Black and white to rgb

I have some black and white photos that I scanned that iphoto will not recognize because I believe they are black and white.
Is there any way to convert them to the rgb so iphoto will recognize them?
Thanks
I tried opening in preview and saving as rgb but that option is not there.
I cant find a save as rgb option anywhere.

Yes. I've created a couple of Automator workflow applications and Applescripts that can convert them to sRGB. The are Convert to JPG and Embed sRGB profile and Embed sRGB Profile 2. They can be downloaded from Toad's Cellar.
NOTE: You will have to do the conversion of the photos outside of iPhoto and import the converted photos as new photos.
OT
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier versions) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
NOTE: this is not the same as routinely backing up your entire iPhoto library folder to protect your photos. It only protects the loss of your organizational efforts that the database file contains.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. There are versions that are compatible with iPhoto 5, 6, 7 and 8 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
NOTE: The new rebuild option in iPhoto 09 (v. 8.0.2), Rebuild the iPhoto Library Database from automatic backup" makes this tip obsolete.

A black and white photo RGB or grayscale whats the best?

a black and white photo scan it as RGB or grayscale whats the best?

grayscale image would have smaller image size. And in Photoshop Elements you can always convert grayscale images to RGB.
Thus I would advice to scan the photograph in grayscale.

RGB Only Prints in Black and White

My Illustrator CS3 seems to have developed a strange problem. If I create a new RGB based document, a 'Web Document' or a 'Basic RGB Document' for example, and the print it, I only get a black and white print. If I create a CMYK based document it prints just fine. I have also tried creating a CMYK document and converting it to RGB and that prints fine too, but if I create an RGB document and convert to CMYK again I get a black and white print.
I have checked each of the colour profile and print dialog boxes to see if there are any differences bewteen a RGB sourced document and a CMYK sourced document but can't see anything obvious. This problem seems to have developed over the past couple of weeks as it used to print RGB without a problem.
Any help would be much appreciated as I've been going round in circles with this for hours. I should perhaps add that I'm no Illustrator expert!
Thanks.

I have found a solution to the problem by installing and using the PCL 6.0 driver instead of the PostScript driver (interestingly the PostScript driver is recommended by Xerox).
I am guessing that there must be a small error/discrepancy in the Xerox PostScript driver as it works fine in all other applications and indeed even in Illustrator with everything but RGB colour mode.
This also stacks up against the way the problem materialised as it seems that the error is only apparent in the latest driver, the previous driver (as shipped on CD with the printer) works correctly (it was updated by a Microsoft Update Patch originally).
It would be nice to raise this problem with Adobe and Xerox, but I wouldn't know where to start, so I'll stick with the PCL driver.

Help! Photoshop is in RGB mode but I can only paint in black and white

It seems like Photoshop is stuck in B&W. As soon as I open my document, it shows at the top that it is in RGB/8 mode. I've tried clicking Image>mode>RGB again just to be sure but it's already set to RGB. The document is one layer so there's no way another layer is affecting it. Does anyone have an idea what may be going on? I'd appreciate any help I can get!

If it says rgb/8 then it is in rgb 8 bit mode.
If your opening a file, it could be 1 or more of the channels are missing or a single channel is selected. Take a look at the channels panel and see if the RGB channels are there and RGB is selected.
{odds are this is not it as the name of the channel would replace RGB/8 ex. selecting the B channel would display Blue/8 instead of RGB/8}
Make sure your document is not in quickmask mode (hitting the q key switches between quickmask and normal mode)
{odds are this is not it as quickmask/8 would be displayed instead of rgb/8}
Make sure you don't have a mask selected
{Odds are this is not it as layer mask/8 would be displayed instead of RGB/8}
Take a look at your swatches and verify there are colors there and not shades of gray
{Odds are this is not true because RGB/8 is displayed}
And finally verify what adjustment layers are applied to the layers panel - Several adjustments are capable of changing the display to black and white while retaining the RGB/8 mode.
If none of this helps then post a screen shot of photoshop with the layers panel and the channels panel open. You can drag a panel away from the docked position to keep it open.

Black and white TV display.

I just purchased a Mini-DVI to Video converter for my macbook to make my TV my new monitor (screen accidents suck) and now I've got a Radio Shack GoldSeries S-Video cable running to my Samsung tv. The resolution is fine and everything works great except for the TV showing up in black and white. I've called AppleCare and they're not sure what's wrong. Anybody have some insight on this matter?

I can think of two possibilities:
1) There is a fault in the S-Video cable/adapter
2) Your TV is set to the wrong input setting
S-Video sends the luminence (brightness) and chromanence (colour) separately. Either the chromanence signal is not getting through (option 1 above) or the TV is not using it (option 2). In the UK, most TVs have a SCART connector which can accept composite video, S-Video or RGB video through the same socket - are you using this or something similar? The TV needs to be set to display the correct input connector (SCART) but also the correct signal (e.g., SCART S-Video, SCART RGB etc.). If you just select the default SCART option, it would probably be SCART-composite, which happens to use the same pin as the S-Video luminance signal so you get a black and white picture!
Hope this helps (and that I got the technical details right),
Simon
Edit: in short I think this is an S-Video/composite video issue - either the Mac is sending composite video and the TV is trying to display it as S-Video, or the Mac is sending S-Video and the TV is set to display composite.

Only opens in black and white...color is gone.

When I place a photo file into my new blank file in photoshop elements 5.0 (I know it's old) it will convert my picture to black and white. How do I get my photoshop to go back to opening my files as they are, in color??? PLEASE HELP!!!???

Next time you create a new blank file look at the color mode (towards the bottom of the new file window) and make sure that it's set to RGB, too. If the last thing you've copied in another program is text, PSE will start with that setting at grayscale and then everything you put into the file will turn black and white.

HP1515 only prints in black and white (sometimes!)

This is a weird one. Have 3 imacs in my school connected to a pc network with no problems. One imac when sent to one HP1515 will only print in black and white. However, if I print a test page, it prints in colour.
The same imac, if print sent to different HP 1515 prints in colour. Print command sent from different imac to said printer prints fine in colour. I cant work out what is going on here?!!!
Any help much appreciated

Colored Pictures Turning Black and White in Certain Files (PSE 9.0)

Hey guys, how's it going?
I'll try to keep this breif, but it may take a little while to explain. I've been getting a problem with PSE 9.0 where an image or layer that is in color suddenly turns black and white when I paste it into an open file. It's a lot easier to explain with pictures, so here you go.
Figure 1
Figure 2
(Before anything else is said, I would like to point out the reasoning behind relating a middle-finger, a hammer and sickle, and a pony from My Little Pony: Friendship is Magic into a single image; it's a parody project I'm working on. It's about 30 times weirder out of context, trust me.)
As you can see, the source imagery with "APPA JAK" on it (figure 1) is in full color, but when I pasted it onto the layer with the hammer and sickle, it turned black and white. This has become the same with a few other images I have found, but I couldn't find any reliable way to recreate the problem. The problem is also the same weather I find the pictures from the internet, copy those to my clipboard, and paste them or simply paste them from my computer.
If you need any more information (dxdiag, settings, etc. etc.) feel free to ask, and thanks in advance for helping me!

Just a guess because I don't have the original images to play with, but the hammer and sickle is a grayscale image so images posted into it become grayscale.
Use Image / Mode / RGB Color to change the target image to color before pasting anything into it.
Alternatively, use File / New to create a new image that is full color and paste everything into it.

Trouble printing black and white

Friends,
I'm trying to print black and white on an imac i7, snow leopard, hp premium plus all in one (309g) printer. The prints have a slight purple cast. It is highly noticeable when the prints are placed next to older black and whites printed with an HP 8450. I print out of Aperture normally, but I'm having the same problem printing from preview. I use hp paper and inks, and the hp printer profiles.
Any ideas?
Thanks!
Steve

I used all current profiles for the printer. However, I just tried something different:
I turned off colorsync and let the printer manage the colors. I got a MUCH BETTER
black and white rendition. Who woulda thunk it -- all this effort to manage colors,
and the printer does a better job than we do. Go figger.
Thanks for your help.
Steve
You have the right idea, at least in some respects. The trouble with Apple's color managements system and pretty much all graphics programs these days is that those who coded them haven't got a foggy idea about black and white nor even grayscale. For instance the color filter for "black and white" is not true black and white, it is RGB gray; in other words it is using three colors to produce gray (or black) and that is just not the same. RGB gray images are still 24-bit images whereas true grayscale is 8-bit and true black and white is 1-bit. True black and white images can be very high resolution yet be very small files because of the phenomenal compression that's possible. Only those of use who actually work(ed) with black and white film and black & white ink on presses truly understand black and white color. Which is unfortunate because RGB gray is so poor and the files are just HUGE!
I've encountered the same problem, and am trying to solve it also. Perhaps I can find a profile for true black and white. Or create one? For instance, as I mentioned above, Preview has a filter for black and white, (but only to save a pdf file) and if you then save the pdf file as a TIF via that black & white filter and then load the resulting image into a program that's actually capable of black and white, you will find that the file it created is actually RGB gray (24-bit) - it LOOKS gray but it's not. Whereas if you load a true black and white image into Preview (Preview unfortunately has no means of creating true black and white, nor even to convert back to color) then you will discover that now you have the option to save as 1-bit or 8-bit gray (1-bit being true black and white with no shades of gray and 8-bit being grayscale with 256 shades of gray i.e. 0 to 255).
So while PAHU writes...
Black and white printing of photos (aka grayscale printing) uses other colours,
not just black, to make grays. If you can see a purple cast, this could be a result
of the magenta not printing in the correct spot or being too prominent in the print.
...that is correct insofar as what printers/programs typically are doing with the given color profiles, but it is not correct. Grayscale should NOT use other colors; grayscale should use only black (which is also more economical). By turning off colorsync you likely enabled the printer's color management system to take over and print true grayscale (black ink only).
So I don't yet have a solution, but I do agree that you've touched on a glaring deficiency in Mac OS color management and probably a great many graphic programs today, and likely the same goes for many printers.

Lexmark C54x - True Black and White Printing

As shipped this 1200dpi color laser printer - C543dn works with Leopard over a network (yes!).
There is only one thing I wanted to do that was not obvious - how to force black and white even when printing originally color images, and make sure only the black toner is used. A lot of websites use color, of course, and you may not want to pay for that either in time or toner!! As you probably all know the quartz filter option has been removed in Leopard, so unlike "another OS" you don't have a simple printer-independent "print mode" setting to set to black and white.
After a lot of looking around for a manual which details the printer driver options (there isn't one - confirmed by Lexmark support) this is what I have puzzled out. BTW - There is an alternative approach that involves saving to pdf, and then using preview to resave the pdf with the quartz filter applied - but this is simpler if all you want to do is print.
Basic stuff - Printer Independent
You have to do the set up within "Print..." within in an application (like Firefox or Safari). When you select a Printer in the print dialog you can also use a Preset - it appears in the field under the printer name in the print dialog. To set up the profile the way we want it, first use the "downarrow" to the right of the printer name to access the extra print dialog options.
Now you need to get the Mac to turn everything color in the output to gray - you do this by finding the "Color Matching" option -- its in a pull-down list (half-way down the expanded dialog, in some applications that list starts with the app name (like "Mail"), sometimes its in a list that starts with "Copies and Pages" - each application chooses how this page looks, adding to the confusion). Inside that option, you select "ColorSync" radio button and find the "Generic Gray Profile" in the pulldown. This is the replacement for the quartz filter. But that doesn't mean the printer will only use Black toner... that would be too easy!
Printer Dependent bit - in this case Lexmark C543.
Now move to the "Printer Features" options (also in the list that has "Color Matching") and a new sub-list pulldown will appear - for the Lexmark it has "Quality 1" as the first option.
- In this sublist select "Quality 1" - set the Resolution field to 1200 dpi.
- Then select "Color" (still in the sublist) and set the Color Correction field to "Manual".
- Finally go to the "Manual Color" in the sublist and set all 3 of the RGB fields (Image, Text and Graphics) to "Display - True Black".
After doing all those settings, go to the Preset field pulldown (the one under the printer name at the top) and select Save As... Give it a nice name (Black and White, perhaps?). This way you can recall this preset and all the settings easily. For color you can just go back to the Standard preset.
Now you can print your monochrome masterpiece.
This way I definitely got black and white (grayscale output). Verifying that only black toner was used is not a slam-dunk but it looks like it was. Anyone who has better info on the printer driver and the correct settings (maybe this was overkill even?) please feel free to correct/enhance.
Hope this helps someone else.

I really like the printer. It is fast, and it was a breeze setting it up as a network printer. Built in duplex is also very cool.
The only drawback is that it uses a lot of toner, which gets expensive. So far I have gone through two black cartridges printing a little over 3000 pages. According to Lexmark, one cartridge is supposed to last 2500 pages, so that doesnt seem right. The pages I have been printing haven´t been THAT full.
But maybe this applies to other brands as well? This is the only color laser printer I have owned.
Anyone else with experience on this? I have been looking for toner refills, but so far no luck..

Why do some black-and-white photos disappear in Mac Preview and Safari?

I sent a PDF to a colleague recently only to discover that he uses Mac Preview to view PDFs and not Adobe Reader. The unfortunate part is that, although full-color photos all appeared, small black-and-whites were inconsistent: some appeared and others did not.
Moreover, the same problem turns up when using Safari, though Google Chrome displays the PDF perfectly.
One reference point is that a full version of the PDF appears just fine in Preview and Safari. It's when the original is reduced or optimized that some of the small black-and-white photos disappear. Of course all photos appear in Reader, even when they PDF is reduced or optimized.
I have examined the small photos and have been unable to find any consistent trait among those that appear and among those that do not. I have experimented with them: layered and flat, with and without alpha channels, with and without profiles, as RGB and grayscale, with byte order for IBM PC and Mac, as TIFFs and JPEGs — in other words in every variation I could think of. I have used both Acrobat Pro 8.3.1 and Acrobat XI. Nothing I have tried has varied the outcome.
The obvious solution is to avoid Mac Preview and Safari, but I am planning to distribute a complicated project to a large audience and can't control what viewers they use.
Does anyone know what the problem is?

As I reported and you confirm, the things I tried had no effect.
You point to the compression and image settings, but that leaves the question why some photos and not others showed up: presumably they were all subjected to the same compression and image settings.
There are a great many possible permutations of compression and image settings, and I'm on deadline. Is there perhpas a combination of compression and image settings you recommend?
Thanks!

Exporting to PDF in Grayscale - Black and White

We have recently been told that even though some of our reports have been created in black and white, they are not printing in grayscale. Since there is quite a difference in the price, we are trying to explore how we can export in grayscale. We are trying to avoid printing to PDF (which works when we change the adobe printer to black and white) because it takes a significantly longer time to create the number of PDF's we need to create. Here are the things we have tried:
- Making the default printer be a black and white only printer
- Changing the printing preferences to black and white (it seems our printers just revert back to color every time)
- Choosing the No Printer option in the page setup in CR.
If you have any other suggestions, it would be much appreciated! Also, if you have an idea why CR would continue to produce the report in RGB when the default printer is black and white, that would be helpful as well. Thanks in Advance!

After extensive research, we have found that Crystal Reports 2008 does not have a grayscale option for exporting reports - it will only export using RGB colors. The way we worked around this was export the reports to PDF, then used Adobe Acrobat to Batch Process all the reports using their "Convert to Grayscale" option. This seems to work just fine, but adds an extra step in our process.

Converting a PDF to pure black and white

I'm currently attempting to convert a PDF of any colorspace (RGB, CMYK, Grayscale etc) to black and white.
Currently I'm walking the PDF using Adobe PDFLibrary, separating the contained PDEElements and identifying them (Image, text, etc).
Does anyone have any advice on how to proceed from here? I figure the actual conversion operation will have to be written from scratch, as Adobe doesn't seem to support this. However, I'm having a hard time determining the colors of each object. I suppose I could rasterize everything and convert pixel by pixel, but I'd like to avoid that and preserve vector images and such if at all possible.
Thanks in advance for any help!

Yes, I'm aware that there is no monochrome colorspace. However, wouldn't it be possible (likely at a very low level) to fetch and modify the colors of elements manually?
I suspect the initial thing to do is convert images to the DeviceGray colorspace and work from there, so I have a uniform colorspace to work with when performing this operation.
I've noticed that if I pull the ImageData object out of a PDEImage, I get an array of bytes that appear to be pixel by pixel color data. Now, in doing this have I rasterized the image? What would happen to vector images if this array were to be modified?

Colored InDesign docs are wrongly being exported as black and white PDFS

Hello Sirs/Madams,
I am a new user to InDesign. I use InDesign CS4.
I have an .indd file that I created (simple, just text, nothing else). I went to Windows -> Swatches and changed the color of the page to dark blue (modifying the RGB). On screen, it looks EXACTLY like I want it.
But the problem is when I select File -> Export to PDF and I select ANY of the pdf profiles, it prints ONLY in black and white. I have messed around with many options, including using the File -> Print option (to Adobe Acrobat 8 Professional BTW) and it *still* creates a black and white pdf!!!
What am I doing wrong? Please can you help me?
All I want is that whatever colors I can see on the screen should be in the PDF, including the document/page area, which I set via the Swatches window. I apologize if its simple enough but please provide a measure of leeway considering I am taking baby steps here...
Thank you in advance.

The paper swatch is for preview on screen only and is intended to allow you to see how your document will print on colored paper. If you want to print a solid background you'll need to draw a frame and fill it with that color.

Why do my PRO-100 black and white prints have a color tint?

I am printing on the PIXMA Pro-100 printer and sometimes, for no apparent reason (?), my black and white prints will have a color tint (usually a "redish brown"), and then when printing again... same print, same settings... the same print will be fine, neutral with no tint at all.
Any ideas why?
Also (maybe related?) I don't understand why the Photo-Cyan and Magenta ink cartridges are being depleted when I am NOT printing color, but only Black and White. Am I missing something? When setting up for printing I always make sure the "Black and White Print" feature is selected in the settings dialog "Quick Setup". Doesn't this insure that only the black and grey inks are used as long as I am not "toning"? In other words... if ONLY the black and grey inks are used, isn't the print supposed to be a neutral black and white print? Again... am I missing something?
FYI:
I am printing on Canon Pro Luster and Plus Semi-Gloss papers.
Under "Options - Color Management" I have selected:
(color handling) Photoshop Elements Manages Colors
(image space) Adobe RGB (1998)
(printer profile) Canon PRO-100 <LU> 1/2 Photo Paper Pro Luster
(rendering intent) Perceptual
Solved!
Go to Solution.

It looks like you have the settings pretty close. But the fact is all printers use all their cartridges to print B&W.
Whoa, why?
Yes it is true and the reason is this. B&W consists of 256 shades of gray. From totaly black which is 0 to white which is 256.
If you have just one, two or three cartridges to make 256 different blacks and grays all the way to white, it simply isn't possibile.
The ony thing a printer can do is, amount of ink and how long. So it makes up for this by using all it's cartridges. However, in Canon it seems like the Pro-100 tints show up more than it should. There are dedicated B&W printers but they are designed differently to accomplish true B&W.
The tint will be different on different papers. You can experiment to find the paper that does best for you. Try a more gloss type paper and see if you like the B&W. You can try Red River papers, too. They will assist you in picking a good B&W paper.
You can also experiment with filters in PSE. Adding a little blue may help. Just give it a try.
But the bottom line is you are no doing anything wrong. It is just the charchter of the beast.
