I've also sent a ticket on this, but in case anyone has better luck than I in finding the answer in a forum thread ...

Is it legal in basic editing to use Photoshop's filter that corrected lens distortion?

I could swear I saw a thread where this was deemed legal, even though the usual transform tools were illegal.

I'm not asking for whether they should or shouldn't be legal, or guesses, but specifically whether anyone remembers that conversation or can find the thread.

Like I said, I've also sent a ticket to the SC, but in case they're all offline today for Christmas, finding that thread could also help me before tonight's rollover.

Thanks!

Thanks, Judi! That thread was much more recent than what I remembered, but I heard back from Kirbic with the same conclusion: not legal in basic editing.

You may rotate. You may not use any distortion tool, like transform options or the lens correction filter.

Correcting the horizon is easy to do while complying with basic. You use the ruler tool - lumped in with the eyedropper tool - to draw a line along the bit you want to be straight - the longer the better. Then go to Image > Rotate Canvas > Arbitrary and it already has the degrees and direction set for you.

Nah. Rotating affects everything the same. Distorting means stretching in selective ways.

well thats what i am saying, in cs2/lens correction there is a toll that lets you draw a line on the horizon or any other area you want and it rotates to that line

To be safe, I use this method.
