Camera Correction: In-Render vs. Post?

[Claudio Branch]

I normally use the camera correction modifier within Max, but recently I have also used Perspective in Photoshop. I haven't done any measurable tests, but I got to wondering if both approaches attempt to create verticals the same way.

 

Any ideas?

I would say you're much better doing it in max. Otherwise you are making Photoshop interpolate pixels thereby decreasing accuracy and quality.

If I can (if there are objects that I can obtain mesurements from in the image) I'll do it in max. If not, than I'll approximate it in PS or use a combination of both.

Depending upon the degree of distortion from your lens and view, doing it in Photoshop will force you to crop your image and lose details you might otherwise have wanted to keep. It's same comparison of shooting with a shift lens on a real camera vs doing the correction in PhotoShop. If you can, do it at the camera. In this case the virtual camera.

I know its ideal to do as much as possible in camera. - But doing it in Post does allow a finer degree of control in terms of being able to treat the image non-destructively.

No. Max gives you plenty control via the slider, and I think you need to brush up on the definition of 'non-destructive'.
