Perspective
« on: September 17, 2004, 05:03:11 PM »

[font color=\'#000000\']I see no ethical problem here as long as the intent isn't to mislead the viewer.  Because the camera causes the lean, straigtening can restore the original view and be less deceptive that the original.

This effect can be achieved in-camera with some tilt or rise.  I use it freauently for buildings to make them look more like the original building.  Why more photographers don't use it I don't know.[/font]

[font color=\'#000000\']In Art, as opposed to Life, there is virtually no penalty for constructing one's own system of ethics.  Do what works for you; take the advice of others with a block of salt.[/font]

[font color=\'#000000\']rickster, I don't have a link, but it is pretty simple.  Go to Edit, then to Transform, then Perspective.  Grab an upper corner and move it in or out, and the other corner moves as well.  The image changes perspective.  Skew works in a similar manner, but one corner at a time.  When done, go to the Crop tool, and click Apply.

If Transform isn't available, make a duplicate layer and try again.[/font]

If Transform isn't available, do a Select All <Ctrl A>, to make it come out.

Perspective transformation can also be made with a crop.

Yet another way to do it is to use the Distort transform instead of Perspective. Distort offers additional adjustments that can be handy if the camera was not level or if the desired correction is of an object at an oblique angle to the camera....

Any of the transform options can also be used to exaggerate and distort as well, though these are outside the scope of my question on ethics: about making perspective corrections in landscape photos of natural objects, not buildings.[/font]

[font color=\'#000000\']Perspective correction has been available for years in Photoshop and most other digital image software. I use it frequently, not just to fix leaning buildings but also to straighten converging trees (except when the convergence is part of the art) and even on mountains and valleys if I know the camera was tilted upward or downward when a photo was taken. My question is whether you (all) consider perspective correction to be ethically acceptable in these circumstances and, if so, why more photographers don't use it?[/font]

[font color=\'#000000\']The "leaning building" look is an artifact of the photographic process, so I see no reason not to use perspective correction to make the print more closely match the original scene. I've found vertical perspective adjustments to be useful on portraits to decrease the size of the waistline in relation to the head and shoulders. As to why many people don't use this technique, who knows? Many people don't know that the technique exists, and others probably don't want to pay extra for the tools to do it. YMMV.[/font]

[font color=\'#000000\']I'd like to know more about this feature. Can anyone post a short summary on its proper application.[/font]

[font color=\'#000000\']Thanks, Howard.
That was enough to get me started. I never knew that capability was there.[/font]
