Batch Black and White Conversions

Hi,
I've been trying to use the life and stamp tool to batch convert some images to black and white (using the monochrome mixer). Basically even trying to convert one image that way freezes my machine (powerbook 1.67 gH, 2 megs RAM) and I have to reboot.
Anybody have any suggestions....I guess this kind of batch conversion w. the lift and stamp tool must be very processor intensive? Even so....you'd think it could handle one! I did have some other adjustments on the image....filter, levels and sharpening.
Thanks a lot!
Lisa

Hello, lisa & scott
scott has some good advice for you except for one statement he made which is misleading and has been circulating around the mac internet news forums misleading readers and I would like a chance to squelch it once and for all:
Quote: "but really, this repair permissions action is starting to have a bit of "voodoo" status in OS X troubleshooting circles. i'm not sure that it will help with your slow-downs in Aperture though."
For the record, my recommendations are Apple text book troubleshooting regimens (Mac OS X Support Essentials, Owen Linzmayer, ©2006). I am an Apple Certified Pro Trainer, I help maintain the numerous mac computers in the classrooms where I teach. If this is voodoo, as scott is suggesting, then Apple has been totally wrong in recommending this systematic methodical troubleshooting regimen.
How do we answer any question in any forum as to why is this problem is happening to you? and not to others? or, maybe to others? There needs to be a starting base or instructions if the problem is not a known issue or if the problem cannot be verified on the systems on our end.
The recommendations I have made are painless, harmless and the least invasive. It will dump a lot of temporary files, font cache, get the OS X talking to it's respective files, directories, volumes, etc. it is the first step in finding out if the problem is
1. User-Related
2. Software-Related
3. OS-Related
4. Hardware-Related
Among other things some application problems can be OSX based and not the application itself. Repairing Disk Permissions in Safe Boot Mode is an excellent starting place.
As an example, many times when an application freezes or gets the spinning beachball, clicking on the Desktop and Repairing Permissions will clear the freeze and the beachball and quickly get you up and running again.
Besides this lisa, scott has given you some very good advice
Take care you two
love & peace,
victor

  • Black and White conversion issues going from LR to PS

    When I take a black and white image directly from Lightroom to Photoshop using "Edit in Photoshop", the black and white conversion doesn't stay true. My image, once opened in PS, is mostly black and white, but has green and magenta casts running throughout. Anyone know how to resolve this without just gray scaling the image again once in PS?
    Screen grab from LR on the left, and PS on the right.
    Thanks.

    Well, it looks cyan to me. Here it is with saturation boost - assuming the OP made the screenshot correctly, assigning the display profile:
    In any case, the Photoshop bug is well known and well documented, showing up as cyan shadow banding in ProPhoto files, when GPU is set to "Normal" or "Advanced" mode.
    I'm not saying the display profile isn't involved, it most certainly is. The whole issue is the conversion into the display profile. And it also shows to varying degree with different display profiles - sometimes just subtle cyan bands, easily missed until you look for it, other times more pronounced and with secondary red banding (like here).
    It also happens with sRGB as display profile. So the bug is real, no question about that.
    What's different here is that there's cyan also in the highlights. But that could be the screenshot - or it could be "just" a bad display profile. I'm not ruling that out, just pointing out that there is a more likely explanation in this case.

  • Black and white conversion of tiff files in pse6

    I like the "convert to black and white" utility in pse, but was disheartened to discover that it doesn't seem to work with tiff files. Also, the "adjust smart fix" and "auto red eye" options are not available with tiff files either. Is there a way around this?

  • Black and White conversion

    Has anyone worked on finding greyscale conversion 'slider recipes' that give a similar look to various popular films. Would appreciate if you could share some of these.
    Cheers
    Kev.

    onOne offers a set of 85 Lightroom Presets, which includes 10 black and white presets you might find worthwhile. You can download them for free at the bottom of the page in the following link:
    http://www.ononesoftware.com/downloads/
    If you have PhotoShop, you might also find their plug-in called PhotoTools helpful. It has three times as many presets (in the professional version), but does not work in Elements. Check out the video tutorials about using the library, using presets, and using the stack, along with the four real-world examples of how to apply the presets at the bottom of the list at this link:
    http://www.ononesoftware.com/tutorials/tutorials_phototools.php
    I currently have Elements6, and onOne's Plug-in Suite4. The fact that PhotoTools is not compatible with PE6 makes me want PhotoShop even more. Fact is, the only reason I haven't upgraded to that is I am waiting for CS Next before doing so.
    There are also presets made available by other users... some free, some not, at the following link:

  • Multiple Black and white conversion from raw or jpgs

    Hi All
    Any help would be appreciated.
    I have 300 wedding images taken on raw and jpg. I now want to convert them all to black and white. Any way I can do this without doing it one at a time (whether using raw or jpg files)?
    Hope someone has the answer or else I need to fork out £500 for CS4!!
    Clive

    Hi
    Thanks for reply. I am able to open and convert from raw ok, what I don’t know if I can do is process multiple files that have been changed, i.e. to black and white?
    I don’t think PE8 will actually do this.

  • Very Disapointed in Black and White conversion in CS4

    In CS3 it was great to have the hue/sat sliders right there and to be able to watch the image as I changed it.
    The CS4 BW window is a MAJOR disappointment.
    Now we have to click the color box and click again and again and keep clicking if we want to make minor changes.
    No refinement here.
    The way it was in CS3 you could slide left and right and watch the image change while you were sliding.
    No need to add a hue and sat layer afterwards.
    Can't believe they took this away.
    HUGE disappointment in Adobe for having done this to us.

  • How to convert only part of a picture to black and white?

    Hello.  I just received PSE 8.  I want to convert a photo of my daughter to b&w but I want to leave her eyes blue.   Anyone know how I can do this?  Thanks so much.

    1. Find the smart brush tool (the brush with the gears on it)
    2. Select a black and white conversion style in the options bar
    3. Turn on Inverse
    4. Drag over the eyes (they will stay blue and the rest of the photo will become b&w). If you turn Inverse off, the eyes will become b&w and the rest of the photo will stay in color

  • Raw Black and White (CR2 Cannon) process in color

    I'm shooting black and white in raw/cr2 mode, and when I process them through Bridge / CS2, etc., they always come up color, not b&w. The same occurs with Picasa and other raw processing packages. Any ideas how to keep them B&W, rather than converting to it after processing?
    thx!!

    By its very nature RAW images are color because color is captured by the
    sensor and raw is simply the raw data captured by the sensor. If you want
    black and white from the camera then you would have to shoot JPG or TIFF if
    your camera offers TIFF. Now the black and white marker should be included
    in the RAW file so if your use the software that came with your camera then
    it is very likely that software would see that marker indicating that you
    had black and white turned on and simply convert the color RAW to black and
    white and show you that. You might think that you are getting a black and
    white RAW file but you aren't it is just the camera makers software seeing a
    simple flag and then doing the black and white conversion. Since these flags
    are generally proprietary Adobe doesn't read them.
    In the end you are better off doing the conversion to black and white
    yourself. There are many ways of doing it even in Adobe Camera RAW and you
    will always get better results.

  • After turning an image black and white, how can I color in a certain area?

    After turning an image black and white, how can I color in a certain area?

    How did you change it? Did you make your B&W on a separate layer? If so, just erase the part of the layer you don't want, or add a layer mask and paint with black over the parts you want to hide.
    If not, then you can copy/paste the original photo (you will need to press ctrl+A/cmd+A to select all before you can copy) into the new image. From there it depends on the relative proportions of B&W. Arrange the two layers so the one with the most area that you want to keep is on top, and either mask out the rest or just erase it away.
    For future reference, an easier way to do this when starting from scratch is to use the smart brush. Choose a black and white conversion style, turn on the inverse checkbox and paint over the part you want in color. The rest of the photo turns black and white, leaving what you paint over in the original colors.

  • Black and White from model

    Hello
    Do you know if it is possible with Photoshop CS6 to generate a black and white from a model (not a preset)
    I work up a  photo color that I am satisfied with the result, I would like to apply the curve   of gray image (which is not a simple conversion tool with nb) or histogram to another image or a series images
    an idea how?
    thank you

    Okey, my first guess is that you want color correction what you made for one image apply to other. If you want it to apply to series of image then best solution, for my opinion, is to use Actions and Batch. First open Actions panel, from it's menu choose "Start Recording", do all your color correction (just correction without using selections and masks). After you done everything in Action panel's menu choose "Stop Recording". Now you can apply that recorded correction to other image or with batch to bunch of them.
    Or maybe you need something like that http://www.webdesign.org/photoshop/photoshop-basics/using-match-color-to-get-uniformity-in -color-tones.9596.html

  • How do I print a booklet with a colour cover but with black and white inside pages?

    Hi there,
    I need to print a large amount of booklets, which have a colour cover but are grayscale on the inside. However, I am having trouble setting up my document to successfully do this and I am unsure if it is something I can change in InDesign or if it is something I should figure out with my printer driver?
    We used Page Plus for these booklets in the past and were able to do this with the same printer, so that makes me think there might be setting I could change in InDesign to achieve the same result.
    It integral that the printer knows that the inside pages of the booklet are black and white, as we get charged per copy for colour printing and it is vastly increasing our printing costs.
    My coworker believed that exporting the file as a PDF with the options: Colour Conversions (convert to destination - Pressure Numbers), Destination (sRGB IEC61966-2.1), and Profile Inclusion Policy (Don't Include Profiles) is making a difference. However, I don't believe is is the case.
    If anyone had another suggestion that I could try, that'd be great!!

    @Eugene – do you have details for "Export as Grayscale"?
    I tried with the following details:
    Target-Profile: Dot Gain 15%
    Convert to Target Profile
    Include Target Profile
    If I do it this way I get:
    Target Profile not included
    Wrong numbers for my colors
    (I tested with a self-made color wedge on the page for the percentages of Black shown below)
    Seen in Acrobat Pro 10 with proof simulation "Dot Gain 15%":
    100 % Black => 100 %
    80 % Black => 82 %
    60 % Black => 63 %
    40 % Black => 43 %
    20 % Black => 22 %
    I could convert to "Dot Gain 15%" in Acrobat Pro's Preflight Panel, but this would show the same wrong percentages (just tested).
    What I can do, however, is printing to PostScript with color separations, only color channel Black.
    That would work, if I chose a Distiller setting, that will not change the color, to convert my separated PostScript file to PDF.
    Seen in Acrobat Pro 10* with proof simulation "Dot Gain 15%" or any of the other available gray scale profiles.
    (Acrobat Pro 11 might get this wrong due to a bug)
    100 % Black => 100 %
    80 % Black => 80 %
    60 % Black => 60 %
    40 % Black => 40 %
    20 % Black => 20 %
    This separated PDF (channel Black only) can now be converted with a self-made correction* in Acrobat Pro's Preflight Panel to a gray scale PDF/X-1a.
    If done right * the color values stay as defined in inDesign.
    Output in my case:
    PDF/X-1a
    OI: GrayScale profile Black ink of ISO Coated v2 300%
    Tested with:
    InDesign CC 2014.2
    Distiller X
    Acrobat Pro X
    Mac OSX 10.7.5
    Uwe
    * There are several, convoluted steps necessary to get this (hope, I can remember them all):
    Not optional:
    Have a grayscale profile representing the channel Black of your intended output CMYK or generate one!
    In my case the base CMYK profile was: ISO Coated v2 300%.
    And I got a "Black Ink of ISO Coated v2 300%" profile for Grayscale conversions by generating this with my PhotoShop app.
    Maybe optional, but helpful:
    Change the color settings of Acrobat Pro X to use the color settings file you generated in PhotoShop where:
    Grayscale is defined as the black channel of ISO Coated v2 300%: "Black Ink of ISO Coated v2 300%"
    Mandatory, but somehow tricky:
    Then on to the Preflight Panel of Acrobat Pro to generate a custom preflight profile.
    None of the ordinary ones will fit exactly (at least in my Acrobat Pro X).
    1. Make a duplicate of an already stored Preflight profile that converts color to Gray. Name it appropriately.
    2. Include a single correction for converting to Gray Scale (at this time, or if you do something like that the first time, it's not possible to change or duplicate that single correction)
    3. Save your new profile. Close the profile.
    4. Open the profile again.
    5. Now, suddenly it's possible to duplicate that single correction (converting to Gray Scale).
    Do some changes, appropriate correction options, eg. adding "Black Ink of ISO Coated v2 300%" as OI to the PDFs you will convert.
    4. Use that duplicate single correction in your new Preflight profile.
    5. Save your custom preflight profile.

  • How can I convert a pages color document to a PDF Black and White doc.

    How can I convert a pages color document to a PDF Black and White doc.  Or, covert the color to B&W in a new doc?

    > How can I convert a pages color document to a PDF Black and White doc.  Or, covert the color to B&W in a new doc?
    The general idea is that you colour correct photographs once, archive, and convert with or without colour changes. The archived photograph is unchanged - or we would be colour correcting the same photographs again and again and again.
    If you have a photograph with a corrected exposure, you can open the photograph in the Apple ColorSync Utility, apply a colour space conversion to a grayscale appearance using the preinstalled ICC profile, save the photograph under another name, and place that in your pagination.
    If you have a paginated document with corrected exposures, and any such non-scalable bitmap or scalable spline graphics as you have chosen to add, you can render the pagination as a whole to PDF through the same ICC profile, carrying out the same colour space conversion on any and all objects.
    Caveat: If you intend the pagination for certain processes, in particular offset lithography, then you are probably  expected not to render the type to grayscale, but rather to render it to single ink solid black. No software can determine what printing process you intend, you have to understand a bit about printing, and how to set up general colour space conversions in software. Ask your prepress provider, and if the answer is not prompt and proficient, pick another provider.

  • Setting Black and White as the default when printing to a Canon Image Class 4080i

    Hi,
    I've got two Canon Image Class 4080i's that we are printing to at the school I work at.  I have installed the Canon UFRII V2.40 Printer Driver for Mac OS X and we are able to print to them fine through any macbook running 10.5 to 10.7.  My question is, how do I make the default printer setting be Black and White instead of color?  I know how to change it from Color to Black and White by navigating to the Quality menu through the Print screen but I have to do this every time I print.  Is there a way to make black and white the default?
    Thanks in advance,
    Cheryll

    You’re really going to take photos straight out of camera on a 5d3 and print them with a blindly applied B&W conversion from the printer?  I would highly discourage that, but if that’s what you want to do I’m sure it’s possible.  Sorry, I have no experience with that printer so I can’t help.
    Do you have a laptop?  My recommendation would be to use a photo processing software like Lightroom (if you don’t have it LR5 is ridiculously cheap right now), play around before the event to get a B&W conversion that you like – even the preset ones are going to be better than whatever conversion the printer does -  and then print from LR.  It’d hardly take any extra time, and you could get a brief review of the conversions on a laptop screen before printing. 

  • Setting up Colour and Black and White in one document

    I hope this is a stupid question. I am creating the school year book for the first time. It is 80 pages with a mixture of black and white pages and colour pages.
    Do I have to set Indesign up any special way so that when it goes to the printers it will know this.
    Can I have black and white masters and colour masters in the one document?
    Do I need to gray scale all my (black and white images) in Photoshop first?
    Do I need to do anything to the text to make it print in Black and white if I am using a black coloured font???
    Thank you for your help.............it is greatly appreciated

    >Do I have to set Indesign up any special way so that when it goes to the printers it will know this.
    Maybe. How is it going to be printed? Have you talked to the printer about it?
    >Can I have black and white masters and colour masters in the one document?
    In a sense, yes. ALL pages in ID are color pages, but you can certainly set up masters where the only color used is Black.
    >Do I need to gray scale all my (black and white images) in Photoshop first?
    InDesign CS6 introduced export to grayscale PDFs, but that turns everything in the PDF to grayscale so you would need to export your color pages separately from the grayscale pages, then recombine in Acrobat pro, or send to the printer in separate files. You also need to set your Appearance of Black settings (in the prefs) to Output All Blacks as Rich Blacks if you are going to export to grayscale or your black type will be screened to a dark gray. Personally, I'd do the conversions in Photoshop so you can see and control what is going to happen and avoid the export hassles.
    Grayscale content is output in the K channel of the InDesign file, and your screen preview may not be accurate unless you use overprint preview.
    >Do I need to do anything to the text to make it print in Black and white if I am using a black coloured font?
    Your text will print in whatever color is you choose for it. If you use the default [Black] swatch, it will output using only black ink.
