Hi,

Actually this is not a Photoshop issue...its adjusting the camera and matching similar points in 3D Max....this is done all in 3D Max and has nothing to do with Photoshop....try reading the help of 3D Max and you'll c how u can do this exactly..I've learned it myself from there....

Ciao

Ishpal,

 

i'd suggest that the tension wires have been drawn back in over the top of the composite. if you look closely at the image after comosition you can see the wire change colour in couple of places, as does the top of the street light (again drawn back in).

 

from experience i don't thing it'd be possible to create a selection with that crispness unless the original photo was of extremely high pixel resolution

trust guy i m not asking about camera matching

i m asking about wires

 

thanx jat

i have been trying hard for this type of thing

but never got the hang of it

thanx for helping

sadly you have to carefully redraw the wires, or instead edit a copy of this image and delete everything except the wires and paste in the original with an alpha chanel.

 

look at that image and see that the shadow projection of the sun is not accurately, dont do the same mistake.

Trustguy, I hate to disagree but this is definately a photoshop issue. depending on the rez of the background image, you may be able to select the wires by themselves and create a new layer, most likely though, you'll have to redraw a bunch of it but you can use the original as a template and kindof trace over them in a new layer. Good Luck.

how will u do it with alpha channel in the areas where the wires overlap with trees and buildings

is there any other way out instead of redrawing?

I really din't think there is enough color and or contrast where the wires fade out in the original image at the res posted to pull a mask from a channel, rgb, lab (lightness) or cymk.

 

It looks like the bottom used lines/paths to create the wire. Probably sampled the color from the original image and filled the line or used the path as a mask to paint it.

 

 

My 2 cents....I'd use the path tool

try making a mask for the wires and all other areas of the image.
