 Posted: Wed Apr 11, 2007 8:21 am Post subject: Photoshop and leaning buildings |
    |
|
| I have plenty of experience with automotive photography but I watched a photographer taking photos of a residential interior the other day and he was using PhotoShop to correct the "leaning effect" out of his wide angle shots, making them appear true and square. How is this done and can it be done with just PhotoShop or is there an add-on or another program? I would like to be able to do this. |

If you have Photoshop CS2, it's under Filter>Distort>Lens Correction. You can do it in CS and earlier, but not as easily. There are also third party plug-ins like (I think) DXO (?). Photoshop is still no replacement for a view camera with full swings and tilts as you can do things with the plane of focus with them, but it's still a great tool.

| Thanks Rob. Of course by using a 4x5 and swinging the lens, you are quickly moving to the edge of the glass, losing sharpness, which also causes problems. I'll give you CS2 notes a try. Thanks for the help! |

I'm afraid Photoshop can't fix everything. You're best bet is to take a picture when the weather is less hazy.

i think this is one of the greatest things if you don't use a camera that changes perspective...
for photoshop cs2 (if you have it) i don't think it's on the earlier versions...
In the tool bar go to EDIT>TRANSFORM PATH>PERSPECTIVE.
If you go to FILTERS>LIQUIFY can bloat, or decrease an object, or even a persons size... Same way they do before and afters of people and their phycial apperence. Enjoy! |

to properly correct perspective in Photoshop go to edit/transform/distort
This will give you freedom to pull the building in line from any angle
for slightly distorted photos you will not lose many pixels, but photos that are seriously distorted you will probably loose 1/2 of the pixels due to stretching.
If you have barrel distortion where you can see straight lines being curved at the edge of the photo go to filters/distort/lens correction.
If you have moustache-barrel-distortion from some of the retro focal wide angle lenses go to edit/transform/warp where you can arbitrarely push curved lines straight
Filter/liquify is good for minor adjustment but not for any problems discribed above
good luck
