Wrong embedded colour profile causes huge jpg files when published to .Mac

D'oh! i posted the following on the iDisk discussion my mistake. Here it is all again for iWebbites:
I've spent most of the day trying to optimise my new iWeb site on .Mac but the published jpg files are far too big.
Despite sizing to 800x600 px and jpegging at about 5 or 6 in Photoshop which resulted in a file size of about 100kb on my local disk, when uploaded to .Mac via iWeb the they have turned into 800 kb files.
Lots of trouble-shooting, including ensuring that they weren't converted to png, that they have no borders, reflections or drop-shadows yet they still got bloated on the upload. Especially the photos in the photo-gallery page.
I've isolated the problem but don't know what to do next:
Turns out, iWeb ignores the sRGB embedded colour profile and replaces it with the monitor profile of the originating computer.
I discovered this after I opened the file in Photoshop directly via iDisk in Finder. Converting or assigning the file to sRGB and saving it back down to iDisk immediately restored it to its intended file size of 100kb and this time with the correct sRGB colour profile.
Going now to the domain.sites on my local disk and opening the package shows all the photos doubled up. A 360 x 264 .jpeg file with the monitor profile embedded and bloated out to 800kb plus the original 800x600 image with sRGB and .jpg as the file type but still only 100kb
So what the heck is happening in iWeb to do this and to use the wrong file type associations with the wrong file when uploaded?
There is very little on the forum about colour (color) profiles and no mention of the bloat in file size, just a reference to colour and tone issues with the wrong profile so I'm wondering if its related to the 1.1.2 update. (I haven't really tried using iWeb until the last week or so).
Fixing the problem by post processing the photos on my site every time I publish would be impossible with the amount of photos I have and my intention of updating the web galleries regularly.
As you can find out if you go to a photo page on my site:
< <a class="jive-link-external-small" href="http://">http://web.mac.com/adrian_malloch/iWeb/AdrianMallochPhotography/ Kabaddi.html > some pages take horrendously long to load. Check out some of the other Subculture pages. I haven't tested them all but Safari Activity viewer shows that most of the slow speed is related to opening jpeg files.
Any help and informed suggestions would be hugely appreciated.

This is doing my head in.
My last two comments "posted" half way through writing, before I had a chance to edit completely.
Here's how it should have read :
Using sRGB as a monitor profile, in itself, doesn't make a lot of sense.
A monitor profile is custom made specifically for the monitor to compensate for its display characteristics.
A "good enough" monitor profile is to use the software calibration built into the Displays preferences. Go to System Preferences/Displays/Color/Calibrate and follow the prompts. Hint: squint as you try to judge the colour and tone differences. The idea is to make the detail so fuzzy you don't notice it.
It's not very accurate, especially with LCD screens, but it's better than nothing and certainly better than using a universal colour space like sRGB, etc.
The accurate option is to get hold of a hardware calibrator like the Spyder, or Gretag-McBeth iOne Display (which I use). It costs a bit but is vital for accurate repeatable colour.
The whole point is that when the profile is made up and is set as the default profile, then you will get a WYSIWYG screen.
So, the same images will look the same on different monitors providing they each have accurate monitor profiles made specifically for them.
If you use sRGB as your monitor profile then you cannot expect the image to look the same on any one else's machine, whether they use sRGB, a monitor profile or any other profile. Worse still, if you change an image to "look right" on your screen, chances are that the image will look horrible on another screen.
Hence, why I will only switch to sRGB monitor profile as a workaround for uploading in iWeb. Nothing else!!

.jpg files created on iphone 4S are not recognized as .jpg files when uploading them to American Heart Assoc. website?

.jpg files created on Iphone 4S are not recognized as .jpg files when uplaoding to American Heart Association fund raising webpage? .jpg's from Canon camera uploaded without any problems? The website automatically reduces the file size to <100kb.

I haven't contacted AHA about this issue. The .jpg files created on Canon SLR uploaded correctly, but the photo from iPhone which was emailed to my PC using MS IE. The .jpg was browsed to from my desktop and is submitted. It shows up in draft form then when uploading it fails saying it is not a .jpg file or .png file? I have had other issues in the past emailing iPhone pictures. They were not editable after being sent to a PC. I guess we can retake photos with a non-Apple camera.

Hello.
when i am publishing a webRole,
process is failed because the values in the diagnostic configuration file do not match the Production profile.
the diagnostic file is for our dev env only.
is there a flag/attribute that can be used to ignore the diagnostic files when publishing with a specific profile ?
Thanks.

Hi,

Embeded Colour Profile

I search but I didn't see this topic so if I did miss it, I apologize...i actually looked in the manual with avail..
I import a lot of digital images from a Pentax ist-ds, K10d, and a Kodak coolscan. They all have different colour profiles that are not in agreement with my cs3 colour profile so when I import, I have to answer a question for every pic..this is tedious..is there anyway i can import a colour profile into cs3 (like noise ninja) or just have cs3 import the accept the profile that is in the image automatically ?
As well, importimg DDG images seems to be a two part process..can I reduce this down to one ?
Thanks
Ian.

In color settings set Photoshop to preserve profile.
then if you want the image to be in your work space you can convert to profile.

Color Cast Only On Mac Generated jpg files When Viewed In Bridge Cs3 Preview

Hi,
( Issue With Cs3 Bridge Viewing Jpgs - Getting Colour Cast on the Mac Generated Jpgs Files Only When Viewed In Bridge Cs3 On PC )
Using CS3 creative suite Mac & PC and viewing all files on the PC.
We have psd files when viewing in bridge they are ok and save jpgs via PS3 both on the Mac & PC off the same PSD file that we started with.
But when viewing these jpg files in bridge we get a red cast only when viewing from the Mac generated files from the same PSD we started with.
When we open the jpg files up in Photoshop all of them are ok we no issues only when viewing in bridge we get the red cast.
All PSD files have the same information content:
Bit depth
Colour space
Pixel size
Why are we getting this happening.
Thnx

Thanks very much for that lead, NormanPCN. I do have Auto Tone checked, though the rendered files in the example above do not have XMP sidecars. I will try unchecking Auto Tone even so, and post back when I see what happens.
Thanks again,
Kieren
EDIT: Bingo! I took Auto Tone off in ACR Preferences (in Bridge) and the non-RAW files immediately regenerated thumbs and previews. They now are indistinguishable from the PSD. There is still the very slight difference which I mentioned between the PSD and the CR2. While that seems odd, it is small enough to be relatively trivial.
Many thanks!

Is it possible to ignore and not import JPG files when a JPG and raw file of the same name exist?

Is it possible to ignore JPG files on import? I shoot raw + JPG and see no reason to keep the JPGs; I shoot JPG primarily as a backup (I back all the JPGs up online to my smugmug account then delete them before importing the raw files), but they're also occasionally handy if one wants to get a quick print in the field. I know that one can set a preference to "Treat JPEG Files Next to Raw Files As Separate Photos", but even then they still are imported.
As an example, say I have this scenario (not on DSLRS, but on pNs cameras, sometimes a JPG but not raw is captured - I suspect this has to do with how the buffer is filling) with these files on a memory card:
IMG_0001.JPG
IMG_0001.CR2
IMG_0002.JPG
IMG_0003.JPG
IMG_0003.CR2
When I import pictures from this folder, I'd like 2 CR2 files and 1 JPG to be imported. I'm even willing to copy the relevant files and drag and drop them onto LR's Library module. But even if I do that, all five files get imported. Thanks!

No, I don't believe that's correct. As I said in my previous post, Lightroom's Import is a two-stage process.....first copy the files from the card, then when that is finished, render whatever previews have been requested.
AFAIK there is nothing unusual about my system, Lightroom has always imported in this two-stage way as far back as I can remember. Based on this I see no 'safety' benefit from copying files first outside Lightroom, then using an ADD import process. On the contrary, as this takes away the possibility of using the "Second Copy on Import" option, as well as having to manually setup import folders, I see nothing but downside from that approach.
Mea culpa, Jim is correct! I checked my Windows 7 system with LR4.2 and I monitored the 'Destination folder' during an import direct from memory card to hard drive. 'Copy and import' showed in the progress bar until all image files were visible using Windows Explorer in the 'Destination folder.' Only after all files had transferred did the progress bar change to ‘Render 1:1 Previews.’ I started using LR1.0 on a Pentium 3 single-core system with Windows XP 32 bit, which I think is when I made this observation. Regardless, it is clear that LR4.2 is using a two-step import process. Thanks Jim for being persistent!
It still begs the question why some people are experiencing very slow imports, damaged image files, and other related import problems from memory cards? My guess (and it's only a guess) is that they have 1) 'Rename Files,' 2) 'Automatically write changes into XMP,' or 3) 'Include Develop settings in metadata inside JPEG, TIFF and PSD files' checked in LR preferences. It would be a good idea for anyone experiencing import issues to try an import with these three (3) options unselected.
My apologies to the OP DBarman for going off topic. Hopefully the extra information and observations are helpful.

Aperture does not import Nikon JPG files when RAW and JPG

I own a Nikon D2x that I download files to a Sony 40GB portable HD. When I shoot in RAW + JPG only the RAW file is imported when I connect the Sony HD to my Mac and import to Aperture.
If I open the Sony disk Icon on the Desktop, I can see both the RAW and the JPG. In fact I can finder copy both files to the Desktop with no problem.
Even when I connect the camera itself, the jpg files are not imported.
This makes me think I should just shoot in RAW and save the space on the memory card.
Why does Aperture not import the JPG files?

it does import them ... but only displays the RAW file ... if you drill down into the library package you will see them ...
here are threads dealiing with same issue ...

Iweb won't play my audio files when published

Can someone please help? I spent hours creating a website for music i produce. It works all fine and dandy on the preview pages, but when published the audio files and video files don't play. All that comes up is the picture and a small quick time player logo underneath. I have tried several different remedies but nothing seems to be working. Is this just difficulties with the new me.com facilities or what? Any help would be gratefully recieved.
Thanks very much,
a very frustrated mac user.

I gave up on your page because the file size is absurd.
Your source files are AIFF format (raw CD quality audio) that measures 10 MB's per minute. I don't have the time to wait for 6 of these files to load in your single page:
http://web.mac.com/thekoles/the_koles/Media/trouble%20and%20strife%20150808%202. aif is 47 MB's.
Compress your files in iTunes to reduce the file size.

How to view files embedded colour profile

I retouch all my images in photoshop from lightroom so they appear next to the raw file in lightroom when I come back. Depending on where the images will be printed they can have a different embedded profiles. without having to include the profile used in the naming of the file my question is:
Is there a way of viewing the file's embedded profile from within lightroom without having to re-open in photoshop to see?
cheers
mike

No, there isn't.
The only way I can think of is to write the color profile into the file name that is visible also in the Loupe View and Develop Module if you set the the View Options accordingly.
You also could create Collections for each color profile, or you could assign keywords (i.e. "sRGB"; "AdobeRGB", etc.).

From Lightroom 4.4 RGB1998 - open in photoshop CS6 - embedded colour profile changing to SRGB regardless of Lightroom export settings.

Hi,
I'm experiencing an issue regarding lightroom 4.4 - Photoshop 13.0.6x64
This has just started happening in the last few days, I have not changed my settings etc ?
My external editing preferences in the Lightroom preferences menu for the edit in Adobe Photoshop CS6 command are
as follows,
File format    - TIFF
Color Space - AdobeRGB (1998)
Bit Depth      - 16 bits
I run CS6 working space in ColorMatch RGB at the request of the Pro lab I use & have done for years with great results. Before the file opens in CS6 I
get the Embedded Profile Mismatch pop up & I alway select use the embedded profile ( AdobeRGB1998) instead of the working space.
The mismatch menu always used to read,
Embedded : AdobeRGB 1998
Working : ColorMatch RGB
For some unknown reason every file I now open through Lightroom into CS6 - The Embedded Profile Mismatch warning is telling me that all my files
have an embedded SRGB IEC61966-2.1 profile ?
I can't get any of my files into photoshop with my normal AdobeRGB1998 embedded profile anymore regardless of Lightroom's external editing settings?
Seems they are being converted regardless ? have tried removing CS6 preferences Doc from the folder but not making any differences. Even my old files
that I know are RGB1998 embedded are turning up in CS6 converted to SRGB IEC61966-2.1 profile ?
I'm running a Mac 10.9.4, Lightroom 4.4 & Photoshop CS6 - 13.0.6 x64
Any ideas on how this started & how I can sort it out ?
Thanks,
Will.

Is ACR being used to render the images instead of LR? Open an image in the Camera Raw plug-in in Photoshop and check the Options at the bottom of the ACR plug-in that include bit-depth and color profile.

Conversion of embedded colour profile

Hello good folk. I have an HDR image that I processed in Photomatix which I saved with an adobe RBG profile that I now have in Lightroom. Lightroom see's it as it should but When I tried to edit in photoshop even with the honour embedded profile ticked it still looks all off. I now export from Photomatrix as SRBG and there are no problems there. However this one photo (which is very important to me) Im having trouble with. Is there a way to change the profile to SRBG without affecting the image or could someone please advise me the best course of action. thank you for your time. Richard

Try opening the file in Photoshop and then use the Assign Profile (not the convert profile) option to assign sRGB to the image.

ACR converting raw into huge jpg files even at low quality

Hi Need help !!I am downloading raw files from canon 30d into bridge and processing RAW files in ACR.
When i have finished the edit I am clicking on save image and selecting jpg and then low quality. The RAw image is about 7mb and the converted low quality jpgs are also coming out to 7mb. These are far too big and is only a recent problem. I have re-installed photoshop but this has not fixed the problem.
By the way if I convert an image from raw that I haven't edited by the same process the file size is only 300kb
Would be very grateful if anyone has an answer to this

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
Cheers

Export as JPEG with embedded colour profile

I want to save my raw image as a JPEG and tag the picture with a printer-specific profile, so I can send to a 3rd party printing company. I have a copy of their profile and placed in the appropriate filder on my system but when I do the export, this profile does not appear as an option in the Color Space drop down. I only get the 3 options as stated in the manual.
"Color Space Converts the photos to sRGB, AdobeRGB, or ProPhoto RGB color space and tags the photos with the color profile."
Is it possible to do what I want with Lightroom? Is there an equivalent of the PS convert to profile facility?
Thanks
Lee

What you can do is to create an action -- or better yet, a droplet -- for Photoshop that will provide this conversion to the destination space of your choice. Then you do an export from LR to a 16-bit ProPhoto TIFF, then drag your exported images onto the droplet (which is responsible for the color space conversion as well as dropping down to 8 bits if required). The droplet can help speed up the process if you have lots of these images to do.

JPG files not opening on MAC

Hi Guys,
I went for a trip in the last month where I clicked a lot of pics. I initially transferred them to my windows laptop (JPG). After that, I transferred them to mac and when I view the same files in mac the pictures apear to be in .jpg.xml format (How is that possible?). Anyway, i converted them to JPG and still applications (preview and iPhoto) give me error in mac. I initially tried to open it from external hd itself and then even tried copying it on the desktop. But nothing happens. I was of the view that we can open jpg in mac and if i am unable to do so its going to be a big pain for me.
P.S I am new to Mac so I need your assistance with the same.
Thanks. Usama

After that, I transferred them to mac and when I view the same files in mac the pictures apear to be in .jpg.xml format (How is that possible?).
That is something you did in transferring the photos - it does not involve the Mac - exactly how did you transfer the photos form your PC?

Center a SWF file when Publishing

I have been using Flash for a while Flash 8 and now Flash 9. I dont know too much about the program, someone wrote the program for me and I update it. When ever I publish the Site to upload to my server I have to go into the HTML file and insert <center> twice to get the site to be center on the web.
If I dont do it the site is when viewed online gets left justified.
It is not a big deal to edit the HTML file but every time I do it I figure there must be some button i dont have checked in Flash to just do it automatically.
Seems like with such a huge and powerful program that must be an option that I am missing. Can anyone let me know to to automate this task.
Thanks
Aaron

If you find yourself doing something like this everytime, or most of the time, edit the Default.html file here: (duplicate and rename first so you can revert if need be)
Win:
C://Documents and Settings/USER/Local Settings/Application Data/Adobe/Flash CS3/en/Configuration/HTML/
Mac:
/Users/USER/Library/Application Support/Adobe/Flash CS3/en/Configuration/HTML/
Next time you publish your new myflashfile.html will reflect the changes.
