Post your comments for ITunes Appears to Change Colors of Images Sent to the New iPad here

Maybe the heat produced by the ipad is causing it

You should pursue two paths: make a bug report at Apple, and while they are looking at it, make some tests trying changing/removing the color profile of the image.

I wonder if photos are affected in the same way if you upload them via the iCloud control panel (ie, through Photo Stream).

Hmmmm...why not use PNG for the photos instead and see what your results will be. PNG is a lose-less format vs JPEG. PNG won't lose any quality no matter how many times you re-save it.

It may also be a good idea to find out what ICC profile iTunes is using. I would assume it is using a profile that is found in Mac OS X. I would suggest loading the recent ICC into Windows and seeing how much it makes adjustments on your photos. See if they match what iTunes is using.

I noticed on my Windows 7 install, there is an Apple RGB ICC profile avail, but it is only for the display.

Apple does have ICC profiles avail. I Google Mac OS X profile downloads and there are links to older profiles from older OS X versions as well.

For any. Serious image going to an iPad, it's known that using iTunes isn't the proper way to go. Either use an SD card to connect the camera directly using the Camera Connection kit. Or, you can but a Compact Flash rare adapter from M.I.C.

Nothing is changed when images are transferred that way.

Dang! I made a bunch of typo's there, didn't I?

Yes, they are. We tested the same image going over iCloud to the new iPad (uploaded through Photo Stream) and the results were similar to the image that went through iTunes.

You need to get out more dude

watch your apostrophes
typo's is singular possessive, or short for the typo is
You want to use typos, the plural form

You're welcome

Open the files in Preview, Tools > Show Inspector, see what the ColorSync Profiles are, that could be the culprit too.

That is an interesting observation since my first thought was a simple white balance shift due to the differently colored backlight of the new iPad (it seems to be a little warmer than the old.) On the other hand, I almost never transfer files into the iPad through iTunes, choosing instead to use the SD card adaptor to import them from the camera whereas they export automatically through iPhoto or Image Capture to my PC.

Aren't they just getting changed to better colors?

Professional Photographers generally will color correct all their photos on color calibrated monitors using professional software. When they transfer their photos to the ipad so that they may show the photos to potential clients, they want to see the photo exactly as they edited it. NOT the way Apple's software thinks it should be.

Melissa, change your color profile to sRGB and report back.

[peterlee86]

"Another possibility is that iTunes is changing the color profile of the images it transfers. The metadata for the image doesn't report any changes, and yet the increase in color saturation is very clear across different monitors and operating systems, including Windows and Mac OS X."

This is what's going on. Testing of the new iPad screen by sites such as DisplayMate and Anandtech show that the new display has a much wider color gamut than previous iPad displays. Anandtech's measurement says that the new iPad displays 65% of the Adobe RGB color space versus 44% on the previous iPad displays and 94.4% of the sRGB color space, up from 63.3%. That's good but colors will shift if you display without adjustment jpegs that have more narrow color profiles on wide color gamut displays. It appears iTunes and the new iPad have been set up to automatically re-map the color profile of images so that they appear correct when displayed. That's why when you transferred your photos and view them on the new iPad, they appeared fine. What appears to be happening is that the remapped, wider color gamut is being saved with by the imported image so that when it's exported out of the iPad, the wider color profile goes along with it. That's why when you display an image after transferring it off the iPad, there's a pronounced color shift (you'd see this color shift if the iPad/iTunes didn't automatically the color profile in the first place).

The first rule of image compression is that compression, in and of itself, alters the destination image. This remains true across all software. Taking a 3.48MB original file and compressing it to 1.04MB translates to loss. Depending upon what factors the software weighs as most or least important is what determines where the loss will occur.

Images that must retain their original parameters "must" never be transferred with a method that alter the images. The supposed benefit of digital over analog processes is that digital to digital is supposed to retain the original information (it's that whole thing of zeros and ones). If every bit of data in the duplicate remains the same as the data in the original there is no change. If any bit is changed then you no longer have an accurate digital copy but a (are you ready for it) facsimile, instead. Each subsequent duplication with the same method yields a continued loss; much like repeatedly taking photos of a photo (film), each subsequent photo will lose a certain percentage of information from the photo before it.

As indicated in the article, to know what data is omitted would require knowing what priority the "sync" gives to what factors. But regardless, moving images with sync is not something that should be done for the purpose of retaining the original quality of an image. Then again, if you suffer from one of the many and various types of color blindness (like me), it really doesn't matter anyway.

I think there's probably an easy way out by removing the optimization option on iTunes or Photo Stream. Most people that use iPad aren't professional photographers. If they are then they should just turn that off or use an alternative way to save photos. I think professional photographers should inform themselves before buying an iPad.

I think I would be surprised if professional photographers want to use sync with no Data loss. I think if you own an iPad and you are a professional, it's worth the trouble to invest on an adapter for cameras and SD Cards. You might even consider keeping your photos on the SD Card only and open them from there if you want zero risks of compression.
