Photoshop "Tilt/Shift Lens"

[jarrydbekker]

I heard once of perspective correction done in photoshop. Aparrently

this gives a almost identical effect as a T/S Lens. Does anyone know

how to do this? Thanx!

In Photoshop. Go to Edit > Transform > Perspective. You will

have several handles to manipulate your image.

Here's a sample of Perspective edit in PS. Top is original,

bottom image has been shifted in PS.<div></div>

I use photoshop all the time to correct my perspectives.

 

The only downfall of this technique is the cropping of the image.

Depending on the amount of correction, you might loose

something vital. Shoot wider than you need so you won't cut of

anything vital when you crop your fixed image.

 

You can see the crop from the above image, it has lost about an

eighth of an inch on both sides.

 

Hope this helps

Another trick for emulating a shift lens is stitching.

 

I have a number of pictures made by taking two or more shots--tilting the camera vertically between shots--and then stitching them in Panotools**. In the process of stitching, the perspective correction automatic. In this particular SW you have a lot of parameters that you can tweak--eg the reference point (the point where you eye would be looking straight on.

 

The nice thing about Panotools is the unlimited ability to stitch both horizontally and vertically--with no need to control camera tilt.

**I actually use PTAssembler, a GUI front end for Panotools developed by Max Lyons. He provides the whole package: www.tawbaware.com

You don't even have to do Edit>Transform>Perspective - just do a crop with

Perspective checked.

You can emulate shift, but you can't emulate tilt.

"perspective correction's" in photoshop warp and remap the the pixels; which can drop the sharpness in critical applications. Whith small corrections; the "loss" is usually not noticeable. Wih massive correcttions; the loss is noticeable.<BR><BR>With a view camera; the movements can be used to eliminate a lightpole from a building.
