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?

how to correct the lens distortion from a wide angle lens that makes buildings lean in as they go up.
I only have PS6,
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 Replies View RelatedI am facing problems while 'stitching' the panoramic photos that i shot. basically, Photoshop's File>Automate>Photomerge and Edit>Auto Align/Blend Layers works good, but FAIL on the LENS DISTORTION.
i had tried to correct it with Filter>Lens Correction, but still not getting perfect result. see the attached image for the results, were you can see the building looks bent. check/download the source images from [URL]......
Lens correction, and therefore vingette does not apper in my distort filter drop down menu in cs5? can I put this in to this filter or is it somewhere else.

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?

I am using a Collegiate style font and then rasterising the text to allow different coloured parts and blending the letters in to each other. I have produced the image in small scale, but now need to redo the image suitable for printing at such a large size. I know I will have to start again from scratch but am concerned that it may be pixelated at such a large size.
View 4 Replies View Related, I have CS5, and a Sigma 15 - 50 lens.
If I want to apply lens correction in ACR thgere is a dropdown list of lenses, but my lens isn't included. presumably because it has been superceded by the 12 - 24.
So, is it possible to create a custom profile for this lens and save it for future use? if so how do I do this?

My selection set consists of dbpoints that exists on my drawing and they are more or less in line
I create a new point3dcollection with this db points
I want to create a 3d polyline based on this point3d collection
My problem is : how to sort this point3d collection based on a picked start point and picked end point?
The only idea I have is:
from start point i calculate the distance to each point3d from collection and based on the results i sort the point3d collection based on distances.
My vision is when someone inserts "block A", a promt will come up and ask "how many of "block A" do you need?" Based on how many you need, it will insert the block along with the arrayed amount the user has typed in.

LightRoom 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.
I am currently working on making a lens profile and the instructions are pretty annoying as they require the calibration chart to remain in the same spot while you tilt the camera as well as move the camera around to make sure that you are tilting the camera to bring the calibration chart close to a side of the frame but not clipping it and also staying within an angle of 10-30 degrees.
This seems overcomplicated, instead, why cant adobe make a single calibration grid where the camera is positioned in such a way that it fills the entire frame as much as possible without clipping, then it simply corrects using the single chart.
With the way it is now, unless you have the camera on a computer controlled dolly and computer controlled head, you will not be able to make a completely accurate lens profile.
how to create a selection set based on a specific Multileader style? I can currently creating a typedvalue array to define the filter criteria, but cannot find the DXFCODE for the Multileader style.

I am doing some animations involving sine waves, and I can make an expression that controls the translation of an object such that it travels along the path of a sine wave, but I can't figure out how to dynamically create an editable sine wave curve.
Is there a way to have Maya generate a curve based upon the path that an object travels upon?
For instance I have a sphere that is moving along the X axis with time, and also moving up and down on the Z axis back and forth. I would like to make an editable curve object of this path of motion.
I can see in Maya 2012 we will have motion trails where we can see the actual path an object is moving along, and that we will be able to interact with this path to alter the animation, but what if we could take that path and make it an actual curve or NURBS object?
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?
