Sony: Lens Profile Creator knows the subject distance, ACR does not

When making a lens profile for a Sony alpha DSLR, lens profile creator identifies the focus distance, and processes each distance accordingly. However, when loaded in ACR (or PS lens correction filter), the software does not display the distance. Why can LPC read the subject distance and ACR cannot?

function(){return A.apply(null,[this].concat($A(arguments)))}

Is this a complicated way of saying "God only knows"?
In all seriousness, if one program can calculate a piece of info from a file, so could another. The designers may just not have chosen to dig so deeply into the manufacturer-specific data as to do so. Or, as appears to be the case here, the information is derived from known subject material in the image itself.

I have a mid 2009 Macbook Pro and i know the Mini-display port does not support audio out but does it support HDMI out? or do i have to buy a Mini-display to DVI and then a DVI to HDMI adapters?

Run MDP to HDMI for picture. Use a cable like this to run sound from your audio out on your Mac to your TV's audio in. That's about all you can do.

Why would Adobe's Lens Profile Creator distribute the checkboards as JPG files?

Generall, JPG files are a bad idea for images that contain a small number of colors (poor compression) and sharp edges (ringing artifacts). So why then would Adobe distribute the checkboards for Lens Profile Creator as JPG, rather than some more appropriate format such as PNG?

The jpgs are samples of what one might get when one took pictures of the checkerboards. The actual checkerboards are indeed PDFs. It will be interesting to disect the PDFs to see what the graphics are. The really right thing would be vector.

HT5312 this is most worse website that I ever seen . The usefull information are not accesible and more than this the subject of help does not cover all the topics

the page that suppose to help you to change /reset security question does not contain link to change it .
I try using two web browsers and not luck on both .

The option to send reset info, as described on the steps on that page, will only show if you have a rescue email address on your account (which is not the same as an alternate email address).
If you don't have a rescue email address (you won't be able to add one until you can answer 2 of your questions) then you won't get the reset option - you will need to contact iTunes Support or Apple to get the questions reset.
e.g. you can try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management , and then 'Forgotten Apple ID security questions'
or try ringing Apple in your country and ask to talk to the Accounts Security Team : http://support.apple.com/kb/HE57
When they've been reset you can then use those steps to add a rescue email address for potential future use.

I can't login my MacBook Pro, I know the password, but it does not enter. PS: I can't either boot my Mac.

I was with Lion on my MacBook Pro, I came back to Snow Leopard, The firs time I tried to login i fail, but I know my password.
To solve the problem I boot it with the Snow Leopard DVD, but I failed again (I tried many times, pressing C and restarting).

Fannar9,
which model MacBook Pro do you have, which version of OS X is installed on it, and have you enabled FileVault on your internal disk?

Should I bother with the Adobe Lens Profile Creator?

I am concentrating mostly on architectural photography these days and I need a pep talk about the "Adobe Lens Profile Creator". The process seems laborious and error prone - in other words it could end up being a waste of time and money (for the printing of the calibration charts). Has anyone used it to good effect? And with what lenses?
I do the bulk of my work with the 24mm PC-E Nikkor f/3.5 lens and I also use two older lenses - the 28mm PC Nikkor f/3.5 and (my favorite) the 15mm Nikkor f/3.5. All three lenses suffer from a small amount of barrel distortion and chromatic aberration so some correction is usually needed.
I have two specific reservations about the lens profiling process -
1. It came out with Photoshop CS5. Since then the manual controls have increased in sophistication. Can't I get pretty much the same result using the manual adjustments?
2. In my drop-down menu in Adobe Camera Raw CC there are eighty-one lenses listed - but not the three I am using! This is crazy and reflects badly on the people who designed the whole process. Who cares about perspective correction in a 600mm lens?
Anyway, I would appreciate a reply from anyone who has gone through the profiling process. Thanks.

open this lcp with an editor
search any “False” and rename it to “True”
save it and you have a perfect raw - lensprofile
Ok, but what does it mean rename and correct the content of the lcp file?
It remains a profile created from jpg source, CameraRaw could consider it like a raw lens profile but it has no more value than a jpg profile, I believe...
Anyway, for whatelse it could be useful your suggestion to modify lcp file?
Thank you for your attention

Adobe Lens profile Creator

Hello all. I downloaded the Adobe Lens Profile Creator to create a profile for the lens of my camera (canon powershot SX40 HS using CHDK), but I am not able to unzip the zip file program. Updated the winrar and even then it still fails. Can anyone help me? Do any of you have a profile for lenses canon powershot SX40 HS?

How is the best way to capture frame in Lens Profile Creator?

Hello, I read in the Shooting Guide related to Adobe Lens Profile Creator:
When framing the chart in different areas of the image frame, use a combination of physically moving and tilting the camera to achieve an optimal balance for LCP generation.
i. Only moving the camera to frame, so that image plane stays perfectly parallel to the chart, can have an adverse affect on LCP calibration data.
ii. Only tilting the chart may cause depth-of-field issues, where part of the chart may go too far out of focus due to the large angle of the chart in regards to the image plane. This can also have an adverse affect on LCP calibration data
Ok, but I'm not able to understand at all, please help me:
1) is it better if I'll rotate the camera on tripod to left and to right or is it better phisically moving the tripod to left and to right?
2) is it better if I'll tilt up or down the camera on the tripod or it's better picking up or down the tripod bar?
3) if it should be better make a combination of tild and rotate and move the camera how can I know the optimal combination?
I hope that someone who has experimented this could explain me better
Thank you everybody
Damiano

I don't know what is technically optimal, but there is an aspect of practical convenience here, as well.
In my experiments with this, I physically moved the tripod in the left-and-right direction, and then re-aimed the camera vertically as required in order to put the target into the desired part of the frame. I was happy with the results, though I did not make any deep comparative study.
IMO whatever technique permits you to make a sufficient variety of reasonably careful acquisitions, without being unfeasibly difficult, and which the analysis tool does not reject, is probably going to be good enough.

Does the Lens Profile Creator work with Photoshop Elements 8.0..?

Hello,
I am very new to the world of Photoshop, so please forgive if this is an obvious/stupid question...
I am using Photoshop Elements 8.0 and I have a couple of pictures that I need to remove the 'fish eye' lens distortion from around the edges...
The blurb for the Lens Profile Creator says that it is for use in the "Adobe Photoshop® family of products"...
Does this include Photoshop Elements 8.0 or do they really mean it is just for Photoshop CS5, Camera Raw and Photoshop Lightroom...
Any help will be appreciated...
Many Thanks

PSE does not have the user-interface to turn on lens-corrections, nor does the ACR 6.1 update for PSE contain the lens-profile database installer, so if PSE is the only member of the PS-family that you have installed then effectively you cannot apply lens profiles.
If a computer has the lens-profile database installed and lens-distortion-correction has been enabled in the XMP sidecar for a particular image, both requiring PS-CS5's ACR 6.1-updater or LR3 to be installed and one of those used to enable lens-corrections for the image, then PSE can use ACR 6.1 to apply a lens profile, because the version of the ACR 6.1 plug-in for PS and PSE is the same plug-in.
BTW, removing fish-eye distortion completely, which is what enabling lens-corrections does by default, will leave a rather poor looking image that has been completely rectilinearized but has severe stretching of the pixels at the edges, so only the center is useable. With my 8mm Sigma fisheye, I reduce the Distortion part of the correction down to 44 so the black corners are gone, but there is still some bulging of the image.
If you want to experiment with lens-corrections, you could install the 30-day trial of LR3.

'Adobe Lens Profile Creator, SONY-SRF-Files in DNG konvertieren leider nicht möglich'

Hallo
Nach einigen Tagen und vielen Versuchen habe ich nun festgestellt, dass SONY SRF-Files von älteren Kameras, wie z.B DSC-F828 (Sony Raw-Datei) mit keinem der von Adobe angebotenen Programme sauber in benutzbare DNG-Files für den "Adobe Lens Profile Creator" konveriert werden können.
Weder Adobe DNG-Konverter, Lightroom oder Camera RAW sind in der Lage die SRF-Files zu konvertieren.
Deshalb die Fehlermeldung im Adobe Lens Profile Creator: "Detect corners failed because file reading errors occurred"
Damit ich ganz sicher diese Aussage machen kann, habe ich ein Probeset mit meiner Nikon-D90 fotografiert und die Raw-Files der Nikon im Adobe DNG-Konverter in DNG´s konveriert. Danach war es möglich ein neues Objektivprofil im Adobe Lens Profil Creator zu erstellen.
Resume: Entweder taugen die SONY-SRF-Files nichts, oder diese SFR-Files können von Adobe Programmen nicht richtig interpretiert werden.
Vielleicht hat ja jemand noch eine Idee dazu, wie man die SONY-RAW-Files von älteren Cybershots doch noch in brauchbare DNG´s konvertieren kann.
Würde mich wirklich über Angregungen freuen.
Gruß Stefan

DXO Labs Slams Adobe Lens Profile Creator

Pubicly. Check it out here;
Click here

See: DXO Labs Slams Adobes Lens Corrections
This is what I responded the first and second response...
"says Cyrille de La Chesnais, Sales and Marketing Director - Photography at DxO Labs" Uh, ok...so I'm sure HE has an advanced degree IN MARKETING maybe...
The moment that a marketing guy starts talking smack is just about the time to quit listening...
I'm sure that DxO is SEETHING at the prospect that a bunch of users can go out and create profiles of their lenses for free...what does DxO cost?
It should also be noted that DxO is partially subsidized by the French military establishment (as far as I can recall).
Just as soon as Cyrille bothers to go out and actually USE Adobe Lens Profile Creator and can PROVE using acceptable scientific testing that there's an issue, I suggest Cyrille keeps his gums together...
Then...
I've used both...I've created custom lens profiles using the Adobe Lens Profile Creator myself (and the effort, if done well is not inconsequential). I've not yet done a head to head comparison with my profile with DxO with the lens I profiled but I have closely studied the results of the Lens Correction panel in Camera Raw (in particular to write about how to do it in my book) with a variety of lenses and I gotta say, DxO does indeed have something to worry about because the profiles provided by Adobe are very good.
The lens profile I made for a Canon EF50mm F/1.2 lens is very good. I uploaded the profile I made to the Adobe Lens Profile server to share with the community (which suspect is the one thing that really galls DxO the most).
Really, let's hear from DxO's scientists not DxO's marketing guys...and let's hear from somebody who has DONE a profile using Adobe Lens Profile Creator and found severe limitations...
Oh, BTW, the guy mentions keeping the lens profile calibration target really, really flat (to profile the geometric distortion) as though that's some kind of super difficult task. Uh, no, I don't think so...Adobe suggests having the printed targets mounted on foam core and then put the mounted targets in a picture frame to keep it flat. I used a different method of mounting the targets to the front of 1/4 plate glass placed on an easel. That way I could mount multiple sized printed targets up to 36' x 48' in size.
I don't want to underestimate the amount of work involved in creating quality lens profiles. I shot a series of 5 F/stops with 3 focus distances using three different targets. Took about 5-6 hours (the first time) and that's in a studio space that's 26' x 53' with 12' ceilings with professional quality studio strobes and a photographer (me) who has 1/2 a clue what they are doing...I'm sure there will be a range in the quality of profiles for the lenses profiled by the "community". But here's the thing...that's to do lens profiles that can be automatically applied to masses of shots at once via presets or Camera Raw Defaults...but you can STILL go in and fine-tube the results from those profiles and use manual controls not only for distortion, CA and vignetting but also lens perspective correction...not sure you can even do that in DxO.
No, I'm sure DxO is trying to come up with some sort of attack/defense for their product's existence...at the moment, I suspect it sucks to be them, ya know?

I am also having problems trying to install Lens Profile Downloader 1.0.1. I receive the following error message:
This application cannot be installed because this installer has been mis-configured. Please contact the application author for assistance.
I updated to the latest version of Adobe Air, I uninstalled the previous (1.0) version of Lens Profile Downloader (dragged it to the trash and emptied the trash), and I rebooted my Mac. I have tried downloading the file and rebooting my Mac several times and get the same error message every time. Any other suggestions?

Lens profile creator - Best Practises

Forgive me for my ignorance but I am completely new to Lens Profile Creator (and a novice photographer to boot ) and I must confess that I have not read the documentation in great depth, but I am a little confused.
I am a Lightroom 3 user and no lens profiles are availble in LR3 for two of my lenses. So, I took the plunge and have attempted to create the required profiles. The lenses in question are the AF-S Nikkor 16-85mm 1:3.5-5.6G ED and the Sigma 105mm 1:2.8D DG Macro. My camera is a Nikon D300.
The confusion is that documentation is not clear on how many combinations of aperture and focal length (for zoom lenses) is required (or recommended) in a single lens profile. For example, for my Sigma 105 should I shoot nine images at each available aperture (from f2.8 through f32 (i.e. a minimum of 72 images!) or is 9 images at a single aperture enough? If a single aperture is sufficient what should that aperture be?
Whilst I find the procedures to capture the required images straight forward ( if a little tedious) if I have to shoot nine images at each aperture for a zoom lens at minimum, maximum and the mid point of the zoom range, then the number of required images becomes enormous

I have developed five profiles so far and I can help you somewhat. You may also wish to hear from Adobe. The hardest profile that I developed was for my point and shoot, the Nikon Coolpix P6000, which shoots raw images, of .NRW Type, and my profile was for raw images, as are all of the profiles that I have done. I think the lens resolution is very low for that Coolpix camera compared to my other excellent fast Nikons, and the coolpix caused me much problems in my profiles, but I found ways around some of the issues, and had to use less images in some of my sets and I had to use the advanced tab to use less parameters in some cases, and that helped.
You want to vary at least the aperture in your sets. Sets are considered to be images with at least one thing common - such as aperture. So, you could have eight sets of nine images = 72 images, as you said, for your Sigma, if you use each aperture. However, you may also want to vary the distance from the target. Thus if you used two distances for each aperture, 72 x 2 = 144 images.
For your zoom; yes, I did shoot sets at each zoom focal length setting when I recently profiled my Nikon 17-35mm f2.8 lens. I had twenty sets of images with nine images in each set. That equals 180 images for that one lens. And I did not shoot different distances for each focal length. If I had done that, I could have had 360 images of course. I shot images for that lens at f2.8, f8, f11, and f22, and at zoom focal length settings for each aperture, of 17mm, 20mm, 24mm, 28mm, and 35mm.
You can choose to use the same chart or different charts; I used 3 charts for my 17-35 images, size 29x41, 36 points, and I also used chart with huge squares, size 9x13, 108 points, and a third chart of size 27x45, 54 points. *Be sure* to measure the needed square size for each set and change the chart size per what you used in that set and the square size, entered on the right side.
For my other profiles that I have done, I have used a minimum of twelve sets of nine images each, up to twenty sets of nine images each. I always shot mine at the minimum aperture, and at f8, and f11(per Eric's recommendation to use f11), and also at either f16 or f22, whichever I felt I used the most for that lens(nine sets each). I also used the minimum aperture for a given zoom fully zoomed out(my 24-120 at 120 yields f5.6) and zoomed in(the 24-120 at 24mm is at f3.5). And I used at least four focal lengths for my zooms(and I used different distances also for the point and shoot P6000 profile).
Hope this helps you.

Adobe Lens Profile Creator not appending

I am using Adobe Lens Profile Creator v1.04 to make a lens correction file.
Following the instructions, I am trying to append the original file I created with more data from a new Focus Distance.
At Save, there is no option to Append the .lcp file
It worked, briefly, for a few iterations but now Append is no longer an option.
Running on Windows 7 - 64bit
