencil tool rather than the brush tool, I can pencil black into my adjustment layer masks.
any suggestions?
or what info can I get for you so you have a good place to start?

Say I have an image where I'm attempting to extract a mask from and I've found that one of the channels will serve as a good starting point. Further suppose that I have found that I want to increase the luminance level of pixels in the range of 60 - 65 by 10 luminance levels each:
i.e. all pixels with luminance values of 60,61,62,63,64,65 would, after the operation have luminance values of 70,71,72,73,74,75. Is such a thing possible with Photoshop?

I ran to a little trouble using photoshop today. I wanted to get rid of the "adjustment layer" but leave the effects.
For example:
I have two layers and I want to apply the adjustment layer effect to them. I don't want to leave that "adjustment layer" on top of everyone. I can't use groups because my real project is too complicated. By the way, applying the adjustment layer to all of them means all the layers remain an image but they have been modified (for example: color, black and white, etc.).

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.

WIndows 7 x64 | PS CS6. Just now while attempting to edit a Channel Mixer adjustment layer's creation dialogue settings, about 15 browser windows (not tabs but individual windows) trying to load Adobe docs all popped opened simultaneously.Killed Firefox's process and went back to PS.Every time I went back to PS though, it would happen again, when I clicked in the Channel Mixer settings.
Got out of the loop by mashing the ESC button as I switched back to PS, which successfully killed the Channel Mixer dialogue.I've seen this behavior in PS for about 4 versions now, but never this severe. How dysfunctional.

I am trying to re-edit some of my birding photos (CR2 raw images). I have difficult masks that were created in LR3 and took alot of time due to feathers on a complicated background. I do not want to have to re-mask everything in LR4. When I have imported my files to LR4 the original LR3 mask is still present. However, the sliders for Temp, Tint, Hightlights, Shadows, Saturation, Noise, Moire and Defringe are missing. I want to do localized noise control to keep feather sharpness so I need the Noise slider.
If I work on a photo that had no LR3 mask all sliders are available. If a mask from LR3 exists I am missing sliders. URL...

I'm trying videostudio pro x5 and it looks very nice, but I have a problem that I think will lead to be a big limitation in the potential this software has, so I guess this is a bug or maybe I am not using it in the right way. I just hope is not that way by design
Anyway, the problem is that when I apply a filter to an animation or to an image (like PNG) that has alpha channel, I can see the filter coverin the whole frame if the clip is in the main video track, while if I move it to the overlay track the filter will only stay inside the picture, for example I've tried this with the lens flare.. please see this image (situation 1 on top and then situation 2 bellow the orange line):
I'd expect the lens flare to go over the transparent area of the clip so that it will be overlaid with the "background" main video track, but it is not. This is just an example but for example the same happens if I apply the lightning filter to a text filter or to a png..
I also have a similar concern with the free TitlerEx plugin that I've downloaded after registering: if I put it on an overlay track I can't just have the text with transparent background overlaid to the main video track.

How do I apply an edit to every file in a folder? Every time I need to do this, I end up flailing around for 10 minutes before I can finally get it to work. Or, sometimes I give up and manually paste the copied settings to each file one at a time. It seems a no-brainer that "copy settings" followed by "paste settings" to all files selected would do the trick. Or "copy settings" foillowed by "Sync settings." But it doesn't work.

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?
I like how the black and white displayed image of a given color channel looks, how can I export that channel into a layer?

1) Take a color image and apply a color-shift local adjustment to a portion of the image.
2) Convert the image to B&W.
Result -- The main image is converted to B&W, but the local adjustment doesn't change, i.e. it's still colored. Here's a trivial (and not-realistic) example of what happens:
My goal is to adjust the colors and the apply the B&W conversion to the entire processed image, not just the original piece. Is there a way to do this? I feel like I'm missing something small and easy.

How to Apply adjustment layers to multiple layers that have different blending modes and keep the colors the same as the adjustment done?
I work in Animation painting Backgrounds. My files are sometimes upwards to 200+ layers.I will use adjustment layers to quickly balance colours and constrast on top of those many many layers.
The only way that I know of how to apply adjustment layers it to every single layer ( by applying I mean I need to get rid of the adjustment layers because we cant use them in production but i need the new colours be applied to all layers underneath ) in a psd is to manually do it By duplicating the adjusment layer 200+ times and then merging each layer to one of those adjustment layers so that that layer can take the adjustment layers effect permanently.
The issue is that Within Those 200 layers I have some layers set to Multiply or OVERLAY. IT obviously wont apply the adjustment layer properly to those layers because those layer blend mode affect the layers under them. The colour wont be the same anymore in the spots that had the multiply blended mode.

I have 2 adjustment layers up top. I need to get rid of them by applying them to each layer! I cannot merge any of the layers. We need all those layers for production.I can apply the adjustment layers manually and this works GREAT for all Layers set to normal. THey take on the colour change just FINE.
However, The issue is that layer 6 and layer 4 are both set to mutiply and this screws up the colour once i apply the adjustment layers to each layer manually...
How can i apply my adjustment layers to a file like this with some layers being set to multiply while keeping the layers exactly the same configuration and The new colour taking effect exactly how i looks before i apply the adjustment layers? Now the simple solution is to merge the multiply layers to the layer that it affects HOWEVER I NEED those multiply layers to be separate!

I use a lot of adjustment layers and they're often applied to the previous layer. Is there a keyboard shortcut to automatically "Use pervious layer as clipping mask" without going through the dialogue box or manually applying in the layers palette(Option-click between layers)?

I am having trouble with using my layer masks. I can use the masks that are hidden (shown with black screen) and apply them with the white brush, but I cant get white or shown masks to be taken off with the black brush. Sometimes, not always I have trouble adjusting the opacity of white masks. I was playing around with actions I downloaded and after applying three actions to a photo, elements froze on me. I read about trashing preferences, I dont know what that does or means but I tried to hit cntrol alt shift when photoshop was opening and nothing happened. When it first opens it shows I can install the new inspiration browser ( i dont know what that is either) thinking it was a required update I tried to update and it gave me an error message, something about the installer has been mis-configured.

I am a screen printer and I print my separations from Photoshop. I routinely work with multi channel files or RGB files with additional spot color channels. I have created actions to place my registration marks, re-size images, etc to get ready to print but I manually have to create the text labels for each screen if they are missing from the original artwork.
The files I work with have channels named as "Base White, Red, Green, 284 Blue" etc indicating the ink color. What i would like to be able to do is click an action that would copy the text from the channel name and insert it into a separate or each/all channels near the top of the file so that when I print each positive it has a corresponding label for ink color.
I am not sure if this is even possible, and I am limited on my knowledge when it comes to actions and have pretty much got lucky in the past getting them to do what I want without unnecessary steps.
On my registration target action it creates a new channel with each individual reg mark then combines them into one separate channel in which I just copy the contents and select all the ink channels and fill with black to make them appear, i'm happy with the steps it takes as it isn't too much trouble and if this could do the same with labels I would be happy with that.

I'm working on a chart that displays and names a couple hundred color swatches. I have all of their color data in a table, and I want to arrange them by hue and lightness, so I applied the Rec.709 coefficients to my data. This arranges my colors into a natural gradient--except for the reds, which have some glaring misplacement. why .709 coefficients do this, or what coefficients I should use instead?

Is it possible to extract raw luminance values from raw image files? Actually, a de-Bayerized flat matrix would be ideal but could (? maybe) deal with a 3 layer RGB matrix -- rather like the output from dcraw, only in PS. Preferably without gamma applied.
What I'd like to do: I'd like to use image stacking for exposure accumulation using "summation" but find that highlights blow out readily. Right now the workaround is to let the highlights go and bring them back with HDR from one (or more) of the original frames, but that's seriously clunky. I'd like a "scaled summation" where a luminance-dependent scaling factor is applied in the sum. I don't yet know how to get there from here in PS (there's a megaclunky way involving dcraw, Matlab, and a stacking program ...), but it seems to me that the first step is to get the luminance info.

I'm trying to get every pixel value in the black square to 000, and all the white pixels to 255,255,255. I've started out with an 800 pixel square solid 255RGB square and then applied a solid 0RGB black square over the top in a new layer, but as can be seen by the color pickers PSCC is doing an unwanted luminance blend around the edges.
Is there anything I can do to stop it and get a solid black square on a solid white one?

I have a series of grayscale images that I'm trying to adjust so that they all have the same--or at least very similar--contrast, luminance, and brightness. When I try to adjust these things, it's always measured relative to the images's starting state rather than to anything objective.
