Color mode and resolution questions

I'm going to work on a composition that will include made different photos. I'm not sure how it will be printed, CMYK or RGB. Without know for sure:
1. Should each individual photo file be set to RGB or CMYK?
2. How much of an affect will it have on the quality of an image if it is changed from RGB to CMYK or the other way around after it has been worked on?
3. I need to request photos from others to be included in this piece. Does the physical size of each photo matter as long as the photos are 150 or 200dpi? Should I request specific sizes or just photos with specific resolutions?
Thanks in advance!

2. effect
3. resolution

How to control Color Mode and Resolution for brochure creation?

Hello guys,
I am trying to find some settings within Pages, where I could set CMYK color mode and 300 dpi resolution for my pdf file.
I am creating brochure from scratch, using blank document, because non of brochure templates work for what I need. But I can't find any controls for color mode and resolution set up.
Is there any solution for this?

There has been a lot of discussion in the Pages forum about resolution and some on CMYK.
Much of the discussion has been incorrect.
For the colour handling there is the colour palette
The Apple Colour Palette is the user interface for colour managing vector objects created in Apple Pages such as rules and panels and for colour managing one class of vector objects not created in Apple Pages, namely typographic objects.
Imported objects maintain their colourant model and colour space, if there is one. If there is none, a colour space is assigned and the assigned colour space is saved out into the PDF, opposite e.g. Adobe Photoshop which will colour manage the object in the open editing session, but will then save out the object to disk without the assigned ICC profile if 'Colour Management: Off' is configured.
Therefore, if the imported object is data space CMYK and the colour space device CMYK, the system will assign the Generic CMYK Profile which is equivalent to ANSI CGATS TR001 colourimetry (US SWOP); if the imported object is data space RGB and the colour space is device RGB, the system will assign the Generic RGB Profile which is equivalent to sRGB colourimetry in OS X 10.5 and higher.
In general, always capture and then convert for correction in one of two data spaces with three channels, either ICC colour managed RGB or ICC CIELa*b D50. Then convert to CMYK1, CMYK2, CMYK3, CMYKn from the ICC colour space chosen for correction and archiving. This colour space should be large enough to hold any colours that the output colour spaces can hold.
The Apple ColorSync Utility has a gamut comparison dialogue which is 3D (point, press, and turn the 3D gamut comparison). Use this facility to pick an ICC colour space of reasonable size and shape for correction and conversion into final output. Don't pick sRGB as a quick look will show that it can't hold as input what ISO reference offset can hold as output for pure cyan, let alone hold what a big inkjet can hold in greens, blues, reds and yellows.
The ICC architecture lets the ICC profile for the printed output match out of gamut colours to in gamut colours using the Perceptual rendering intent, as intended in the original architecture from 1995. Adobe internally introduced an inhouse conversion for compatibility with PostScript and as default for PDF, Relative Colorimetric with Adobe Black Point Compension. Relative Colorimetric is in fact a proofing transform, without gamut mapping. Black Point Compensation is a simple linear scaling of the lightness to compensate for the fact that the shadows will be clipped in a Relative Colorimetric conversion.
The other problem is transparency, introduced in the QuickDraw Graphics Extension for Mac OS 7.5. Transparency is not supported in any version of Adobe PostScript (level 1, level 2 or level 3). Transparency is also not supported in any version of Adobe PDF prior to version 1.4 and higher. Therefore, unless the RIP Raster Image Processor is able to accept PDF 1.4 and higher, transparency has to be rendered / flattened which is done in the PDF/X-3 filter of the Apple ColorSync Utility.
The idea in the PDF/X-3 filter (for Adobe PDF 1.3) is that the everyday enduser, after placing ICC colour managed RGB or CIE La*b D50 objects, and after choosing an ICC colour space for objects created in Pages, chooses the ICC colour space for the output condition. The filter accepts both ICC profiles of type MNTR Monitor with data space RGB, ICC profiles of type PRTR Printer with data space RGB, and ICC profiles of type PRTR Printer with data sapce CMYK.
The colourant conversion (RGB to CMYK) and the gamut mapping (out of gamut colours in input colour spaces mapped to in gamut colours in output colour space) is then calculated as per the ICC profile for the output condition. An output condition is the combination of factors that affect how colour is formed: the colour lightness and colour tint of the paper, the colours of the colourants, and the tone value increase. Think of gamut mapping in a good ICC profile as Format 1 kerning in a TrueType font (where your font has state-based kerning for up to 8 glyphs simultaneously).
Below a link to a discussion of how to change the default PDF/X-3 filter the Apple ColorSync Utility. "Wegen diverser Fehler im Mac OS X empfiehlt es sich, wo immer möglich, die PDFs ohne Transparenzreduktion (also auf normalem Weg) über den Befehl Als PDF sichern zu erstellen und das Flattening der Druckerei zu überlassen," that is, pick the plain save as PDF path and leave the transparency flattening to the prepress technician.

Messed up color display and resolution because of mini-DVI to video adapter

Once I connected the mini-DVI to video adapter to the tv and got weird colors on my screen for a while but then it worked out, then after a while I disconnected the cable and turned my computer off. After that, everytime I turned my macbook on, the color is fine for two seconds and then it turns into a weird offset color, really bright colors, kinda sketchy and just a few colors, and a weird resolution and display obviously, but then I just connect my Mini-DVI to video adapter and disconnect it again (quickly) and the color returns to normal. How can I make the normal colors stay and not have to connect the mini-DVI to video adapater everytime I want to see the normal color display and resolution??
please help!

Open the Universal Access pane of System Preferences, click on Seeing, turn off the White on Black, VoiceOver, and Zoom options, and drag the Contrast slider all the way to the left. If the issue persists, create a new folder on the desktop, drag half of the items from the Library/Preferences/ folder of the item in the Finder's sidebar with the house icon into it, and narrow down the files until you've isolated the one responsible.

Possible to get the color space and resolution from the .eps file

Hi all,
We have using the InDesign CS3 5.0.4, windows, javascript. We need to get the color space and resolution of the graphics (.eps) file using scripting.
The properties of the image like (actualPpi and effectivePpi will return the value only for the .tiff. and .jpg etc) but it will not return the .eps file resolution values.
Kindly give me the suggesting for the decrepancies.
Regards,
Nagaraj

... open them programmatically in PhotoShop, read out resolution and color space ...
On opening them in Photoshop, it asks you "what resolution shall I use, and what color space shall I apply?"
A single EPS may contain any number of embedded bitmaps, with any horizontal and vertical resolution, and in any color space. You can use only a few of these with Illustrator -- and even only one at a time with Photoshop --, but other programs allow just about every possible combination.
Not to mention procedurally generated bitmaps, also possible with PostScript.

I am having a problem changing a color in a selected area. Using the Quick Selection tool I am able to select the area I wish to change. Using the Brush tool, color, color mode and click drag in my selected area, nothing happens, no color changes. I have viewed some videos and read numerous articles but haven't found the one to help me. Please point me in the best direction. Thank you Vincent TC

For the sake of clarity and to save people time, Todd is asking about the behaviour of the Patch tool when using it to repair the area next to the young lad's head. Todd gets a blurred dark tone pretty much regardless of the options he uses.
IMO that's what I would expect to happen because of the close proximity of the other image elements i.e. the lad's neck and the strong lines of his shirt. I would not choose to use the Patch tool in this situation. Content Aware Fill makes a better stab at it.

Colour mode and resolution

In Photoshop Elements is it possible to change the colour mode (ie from rgb to cmyk) and the resolution?

-It is possible to change resolution of a image using "Image Menu > Resize > ImageSize" dialog in PSE.
- PSE does not support CMYK color mode , so it is not possible to convert from RGB to CMYK in pse. You will need photoshop for that.

IPod Touch 4th Gen. iOS 5.1.1 - Sleep Mode and Other Questions

Hello,
I have an iPod Touch 4th generation with iOS 5.1.1
1) RE: Sleep Mode - I found this on another thread and it's regarding iOS 4.3.1.
Is the same still true for iOS 5.1.1?
If so, what is recommended for sleep mode - Airplane mode or Wi-Fi off - or is either one ok?
Wi-Fi is always ON with the 4th generation model running 4.3.1 when it is sleeping unless you either turn off the Wi-Fi or turn Airplane mode ON.
2) I only use my iPod Touch on my home Wi-Fi and do not use any cloud based syncing or iTunes Wi-Fi Sync. I do all my syncing manually from my MacBook Pro via USB to the iPod Touch. The way I do things is purchase what I need from my MacBook Pro via iTunes and then manually sync it to the iPod Touch. But there may be times, in the future, where I would want to purchase directly from the iPod Touch.
I recently updated my AppleID with my new email address via my MacBook Pro. But, I noticed that on my iPod Touch under "Settings" "Store" that it still shows my old AppleID. I have all Automatic Downloads set to OFF. How do I update the iPod Touch to reflect my new AppleID?
3) When I'm using Safari and I navigate to several websites, how do I easily get back to my home page (which is set to Yahoo!)?
Probably a dumb question but I can't seem to figure it out. I've set Yahoo! to my homepage but I would think there should be or is (and can't find it) a button/icon like on my MacBook Pro Safari to take me directly back to the homepage.
Thanks in advance for the help!

- Unless you use bluetooth, airplane mode and wifi off are the same as regards to battery drain. I like use airplane mode sinc that is directly under Settings.
- Go to Settngs>Store and sign out of existing account and sign in with the updated one
- I have no idea for the Safari question

Image size and resolution question.

Is an image at W 48.667 x H 32.444 inches at 72 res the same as an image that I could convert in photoshop to 300 res and then the with "Resample Image" clicked off would be W 11.68 x H 7.78 at 300 res for printing purposes? I'm asking this questions because after exporting 200 images from Lightroom 1.4, putting them into an wedding album I realized the images were not at 300 res but the first size listed above. I'm trying not to have to rebatch and have to put them back into the album. I sent the question to NAPP and got this back"
"If you do the math you'll see that the answer is "no."
48x72=3456 pixels; 32x72=2304 pixels
11.68x300=3504 pixels; 7.78x300=2334 pixels."
I did the math and it comes up to 5760 vs 5830. Pretty darn close. So would an image printed out with both settings print the about the same quality or am I missing something?
Thanks
Bob

Bob's question is a common one. And one of the first that most of us struggled to understand. Let's see if I can shed some light to help clarify the matter.
o The image starts out with a given number of pixels from the camera, scanner, or whatever was its source. The resolution only matters when it comes time to print the image.
72 dpi was once a common resolution for displaying on a computer monitor. Today 90 dpi is more common monitor resolution.
o Let's assume that the image is 3504 x 2336 pixels (which I got from his size @ 72 dpi).
o In "image size", if you do _not_ have 'resample image' checked, all you are doing is _rescaling the image. The image resolution is whatever you enter ...
For example, if you enter 360 dpi -- the native printing resolution of many Epson printers -- you get a print size of 9.733 x 6.489 inches
o Let's say you want to print this image at 360 dpi in portrait on 13 x 19 inch paper with a one inch border on the sides. That would make the short dimension of the image 11 inches and the long would work out to 16.5.
To do that you need to _resample_ the image to change the size. More pixels will be made. The resolution stays at 360 dpi. So check the 'resample image' box.
After resampling to get the print size and resolution you want, the pixel dimension goes to 5960 x 3960 (from 3504 x 2336). Those new pixels came at a price, but that is a matter for another thread and a lot of personal bias.
Hope that helped.
P.S. The answer to your question, Bob, is yes. With resample off in PhotoShop, your original images should have gone to 11.68 x 7.787 inches @300 dpi.
In looking at the rest of your original post, it seems that the export didn't work the way that you wanted. Do I read right that the images turned out to be 11.68 x 7.787 @ 72 dpi? Can't help with that as I don't do Lightroom.

Adjusting size and resolution question!

I'm trying to adjust size/resolution of a collage that I created so that it will look good when printed on a 20 X 30 canvas. How do I know the proper size and resolution to change it to?

We don't even know what program you are referring to, so it will be impossible to advise. In any case, usage questions are best asked in the product specific forums.

Canon pixma pro 9000II printing - color management and resolution settings

1) is the printer color management automatically turned off when I select the paper in the color management profile drop down? Or do I need to do something else as well?
2) a little bit of a newbie question, but I'm wondering what resolution to select (for presentation prints) - auto or 300 dpi. And again in the print dialogue box (under "quality and media"), whether to use high or standard. Wondering what to match with what, etc.
Thanks.

The answer to the first question appears to be yes. ColorSync is automatically enabled, and Canon Color Matching is automatically disabled.
Some tips on the second question would still be helpful, however. Again, I'm curious about matching Aperture "print resolution" settings (auto, 300, 72, or custom) to the print dialogue "print quality" settings (high, standard, etc.) under the "quality and media."

64 bit mode and some questions

Happy New Year all,
Just once I'd like to start up in 64 bit mode. I've tried to do it several times without success and I don't know what the problem is. Hardware, software?
I'm running two 10.6.2 systems, one on 1 SSD 3 drive Raid 0 array, one on another. Both internal and I used SoftRaid to set both up.
Each time I try, I get the gray screen with Apple logo and the spinning wheel. After a time I get the circle with a bar through it and have to use the power button to shut down. When I tried it last time on one array, the above happened and both arrays unmounted. I could only get my disks mounted by booting from a clone and both systems, the 32 and 64 bit, did not show in the Startup Disk Pref Pane. Both systems showed up when I pressed the Option key at start up but I couldn't start up from either.
I should have remembered to press the 3 and 2 keys to get access to those drives again but a PRAM reset got my 32 bit system back again. From there with a little research I saw mention of the 3 and 2 keys again, tried it on the 64 bit system and got it to boot in 32 bit.
Long story short though I don't know why I can't at least boot into 64 bit mode. Could it have something to do with the SSDs? Could it have something to do with SoftRaid? Why would both arrays dismount when only one should be affected?
Is it a common issue for many 64 bit compatible Macs to not be able to start up in 64 bit mode for any one of a variety of reasons? I should say that neither of my systems can start up that way.
Thanks, any insight is appreciated.

Talk to Mark and look for any notes on SoftRAID and 64-bit mode;
Try installing Mac OS only to one of your SSDs (break the array).
Just a nice small clean Apple ONLY OS.
"6" + "4" ought to get you into 64-bit kernal mode.
Any PCIe card/driver you have to be concerned with?
==================
SoftRAID 3.6.8 is compatible with Snow Leopard in 32 bit mode. You will be asked to replace the newer version of the SoftRAID driver that is bundled with Snow Leopard, with the 3.6.8 driver.
+A newer, *64 bit version of the SoftRAID driver* is included with Snow Leopard for users in 64 bit mode,+ which will allow you to keep existing volumes and access data from the 64 bit version of Snow Leopard. Currently, only the X-Serve boots into 64 bit mode by default. *SoftRAID 3.6.8 will not work in 64 bit mode.*
SoftRAID 4.0 is coming soon!
SoftRAID version 4 will be a full 64 bit Snow Leopard compatible version. We don't have a firm shipping date, but will try to have a "customer beta" in a few weeks for those who want to beta test SoftRAID 4.0.
The SoftRAID 4.0 official release will probably be in October. Upgrades will cost $69, except for 2009 purchasers, who will get it free.

Slide organizer and resolution questions

Slide organizer
-When I'm using the rehearsal mode, pressing the 'menu' button on the remote brings up front row, not the slide organizer. It doesn't matter if the 'allow expose, dashboard to use screen' option is checked or not. I'm wondering how this will actually behave when I'm actually presenting the slideshow. Will it bring up the slide organizer (which I want) or will it launch front row?
Resolution
-I'm still confused after reading the documentation on choosing a slideshow resolution. With options enabled allowing keynote to resize the slideshow, will that resize to the projector resolution? I don't know what resolution the projector is, so I'm worried everything won't display correctly. Any recommendations?

After years spent on PowerPoint this is something making me very confused too. I simply do not have idea why I should define "Resolution" ... when I do not know ... never ... what projector I will be using for my presentation.
Resolution of presentation never was the issue in PowerPoint

Boot Camp and Resolution question.

Hi, I'm currently typing from Windows on my Macbook Pro. It runs perfectly, except that the resolution is not widescreen. I already used the Apple Drivers CD that burned from boot camp, but the resolution still doesn't show up. A little help, please?

You installed the Apple-supplied drivers into XP, right? You should now be able to (in Windows) go to Control Panels and select Displays. When it comes up, select the Settings pane. You can then slide the screen resolution slider around until you get the MacBook Pro resolution. IF you can't select the full resolution, it is possible the drivers did not apply correctly.

Jdev11g R1: af:inputDate readonly mode and skinning question

Hi,
I have an af:inputDate with readonly mode activated. This hides the border of the component, reduces its width and hides the icon. I need to show a field where the user can't modify the date manually but can select the date with icon. Using css I can solve all except the icon. I can't show it with readonly mode activated (and I need readonly because the user cannot modify the date manually).
Any suggestion?
Thanks,
JVN

Frank,
I try with this code:
<script type="text/javascript">
function toReadOnlyMode (event) {
var comp = event.getSource();
var popup = comp.getPeer()._getPopup(event.getSource());
popup.show();
//popup.focus();
var glyph = component.getPeer()._getGlyph(event.getSource());
glyph.focus();
</script>
<af:inputDate id="testDate" clientComponent="true">
<af:clientListener method="toReadOnlyMode" type="focus"/>
</af:inputDate>Without luck. Please, could you help me?
Thanks,
JVN

Color space and compression question.

i have a client that i am doing an animation for, i am using their supplied rgb breakdown of their brand colors.
the client is concerned that their brand colours do not look the same when i send them quicktimes.
i have tried sending h264, x264 and prores, all look different.
is it actually possible to export a h264 and have the colours look identical to how they look in after effects?
is the a quicktime gamma shift thing?
are my project settings wrong?
id be interested to hear as to what your project settings are and what you export for "master" etc..
my after effects project settings are set up at srgbiec61966+2.1 at 16bit.
"match legacy after effects quicktime gamma adjustment" is ticked on.
"compensate for scene referred profiles" is ticked on.

so how do I go about getting the colours in my animation export to look identical to the brand colours?
colour spaces are not just for exotic footage. they are there to aid in eg. importing srgb photoshop files into srgb after effects to eliminate colour shifts.
