Images transferred to iPad New (3) are smaller than original images

I have a few hundred 10 megapixel JPG images that take up 4.7 gigs on disk.

When I move them all to the iPad 3 they take up only 2.6 gigs on the iPad.

If i move the same images to the iPad 1 they take up only 1.1 gigs on the iPad.

It looks like the iPad 3 is doing some sort of image compression on the images thus reducing quality.

While it is doing much less of this then the iPad 1 it is still doing quite a bit of it.

Anyone have any way to avoid this or have any comments about it?

Photos are "optimized" for viewing when you sync them from iTunes to your devices, there's no way around that.

Due to the retina display on the new iPad, the size of the photos is bigger, the pixel resolution of the original iPad screen does not need that much info, that's why the size of the photos is reduced as well.

Because you can pinch and zoom around an image on both devices with ease. All the detail could be used on both device. While I can understand the optmized concept would be fine for many and should be the default. This is an issue for photo professionals.

Having such an amazing screen on the iPad 3 and then not allowing people to take full advantage of it as a way to view high quality photos without reducing the quality (optimizing) is a shame.

The quality of your photo is also made up by the pixels of photo and the screen you're viewing the photo.

So the ideal photo size for the new iPad would be 2048x1536 resolution. If your 10MB photo is at 3892x2586, you don't have enough pixel on the screen to show all info of the photo.

Again as you can pinch and zoom you could see all the pixels if you zoom in on any ipad. On an iPad 1 you would have to zoom in more because the native display is a lower resolution.

On any PC/Mac with any resolution monitor you always have the choice to zoom in and see your image at 1:1. Also in the iPad 3 i noticed it is not lowering the resolution of the images. They are still 10 megapixel images they are just doing more JPG compression then I would like.

There's a $1.99 app called "photo" from Smalltalk Consulting that will allow you to view JPG large files. I'm viewing files that are 8000x8000 will no loss in quality. You can zoom in to see the tiniest details. They also have one for viewing large tiff and pdf files.
