B&W image with color profile true B&W?

I have a 10mb B&W visual saved as RGB. It's 10mb which is too large.
I changed it to grayscale and it goes down to 3mb. Still too large.
How else do I change a B&W image with RGB color profile to plain B&W? Or is 3 mb the lowest I'm going to get?
OR how do I just make the file smaller? Changed Resolution from 300 to 72 but stayed at 3 mb.
Thank you.

File size is dominated by pixel data. If you save in a layered file format the file will contain pixels for many layers. Different files formats support different things and compression. 10MB and 3MB would be very large image if the file format is Jpeg. For Jpeg only supports 8 Bit color mode and does not support layers and transparency.
I downloaded your 9+ MB png file and found it hard to believe the file was that large when I opened in Photoshop. So I did a Save As and save it xxxxxx.png it size turned out to be 131KB

Need help with Color Profiles between Photoshop and iPhoto

Hey guys, I'm a photographer and have always used Photoshop in comination with iPhoto. I am having great difficulty lately with color profiles randomly changing within albums of pictures. I need all of my images to be in sRGB, but some somehow end up in Adobe RGB. It seems to happen at random. Apple seems to think it's an Adobe problem. Adobe isn't sure what to do. Anybody aware of any known issues between CS5 and iPhoto using OS 10.8.4 with regard to color profiles and how to fix them?

The article also says you need Scribus to then further process the SVG file.
@shaunamm You need to open the SVGin Illustrator, not place it. But I doubt that you will be able to get the effects in Illustrator.

Issue with color profile image processing

Their seems to an issue with the iPhone displaying an image which has a Color profile of: Generic HDR Profile. The image appears very dark and nearly unviewable. This has been frustrating to trouble shoot becasue the image will display correctly on the computer, but when it is viewed on the iPhone it looks completely different. When images have other color profiles such as sRGB the images will look the same on both platforms. When an image has a Generic HDR color profile it will not display correctly on the iPhone.
Anyone else come across this problem?

When PSE gets weird, the first thing to do is to reset the preferences. Go to the editor preferences>general, click this button and restart the editor:

A little problem with color profiles

I am trying LR and so far I love it, it has successfully replaced RSP for me, and also beat Bibble which I briefly considered but didn't like due to the weird UI.
However, I have a little problem with colours, which has never happened so far with other converters, and I am hoping you can help me to solve it.
My monitor is calibrated with the Spyder and the appropriate profile loaded in the video card.
When I work on a RAW image in LR, and then export a sRGB JPG, and then open it with a browser, or the Win viewer, I see it redder. If I open the image in Faststone, I see it almost sepia.
If I export a TIFF and open it in PS, I see it as in LR, but when I export a JPG from PS (this is my typical workflow), the resulting image has the same problem.
Considering that my entire workflow is in sRGB, can anybody coach me as to the correct settings I must use in order to obtain a final sRGB image with the same colors as in LR? I think that I must be doing something wrong, as the program behaves consistently with PS.
Thank you in advance for any help you will be able to provide.

Funny how it's only Windows users that have this 'problem'.
This is not a 'problem' at all. The only 'problem' here is that you've been used to using non-color-managed applications. Suddenly, Lightroom comes in as a mature, color-managed, program... and you're all going bonkers.
Mac users aren't going bonkers because we're used to using color-managed applications (Preview, Safari, etc. are all color-managed on a Mac).
Let me clarify for you that by 'color-managed', I mean that the software is *not only* reading the embedded profile in your image, but is *also* converting, on-the-fly, the RGB values of that image to a new set of RGB values that compensates for the native response of your monitor. Say, for example, your monitor only displays a narrow gamut of reds. Chances are, then, that LR or PS will intelligently compensate for this by saturating reds before sending to your monitor. This is how color management works. You can now imagine the disastrous effects that a bad/inaccurate monitor profile might have...
Your Windows applications, such as 'Viewer', use the Microsoft ICM 2.0 API. This *will* read the embedded profile in an image, but instead of converting to your monitor profile for output, will simply convert to sRGB. That's basically like half-a$$ color-management. Read more about it here:
http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/prork/prdn_img_vkev.ms px?mfr=true
Firefox & IE don't even use the ICM 2.9 API, making them entirely non-color-managed. Whatever the raw RGB values are in your image, these applications spit out at your monitor.
It's very important you understand these simple concepts before proceeding any further.
OK, ready?
The original monitor profile that came with my MacBook Pro (profiled by someone over at Apple generically for all MacBook Pro LCDs, I guess) really seems to have underestimated the gamut of my monitor. Hence, color-managed applications compensated for this be resaturating my images (especially in the oranges/reds) before outputting to monitor. Therefore, images looked really nice and saturated in color-managed applications; however, when I exported them to sRGB JPEGs and then uploaded to the web, they looked desaturated (in Firefox, NOT in Safari, since Safari is color managed). They even looked desaturated on other people's monitors (these 'other people' were your average Joes...).
I then profiled my monitor using an i1 colorimeter. A 3-D plot of my monitor profile now showed that it actually had a much larger gamut than what Apple had predicted in their profile (but this gamut was still much smaller than sRGB, or the gamut of my Dell LCD or Sony CRT, etc.). Therefore, now, LR and PS, using this new profile, showed images much less saturated. Now when I made my edits, and then exported to sRGB JPEGs, images looked slightly *more* saturated in non-color-managed applications and on other people's computers.
So, you see, your monitor profile affects how you make adjustments/edits in color-managed programs. If your hardware profiler profiled your monitor incorrectly (which I assume is the problem here), then you may be over-saturating certain colors within LR, skewing those RGB values so that a non-color-managed program, which will not re-correct these values as LR is doing, will display the image with too much, say, red.
Bad monitor profiling also explains why you see this problem only on certain images/colors... if it were a LR problem, you'd most likely see it on every export. The color variance is more than likely due to a bad monitor profile that is not accurately describing your monitor's native response... hence LR/PS are incorrectly adjusting your images before sending to the monitor.
And at this point, please don't resort to saying "but the colors in the web browser look 'right' and LR looks 'wrong'". This statement has no meaning, as what looks 'right' to you in your web browser might look horrible to someone else with a different monitor. The point of color-management is to minimize these differences. For example, I was very unhappy by how desaturated my images looked on the web compared to in PS before I calibrated my monitor. Now, images look slightly *more* saturated on the web than in LR/PS, which I'm OK with. *Should* they look the same? Heck no. Similar? Yes. Is it better if they do look the same after hardware profiling? Yes, if your main goal is web export, but, keep in mind, the only way they *would* look the same after PROPER hardware profiling would be if your monitor happened to have a very sRGB-like response (to explain this would take another few paragraphs... but you should be able to figure it out if you ponder a bit).
I hope this is making sense. Let me ask you a couple questions now:
1.) For your headshot image, IMG_8860, which colors look 'right' to you -- the colors in LR, or the colors upon export (i.e. the headshot on the left or the right in your link above)?
2.) How exactly did your profile your monitor? Was it in the dark? I had quite a bit of variance in my monitor profile depending on whether or not the Mac OS X dock was visible at the bottom of the screen -- the light from the dock leaked into the colorimeter which then led to profiles that generated yellow/green color casts.

Trouble with color profiles?

Since installing photoshop, I've had no problems. A few days ago, I accedentally hit some hot key which changed some color profile settings, but I can't figure out which ones. Now, when I save a jpg or gif, the colors are much brighter and more vibrant than my working colors. If I turn on the proof colors preview, I get the true image. However, I never had that set before and it doesn't stay set now. Anyone know what's going on? The proof colors are set to "Monitor Colors".
I attached a sample of the same image open in photoshop and the saved jpg image open in Preview. I'd appreciate any help you can give me!

This has been discussed ad nauseam here, and there are many existing threads on the subject. This type of thread can get very long in no time. I suggest you take a look at them.
In a nutshell, you need to calibrate and profile your monitor accurately, select a working color space, honor that tag (color space) in all files you open, and tag all your files with the color profile in which they were created. Then look at the image in a color managed application.
If you choose not to embed the color profile in a JPEG, meaning you end up with an untagged JPEG file, be prepared to see color differences between the appearance of the image in some applications, most especially if you have a wide-gamut monitor. For instance, Photoshop and Firefox 3.0.8 (the latter with color management enabled, which is not by default) will correctly assume sRGB for all untagged images. On the other hand, all Apple applications, from the Finder through Preview, Safari, iPhoto and Aperture, just throw monitor profile at all untagged images. That will produce exactly the effect you show.
Similarly, if you leave an image created in, say ProPhoto RGB, untagged, it will look like it's on fire in Photoshop and Bridge, as well as in the Finder, etc.

Problem with color profile printing

I have an Epson R280 and an Epson NX415 scanner/printer combo. When I print from Photoshop to the R280 it's very easy, I make sure that in the printer settings, under Color Management, ICM and "Off (no color adjustment)" are selected. According to some tutorials I've seen online, this is the way to ensure that the printer driver will not perform any further color conversion, and that the working profile will be the one selected under "Printer profile" in the Photoshop native dialog. In that list I have a few color profiles available for the R280, which I assume were installed in the system when I installed the driver for the R280. With these profiles, as long as I select the Epson R290 R280 profile, it prints very close to what I see on the screen.
The problem is that replacing all six cartridges on the R280 is over $80, while replacing all four on the NX415 is about half, so I use this one for almost everything. The big problem I have with it is that the drivers didn't install any color profiles, so I cannot find the right profile to print to it. So far I've tried using the R280 profiles and some work better than others, but none of them gives me the right colors that I see on the photo inside Photoshop. One of them called "SPR280 290 Photo Qlty IJP" comes close, but it's not the same, I see that the hue is a little off, especially on yellowish areas.
So my question is, how do I get profiles that are meant for the NX415, for each type of paper? I don't want to keep wasting ink and paper doing print tests.
Thanks,
Sebastian

If it didn't install any profiles, it may just expect the data to be in one of the standard document profiles - e.g., sRGB. Some printer drivers work this way.
If you're unable to find an indication one way or another with a web search of what profile to use, I'd try sRGB and maybe Adobe RGB to see if they appear to match.
There are devices you can buy to allow you to profile your own printer with your paper, etc., though I have not used one.

Newbie needs help with color profiles

somewhat new to digital photography and send most of my stuff to local lab (Costco) when needing to print. I have a mac, with Leopard, and use Lightroom to export to jpgs and upload to the lab site.
Simple enough, but I noticed their site had the icc's available to download. My intent is for lightroom to rendor and export the photos the way their lab will print them.
Why bother to really develop the picture to my liking if it is just going to print differently.
I dont use PS and not sure how I can, if at all, utilize the color profiles the lab provides in LR.
Sorry if I am not making sense, any and all help is appreciated from you really smart people:)
Thanks

See http://lagemaat.blogspot.com/2007/12/mildly-lightroom-workflow-for-printing.html
You can now also use the
LR/mogrify plugin to convert to any profile you want. Much quicker than the photoshop route.
Note that there is no reason to do this if you do not hardware calibrate your monitor. Otherwise sending them sRGB is more than good enough. On a Mac, make absolutely sure that you at least software calibrate your monitor. See http://www.computer-darkroom.com/colorsync-display/colorsync_1.htm
Doing this will already improve it quite a bit, but there is no substitute for hardware calibration.

Fill image with color

Hello, please help me to find the answer.I have an image (doesn't matter
what format it is. I can use most suitable, even export from Photoshop can be used).
I would like to fill it with color. Is it possible to do it using JavaFX?
Here is an example. PNG image (please, see the link ) with transparent alpha and black color. Is it
possible to replace black color programmatically?
As I've read there is some plugin for Photoshop that allows to export work in JavaFX readable format, is it possible to realize my idea with the help of this Photoshop plugin?

I've tried it with
1. bind instruction:
    paint: Color.LIGHTBLUE
    width: bind image.width
    height: bind image.height2. without bind:
    paint: Color.LIGHTBLUE
    width: image.width
    height: image.height3. without bind and with additional pixels:
    paint: Color.LIGHTBLUE
    width: image.width+100
    height: image.height+100
+100 is random number. I should print image.width and image.height before declaring effect blend.
File is situated in the same package with fx file. I think it doesn't take too much time to load img.
I know dimensions of image, but I would like to work with abstract image, it's not good to hardcode dimensions or ask user about image dimensions. User is not a professional and he doesn't have to know such dull things :)

Export Simplified Image, with color markers

Hi,
I have a few graphs that i'd like in a report, they need to look neat and will get resized along the way. So i need to export them as vector based graphics (.eps or .emf), i have been using Export Simplified Image (Object Shortcut Menu -> Data Operations ->Export Simplified Image). For most plots this has worked fine.
Problem comes when i make plot with just markers no lines, when i do the export the marker points are always black. I would like to show the differences between some data sets using colour not just marker shape. When i do the same plot but with lines and markers, then both the lines and markers come out in color. Exporting to .eps and and .emf has identical results.
An example is attached, with the two plots (with lines and without). I am using LabView 8.0 on WinXP could it be a version thing? Anyone willing to test on other versions?
Thanks
Tim (LabRat1)

Hi Topher,
How are you doing this? Are you going to right-click>>Export Simplified Image. I have done this with the code attached on the forum above and this works fine for me using 8.6.1f1. You could try installing the patch for 8.6.1 if you haven't already to ensure we are on the same version. This is available at http://joule.ni.com/nidu/cds/view/p/lang/en/id/1276 although it should not fix anything to do with this. Does this also not work by using the property node as described in the KB at http://digital.ni.com/public.nsf/allkb/5AE4ADCBB65A6D8F86256FBF007A1AC1?OpenDocument

IBook Screen Has fuzzy white image with colored lines on it?

Hi, I have an iBook G4 1.33 Ghz. I was using it the other day, then all of a sudden the image faded away and the screen turned white with little random blotches of colored lines all over it. It does this every time I start it up now. I dont think it is the graphics chip issue, because when I hook it to an external monitor or TV, the computer runs fine and does not crash. I get a perfect image on the external monitor, just no correct image on the iBooks display itself. I've tryed resetting PRAM and PMU to no luck.
Any Ideas?
thanks.

HI Allen,
*"little random blotches of colored lines all over it. It does this every time I start it up now."*
According to this thread, it could be the logic board. http://macosx.com/tech-support/mac/ibook-g4-screen-turns-from-black-to-white-slo wly-on-starup/18233.html But it can't hurt to try maintenance anyway because clearly something is wrong.
Check the boot disk for errors. Restart your Mac while holding down the C key, pressing the power button and inserting your install disk all at the same time. An Installer window will open, but do not proceed with any installations. Instead, from the Menu Bar, select Utilities > Disk Utility. In the Disk Utility window click First Aid, and then click Verify. If Disk Utility reports errors, click Repair. When Disk Utility is finished, from the Menu Bar, select Utilities/Startup Disk. Select MacintoshHD 10.x.x and click Restart.
To check your hard disk’s S.M.A.R.T. status: Open Disk Utility, in the Utilities folder in the Applications folder.Select the disk in the list at the left, and look at the bottom of the window for a field named “S.M.A.R.T. Status.”
Check available disk space. Right or control click the MacintoshHD icon on your Desktop, then click: Get Info. In the Get Info window, click the discovery triangle so it's facing down. You will see; Capacity and Available Make sure you have 10% available disk space, 15% is better. Insufficient available space, can cause performance issues, system corruption, and possible loss of data.

Is it possible to fill images with color in Keynote???

I have a map of europe I made in Photoshop showing different empires before World War I. Is it possible to apply a colorize effect to my layers when I bring them into Keynote.
I would prefer to decide what colors the layers should be in Keynote rather than in Photoshop.
Also can Keynote import a multi-layered photoshop file?
Thanks very much in advance.

You could also try using a map that has the countries included as vectors. Here's a PowerPoint file I found.
http://www.presentationmagazine.com/world-maps-vector-editable-507.htm
Then, you can set the fill just as you're thinking about. You could even make the fill an image this way.

ACD 23 and Radeon 9800 Pro - strange behaviour with color profiles

Hello,
I have just purchased a 23" Cinema Display. The first one I got in the store exhibited ghosting effects that ceased to exist after a few hours (self healing effect?) and I also noticed after a while using it, that the left side and especially the lower corner were darker than the rest.
So I took it back yesterday and got a new one which is close to perfect. Neither of them had any dead pixels! I am very pleased with it and knocking on wood, hope that it stays that way;-)
My hardware: The display is hooked up to a G4 MDD dual 1,25 with a Radeon 7000 pci card and a Radeon 9800 Pro AGP card. The latter card was put in for the Radeon 9000 pro that came with the computer. So far I have been running a dual display setup with a 21 and a 17 inch CRT.
Now comes my problem:
I calibrated the cinema display hooked up to the 9800 Pro with the eye-one and the eye-one match software. The profile I got was not a smooth curve, but a zigzag curve. Of course that is by no means usable for anything.
By numerous trial and error attempts, I did find out the following:
- If I calibrate with the eye-one, I can have only one monitor hooked up to the computer, otherwise I will always get zigzag curves in the profile.
- If I look at numerous testcharts(greyscale, etc.) with the newly created profile, all looks very good and in specs. As soon as I hook up the second monitor again, something changes on the cinema display, even though the profile has not changed. My testcharts look a bit contrastier and on the greyscale the two darkest and lightest fields do not seperate anymore.
Rebooting does not help either. As soon as I unplug the second monitor, everything looks perfect again.
I know that this is an unusual issue but I hope that someone here has a clue to where the problem could be. I have tested so much and do not find a solution.
I will call the apple hepldesk, but I already know what they will say:"The display is working as designed. Your issue has to do with the graphics card and that is a third party product. You have to call ATI for support".
So, maybe I can get some help here.
Cheers
Peter

Hi Bryanus,
Did you have an ADC port on your old card? Do you still have your old card? If this is the case, you can verify that the new card is implicated by re-installing your old card and seeing whether the problem repeats itself.
If you only have DVI on your old card, you would have to borrow an adaptor, but then you are relying on the adaptor to function properly.
If the problem doesn't repeat itself with your old card being used, then the new card is the culprit, in which case I'd ask to have it replaced, or get a refund.
If the problem does repeat itself with the old card, then you might want to consider other possible contributing factors such as the physical state of the monitor connection (dirty or tarnished contacts, bent pins etc.).
If the problem repeats itself with a new (replacement) card, you could add AGP slot issues to the above paragraph.
"Sleep" in an Apple Mac often generates issues with third party hardware, so your primary consideration that it is probably the card is (to me anyway) still the most likely.
All the best with the diagnosis!
Cheers!

Photoshop diplays all images with desaturated colors (Images look fine when opened in other apps)

All of a sudden, when I open any image in Photoshop, the colors appear to be desaturated...In Photoshop only. When I open that same image in Window Picture Viewer, or Quicktimer, or even if I drag the image into a brower window, the colors appear fine. But in Photoshop, something is clearly wrong. Now, I can make color adjustments to the image, but when I save and reopen reopen it in another application, I can see that color changes have been made, but they still don't match what Photoshop is displaying.
The images are RGB image...I've checked the color space setings in Photoshop, and they are the default (Edit > Color Settings: North American General Purpose 2 / RGB: sRGB IEC61966-2.1 / CMYK: US Web Coated (SWOP) V2, etc, etc). I also made sure View > Proof Setup was set to: Working CMYK. I even reset Photoshop to it's default settings (by holding down CTRL-ALT-SHIFT on launching Photoshop)...But the images still appear desaturated when I open them in Photoshop...So, I don't understand how this is still a Photoshop problem...But then again, they look fine when I use any other application on my computer to open them, so it's clearly not an issue with my monitor.
The frustrating thing is, I haven't made any changes to Photoshop OR my monitor (that I know about)...Photoshop has worked perfectly for me for years, and now there's this SNAFU that I just can not figure out.
Any suggestions?
I've included a screenshot below to show the disparity between an image opened in Photoshop (on left) and Windows Picture Viewer (on right):
Photoshop image on left, with desaturated colors...Same image in Windows Picture Viewer on right, where colors appear normal.
Any and all help is much appreciated : )

It's difficult to provide help without knowing your level of color-management expertise, but I think you've helped us some with that in post number 2.
Color management is basically this: Images and devices have certain color characteristics, and these are described by color profiles, sometimes also called color spaces.
1. You should not need to use the Proof Setup at all to view your images on your monitor. When things are set up properly Photoshop shows you accurate color without your choosing View - Proof Colors.
2. A color-managed application like Photoshop will try to show you accurate color on your display by interpreting both the image profile and your monitor profile and transforming the colors accordingly. BY DEFINITION this will look different than other applications which don't do color-management as these just pump the image RGB values directly out to the display.
Thus:
If your monitor profile indicates your monitor has a wide gamut, images with embedded profiles may appear less saturated inside Photoshop than from non-color-managed apps.
If you view images that have an embedded wide gamut profile (such as Adobe RGB 1998 or ProPhoto RGB), Photoshop and other color-managed applications will interpret that profile and the colors will likely appear more saturated in Photoshop than in a non-color-managed application.
It sounds as though the first case applies in your case here.
You can check to see what monitor profile is associated with your monitor through OS settings. I'm thinking, based on the caption buttons in your screen grab, that you've got Windows XP, but rather than go further with that assumption, I'll ask you to verify it first.

Which color profile to use, if any, for web?

Hi,
For years, I've been accustomed to saving JPGs for web use by including the sRGB color profile.
However, I now realize that IE either discards color profiles, or forces a new one on them (took me this long to notice because while I always proof-check my code through IE, I never paid close attention to image colors 'til now). Meanwhile, Firefox actually uses the ones the JPGs were saved with, so I see the exact same thing in Photoshop as I do in Firefox.
Anyway, as I was saying, I just noticed the colors are very different in IE. In fact, trying to match a hexadecimal color value with a JPG is pretty much impossible as long as both IE and FF interpret JPG colors differently.
As a test, I tried saving a JPG with no color profile included. Interestingly, it showed up near identically in both FF and IE.
Which begs the following question :
Why the hell have I been using color profiles all this time? :-(
Another observation I made is that the Adobe RGB color profile more closely resembles the No Color Profile state than sRGB does (sRGB is a lot less saturated color-wise).
So what is it I need to do now?
1. Go over the entire website and re-save all images with no color profiles.
2. Go over the entire website and re-save all images with Adobe RGB color profile.
The goal here is that I want my hexadecimal color values to match what's on the JPG (for example, when a gradient ends and goes to a flat color state, I'd like to be able to fill that region with a hexadecimal color value instead of using more images needlessly... but for this to be a seemless transition, everyone needs to agree and match).
Thanks.

I've been doing something completely different.
To the extent that a color needs to match or be like a color that is a background on my website (which is the usual issue I run into with color differences), I make a .PNG or .GIF file and use transparency. That way I don't get the problems associated with color profiles and web safe colors.

Color Profile Question

I recently purchased a new PC and have been working from it for about a month or so without any issues. My client sent me an email saying that her images were appearing muted on her computer screen prior to printing them off of a few common photo labs. I looked into it and tried it myself and it was indeed correct. All of the images edited on my new PC were muted...my first instinct was that it was the color profile. I converted the image to sRGB and it fixed the problem. Now comes the problem....my photos are saving under the wrong color profile. How do I prevent this from happening so that all my images are automatically saved the my preference of color profile. I hope this makes sense because my mind is spinning from trying to figure this out! Thanks in advance!

Thanks for taking the time to help, I looked at my Lightroom color settings since that's how I import my pics and it was set on Adobe Pro I believe... I changed it to sRGB.

Thanks for the info : I'll start with the 4th question because it's the less known factor with Elements
If you shoot raw, the settings of your camera (Adobe RGB) will be ignored. This setting works only with the out of camera jpegs. A 'raw' file has no color profile, so PSE needs to know which profile you want for the conversion. You won't find any menu or dialog entries in ACR for that purpose. So, to convert the file when you 'Open' in the editor, PSE looks at the settings in your editor (my question #2, Menu Edit/Color settings...
If you have chosen option 1, 'Always optimize for computer screens', PSE will convert the raw file to sRGB profile.
If you have chosen 'Always optimize for printing', PSE will convert to aRGB...
If you want to take advantage of the slightly wider color space of Adobe RGB because your home printer can use it, select the second option, but if you have to send the picture in sRGB, do not forget to convert before sending. Menu /image/convert color profile.
If you don't want to bother, use sRGB with the option 1. You won't risk forgetting to convert the client version.
Never use 'No color management' in the menu /edit/color settings
If you first convert to sRGB with option 1, you won't get any advantage to convert to aRGB afterwards
