How to reduce noise when there is only black and white?

Hi all

Total noob here, I looked everywhere without success (or I did not know the exact term), but how do you do that?

Basically, I'm trying to just extract lines and texts out of it, and the filtering and the exhibition did nothing for me.

As you can see below, the 'gray' color was made by points that are completely black. Is it possible to do?

So so so thanks in advance!

You can try the filter > noise > antiparasitics, then move to curves and drag the end of the highest point of the scale, a tad to deliver pure a pure white background.

  • printing color when you ask only black and white

    On my Deskjet 6500 all in one, I select black and white only when I print web pages, but it still prints in color.  The screen it displays in black and white, but on paper, it has color.  I use Google Chrome and maybe that's the problem, but I have no idea.

    jvias,

    You try to print in black and white all the time?

    If so, when you mention the screen to print in Google Chrome, down inside your should see 'print by using the system dialog box... '. (Ctrl + Shift + P) ». What to choose.

    When the next screen appears, make sure that your printer is selected and press the button "Preferences".

    On the next screen, it should open in the tab "layout". Then, press the 'Advanced' button and you will see an option there "print in grayscale". She should be currently disabled, but if you turn it on, it should print in black only.

    On the other hand, it sounds like it could be a problem with Google Chrome. Have you tried it in another browser and got the same result?

  • Size very large, even though it is only black and white

    Hello!

    I have a small question. I m of the Germany, I hope that you understand what I mean.

    Is it normal that the size of the image is very large, even if it's only a black and white image?

    I created an image with the 1920 x 1080 for my Web site. I created two variants.

    Alternative B is the one that I want to use. I created the A Variation to test, if the size is smaller.

    Here you can see that:

    Isn´t it's very strange, as the picture on the side left (alternative A) is lower, although it is one that has a lot more detail?

    Alternative B is only black and white with the black/white-filter?

    Can you give me an answer please, why the size is so important?

    Thank you! Best regards!

    -Max

    Yes, it's what I wanted.

    If you want to make the file smaller, try file > save for Web as a jpg file and explore the options.

    Be aware of the change in quality that you reduce the size of the file

  • E HP Print prints only black and white

    I print from an iPad on a printer Hp 5520, using print e. Hp previously was no problem until recently, it has now stopped printing in color and will be only only printing in black and white.
    If I print using the print on the iPad icon, I am still able to print in color, but I want to use the additional settings available in e print.
    I suspect that it may be to do with my an update of e print or IOS download

    I would appreciate any advice please.

    Hello R0dder5,

    Welcome to the HP Support forums.  I see that you do not want to be able to print using all options available in the HP ePrint app for your iPad.

    I'm sure that you already have, but my first suggestion is to check the settings in the HP ePrint app to ensure that it did not retain the setting.   If you choose the color setting is always print in black and white?  If so, please try to uninstall and reinstall the application.  You will have to start the activation process.  I've included the HP ePrint Mobile App FAQ document.  There the steps to uninstall the app, if you need it.

    Please let me know what happens.

  • 46HL900A - only black and white photo using Media Reader

    Hi all

    I recently bought a built-in digital LCD TVs from Toshiba model 46HL900A.

    I join a Western Digital (WD) TV Live Media Reader with the correct component input terminals. I know because I can see and play pictures, movies, etc. that can be found on the external hard drive that is attached to the WD.

    My problem is that it will only play/show in black and white.

    I tested the WD on another TV, and it works perfectly in color. I was told is not the working document, but that the TV might need to be set to recognize the resolution or something.

    I have been through the manual, but I don't really know what to change.

    Can someone help me please?

    Thank you.

    Hello

    I found your Toshiba page Australian TV:
    http://www.MyToshiba.com.au/products/televisions/led-backlit-TV/hl900a/46hl900a/specifications

    The TV supports color modes different system: PAL 50 / 60 Hz, SECAM and NTSC
    I guess that your TV is set to SECAM. Then try changing the NTSC settings

    Manual of use, you should find the description how to do this.

  • Photosmart 8450 prints only black and white with the new Mac with OS 10.6

    I just bought a new Mac with OS 10.6.  (former was OS 10.5)  Now my Photosmart 8450 will print only in black and white.  I installed the single upgrade on the site of HP, no change.

    Is there an other update I need?

    You want to disable automatic session opening, which may be why it behaves in this way.

    Go to System Preferences

    Go to security

    Under "for all accounts on this computer", place a check mark next to 'turn off automatic connection.

    In addition, I do not know if you set a password for the test account, but put something simple as 123 - just something / anything.

    Once that is done, choose log in the Apple menu, or reboot. This should bring you to the login screen where you can specify the account to enter.

  • How to remove the unwanted parts of drawing black and white line

    I scanned in a flower art simple black and white lines.  I would like to remove some of the petals in Photoshop.  How can I do?

    Thank youFlower003.jpg

    I would like to remove the petals from the background.

    1 method: with the select magic wand the white bg, select-> invert the selection and create a layer mask.

    The layer mask is a monochrome picture, transparent black, white is opaque and anything in between is more or less transparent.

    You can now select the layer mask, use the brush and black paint, where you want to have something white, removed where you want to have something added. It is non-destructive and works very well on your photo.

    You can use shift click to 'draw' the small lines to attach to the top. According to the clarification, it will take more or less time. As I said are non-destructive.

    Second method: you use the pen to draw the lines around your flower vectors. With little exercise, you'll very quickly and you can always adjust the curvature of your curve, by pulling on the handles of the curve. Here you can see how it works: drawing with the pen in Photoshop tools .

    When done with the pen tool, you can add the vector line as a vector mask. You can even refine your mask after finishing. I suggest, since a mask of course work at a refined mask.

    The flower should not be on a layer, a background layer. Basemap layers have no transparency. The two methods are non-destructive, so you can return to the original image or parts of it, whenever you want.
