AFAIK PTLens doesn't do CA correction during raw conversion, which is
not optimal. However, I wonder whether my Samyang is different, since it
doesn't show visible CA...

If you have a high bright dark contrast sharply defined in any corner you don't
see any CA? That would be pretty amazing and you should hang on to that lens.

Maybe what you are referring to is the purple fringe?  That's different.

Well, no. I see the usual purple fringing but no CA. How to distinguish

Ooops, sorry. I looked at the TIFs and for some reason DPP didn't copy
the Makernotes lens type over so I didn't recognize they where already
corrected and the RAWs where stored away on an external drive. In fact
the Samyang 8mm images show a clear purple-green fringing which can be
corrected well with DPP.

I used the EF 50/1.4 as fake lens, left the main slider at 100 and
pulled both R and B sliders to the very right.

I tried PTlens in PSE, but I prefer the DPP raw correction. I like doing my raw
processing in DPP and then exporting sets as a batch, which I can't do in
PSE/ACR. ACR also ignores any processing I did on the raw in DPP so I would
loose all I do in DPP if I want to use ACR.

Also PTlens costs money for something I think I should already have access to.

There was an earlier thread that had stated the exif editing trick was no longer
working after DPP ver 3.10.x. Is it possible to keep an old version of DPP
installed along with the current version? (Win7 64bit) The Canon install update
the existing version so the old version is no longer there.

I have tried the exif editing trick with exiftoolGUI outlined by posts in
various places, but so far the lens correction still remains unavailable. There
must be a way around this if we can just find it.

Anyone have a short length Canon lens that works you could post a raw sample of
so I could copy the exif?

Thanks.

A little more info on the subject:
The trouble with the latest versions of DPP with regard to 'fixing' the EXIF
from non-Canon lenses is that besides the regular FocalLength field it now ALSO
checks the recorded ShortFocal and LongFocal fields.

To change these you could use a recent version of ExifToolGUI which has a new
option to "modify ShortFocal & LongFocal according to LensType" in the
'MakersNotes Canon' menu. Select that option.

Note that you can also change the reported FocalLength in the Quick-menu. This
means that you can modify your EXIF to *any* lens type you want, no matter what
the original was. Just make sure you change the Quick-menu FocalLength to a
value that is appropriate for the lens type you selected in the MakersNotes
menu.

I always use the EF14mm f/2.8L type for my SIGMA 15mm f/2.8 Fisheye RAW images,
as the two are not too dissimilar. Sadly Canon's own 15mm Fisheye is not in the
list.

If you'd like more info about ExifTool and ExifToolGUI you should have a look
here:
<http://u88.n24.queensu.ca/exiftool/forum/index.php#c1>

The latest version of ExifTool can be found here:
<http://owl.phy.queensu.ca/~phil/exiftool/>

The latest version of ExifToolGUI can be found here:
<http://u88.n24.queensu.ca/~bogdan/exiftoolgui421.zip>

Success!

I know, I know, but apparently these lenses still haven't yet been added to the
list of lens types in the Canon Makersnotes menu in ExifTool.exe : (
Hopefully they will be included in the next update.

You can do it manually. In ExifToolGUI select your images, use the
"ExifTool direct" switch and enter:
-n -L -v0 -Canon:LensType=13
or if you don't want to create a backup copy:
-n -L -v0 -overwrite_original -Canon:LensType=13
as a command line.

This will set the EF 15/2.8 fisheye. See
> http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/Canon.html#LensType
(or http://tinyurl.com/6g3hox5 ) for a list of lens type values. Make
sure the underlying exiftool.exe is the most recent version.

I didn't try direct mode before, but that command works and it's easy to do.
Thanks for sorting that out Erik!

Now I still need to find out how to set the ShortFocal and LongFocal Tags
manually. With the 5D (old type) + the SIGMA 15mm, ShortFocal is set to 24mm,
not 15. With the 5D MkII and the same lens they both are 15mm, so they should be
fine. I'll see if DPP accepts the modified RAW files in a minute.

In the list of CameraInfo tags for the EOS 5D, ShortFocal and LongFocal are
indexed 147 and 149 resp., for the MkII they are 232 and 234, but I don't know
yet how to set the correct values in manual mode.

Ah, easy!
Just had to add the ShortFocal tag with an appropriate numeric value to the
string, so it reads like this:

-n -L -v0 -Canon:LensType=13 -Canon:ShortFocal=15

and DPP now also lets me access the 'Lens aberration correction' menu for my 5D
+ 15mm SIGMA Fisheye RAW files using initial settings that should fit my lens
very well, excellent!

Cheers!

The focus distance set in DPP's 'Lens aberration correction' has a significant
influence on the effect of the settings for de-vignetting and CA removal, but
even if you apply a recipe file containing values for these corrections, the
shooting distance still needs to be set manually for each individual RAW file or
it will always be at infinity. This is not very convenient if you want to
process a larger number of images in one go.

I tried the parameters listed below in the command line for ExifTool/ExifToolGUI
to see if they had an effect on those corrections, but alas they did not.
-Canon:FocusRange="5"
-Canon:FocusDistanceUpper="3"
-Canon:FocusDistanceLower="1"
These change the EXIF as intended, but apparently these are not the ones needed
for the lens aberration correction in DPP.

Does anyone know how to set the focus distance in Canon RAW EXIF to make this
work?

OK, thanks for all the advice.

I did this:

-n -L -Canon:LensType=490 set to canon EF 8-15mm f/4L USM

-n -L -Canon:LongFocal=15 max zoom

-n -L -Canon:ShortFocal=8 min zoom

-n -L -Canon:LensModel=Samyang8mm

-n -L -Canon:FocusDistanceUpper=3

-n -L -Canon:FocusDistanceLower=1

-n -L -Canon:FNumber=8

-n -L -Canon:FocusRange=10

-n -L -Canon:TargetAperture=8

Many of these probably have no effect and the ones that do probably could be
further optimized but it does work for my Samyang 8mm.

In the lens correction screen any peripheral illumination is very bad so turn it
off.

For CA, slide the bar to '0', then tweak the R/B sliders for best results. A
single position does not give the best results everywhere in the image so some
compromise is made. Mine are both just under the furthest right positions.

Thanks, and if anyone can offer more optimized settings for the Samyang 8mm I'd
like to hear it.

BTW the -vo option just gives me an superfluous or invalid option error so I

Hi David,

That -vo parameter should be -v0 [minus vee zero].

Also you do not have to feed ExifTool/ExifToolGUI a series of individual
commands, you can cluster them in one single string.

Such a string of commands could in your case be like this:

-n -L -v0 -Canon:LensType="490" -Canon:FocalType="2" -Canon:LongFocal="15"
-Canon:ShortFocal="8" -Canon:FocalLength="8" -LensModel="Samyang 8mm Fisheye"
-FocalLength="8mm"

There is a limit to how many characters such a string can be, but you can make
it quite long. Just make sure you separate commands by spaces, and, for good
form, put the actual values between "".

Also you can save and re-use your command strings in ExifToolGui in the 'Edit
Predefined' sub-menu of the 'Exif direct' menu.
The interface for doing this is a but clumsy, but it does work.

Cheers!

Oops, made a mistake:

-FocalLength="8mm"

should be

-FocalLength="8"

Sorry 'bout that.

Remember this thread?

With newer versions of DPP I can't get this to work anymore.

I tried copying the exif from an EF 8-15mm Canon lens, but it was shot on a
different camera (5D Mk II) and when I open the edit page the DPP module
crashes.

Maybe if I had a sample raw from the EF 8-15mm shot with a 50D I would have
better luck.

Or has anyone figured out the proper exif tags to set to get lens correction to
work for recent versions of DPP?

Thanks.

A single position does not give the best results everywhere in the image so some
compromise is made. Mine are both just under the furthest right positions.

I'm curently using DPP's lens correction with images taken with Canon 350D and
Sigma 8mm 3.5
it works even with latest DPP 3.11.4.10 (I have now)
The exif need to be patched.
Please send me an original RAW from your camera shot with the non-Canon lens and
I'll send you back the proper script for patching, if you using Windows.

cheers,
Dorin

Just downloaded and checked and works with DPP 3.11.31.10
I think this is the very recent DPP available.

That would be great!.  I've tried for the last hour to construct one myself but
found I couldn't do what I wanted in exiftool.

Here is my sample image:
http://dl.dropbox.com/u/22539541/_MG_0253.CR2

What is your method to modify a large set of images at once? Or do you have to
do them one at a time?

Thanks,
David B

I patch several hundreds images  at once, well, about half of a second for each
on my slow computer.

Here is the patched RAW

http://dl.dropbox.com/u/50822921/David/_MG_0253_patched.CR2
please check and tweak the CA correction further more if you want, you can use
then the recipe to the RAWs patched with the follow script
and here is the script
http://dl.dropbox.com/u/50822921/David/10-22.bat
you will also need the exiftool.exe I can upload it as well but being an exe I
think you better download it from the publisher.

In a folder put the 10-22.bat file and the exiftool.exe file
copy all the RAWs in that folder as well then launch the 10-22.bat All the RAWS
will be patched and you can paste the recipe to all in DPP, this also can be
scripted.

cheers,
Dorin

Thanks, that sure works on the CA in that image. I'll have to try a few with
bad PF.

Do you think there would be any advantage to using the EF 8-15mm (lens type=490)
vs. the 10-22mm lens as the Canon 'host' lens? I tried playing with that a bit
but it didn't seem to make a difference.

As you say, it will be needed to try to see, it took me almost an year to end
with 10-22mm for my Sigma, previous I used other lens with not so good results.

As my Sigma is fixed at 8mm, your job will be more difficult for the 8-15 mm
range.
I'm planning tu use 8-15mm at sometime in the future but the trouble is I'll
need two as I'm doing stereos an the cash not allow it now :(

But once I'll have them I'll test more and I'll let you know.

Sure worth trying changing if the 10-22 doesn't look good enough.
BTW PF may need separate fixing approach.
As the CA correction is almost sucessfuly all the time, for the PF the color
blur from DPP migh not be so effective, extra addressing in PP migth be
required.

Good luck
Dorin

Sorry that I have to add this.
My previous messge might look as non-sense without this info.
Even if I'll use the 8-15mm from Canon the RAWs from my Canon 350D camera still
need to be patched as my cameras doesn't record some of the lens info in exif.
Wether I'll patch as 8-15mm or 10-22mm is yet to be seen.

cheers,
Dorin

I don't have the EF 8-15 (I'd like to have one someday though), just thought it
might be closer to the 8mm Samyang. I tried it and the correction didn't behave
any differently than the 10-22.

It does work better on the PF that the PTlens plugin I tried.

I suppose I am happy with the results of this fix so far. It's a definite
improvement in my Samyang 8mm images.

For stereos I just use the cha-cha method. I'm still learning to get the
geometry correct based on distance from the subject, but I don't expect to go so
far as using two cameras and lenses.

Then is easier, I had the impression that you use  a non-Canon fish-eye zoom
lens like Tokina 10-17mm, that way I said that will be difficult for you than my
fixed 8mm, but now I read again and saw that was about Samyang.

The 10-22 patch then might be enough.

cheers,
Dorin

Yess, found it!

For pre-setting the 'Shooting distance information' in Canon DPP's 'Lens
aberration correction' menu add this command to your ExifTool direct string:

-AberrationCorrectionDistance="value"

Example:

-AberrationCorrectionDistance="0.5"

This value (0,5) will set the focus distance parameter for the lens corrections
to the middle of the slider. Default value is 1 (one), and sets the slider to
infinity. 0 (zero) will move the slider all the way to the left, at the closest
possible distance.

Cheers!

Turns out that, as far as I can see, this Shooting Distance parameter can only
be *modified*, not created in ExifTool. This means that the RAW files must first
be processed in Canon's DPP, so the complete set of CanonVRD tags is added to
the EXIF of those RAW files.
How inconvenient for processing pano series : (
