Not optimize photos?

You may be able to put full resolution photos on the ipods drive, but you cant view them. The only way to view high resolution photos would be in safari.
You know, that is really weird. I was just thinking about this today. I used to be able to show a photo on the iPhone and zoom in with the "pinch" and it would be so clear. Now after I updated to 1.01 (or whatever, the new update), it seems that my photos are really grainy when you zoom in and only look good in the normal view. Anyone else with this problem?
what file types are the files? i have a feeling that psd's and tiff's didn't get optimized before the update.
The only way I know is to attached the hi-res photos to a bookmark and use safari to view it... see this link for full details and script: http://www.insanelygreattees.com/news/?p=51
Whatever you are seeing was there before the update. Same resolution (640x480), same quality, same exact size.
Not much to zoom in on with a 640x480 image on a 480x320 screen.
Hopefully this gets addressed soon. It's akin to iTunes deciding that 32 kbps music is good enough and "optimizing" all music tracks to that bitrate. We should be able to have a way to specify image conversion size (up to and including no resizing at all).

it's really pissing me off, I have all 108 marvel civil-war comics that I just don't have time to read and being able to carry them around on my phone would help so much... as it stands now zooming in on unreadable text is worthless...
PS... syncable pdf would be nice too ;p...
I've been resizing my photos to 640xX (resolution is the same as the iPhone LCD) before uploading thinking I would be able to zoom in 1.5x without any quality loss. This isn't the case. Turns out the photos coming out of iTunes are 480xX. I'm probably better off resizing to 480xX in Lightroom since it is probably a better algorithm than what iTunes uses.
I also noticed that skin tones come out blotchy after the optimization.

I don't know what you meant by 480xX (I would assume 480x320) but the photos are "optimized" by iTunes to 640x480. Email a photo from the photo app to youself and you can see this.

No... actually it wasn't. I can clearly remember "pinching" and zooming in to the pictures and being able to see a MUCH higher quality image than I do now. I can't even zoom in a little before the image quality is bigtime diminished. FWIW I am using 8mp images so I know it's not a question of the original image.
BOO Apple! I am embarrassed to use the pinch to show people the images because they look so horrible (whereas before I was excited to use it!)
The photos on my iPhone are exactly the same size before and after both the iPhone and iTunes updates. They were 640x480 then and they are 640x480 now--no difference. This makes since as I would have noticed if iTunes suddenly resized 2778 photos--photos whose originals are from a 10 megapixel digicam. How can this be if the update mysteriously degraded them all?
Moreover I've emailed myself photos both before and after the updates and they average around 100-120 KB. That is not much compression for a 640x480 image. If they were averaging 100 KB before the updates and suddenly dropped to 50 KB after I might agree with you.
Also, since the iPhone's display is 480x320 whereas the photos in the Photo app are 640x480 your comment about not being able to zoom in at all makes little sense. Of course you can zoom in, as the original view is not 1:1. I am not saying I want 640x480 images but that doesn't mean I can't zoom in if they are.
Anyway if you can add any evidence to support your opinion that photos have degraded due to an update then by all means post it.

480xX means the longer dimension of the photo is resized to 480 and the other dimension is resized accordingly. In other words constrain to 480 while keeping the aspect ratio the same. It only comes out to 480x320 if the aspect ratio of the original is 1.5. I emailed a photo from my iPhone that I had uploaded. The size was 360x480 even though the photo I imported into iTunes was Xx640.
I exported my photos from Lightroom at 640xX (came out to 640x480) and 85% image quality. The filesize on my disk is 203kb. The file on the phone (emailed back to myself) is 640x480 and 111kb. Looks like all iTunes did in this case was to decrease the image quality setting (increased compression) which is exactly what I wanted. Zooming looks good as long as I don't try to zoom way in.
I then exported the same photo at 1080xX and 85% image quality which resulted in a 448kb file. The file from the phone is again 640x480 with a size of 109kb. It doesn't look quite as nice as the above although it is still perfectly acceptable. Another picture I looked at was 640x432 and 122kb.
For the fun of it, I exported the same photo as TIFF (970kb) and PSD (1.75mb). The files on the iPhone are identical are 640x480 JPGs with a filesize of 111-112kb.
So, regardless of what the original file is, iTunes is constraining the dimensions to 640 (as you said) and converting to JPG with an image quality setting to about 70%.
That is because you synced a portrait oriented image. Had the image been 640x480 it would have been 640x480 on the iPhone (though not the exact same 640x480 image). Conversly, had it been 4800x6400 it still would have converted to 360x480 on the iPhone. Seems weird but that's what appears to happen.
This is why I don't like syncing portrait images. Unfortunately the alternative isn't any better: if you try to view a sideways photo by holding the iPhone in portrait orientation the tilt sensor changes the view too. Wish there was a way to manually set the Photo app's viewing orientation. For clarity, I am referring to images that should be viewed in portrait orientation, but are saved as if they were a landscape image.

I agree. I realized this after I started looking at portrait photos. iTunes is resizing to 640x480 max whereas it makes more sense to instead constrain to 640 so that you would end up with 640x480 or 480x640 max. This could explain some of the fuzziness. If you view a landscape photo with the phone upright or on the side you can zoom a little before you exceed the resolution of the file. If you view a portrait photo with the phone upright then you are already viewing the full size image. This may have made sense for the iPod but it doesn't make much sense for the iPhone since it has the nice rotate and zoom capabilities. I hope Apple addresses this in an iTunes update.
