Export greyscale images

Even though I have have converted a color image to greyscale with great ease and control in Lightroom (that's why I chose LR over Aperture) I cant find a way to EXPORT the image as a greyscale image!
It is really annoying to have to run another programme to be able to make it a greyscale imagefile.
It should be a "Greyscale" choice in the exports menu for color space. Am I missing something or why is this not possible with Lightroom???
Please tell me how I can do it - and if it is not possible - get it into Lightroom 2, please!!!

Like printing services and such. Basically every commercial lab will have an issue with greyscale jpegs as the machines cannot read them. Photoshop of course reads them fine and if they go to professionals that do their own CMYK separations or other color management, there is no issue. On the other hand, if you would put them on the web, many web browsers (except safari and firefox 3 with color management turned on) usually get them wrong. I think it would be good to have the option to write greyscale files, but the default should be RGB jpegs even for black and white conversions. In jpeg, you should not get any size advantage, but you will certainly get it in tiff. If you go tiff, then all this about web and labs does not apply anyway.

Converting greyscale images to single spot colour

Hi there.
I’m trying to convert a greyscale image into a single spot colour image. The spot colour is PMS425C, a grey version but as I’m only printing 2 colours I need to convert these images into one spot colour.
Can somebody please assist?
Thanks

Did you see the monotone separated into cmyk? If so, you may not be making the PDF correctly and the spot is being converted. It can still have cmyk channels but they are empty and will not end up as plates. Check your output to PDF settings and make sure in the ink manager that spots are retained. Also, there is more than one way to view in output preview which can be confusing at first.
You should be exporting as PDF X/1a and if your settings are correct, when you view in output preview (separations) in Acrobat, you should see the spot as spot.
Try saving your monotone as .psd too many other formats will not support the monotone. If you view separations in ID, you will be able to see if your file actually supports spot colour.

Greyscale images

I am trying to create medical wall posters. I have converted the X-ray images to Greyscale using Photoshop, then inserted them into my Indesign poster. After exporting to pdf then printing, the images are no longer greyscale but are coming out in various tones of purple-blue grey. How can I keep my greyscale images "grey: without losing my coloured images? I have tried converting in Acrobat Pro, but this converts all my images to greyscale - I cannot select just the x-ray images. Thanks to anyone who can help.

I copied your screen. I have now also tried withthe following which seems to work quite well. Thanks for your help - I would never have got this sorted without it!!

Export greyscale

Hi
I'm having problems when I take greyscale images to the printers as my files are still in sRGB. I am converting to greyscale in develop, and the exported jpgs are greyscale but still in sRGB. How do I export in greyscale please? There is no option for this in the drop-down for export colour space.
I am just using Lightroom, but I do have the LR2Mogrify plug-in.

sRGB it just uses the three channels to hold the information. LR doesn't export to greyscale. If you have a particular printer profile that uses a greyscale space then use the print module and attach the profile there..

Help with exporting and image size or boundaries?

I am trying to slide the cat into the scene a little at a time foir an animation project I am working on. However, when I export the image the back ground of the image expands with a checkered back ground( showing here in white) and shows the whole cat.
How do I just show a little of the cat on the image at a time when exporting. I am trying to give the impression that the cat is walking into the room. I do not want to have to cut the cat up.
I would be thankful for any suggestions.

Provide the name of the program you are using so a Moderator may move this message to the correct program forum
This Cloud forum is not about help with program problems... a program would be Photoshop or Lighroom or Muse or ???

When exporting files to web pages Aperture keeping losing files, so for instance, if I choose to export 600 images to a new web page, it might do 524 images but not the full 600. I've tried resetting Aperture, it's the latest version etc etc. Help please!

If anyone can help me with this I would be seriously grateful.
When exporting mutliple files to web pages Aperture keeping losing files, so for instance, if I choose to export 600 images to a new web page, it might make 524 pages but not the full 600. I've tried resetting Aperture and its persmission and am using the latest version of 3.
I have 3600 images which I need to upload as sublfolders, each with their own URL and at the moment Aperture is dropping of anything from 1 to 90 images.
This is critical as people need to see each and every on of these images online. So if a file has 600 photos in it, Aperture should make a URL with 600 full image pages. And this is what it's not doing. On small files, say 30 or so it seems to work well, it's when it gets to more than that the problem starts.
I've used Aperture in the past under previous versions and not had this problem.
Any help would be great.
Thanks.

Hi Jack,
Thanks for responding (as it seems as though no one else has been able to provide any insight as of yet)! Not sure if you saw my recent post, but the version of Aperture on the 2008 MacBook has been upgraded to 3.1.2 (not sure how; I bought it in 2009, but only have OS X 10.5.8... which apparently can't house 3.1.2 of Aperture, but hey, like many other anomalies i'm encountering, I'm no longer surprised!). I am unable to upgrade it any further, as it warns me that my OS X does not fit the requirements. I exported the projects as libraries; however, like I posted before, apparently these are from too old of a version for the new Aperture (3.3.1) to handle and import.
It's getting to the point where I'd almost pay to upgrade the OS X on my previous MacBook (10.5.8) to something newer in order to THEN update Aperture to a newer version; however, my previous MacBook simply cannot handle this (the specs are awful -- hence my decision to save up and upgrade to the newest MBP with Retina).
I've spent hours upon hours transferring files, libraries as projects, previews, versions, even masters (though, apparently some of them aren't accessible?) with no luck. I've rebuilt the library and reprocessed everything. And this is all after having to return one MBP already since Aperture 3.3.1 is glitch-y as it is, and froze everything for having a "managed library". So, now that I know that I have to deal with a referenced library in Aperture... I just need to actually transfer my previous library to my new one (hopefully WITH adjustments since these are years worth of photos and work).
Again, any help is appreciated. I've lost enough sleep, time, and vision health over this at this point.
Also, I know Migration Assistant is an option, I was told that it wouldn't work properly anyway because of the different operating systems, and the potential for problems.

How do I paint accurate grey levels between 0-254 in an alpha or a greyscale image? Seems impossible ... Works in 5.5 .. not in CC. Bug?

So here's the thing . I need to be able to assign accurate shades of grey in an alpha channel as our code takes the value (between 0-244) and uses it to do its thing. I assumed this would be easy .. just choose your colour and paint .. but not so.
In an alpha channel, or even in a greyscale image, make a selection and fill it with RGB 6,6,6. Since there doesn't seem to be a way to get a greyscale pallette or input the value for Alpha this is th eonly way I can see to do it.
Now, using the info panel, check that it is indeed RGB 6,6,6. It is.
Now, make another selection and fill it with RGB 7,7,7. Check this with the info panel and ... its 6,6,6.
OK so now use levels or brightness to try to shift that 6,6,6 upto 7,7,7 ... check it with the eyedropper color sampler tool .
What you'll find is that the RGB value will go from 6,6,6 .. to 8,8,8 to 10,10,10 it's impossible to make it 7,7,7 or 9,9,9. Theres a whole bunch of other values that are also impossible.
If you do the above in any of the RGB channels themselves it will work fine .. its just the Alpha and in a greyscale image.
On a similar vein, on a regular layer, fill an area with you RGB 7,7,7, copy it and paste it into your alpha. Looks fine .. until you use levels to increase the contrast and you'll find that what was 7,7,7 is now a noise filled mixture of, I assume, 6,6,6 and 8,8,8.
( NB. As a note the above also happened in CS5 but in an old version of Photoshop 5.5 it works perfectly .. I can give the RGB 7,7,7 and the value thats painted is 7,7,7. Bring it into CC and its fine. So its just the creation of tones in CC that is wrong.
Also, it works fine if you edit the individual RGB channels .. you can get 6,6,6 AND 7,7,7 .. but as soon as you copy and paste it into the alpha . .the 7,7,7 reverts to 6,6,6 )
So
Q1 .. what am I doing wrong?
Q2 .. if 8bit alphas and greyscale images can have values ranging from 0-254 .. then how do I define the value I actually want? I can't use the K value as that's only a percentage so has fewer increments and there isn't a separate input for alpha value.
Q3 .. or put it more simply .. how do I set the grey value to a particular number, eg. 7
Thanks.
Pat

Thanks Herbert. I'll have a good look at Photoline.
I don't know if these have anything to do with it but
the first is the color settings from CS5,
the second is the default from a demo install of CC14. I see the gamma tickbox but it doesn't refer to the alpha.
the thrid are the colour settings of PS 5.5. Note this is the one that gives the correct ( with respect to my expectations ) result

I still use Aperture 2.1.4. I need to export an image file with a CMYK profile. Whereas a generic CMYK profile is listed in ColorSync Utility, it does not appear on the list of profiles in the edit portion of the export preset dialogue. Help?

I still use Aperture 2.1.4. I need to export an image file with a CMYK profile.

Is there some way to add the CMYK profile to the list of choices that are available in the export preset dialogue such that I can choose it?

leonieDF
Thanks for your response. My profiles are located within color sync utility as you can see here:
These profiles do not respond to clicking and dragging. Since they are all in one place, more or less, I'm reluctant to make further attempts to relocate them. Accessing the CMYK profile is the first difficult experience I've encountered with this arrangement. I have never needed the CMYK profile until recently, and that need has now past. However, it remains a mystery to me as to why it does not appear with all the others on the menu of export choices in Aperture 2, or on the menu of profile assignment choices in the Preview application (where again all the other profiles are listed as choices). I'm beginning to think my current set up will permit me to view an image that was created in CMYK space, but does not easily assign, or convert to that space. I don't face these restrictions with all the others, so it remains a curious circumstance for me. I anticipate upgrading my computer and software in the near future which might alleviate this issue altogether. Again, many thanks for your attention to this matter. The reach of this community is astounding.

Flash CC crashes every time I try to export an image

I just downloaded the free trial of Flash CC because I wanted to test it out as a drawing program. I just finished an illustration and want to export it as a .JPEG, but every time I try, Flash crashes! I tried creating a new file and just exporting an image of a small circle, and even that caused the program to crash.
I don't want to have wasted a free trial and be unable to use or access these images after the trial runs out, simply because I cannot export them into image files.
Any help would be wonderful, thanks.
(I am using a desktop Mac, if that makes any difference)

Are you on Mac OSX 10.6? Flash Pro CC is not supported on Mac 10.6 and this crash is one of the known issues on Mac 10.6.

How to export antialiased images of PDF pages?

Hello all:
I recently upgraded to Acrobat XI, and I am surprised to see that you STILL cannot export (or Save As) PDF pages to images that are ANTIALIASED!? Does anyone have a simple answer for this that doesn't involve a workflow of more than 5 steps? This is so headslappingly obvious a need that I'm at a loss for what Adobe's engineers are thinking when programming the Save As Image functions...
I posted this question all the way back in 2009 (see post at http://forums.adobe.com/message/2411677#2411677), and still the answer is the same: when Acrobat saves pages as TIF or JPEG files, they are ALIASED. Who would want that? Who?! WHY?
It's simply exasperating that Adobe does not include a tiny, little check box that says "Antialiased" in the "Save As TIF / JPEG Settings" dialog box where you set all kinds of parameters like resolution and colorspace....If the exporting process would just include antialiasing, you could set the resolution you desire and YOU'RE DONE.
But, as far as I can tell, you still have to perform some kind of gymnastic routine like:
Open the PDF and select all the desired page thumbnails to export.
Right-click and choose Extract Pages. Make sure to check "Extract Pages as Separate Files."
Export all the separate PDFs for each desired page into a folder somewhere.
Open Photoshop and start recording an Action.
Open one of the PDFs and specify the desired resolution.
Save it in a desired location in an image file of your choice (TIF/JPEG).
Stop recording the Action.
Delete the resulting image you made of the test PDF page to avoid an overwriting error later when running the batch (or check box to overwrite in batch dialog).
Run the Action in Batch mode on the entire folder of separate PDF pages.
This is preposterous.
Adobe, please get the simple things right for everyday low-level users before adding feature bloat to Acrobat with each passing version. Please.

Hi Dave: Good points about reducing feature bloat and installer footprint taking priority for most users...
However, if, as you say:
Acrobat and Adobe Reader are developed as a standalone product family....
Ultimately, since you can get an AA bitmap of a PDF file by just opening it in Photoshop etc., there is very little commercial demand for Adobe to include that feature in Acrobat.
then, those people who do not have Photoshop (because AA is designed to be standalone, right?) cannot access antialiasing in exporting PDF images at all! Your point is exactly my point.
If there is so little demand, then why include Export to Image functionality at all? Just eliminate it completely to save installer footprint space!....But, then, I'm sure you realize people would complain about that immediately, no? So, again, why include it at all when it's only able to export aliased images which virtually nobody is going to want? That's very passive-aggressive toward's Adobe's users. Nobody really benefits from half-baked features only begrudgingly included in software to placate the vocal minority of users who would otherwise miss it. I realize this isn't a huge issue for most users, but I think this points to a larger mentality within Adobe and the software industry in general....
There is a huge number of people working in corporations that own legacy versions of AA who have not and will not likely subscribe to Creative Cloud! (e.g.: The 100-person architecture/engineering firm I worked at for 10 years had one copy of Photoshop on a community graphics workstation and made everyone use a sign-up sheet to access it.)
Also, it's nice in theory that PDFs are supposed to be a print format. But, many many times, AA users have to make images (for PowerPoint, blogs, client portals etc.) from PDFs that they did not originally create and do not have the source files to recreate or export as images from their originating software. PDF export to images from Acrobat is their only choice without access to Photoshop.
And, if AA is truly designed to be a stand-alone product, untethered from the capabilities of the entire suite of functionality across Creative Cloud apps, then a modular plug-in approach to controlling feature bloat would be more appropriate, no?
For example, AutoCAD is a giant, sprawling application for technical drawing. And AutoDesk has recognized over the years that AutoCAD is used by many industries, each with special needs unneccesary to other industries' user base. So, they've created add-on packs of plug-ins that transform vanilla AutoCAD into AutoCAD for Architecture, Civil Engineering, Electrical Engineering, Bridge Design, Home Building, etc....see where I'm going?
And Adobe has a far larger installed user base for Acrobat than AutoDesk does for AutoCAD! How about plugins like AA for Technical Publishing, AA for 3D modeling, AA for Presentations?...

How to hide the file name (the bizarre number assigned by the camera) when exporting an image version in aperture from an album. Pl understand I want to keep the file name in the project library version.

how to hide the file name (the bizarre number assigned by the camera) when exporting an image version in aperture from an album. Pl understand I want to keep the file name in the project library version.

Within Aperture you have Images, which are constructed on-the-fly from two files (the Master and the Version). You get an image-format file _only_ when you export an Image. You select the file name (usually a scheme) when you create an image-format file (that is, when you export). Look under "Aperture→Presets→File Naming" for built-in Presets. You can, of course, create your own or customize any provided.
The Preset is applied to only the file newly created by your "export" command. It is not applied to the Image in Aperture (unless you rename your Versions or your Masters).

Orgchart export to image: special characters issue

Hello,
Using Orgchart Accelerated 2.01.
We have an issue when exporting to image. The issue happens when org unit name or attributes contains some special characters like é or ë (common in French). In the jpg export, these characters are being replaced by some square characters. In the preview and in the application, everything is displaying just fine.
This doesn't happen for ppt export (pdf export still not functionning)
Thanks,
Laurent

HI Laurent,
This is quite unusual. As far as I am aware the OrgChart Accelerated solution only supports English at present. However, you should raise an OSS message via Service Marketplace as I would expect it to export these characters okay.
Many thanks,
Luke

How to export all images as 4x6?

Okay, one of the things I absolutely love about Aperture is the ability to export many different versions for different purposes. As a wedding photographer, there are many different purposes to export for.
Here's the glitch that I'm running into though. We've now started only giving DVD images to our clients sized as 4 x 6s at 300 dpi. Anything larger, we'd like them to purchase through us to maintain quality.
I've been trying to figure out a way to get Aperture to export the images we've edited out as these 4 x 6 at 300dpi, but for the life of me, I can't seem to get it right. We crop at 8 x 12 so the ratio is fine, but getting it to come out right it a bugger.
I can't tell it to export at 4 x 6 because that only works for portrait and not landscape orientation. I can have a different export for each orientation since I have to maintain numbering consistency with our web galleries and their DVD copy.
I finally ran it out at 50% of original size, but hardly any of the images come out at 300 dpi. Aperture is just not doing everything I assumed it would.
Any ideas?

Set up an export preset as follows (from memory, so I apologise for any slight wording errors):
Duplicate JPG Original size preset and rename something like 6x4@300
'Size to' 'Fit within Inches' Width 6.0 Height 6.0
'DPI' 300
sRGB colourspace
Because all your images area already cropped to the right aspect ratio (3:2), setting size to 'fit within' will make the longest side 6 inches at 300dpi. It doesn't matter whether they are landscape or portrait. I have done it and it works perfectly.
If you have different aspect ratios and want to crop to 3:2 then export automatically, that is more tricky, but I don't think that is what you want.

Exported iPhoto images not showing in folder

Hi,
When I export a group of NEF images from iPhoto 06 Library, as JPG, to a new folder the files do not appear.
If I repeat the export for the other export options the images appear.
I did repeat this exercise and exported the images as JPG onto a USB drive, and was able to see them listed when viewed on another laptop.
Any suggestions?

Hi,
I found that if I set the image size for the JPG, then the files are visible.
Does anyone know why the files are hidden when the size is not defined?
Thanks.

How can I minimise the file size of a greyscale image ?

Hi,
What methods are there for making as small as possible the file size of a greyscale image. I need to keep the resolution at 200pixels per inch. The image is going to be big, 5835mm wide and 1780mm tall ! Some of them have some fine soft detail so I need to keep an eye on how that degrades. Others are better.
Can the same work for colour images or are there different approaches for those ?
Thanks
Envirographics

My need is to enlarge up a plan for placement in, then tracing over in a CAD program, retaining the fine detail prior to tracing. I have some at 1/10th the full size item at 200ppi, others still as digital slr raw files. I have found that less than 200ppi the detail starts to go. considering this, if I am now working full size item surely I would need 200ppi also ? I could try simply enlarging it up 'as is' but would imagine when I am zoomed in that the ability to work closer in would be lost as I would be seeing great big pixels. Certainly taking an image currently raw and making it 200ppi and 5800 wide would give me better detail retention.
I had hoped for some suggestions on how to save at lesser colour or grey numbers than 256. Some scanning of large plans can for storage purposes use 17 colours for example. Do I need 256 shades of grey, can I save as 64 shades perhaps ? Certainly LZW is the right direction here, retaining detail but using compression. JPG compression starts to frogspawn the edges below quality 6, so losing detail again. What about png or gif, thats what I had hoped for. Does anyone know how to reduce colour palette numbers to 64 or 32 shades ?
