Photoshop :: Gray Channel (in Gray Mode) Selection
Jun 7, 2011
I have another question about GREY images.
Example: CTRL+click on grey channel theoreticly (by my theory) make selection from white depending on its value. So cuting out must leave transparent greyscale image. But it don't (okey, it do, but changes black value):
The same selection inverted and filled with 100%K gives correct result: Is my "theory" about CTRL+click selection wrong? Becouse for my point of view, both ways should give same result.
How do I change the default toolbar background from dark gray to light gray in illustrator CS6? In the older versions, the toolbar backgrounds were light gray. It easier to read on light gray backgrounds. THe same question applies to Photoshop CS6. InDesign CS6 has light gray backgrounds.
My company is switching from ctb files to stb files. With the ctb file, we make concrete hatch with two layers. A top layer with the concrete hatch pattern and a background layer with a solid hatch patern. The ctb file concrete plots the concete hatch black and the solid background hatch light gray. I am using civil 3d 2013 and the hatch allows a seperate background color mask. I am trying to make all my concrete layers (Top of Curb, Curb Flowline, etc.) a certain color scheme, i.e. shades of green. I would like my on screen concrete hatch patern to be a green color with a gray background, but plot the concrete hatch black with a gray background. I can not figure out how to do this without making two layers. Is there a way to use one layer and utilize the background color mask to show on screen green and gray, but plot black and gray?
I draw comics digitally in Photoshop, working in Gray scale mode to reduce file size (I work very high-res). Is it possible to make Photoshop display certain layers in color, without switching to either CMYK or RGB mode?
Why does a black through white gradient created in an RGB document have a B channel that differs from the R and G channels? Â In 8-bit mode, only some of the "grays" have a mismatching B value and there seems to be more of them when the gradient is created by Gradient Tool than when it is a Gradient Fill layer. The difference seems to be 1 in the cases that I've seen. Â In 16-bit mode, I see the B differ from R and G by 7 at black, gradually reducing to 0 at white. Â Before someone says, "Why make a fuss about small discrepancies?", I'm asking why there is any difference at all.
I use the eyedrop to fix the photo in cs4 version. sometimes the eyedroper is stuck on grey mode and I dont know how to change it back to the regular mode where I can copy the color with it
When I'm working in guided or quick edit I'm fine but if I switch to full edit mode I lose the gray background and my workspace turns parent with my desktop showing through. I can still work on the photo but the workspace itself is changed.Â
I accidently changed the color of the background outside of my docked image from grey to black and can not figure out how to reset it to the default grey. The workspace dock color is grey until I dock an image and then the color surrounding my image changes to black. This is occuring in the Full Edit Mode.
When I select a color for text and shapes, the software defaults to shades of gray, although black and white are available. I use the eyedropper to select red on the pallette, for example, and the red box is framed. But the color sample on both the menu bar and the tool bar sets to gray. Is there a swicth somewhere that inhibits red, green, blue, etc.?  I even reinstalled the program, thinking I had a glitch--no change. The color selection had always worked in the past.
Just installed the LR3 software and updated to the last version. I inserted the SD-card with 12 pictures (jpg and raw) into the card reader but on the LR3 screen I only saw 12 grey rectangles. However, I imported the 12 pictures into a folder on the PC. The rectangles remained gray. With other programes I can see and open the pictures. My camera is a LX5.
I have photoshop cs6, and I was just wondering how to save a selection in channel mode. Â So for example (below), If i wanted to only copy the part of this picture that has white and the plant in the picture how would i do this? I've tried colour range but it didn't work so I am very stuck.
In both Photoshop and Illustrator the gray colors look brown. However, in Fireworks and other programs the gray colors look gray. Any color management settings to fix this?
When you fill with 50% gray in Pshop CS5 the fill has no effect when set to overlay – this is good!  CC on the other hand creates a 50% gray that is too light and when set to overlay it will lighten the image. This is a pain for creating noise or dodge and burn layers.
I just got my new PC (with a GeForce285 on Vista) and I installed Photoshop CS4. Now my problem is that the gray is not gray. If I fill a rectangle with a basic gray (128,128,128), it paints it with a "tan" color. When I "Save for Web & Devices" for example, the "preview" image is showed with the correct gray. I also "uninstall" CS4 and tried it with CS3 and it produces the same problem. The R,G,B colors seems to produce the correct colors and the B&W are perfect too...
I'm unable to use any colour effects..eg. i click on foreground colour, click red and it comes up gray, as all colours do, except for white and black... What can i do to fix this? as i need to user gradients etc.
I made a simple logo in pcs5 using RGB saving as jpeg then uploading into blog. The white has a grey hue. I calibrated my mac and checked my color setting in photoshop. I tried CMYK and saving for web and other devices. I did research online and I have had no luck. I even opened another logo, from a different blog, that has a simular setup to mine, into pcs5, saved it and uploaded to the blog to check and it too was greyish. The image is RGB white and looks completely white in preview and pcs5. I just uploaded the image here and it looks okay. Looking at it from an angle and I can see the shadow.
For some unknown reason, my backgrounds are opening with a gray background. All transparent backgrounds are now gray. Background and foreground are black and white so that's not the problem. This is frustrating me because I can't figure it out and I am sure it's something simple that I am overlooking. A
Looking for that standard gray that every cartoonist uses and I don't want to use the sticky stuff with an exacto.
I'd like to do it in photoshop but I can't find a brush/painting technique that 1.)doesn't get heavier as you go over the same area again 2.) stays with a regular pattern of dots, and 3.) doesn't require me to close areas to fill them (line theory demands that I break line to show depth so I don't want to close everything just to paint).
I've been playing around with this tutorial on aging a person. All is well except when I try to gray her hair I get a mess. Don't know what tool(s) to use. Could use some help since that is not part of the tutorial.
My client has an image of his hotel logo that is in black and white. Unfortunately he does not have the original vector art for his logo. He wants a copy of it in the color#999 for a brochure. How can I take the image and get this color.
I am building in Photshop CS a site template with several buttons, and moving back and forward between Photoshop and ImageReady.
I don't know what I did but, at a certain moment in time all my layer effects changed the "eye" icon to gray and the effects are not visible anymore EVEN if the gray eye in on. All the images with effects, now, look as no effects would be present BUT the effects have icon eye active (visible) but it is grayer in color than the other eyes.
I can't get out of this state, even if I delete the layers and recreate new ones. The effects are not visible anymore for any of the layers.
I have CS4 and all my gray tone have a strong red cast to them. However, outside of PS, the color looks just fine. I didn't have this problem with CS2. I have combed the internet looking for answers, but the only one I can find is "Calibrate your monitor!". the colors look right in CS2, and the only thing I have changed about my system and/or monitor is my version of PhotoShop (CS2 to CS4).
When I have a layered RGB image and change the mode to Gray, PS asks whether I want to flatten the image (thus losing layer information). Why is this, I don't see why this is desirable or common?
i havent used photoshop in a while but i whipped it out because i have a project to do, and well my gray is... like greenish, its retarded and it annoys the living hell out of me! Like if i save the file it comes out as a normal gray but within photoshop it is freaking greenish, its wierd, even if i import an image it comes in green! Ill show you a link of a couple things i think are odd,
Working in CS5.5, When I open my Photoshop the main work are in transparent. I see the menu and tool bar, layers etc. but the desktop shows through and it is very distracting. How do I get a neutral gray background?
Accidentally pressed some keys on keyboard, so now I see all layers in gray color, except top layer, that is green, and stays so, also when I draw something, it shows in gray only, though color channels are ok, image mode is RGB and there are no blending options applied.
