What are your workspace settings? They are shown underneath the image preview in ACR.
Thank you for responding; if I understand what you are looking for
Adobe RGB(1998); 8bit: 3504 x 2336 (8,2mp) 240 dpi
I am running windows 7 on a 64bit machine - if that helps
I just saved a low quality jpeg of 8.2mp and the resulting file was 670kB, so 7MB is way out. Saving at maximum quality produced a 5.8MB jpeg.
The fact that your raw files are also around 7MB suggests to me there's a connection, and maybe they are somehow being embedded in the jpeg. Are they always a similar size to the raw files, and which is bigger, if any? It's strange that creating develop settings will cause the problem, and I doubt that Camera Raw can generate 6MB of metadata to embed in the jpeg.
A first good step would be to make sure you are running up-to-date software. If you are running CS5, you need to update Photoshop 12.0.4, and Camera Raw to 6.4.1. If you are running CS4, you need to update Photoshop to 11.0.2 and Camera Raw to 5.7. Just doing this maybe enough to fix the problem.
Very grateful for something to try - I am running CS 4 will try updating and let you know how I
A JPG with quite a bit of high-ISO noise or very fine, high-contrast image detail might not compress very well.
If you have an offending RAW, you can post using www.yousendit.com or www.dropbox.com or some other such website, then others can try it to see what happens for them.
Thanks to all of you that have replied much appreciated. Problem still not fixed however, I have updated all software to latest versions of CS4 and ACR. but still having the same problem, probably worse in fact as a 7mb file has gone upto 12mb !! even at low quality jpg (3).
Somone has mentioned default compression ratios - does anyone know where I can find this and what the correct settings should be
Please upload a sample raw and sample jpeg to a file sharing site. It might be a lot easier to diagnose than feeling around in the dark.
Thanks Yammer I have created a dropbox account and posted the 2 pics - what information do you need to be able to access the files ??
A link to a download page?
Sorry all a bit new to this - hopefully these will work
I saved the image as low quality jpeg, with and without settings, and got a perfectly reasonable result. Both images were under 500kB.
Opening the file in Photoshop, it says it is a 1.56GB (!) file, 28063 by 19843 pixels - that's a 531MP image!
Camera Raw is somehow resampling the image 9.23 times bigger, producing a file with 85 times the number of pixels, even though you have workspace settings size set at standard.
There something seriously wrong with your Photoshop setup, and I don't know what to suggest next, other than obvious stuff, like checking you don't have multiple versions of the plug-in, etc.
Thank you so much for taking the time to look at this problem but .... Yak - don't like the sound of what's going off !!!
Will look at the plug-ins if I can find them. Could it be anything to do with windows 7 64 bit or having two installed versions of photoshop ??
I use Windows 7 64-bit with no problems. Two versions (eg CS4 and CS5) of Photoshop could be causing complications, but I don't recommend removing one of them, as this can sometimes break the other - unless you are referring to the 32 and 64 bit versions of the same package, which shouldn't be a problem at all.
The plug-in is called Camera Raw.8bi, and if you're on 64-bit windows there should be two
64-bit in Program Files\Common Files\Adobe\Plug-ins\File Formats\
32-bit in Program Files (x86)\Common Files\Adobe\Plug-ins\File Formats\
There are also alternative locations at:
Program Files\Adobe\Adobe Photoshop CSx\Plug-ins\File Formats
Program Files (x86)\Adobe\Adobe Photoshop CSx\Plug-ins\File Formats
and you should check that Camera Raw is not there, as these are Photoshop-specific folders, and Camera Raw is common to all CS applications.
You may well have to switch on the Folder Option to 'Show hidden files and folders' to locate the plug-ins.
You can also check what Photoshop sees by selecting: Help > About Plug-In... and you should see just one copy in the list. Clicking it will tell you the version installed.
I have checked the plugins and all seemed normal. I have re-installed again and updated and re-checked the plugins again all seems normal but still having the same problem.
Thanks again for trying.
Hi I have been doing more digging on this and have found
out the following:
As per Yammer - if i go through the same editing process in ACR on a different machine the file size reduces in line with what you would expect.
I also tried taking a 300KB image and cropped it in paint on my machine the output file size grew by a factor of 4 to over 1.2mb
When the same image was cropped in paint on the alternate PC the image size reduced - as you would expect.
Based on this it appears to me that there is a problem with my pc and not with Photoshop ??
Does anyone have any ideas please.
What happens if you save as Medium quality?
What happens if you save as TIFF?
You never clarified what you meant by "two installed versions".
You say you have "re-installed", but does this mean you just ran the uninstall, and then installed again? If so, you may want to google for a more thorough method, as I am fairly sure that Photoshop leaves files and registry entries behind after it's removed. Besides, you said there were "two installed versions", so what exactly are you re-installing?
Thanks again Yammer
If I save as medium quality file size goes higher - over 13mb
Saving it as an uncompressed tiff sent the file size upto 1.5GB !!!!
The two installed versions were the 64bit version and the normal (32 bit ?)
I did uninstall and delete Adobe folders before reinstalling but as you say there may have been files left behind - will look into that
I paid £30 to adobe for there technical support - but getting nowhere at present as with their basic level support I think I need them to escalate to more qualified people.
I am wondering if the problem is with my pc due to the upscaling of file size when edits were done in Paint
I am wondering if the problem is with my pc due to the upscaling of file size when edits were done in Paint
Erm ... what?
Where does Paint come into this? Aren't you just saving a raw conversion from ACR?
Please see couple of posts above. I tested cropping the same image in paint to see what would happen - again the file size increased x4 when it should have got smaller
Hope this helps
So you're saying that any graphics application seems to be going wrong on the problem PC? Was the cropped Paint image upsampled too?
If so, it seems that a wayward Windows API may be the source of the problem, which surprises me, as I thought that would all be handled by the software itself.
Things to check/reinstall: imaging components, APIs, codecs and potentially-conflicting graphics applications/viewers, etc.
It looks like a long haul. If it was me, I'd start working through my list of applications, removing/disabling and/or updating things until it fixes the problem.
Bitmap resizing can be done by a video card, so perhaps there is an issue with the drivers or the card, itself, if Windows is offloading some of that processing to the card. Updating the drivers or fiddling with video-card tweak applet might do something, too.
Something I didn't see touched-upon as I skimmed through the thread (apologies if I missed it...).
Image CONTENT can affect JPEG compression greatly.
If the image, for example, has a high detail content (and/or a huge amount of noise) a JPEG can take a very much larger amount of space than one that's smooth.
Can you post one of your images? Since they're large, perhaps use YouSendIt.com to send it to yourself, then provide the URL here.
Did you do a apply a crop in Camera Raw? If so, what are the crop settings? [Custom crop settings are the only way I know of to make Camera Raw generate a file that large.]
Hi to everyone helping with this and many thanks.
I have not had chance to look at the graphics card issues but will do.
I have posted links to images down loaded to dropbox have you spotted these above - if so are they ok ?
I am using a custom crop size - set to A4 will try using standard crop does this really cause such a problem ??
I really dislike DropBox... I was never able to get the JPEG you posted from your dropbox links:
- An attempt to visit your first link yielded an error with an image of a box with chains around it.
- An attempt to download the CR2 file with IE9 yielded a mutipage 8 megabyte .TIF file instead with 1728 x 1152 pixels that Windows Photo Viewer could open but IrfanView could not.
- However, I was able to download it as a .CR2 file with FireFox. I was then able to open it with Camera Raw and save a JPEG directly as a 3504 x 2336 pixel JPEG, which came out to 1.9 megabytes at maximum quality. This confirms there's nothing fundamentally wrong with your raw file.
- I couldn't see the JPEG at all in IE9, just an immediate "broken image" icon.
- I was able to start downloading the JPEG (an image of some sailboats) with Safari VERY slowly, and it was showing on the screen, but it crashed the browser somewhere under CoreFoundation.dll before completing.
- FireFox reported "The image "http://dl.dropbox.com/u/36474065/edited%20file001.jpg" cannot be displayed because it contains errors".
I'm starting to wonder whether it is possible you have some kind of malware infection affecting the encoding of JPEG files or the saving of image files on your system... What antivirus/antimalware solution are you running? Is it up to date?
Note that since you did not post a copy of your sidecar XMP file, the settings you used in your Camera Raw conversion cannot be reviewed.
Okay, I was able to retrieve the JPEG using a Gnu command line tool (WGET)...
- It's 13 megabytes and shows 28063 x 19483 pixels at 240 dpi in Explorer's Properties view.
- IrfanView opens it at 14032 x 9922 pixels. Apparently the full size is just too large for that app.
- Windows Photo Viewer will open it, but only after quite a lot of computation.
The large size of your JPEG files appears to be because the number of pixels is huge, and so the task is to figure out how this number got so large.
I think the best next step would be to post a copy of the .XMP file that contains the conversion parameters (assuming you're not using the central Camera Raw database to track your settings).
I've always wanted to know how to convert images directly to sizes larger than those provided.
Your probelm is the custom crop. You have the resolution set 240 pixel/inch, which is fine. But you set the size to 210 cm by 297 cm! Paper size A4 is 210 mm by 297 mm. So you set a crop size 10 times larger on each size (100 times more pixels) than you thought you did.
Didn't something like this crash that Mars polar probe some years back?
It takes the inventor of Photoshop to solve a user's off-by-10 error.
Yes, hats off to Thomas on this one for noticing the cm vs. mm issue.
Just goes to prove that no matter how sophisticated things become, there still remains room for simple, elegant errors too.
Guys you are all brilliant thank you so much for taking the time to look at this issue - I do feel dum !! The mars probe comment did make me laugh though !!
It amazes me how a bad crop setting affected ms paint too! :D
I must admit that is a puzzle but to be honest I never use Paint it was just a test. I am just V happy that ACR now seems to be working fine!
Thanks again for all your thoughts and advice
