Rotation in Photoshop CS - DPChallenge Forums

I have just been out and shot 200 odd pics of some motocross, mostly just playing around and learning the camera. Came back to do my usual delete of 50% or so as an initial cut down. Part of that process is I rotate all the pics so they are the right way up.

The 10D, with the setting on, auto rotates images on the LCD so they are the right way up, very useful (and you can disable if you don't like it.

I've just noticed that Photoshop CS (I do not believe it was in 7) can read this data and all images I've taken are being open in CS the right way up. Simply save and there you go, no need to manually (or in batch) rotate now.

I am not consistent with the way I hold the camera when shoting on the side, so this saves me additional time as a traditional batch rotation of shots has to go all CW or CCW so I end up having to do 2 batches.

Correction ...

This may actually be a majot pain in the butt.

It rotates correctly when you first open the pic, thank you very much.

You save the pic again, now the right way up.

You open it again and ..... pic data says rotate 90 degrees, so it does. You now have your photo on its side in PS but the right way up in anything else.

I'm not exactly sure what is happening here, but they have definately not done the magic I thought they had. If it keeps behaving this way it is a major pain and I'll probably end up turning off the in camera rotation and see if that helps.

PS 7 does indeed read the file and automatically rotates the image in both the file browser and when opened. However, when you open the image and try to close it without saving it always asks you to save your changes. Highly annoying. I no longer use the auto rotate because of that "feature" in PS 7 and the fact that it rotates the image on the 10D's LCD as well. After all the LCD is small enough already without making the image any smaller by trying to fit the long side of the image on the short side of the screen.

Yup, I've turned it off as well.

Nice theory, doesn't work in practice.

I love the orientation sensor. It is actually one of my favorite features and saves me all the time of manually determining which photos need to be rotated -- especially since I'm shooting in portrait orientation more and more. I shoot in RAW and "develop" my TIFFs/JPEGs with C1 LE. C1 obviously handles the orientation data and in general just makes my whole digital workflow so much better... I don't know what I'd do without it!

I love the idea Eddy, when I found it I thought "great!".

The trouble I was running into with Photoshop CS is that it seemed to get itself screwed up with reality.

For instance:

Photo in camera: Rotated to be the right way up.

Photo on PC in a viewer (ACDSee) is sideways, as you'd expect.

Open in PS CS, Auto rotates to right way up, great! Save.

In viewer, right way up, great!

Open again in PS CS ... photo is NOW on its side. Huh? Still looks good in ACDSee.

I didn't quite work out what was happening. At one point I had a photo entirely upside down, but I don't recall if that was in the viewer or PS.

This was all shooting .jpg format as it was for a kid's party, but it was annoying enough that I've turned off the "feature" until I can sort out what is happening. I intend to investigate further at the weekend.

Try holding it at 45 degrees.

I just tried that one General and my monitor toppled off the desk, thank you!

Oh, you meant the camera!

LOL -- don't hurt your back getting it up on the desk again!

Seriously, my tripod has an adjustment to rotate the camera to portrait orientation, with degrees marked on it. I just wonder at exactly what point does the camera rotate the image, and would it freeze up* at exactly 45 degrees.

*See, I was just trying to ruin your camera; the monitor's a "bonus."
