I remember seeing a video tutorial on fixing lens distortion but I don't remember that video is and who did it. how to fix lens distortion in Photoshop CS4? I shot the photo with a widen angel 24mm Nikon lens. The picture looks somehow distorted.
View 4 Replieshow to correct the lens distortion from a wide angle lens that makes buildings lean in as they go up.
I only have PS6,
With any lens, there is an inherent distortion. I've seen grids at photozone.de in their lens reviews. If possible, I want to use Photoshop to create the same distortion my lens would create. For example, if I photograph a sheet of graph paper, the result would be a distorted grid. Can I get photoshop to take an UN-distorted grid, and distort it in the same manner? How complicated is this, if possible?

I'm trying to correct the distortion caused by a wide-angle lens in Premiere CS6. From what I can tell, there is no filter or transform / distort feature within Premiere itself. I followed the steps in this tutorial to open the MPEG4 in Photoshop, apply the lens correction filter, and then export the video again to be re-imported to Premiere. URL....
However this tutorial is for CS5. I am seeing no adjustment or filter layer in my layers panel, as it appears in the tutorial. When I go to export the video, it seems the Adaptive Wide Angle filter or the Lens Correction filter has only applied to a single frame of the whole clip. Bummer.
I need to correct distortion from my 18-200 mm lens for my Nikon D80.
I can experiment with the controls until I get what looks reasonable,but it would be easier if I could find recommendations for settings of the lens distortion filter at different focal lengths for the lens.
I used to use a Panorama Tools plugin for gimp for which I found such recommendations, but I can't get that plugin to work with recent versions of gimp.
Of course I can experiment by photographing a grid at different focal lengths and different subject distances and using trial and error, and create my own tables.
Finally, where can I find a description of the the algorithm that the filter uses. If I had that, it might simplify things. Usually these algorithms apply a polynomial (usually cubic) correction based on the radial distance from the center of the image. The parameters set the coefficients of the polynomial.
There used to be a pnorama tools plugin which allowed one to entercorrections for specific lenses which I was able to find on the web.That worked very well. But I haven't been able to find that plugin forrecent versions of gimp.
There is a lens distortion filter, but you have to use it by trial anderror. I haven't found any specific recommendations to use forspecific lenses anywhere. And in some cases, nothing I try works. Iattach an example below. It was taken, I believe with a Nikon 18-55 mmlens at 18 mm. You will notice that there is no distortion at thesides but significant barrel distortion as you move in from the sides.No combination of major and edge correction that I've tried does anygood.
P.S. I understand that ahd I shot raw with my Nikon, I might havebeen able to do the correction more easily using ufraw. Also, it mightbe possible using hugin to correct the distortion. But I would like tobe able to do it with gimp if I can.
Lens distortion removal folder is missing completely. Perhaps there is a way to download those presets separately?
View 5 Replies View RelatedMy lens profiles in the distortion correction list are small. I looked at the official list and mine is not right. I only have one Tamron lens profile. Nikon and Canon only have about 6 lenses each. What gives?

View 1 Replies View RelatedLightRoom and Camera Raw have profiles for Lens Correction and all the current available lens are in the list for the Canon 6D raw files. BUT the Filter/Lens Correction when in Photoshop CS6 only have 2 Tamron lens listed. Odd that there are lens profiles for the Canon 6D raw files in Lightroom and Camera RAW but not CS6 Filter/Lens Correction.
Camera RAW, LR and PS are up to date..... NOTE: I have a Canon 7D, G11 and 1D Mark II N and all their files work as expected. It's only RAW files created by the Canon 6D.
Why won't the Lens Correction filter recognize my camera and lens, which is shown in the metadata below the correction window? I had been using the venerable Canon 5D Mk II and now the Mk III. For images taken with the III it doesn't even list Canon in the Camera drop down -- too new? Even with the II, I had to choose the camera manually and then choose the lens from a very tedious list, and had no indication if it was using the focal length in the case of a zoom, or the aperture.
I do strongly prefer to do this correction in Camera Raw or Lightroom, and realize it needs to be done on an uncropped image to be accurate. why even present it as an auto correction if it can't use the metadata? Why not just limit it to the manual correction?
I can't find my lens in the Lens Correction menu. Is there a way to add it?
View 2 Replies View RelatedUsing LR 3.5.1. When applying Lens Corrections/Profile/Enable in Default, my Sigma 10-20mm f/4-5.6 actual lens is being corrected by the profile for a Sigma 10-20mm f/3.5 lens. I can tell it's the wrong correction because the barrel distortion after using the default profile is not corrected, and when I manually select the 4-5.6 lens the correction is perfect. So I know the right data is embedded in the LR correction data bank but is not being used.
I found that when I set the profile Setup selector to "Auto" the correct lens is selected and the correction it makes is "correct." But then moving to the next photo it switches to Default again, selecting the wrong lens, and so has to be set to Auto for each photo. This action doesn't seem to me to me an expected result called "Setup." I need this for my home interior photography, and with hundreds of photos a week I don't want to manually operate this. This didn't happen until v.3.4 or 3.5, I think.
So, how do I get it to select the right lens as the Default, or get the Auto setting to stick? Either would do. (Seems to me they logically are the same thing).
In addition, why isn't it possible to have the profile itself enabled as a default perhaps in a preset - or is that possible and I don't know how to do it? In other words, once it's working right, why not make it an import preset for that lens?
I'm trying out the new Sigma 24-105 DG lens with my 5D M II. The lens profile is not yet in the list of Sigma lenses. I checked and my LR is up to date with the latest version 5.3. Is there a way to find the lens profile to import for LR lens correction function? Or do I just need to wait until LR updates for new lenses?

View 3 Replies View RelatedI'm a Sony user and installed the Lightroom 4 trial. It imported the old 3.6 catalog and gave me a nice new Lightroom 4 catalog. So far so good. Everything looked normal.
Now, when I import new .ARW (Sony Raw) pics into LR4, I'm not getting the lens information correctly. I use a tool call 'alphalensinfo' that reads .ARW files and creates .XMP files with the correct lens name. LR3.6 used to import the pics and read the XMP, giving a correct lens name in the LR catalog. LR4 seems to fail at this.
For instance, with my Samyang 8mm, Alphalensinfo would add the exif field to the XMP file saying "Samyang 8mm". LR3.6 then shows "Samyang 8mm" for the lens, after import. LR4 shows "---" for the lens.
Has something changed in the way LR 4 handles Lens EXIF information?
How or where can I get the lens correction profile for the Canon 18-135 STM lens in Lightroom 5 ? In effect he is not available in my list of correction lens so my lightroom is up to date apparently.

two things:
I'm using CS3 on a PC. I'm using the wave filter to distort an image. writing down all the characteristics ie, # of generators, wavelength, amplitude, scale ect. Is there anyway to recreate that EXACT wave pattern on a particular image once I've left the program? It seems to generate another algorithm even if I input the same numbers.
Also, I'm distorting an image at 72dpi as a test. When I replace the image with an exact replica at 300dpi and apply the wave distortion, I'm unable to get even remotely the same results. the wave patterns are much tighter. I've moved around all the characteristics with no result.
How do achieve this effect. I want to create tv distortion, but not in the form of noise. Like when things get stretched, distorted, and look all jagged horizontally. Very similar to when you are losing a video signal.

Any file I open, jpg, psd, pdf, etc. opens with lines and squares all over the image. I can't quite figure out what could be causing this. I thought maybe video card, but it too is current. I have included a picture to display what I mean.
