Photoshop - image rotation problems

Sigma 24-70mm f/2.8 EX DG Macro for Canon

With the 10D and 20D (and doubtless other cameras) you can select "auto rotate" in the camera and it stores which way up the camera was and rotates the photo accordingly on the LCD.

Open the photo in Photoshop and, very cool, PS also knows which was to rotate the photo. Save the photo and it saves it with the correct rotation.... even cooler.

However .....

When you next open the photo in PS it flipping rotates it AGAIN undoing all the good the first rotation did (it now sits at 180 degree rotation).

The above happens with jpg originals, then saved as jpg's again (yes I know, this was a quick/dirth batch conversion on 100 photos). It may well do the same with other image types, I haven't tried.

Anyone know a work around for this?????

Imitially very very impressive .... but now it has just turned into a major pain.

Seems like we are the only ones on the site this (morning for me), or is it the time difference?

Anyway whilst looking for an answer to your question about the autorotate thingy, (which I didn't even realise was there! See I'm learning already),I found this on the web which is really cool I think. No more sloping horizons....
Auto Rotate in PS

Still looking for an answer to your original question by the way.

OK I think I may have an answer.

One way is to save the file in PSD format, if that's not what you want then.......

When you set you camera to Auto-Rotate it senses which way up the shot should be and inserts that info into the EXIF metadata attached to the file when its transfered to the computer.

You can view the metadata of the file in Photoshop, (method may depend on which version you have). There are also Freeware programs which will allow you to view the EXIF data, I can't remember the names of any right now????

In Photoshop CS, probably the simplest way is to view the file(s) in the File Browser window. Files which have the autorotate applied will have a small Rotate icon in their top right corner. If you right click on the thumbnail in Photoshop's File Browser window you will get the option to Apply Rotation. Clicking on that will apply the rotation that is embedded in the EXIF data. That rotation information is then removed and the file will not rotate the next time you load it.

The drawback is, rotating JPG files can result is slight degradation of the file due to the compression algorithms used in the JPG format.

Any good?

Unfortunately, the work around is to not use it. Many of us gave up on auto-rotate because of the numerous problems with it.

Bugger :(

Yeah, I gave up using it with the 10D but thought I'd revisit and try to now get it going. Looks like it's not going to be a go'er.

Thanks for the info there Blackdog ... that looks like it would work, but I guess I was looking for a standard fix that would make it really work without messing around.

What a pain. Adobe have a great idea with doing this one .... but then stuffed it up so it becomes worse than not having it there at all as now you can't even use it in camera without it messing things up later :(

It was soooo good when it looked like it would work as with ONE save everything was the right way up so I didn't need to stuff around rotating every third photo. Oh well, back to the old way.

I see what you mean Natator but, you can still do them all in one step. If you use the PS browser method I described you can select multiple images in the browser window, (using the Ctrl key on a PC) then apply the rotation to them all in one go.

I use the autorotate all the time and have never come across the problem you describe. I've saved in PSD, TIFF and JPEG without any issues. However, I do start with RAW most of the time.

I've only shot a few images in jpeg and don't recall having the problem.

Maybe there's a photoshop setting that causes this.

I'm using PS CS. I don't have the plugin for 7 so was converting in the Canon software, hence no issue. I appologize for any confusion.

Sadly there doesn't seem to be a Photoshop setting. Everytime it opens the file again it goes "oh lookm exif data says camera was on its side, rotate the photo". WHat it should do is place a flag saying the auto-rotate has been done, so don;t do it again.

Hey!

This is great! I was just looking around for a solution to this auto rotate problem, and this PS browser technique (applying rotation for all auto rotated files) works fine as far as i can tell!
