Unfortunately the photographer did not correct for the lens distortion that a wide angle lens can create. I would like to use raw to preserve dynamic range. What happened here is that the photographer used a wide angle lens to capture more of the room than most listing agents get with their point-and-shoot cameras. If I export a jpg or tiff from lightroom (with lightroom lens correction applied) there is no vignetting. I even tried to export and overwrite the existing files when exporting the corrected LR selections to the folder that had the originally imported files in Picasa but it didn't work. I have a dmc-fz2500 panasonic camera, and when I export a wide angle shot from lightroom as a raw, I get heavy vignetting at the edge of the photo. In some cases, like with a wide angle or fisheye lens, the distortion is quite obvious. Usually, the distortion is slight and not apparent in a casual view of the image. Cameras and lenses have intrinsic distortion. I have been experimenting with some basic PP using the Pentax DCU 4 to see how I can improve upon the JPGs created with by the camera.
#Can picasa correct camera lens distortion how to
I thought that regardless of where I instructed LR to deposit the corrected images in whatever directory via the pre-set that this would be do-able and that I would not have to do an extra step of "exporting" the corrected images from LR back to the Picasa folder. In this post, we take a look at 2 types of distortion and how to correct for them. What I have to do is select all of the LR images and export them to the directory in Picasa to have the exposure correction copied over which is an extra step and a duplication of photos.
However, when I look at the photos that were imported into the Picasa folder the correction does not seem to be done. The images in the LR are viewable with the exposure correction working. Meanwhile its very hard to judge by eye what 'looks. PST: As Michael Reichman observed on the Luminous Landscape site, Canons S90 is a member of a newer breed of camera that corrects lens distortion on its own, making parallel. The import works and creates the folder in Picasa as a subfolder with the date and in my preview. Can anyone recommend a website that lists the amount to correct for distortion in PSs Lens Correction filter for a range of Nikon lenses at different focal lengths Ken Rockwell gives amounts for a few lenses, but doesnt explain how he calculates them, so Im not sure how reliable they are. I'm trying to use an exposure (and more) correction pre-set on photos that I am importing from my camera into a folder in Picasa using LR naming the subfolder in a date forma.
