Combination of barrel + pin cushion distortion in an old lens...

I have several precious 35mm Kodachrome slides that were shot with an early 80's vintage Nikon 24mm f/2.8 lens, that had a combination of barrel and pin cushion distortion at the same time. In two important shots, the edge of the frame goes away from the center (barrel distortion) and closer to the corners of the frame, the same edge is being pulled in toward the center (pin cushion distortion).
I no longer have access to the lens, and doubtful if it would work on a modern digital body anyway.
Does anyone have any ideas on how to approach starting to create a profile for such a beast?
Thanks,
George

It will be in 6.1, not 6.0.

How do I get rid of distortion when playing old CDs in iTunes?

Yesterday I imported a fairly old CD into iTunes and was disappointed to find playback of the CD was so distorted it was impossible to listen to.
Here are some facts:
All my other music in iTunes still plays perfectly
The CD plays perfectly in QuickTime Player on the same machine from the same drive, so it's not a hardware or CD problem
A newer CD imported today into iTunes imported perfectly
A bit of research on the web suggests it's to do with the fact that the CD was manufactured a long time ago - the date on the disk itself is 1987.
I've upgraded to the latest version of iTunes, removed all iTunes plug-ins from my iMac (as instructed by one of the Apple iTunes troubleshooting pages) and I've also switched off Equalizer, Crossfade, Sound Enhancer and Sound Check, but none of these make any difference.
Does anyone have any other suggestions? Is it something to do with the import settings? If so, can you tell me what they should be set to?
Many thanks

Thanks for your reply. Sorry I wasn't specific about this. I get distortion in iTunes when I play straight from this particular CD and when I import it. With QuickTime, I get no distortion when I play straight from the CD, but (I hadn't tried this before but I just gave it a go) I do get distortion when I play the .m4a file created by iTunes. So presumably it's something iTunes is doing when it processes the .aiff file from the CD.
At the moment the import settings are:
Import using: AAC Encoder
Setting: High Quality (128 kbps)
with the 'Use error correction...' box checked.
I've never had to touch them before. Is there a better setting to use for importing early CDs?
Thanks.

If I'm installing a PC-6221 board to work with Labview 7, do I need to get anything else with it if my connector I have right now is 50 pins to go with my old PC-1200 board?

What other specific things would I need?
Thanks

Hey,
Thanks for the reply. Before I buy the PC-6221 board, a new cable, and a new to go along with it, I was just wondering if there was a way for me to use 50 pins from my PC-1200 board. I have three laying around, so I was wondering if there was a way to use them to make a 68-pin one. This is probably not likely, but any suggestions would be great. Thanks again for the reply, and you understood what I was trying to ask.
Take it easy,
Ryan

Are mid-zoom distortions interpolated in Adobe Lens Profile Creator

Hi!
I'm making LCP files for my two cameras. I use CHDK in my Canon PowerShots for having DNG files. I wonder, if I'm going to use three imaging sets for each camera with different zooms, let us say no-zoom, 1/2maximum, and maximum zoom, does the Lens Profile Creator calculate distortion parameters for the other zoom values as well by interpolating? I think it should do that, but I want to get a confirmation for this before adjusting thousands of photos. I have had hard times by fighting with computers lately, and I can almost sense the "oh-you-did-not-shoot-with-exact-zoom" waiting for me just behind the corner

Tokina 11-16 lens profile-download question

Lens profile downloader_p3_102510.air then clicking on this did not produce any results ....although AdobeAir is on the hard drive ...so I downloaded on 7/12 the AdobeAirInstaller so it might be that my air version is old since its a version 1.## and this download indicates a higher version.
So the only way to download a lens profile is with this downloader ? OR
lensprofile_creator_p3_win_042711.zip Does this have the capacity to view shared lens profiles and download?
Does this downloader go automatically to the storage location and produce a list from which to choose?
The Tokina lens arrived yesterday along with a 7D and I didn't value the lens profile corrections until I had to adjust a wide view of a building, one of the first test shots.
I have to admit I'm a little nervous about the above installs and then searching for the lens profile download . Its likely the AIR feature since in the past I did get errors in the event log connected with AdobeAir.
I guess I'm double checking on routines that others have used.
Rose

I cannot figure out how the download is to begin. I have clicked on Download....the bar fills with a colour and no file arrives on my hard drive.
You need to click on the gold box near the top right of the screen that says 'Upload file.' You will be prompted to create a "free account."
OHho...factory built in tilt....is that so?....I have wondered about that because its just TOO consistent and I have lined up with an object on occassion. Good info to include the tilt into the preset.
Shoot a picture of a window frame that nearly fills the viewfinder and make sure it is perfectly lined up on all four sides. Using a tripod helps. If you see a tilt, then you have the factory assembly defect of a "tilted" viewfinder image. Don't be surprised if it is also a little off-center! My 300D viewfinder is tilted clockwise and to the right slightly. Canon repair may be able to adjust it, but since it was so slight I never bothered.
AND specifics according to the camera serial number... I haven't had to deal with that to date but I have read about it,so its good that the code refers to the camera serial number rather than having to make specific settings.
Please read my correction note – There is no need to do this unless you own two of the same camera model and need to set the defaults differently for each.
I've just used the Jao, Nikon profile on a few Lake Huron sunset shots and a slight correction was made but I still had a tilt ....the lake was running downhill to the north <grin>
You are confusing "rectilinear distortion" such as "barrel" and "pin cushion" distortion with "perspective distortion!" ALL super wide-angle lenses can exhibit significant perspective distortion in different shooting situations, which can be very useful for "creative effects." Vertical perspective distortion is created when the camera is tilted up or down, and Horizontal perspective distortion is created when the camera pointed left or right of a central object. Go into Lightroom Develop module>Lens Correction>'Manual' and move the 'Vertical' and 'Horizontal' adjustments. This applies digital image processing to "correct" your picture, similar to what an expensive tilt-shift lens does on-the-camera
Even when you correct your picture elements for "parallel" vertical and horizontal lines, a super wide-angle lens may still exhibit what appears to be a "distorted perspective." That's both the virtue and deficit of shooting with short focal length lenses – It's up to you to properly apply this creatively to your subjects….but that’s a whole other subject! There are some good tips here by Ken Rockwell:

PS3/Mac Scan plaid fabric swatch and adjust all lines to be perfectly straigh (not wavy)

Hi I am wanting to scan a plaid fabric swatch and adjust so that all lines are perfectly straigh (not wavy).
I know I have learned how to do this in a class, but I cant find my notes, and am desperate, as I have some artwork that needs to be completed.
Any suggestions or advise is Appreciated!
Thanks

Steaming the fabric flat helps immensely. But to keep the pattern components perfectly lined up is not going to be easy. A T-square, triangle or transparent grid overlay is going to be needed. And you may have to lightly tack the fabric down to a base with spray cement.
And then photograph it with a high-quality longer focal length macro lens. Do not use a zoom lens because of barrel or pin cushion distortion. And make sure you have even lighting on the swatch.
Or carefully place the mounted fabric on a scanner. But be careful that the fabric doesn't move when you close the lid. Scan at a high resolution.

How do I apply timestamp and barrel distortion correction together?

Hi guys! My first time posting a question here and I hope to get your sound advice on this editing challenge. At the moment I am using Adobe Premiere Pro CS6 and FastStone Image viewer to do some image and video editing. I am using GoPro Hero 3 HD cam to take photos at certain time interval and then combine then it into a timelapse video. The capture settings are 7mp at medium angle. I know the GoPro take pictures at 12 mp W, but as you know the GoPro is notorious for barrel distortion, so at higher settings, it's even worse.
I am tasked with both correcting barrel distortion and adding timestamp feature on my timelapse videos. I've used the FastStone Image viewer to add time stamp or Premiere CS6 to correction distortion. However, I've been unable to do both at the same time. Now I know that the CS6 has some sort of timecode feature that allows time stamp to be shown, however my time timestamp data needs to be extracted from the original meta data, whereas the timecode feature in CS6 only shows just the total length of the video, not the original date and time when data was captured. Using the FastStone allows me to show a real progression of time on data capture from beginning to end (I am working JPEG images in this case).
Now because FastStone extract the timestamp data from original images and shows them in text label format, when I tried to apply the lens correction on CS6, it would also cause distortion in the text label itself. I've tried the other way too, where I've corrected the barrel distortion in CS6 then imported the images to FastStone, but then I would lose the original metadata (the date and time of capture), FastStone is then forced to work with the modified date and time. Now usually I am working with anywhere from 1000 to 3000 images, and FastStone allows the timestamp to be added in batch conversion. It also has this feature to change time stamp to a desired or specific date and time, however, this cannot be done in a batch, but rather on individual frame or image, and thus isn't very practical when I am working with thousands of images.
So my question is if there's any way I can combine both barrel distortion and timestamp (which is using the capture data)? Thanks guys.

Thanks guys! Turns out it's CS6 is intuitive, I can just combine the two sequences into a single sequence with two different tracks with crop effect superimposed. However, it seems with the distortion correction and crop effect added, I am losing some of the details of original sequence without the distortion correction applied. What tools in CS6 can I use to get some of the clarity and vibrant colors back?

How to Prevent duplicates on Combination of Lookup columns in sharepoint 2010 using infopath 2010 form.

Hi All,
I have list with some Lookup columns like City, Pin, and Text Column Name. All these are required columns.
Now I want to prevent duplicates while submitting InfoPath form if a Combination of City,Pin & Name. (like a Composite primary in Database is used.)
Can some one help me on how to achieve this using InfoPath 2010 Rules, writing rule in Xpath.
Thanks in Advance.

1. Add a secondary data connection to the list where the form will be submitted.
2. Prior to submit via rules, set the query fields in the above connection: City, Pin & Name with values entered in the form. Query the data source and check if the result has values.
3. Show error messages accordingly if exists else continue with Submit.

Does the lens correction profile for the Canon 24-70 eliminate all distortion?

The new Camera Raw seems excellent in the Lens Correction...I will be photographing dancers and will have only 9 feet to work with. I would like to use the widest lens I can with lens correction. The question is whether this new program will flatten out the 24mm lens or if I should use the 35.
Roger Minkow

To add to Eric's great explanation, the corrections here are for barrel and pincushion distortion. That can be present in a lens of any focal length.
What isn't corrected is the effect in wide angle lenses where there is spreading of the image of three dimensional objects away from the center of the field. It happens at any distance, not just close up. It is caused by the extreme angle of projection from the back of the lens to the flat film/sensor plane. Think of a straight on photo of a building that has equal size columns across the facade with a wide angle lens. The columns at either end of the image appear wider than the (same width) columns in the middle. Retrofocus design wide angle lenses help a little bit (the rear of the lens is further from the focal plane than in a standard wide angle), but the distortion is usually there.
There is also distortion from being too close to the subject. Focal length doesn't really matter in that, except that longer lenses don't have the field of view to take in the close subject and can't usually focus that close. So we associate this distortion with wide angle lenses. This sort of distortion would be that where a person's nose in the middle of the frame looks very large and there is quick falloff in size to the eyes, ears, background. I think of this as more an issue of perspective, and this is controlled by camera placement, not by focal length or lens design.

FCP can't detect a new IEEE 1394 4 to 9 pin Firewire

Hello folks,
I am using a Mac Pro which has both 4 to 6 and 4 to 9 pin Firewire terminals. My old 4 to 6 pin cable broke, so I have bought the new Firewire 4 to 9 pins. The camera end is exactly the same, only computer end differs. But when I try to capture the footage, FCP gives me the warning that Capturing device cannot be detected. In fact, Mac can't even detect the camcorder when I wanna use it for Skype. So I am wondering if I need to change some Capture settings, or what the problem might be?
Thanks for any input,
Cheers

Hello,
thanks for your response. I did find out the problem. The problem is actually in camcorder's fire wire terminal. I went to Apple store, tried it on numerous computers, non of them detected it.
Thanks again
Cheers

Anyone else seeing distortion on raw Sony RX100 images again?

This issue has occurred at least twice since the Sony RX100 came out, and has been fixed twice, but now I seem to be experiencing it a THIRD time. Is it just me, or is this happening to anyone else again-again-again?
I'm running the latest Mavericks, the latest iPhoto, and whatever the current version of Camera RAW is as of June 2014. I don't know exactly when this "happened" because I haven't edited much in the past month or two, but what I'm seeing is that my raw images from my RX100 are randomly displaying distorted (as if the lens data is being interpreted incorrectly) either in view mode, editing mode, or both. The thumbnail view is always correct...which is the dead giveaway that something is amiss and the images are in fact showing up "wrong."
If nobody else is seeing this, I'll just make sure my library is safely backed up and wipe my notebook completely and see if I can fix it. However if others are seeing this please chime in so we'll all know we're not crazy and so we can collaborate on getting Apple made well aware that this has somehow broken yet one more time...

It's super frustrating too, because the editing window comes up correctly at first...but after about a second the image stretches out and looks all wonky.
Try, if reprocessing the RAW files will help.
Export one of the distorted files (File > EXport, Kind Originial), and then reimport it.
That should reprocess the original RAW file, using the reinstalled RAW support.
Can you now edit the file? If yes, back up your iPhoto library and try, if rebuilding the library will reprocess all RAW files.

Recording distortion with IDT audio codec

I have 3 DV7s (2x 7250us, 1x 7259us). They all have the IDT codec (6.10.6418.0) installed. Using Windows Sound Recorder, recordings are badly distorted (sounds like old Single Side Band, but worse). I have tried the various versions of the codec and have reinstalled the previously referenced version to no avail. Recording is virtually useless. I have tried 3rd party recording software... useless. I have tried external mikes. Same results.
I need a codec that I can record with.

Hi Curt2020, welcome to the HP Forums. I suspect with multiple notebooks doing the same thing, that it is probably performing properly. I do not know of a CODEC that will improve your recording performance. I have found a few pages with various tips which may help.

Mid to High Range Distortion?

Listening to my iPod in my car on my Alpine head unit, I'm getting distortion in the mid to high range of most tunes, with piano and trumpet getting the worst of it. If it's an older jazz recording, even late 50's (which usually has fairly hi-fi), it's even more pronounced.
I rip my CDs to AAC 192 KB (stereo), VBR, optimized for Velocity Engine, however I notice the same problem on iTMS- purchased music as well. I should add that I've turned off any EQ and SoundCheck on the Pod.
The distortion is less pronounced when playing back on my Mac's Harmon Kardon Soundsticks II, but still in evidence nonetheless.
I'm using the latest iTunes 7, QT, etc. and all my Pods are updated to the latest.

Agreed...I experienced quite a bit of distortion on my old car speakers, particularly with piano music (It was not as noticable with guitar or rock music). Like you, I had no distortion using headphones. I then connected the ipod to my new set of Bose desktop computer speakers. The distortion was reduced considerably. On some songs it was totally eliminated. Although it was still somewhat present on certain piano notes. I experienced zero distortion when playing the same song that on my desktop through my desktop itunes with the Bose speakers.
Hypothesis: Most of the distortion in my case was due to old worn car speakers. Although some distortion is attributable to the iPod itself. Curiously however I do not experience the same distortions when playing CD's in the car.

Can i combine 2 iTunes accounts

Hi my wife and I have 3 kids, we all have iphones now and want to use icloud so we are all on the same page... my question is this... my wife has her itunes account on her pc and i have mine on my mac so is it possible to merge both accounts so we can only have one and then use icloud to make all 5 iphones the same?

You cannot combine accounts.
Just continue to use the old acount with your iPhone (and everything else).
There was no need to create a new account simply because you got an iPhone.
You wouldn't get a new debit card if you go to different grocery store.
