Hi Guys, I'm a newbie to this stuff,I am going overseas next year,a lot of time will be photographing the beautiful colorful buildings around Moscow. I can't afford a tilt shift lens and would like to know if lightrooms 4 lens correction will help,also what I should do regards lenses, Should I use a wide angle or tele lens. Thanks in anticipation, Mal.
Lightroom's lens correction corrects for lens distortions like pincushioning, vignetting (light fall off), and barrel distortion. The predominant issue you will be facing shooting tall buildings is keystoning which is created when you tilt the camera upwards to include the tops of the structures. This causes the vertical lines of the subject in the image to converge. In order to correct this in post processing you have to use something like Photoshop's Transform tools. There are several choices in this tool such as Perspective Correction to help mitigate this problem. A tilt/shift lens allows you to raise the lens upward while keeping the camera film plane perpendicular to the ground, thus eliminating the keystone distortion.
As far as choosing between a wide angle and a telephoto lens for architecture both have their uses. The wide angle would be used to photograph a building in its entirety while a moderate telephoto would be a good choice to single out interesting architectural elements of the buildings.
LR 3.6 also has the vertical adjustment, which works quite well. A couple of caveats - you may end up with a significant crop, and, you will need to ensure you have enough "dead" space around the targetted areas so that you can do the crop, otherwise you may lose important details in your image. I have used the tool successfully but usually forget my two caveats noted above!
I'm not wrong Kari. Did I say that Lightroom DID NOT have this correction feature? I specifically avoided mentioning what capabilities LR has because I do not use the program to this extent. I said that one would need to use a tool SUCH AS the one in Photoshop. But thanks for the additional info anyway.
sorry for misintepreting you but you did list some other features which, unless I had known about keystoning in LR, would have made me assume that it doesn't exist. Anyway, I didn't know about it myself, until I watched a Lightroom video tutorial a 3-4 months ago. Perhaps it's well hidden or maybe I just haven't had enough need for it.
