Photoshop :: Selecting And Copying Only Black And Gray Of Picture
Jun 27, 2013
I am a Paramedic Instructor and want to clean up some heart rhythms to make them more neat and presentable for use during class. Below is the sort of image I would be working with.
What I would like to do is remove only the black and gray lines (when they print out of the EKG machine some lines have some gray in them) and place them on a neater cleaner background as below
(The image above I found on a website where the creator has 100's of EKGs that this has been done with, but have been unable to get him to tell me how it was done)
Also let me know if another Adobe product would be more useful in this situation. I have CS6 Master Collection so you know what programs I have available to use.

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 have several partially transparent GIFs.
I'm trying to layer them all on top of each other.
When I copy one partially transparent GIF and paste it on to the second partially transparent GIF the transparent section turns white and is no longer transparent.
Therefore covering up the contents of the prior GIF.
In short, please have a look at the three attached pictures, I would like to have all three on top of each other showing all buttons.

Gray / black halo around feathered transparency objects. The halo occurs where the solid area of pic feathers to the transparent.
NOTE: Image looks fine in Photoshop(CS6) but when placed in Indesign (CS5) a black halo appears on page
This only happens when image is an RGB Tiff and layer mask is used to create transparency. If image is saved as .psd then it is fine. Also when RGB tiff is converted to CMYK then this is also ok.
Ideally I could just start using psd format, but I have to handle a lot of images that are already in RGB tiff and it is time consuming to have to open and re-save all of these.
Photoshop CS5 RGB tiffs are still working fine.

I have a TIFF file of a scanned microfilm page of a very old manuscript.
The background of the black fonts is gray, and it makes the reading of the text very hard.
My question is: is there a simple way to extract only the black fonts of the text, or otherwise to brighten up the background?

Is it possible to copy or crop a portion of a layered picture and still retain the layers ?
If I copy merged I lose the layers and if I try to copy normally I only seem to copy one of the layers.

i have a simple block of text on a PS doc that is supposed to be black (i've checked many times and it's color =000000) but it looks gray on screen and prints gray. i checked opacity. it's 100%. i tried opening a new PS doc to see if somehow the doc itself was messed up, but i have the same problem in a brand new doc. make sure it wasn't a printer issue, i printed some text in MS Word and it got black just fine.

I thought I was copying a picture from my Elements 10 catalogue into a slideshow I was creating under "My Pictures". I now want to add text to it. I opened organizer, found the photo, opened full photo edit and got the message that the file was missing. I browsed for it, found it quickly in the my pictures slideshow file, clickec and got a message asking if I wanted to reconnect it. I clicked yes and got the message that it was in the catalogue. Even more disturbing, I got a message that all files were disconnected. Neither the Missing Manual nor Kelby even have the words reconnect or disconnect in the index.

Group, I just got CS4 and I am working in RGB and when I hit D to set default colors the black is not black... It is a dark grey. Basically the same if you take something that is black in a CMYK document and paste it into an RGB document. The black becomes gray. Can't figure out what color setting to change to set blacks as "Rich Black." Under Edit - Preferences - Appearance of black, it is set to Rich Black.

what would be the CMYK value for "70% Gray of 100% Registration Black." A teacher from school has asked me to print the type for a poster in that color, expressing it that way, and I'm not sure what he means. From my understanding, 100% Registration Black is C: 100, M: 100, Y: 100, K: 100. So how would the 70% change that?
In case you need some frame of reference, I'm working on a poster for a class that has to be printed in a particular way for a Photolithography class. I'll be making two files, each of which will have the info for one of the two colors in the poster. Those files will then be made into films which will be printed.

Art brushes are showing a grey version of what should be a Rich Black RGB 0, 0, 0,. Furthermore, expanding the art brush stroke and sampling the color shows the strokes "Black" is actually: 32,32,32, pre-expansion the RGB sample shows the stroke is 0,0,0.
Color Mode=RGB
Print Proof=NO
Document =RGB
Display all Blacks, print all Blacks=Rich Black
Options for Art Brush show art brush swatch is Rich Black but using eyedropper (within brush options window) and sampling preview stroke CHANGES swatch preview from Rich Black to Grey.

I have Photoshop Elements 8 and just recently it changed a bit. When on the active tab (any tab) the background outside my working space is completely black instead it's usual gray. I don't know how it happened but I would like it back to normal. I've attached my screenshot below.

I want to take some error warning from a computer program and change text, while maintaining the same shrift, color, etc.
So far, i've been using cloning. But if there is a great deal of letters, cloning becomes tedious pretty soon.
Just wondering if there exists some more elegant trick to do this job.

When I open a picture in photoshop, any picture, I see the picture and all around it is a background color. It has nothing to do with the picture or any work being done on the picture. This has to do with the color that comes up on the screen regardless of the picture. It was black and I hit something and it is now blue. I want this to go back to black.
I tryed clicking on the link below, selecting black for a background color and clicking and nothing changes.

I have a 3D drawing of a phone, and there seems to be a reflection or glare covering it and it is really annoying.
The screen portion is supposed to be white, as well as the buttons. The border of the black section is gray, as is the edge of the phone.

I have a blue shape with a feathered edge on a black background. The color transitions from blue to grey to black. I want to transition from blue to black without the soft grey line.

I have moved the library folder in OSX and then tried to start lightroom again pointing it to the new library location. Afterwards all Previews were replaced by grey squares (with color curves showing on the right, stars etc. but no image). It looks like the previews are not created but all the information are there
why when moving to the Developer rider, the Photos appear and i can work on it again. Thereafter it also appears again in the previews. S
Tried to optimize library but after 6 days of process ongoing i stopped with no changes at all to the library. Have about 60k photos in the library.I have tried the monitor settings but that makes no difference.This also happens with newly imported pictures,the ones that were appearing clearly in the library are grey at the next start of the project.running lightroom 5 with imac and latest osx.

Hopefully my title gets the point across. I've read numerous threads on here where people seem to have the same issue, but I've yet to discover a solution.
I recently bought a new pc and installed Corel Draw X5. When I export to eps and open the eps in Corel, the Pantone colors appear nearly black. This is also true for my clients, although I'm not sure what program they are using to open the eps.
It is worth mentioning that on my old PC I did not have this problem. EPS files I exported from Corel Draw X5 were fine. I could export eps files containing Pantone colors, and the Pantone colors would be there when I opened the eps file.
The settings I'm using under export to eps dialogue are the exact same settings I was using before:
Output colors as Native and PostScript 3.
I am running Windows 7 Home Premium SP1, and CorelDraw X5 15.2.0.695

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.
