RAW image recording / lens abberation correction

[character_stops]

My question involves which image-recording quality matters when one is planning to use lens correction data. Although one of EOS Utility manuals mentions how Digital Photo Professional can resolve peripheral aberrations, it only mentions chromatic corrections only for images such as those recorded RAW. What precisely are right and wrong recording quality choices, in regard to their correlation to the correction data that software uses to fix aberrations?

"Some cameras, as well as my 60D, will do RAW to JPEG processing in Camera."

Any camera that does RAW+jpg will 'process' a RAW.  So what?  It is no where near what LR or PS (ACR9) or even DPP can do.

No matter what the conversion or correction is, in camera is not the place for it. Is it?

Why would Canon offer correction data for lenses it doesn't sell or make and doesn't even recommend their use?  Maybe I just need some more coffee this morning!

My error; I thought if DPP could download the data it could be uploaded to the camera. I know thats the case for my 1D Mark IV.

No offense Obiwan, but many newbies may not know that.  How many come here for help with 3rd party lens???   I did'nt know when I got into DSLR's.  Many don't know what you know about most stuff even. 

And your statement about the better processing of RAW in post is correct, but for those who may not use post software, it's info for them.

I suppose it varies in different models, I can only speak for my 60D, have'nt checked for all the others.  Depends, if a camera has that option, some do, some don't.  You have a Pro Grade Body.

"...  for those who may not use post software, it's info for them."

Than don't shoot RAW!  That absolutely makes no sense at all.

I read on the Internet a while ago (for what ever veracity you want to apply) that the direct camera to printer (PictBridge) feature and then in-camera RAW processing was driven by the emerging "non-Western" market where immediate access to computers is limited.

One can shoot RAW and also have the ability for limited editing in-camera that could be printed or sent via WiFi.

Thanks John for that info.  I'll surely file it away for future reference

Forgot to say.  My 60D has in Camera Editing of RAW files also.  That's on top of also having RAW + JPEG,  and RAW to JPEG Conversion.

Hey John, you are right my friend.....My Error.  I checked again my Canon Software and discovered that my "Lens Registration Tool", was no longer installed in EOS Utility.  I faintly remember, I may have uninstalled that tool when I 1st installed my software, when I got my 60D....not knowing I would need Lens Registration Tool, later/now.  I just now re-installed my software including EOS Utility and DPP and now have Len's Registration Tool installed.  I downloaded all the Lens data for all my lens and also uploaded them to my 60D Camera, using EOS Utility as you stated.   Sometimes I inadvertantly remove programs and software when I use "System Restore" on my Pc.   Anything installed after I make a "restore point", gets removed if I restore my Pc using...."that restore point." 

Thanks much you're a life saver, had you not said what you did I would have never discovered my error.   And I learned something new about my camera.  Another step on the road to discovery in learning Photography.   I've learned alot here in the last day or so, you guys are a big help, but I always learn here everyday reading the posts.

Thumbs Up my friend

Thanks for the input, man. I understand the difference now - that illumination corrections are in camera no matter what the image quality setting is - that you would have to either shot in RAW or L + RAW for the camera to process the chromatic corrections. Either way, I can see the post-process corrections available, at least in Lightroom, Photoshop and DPP. If I ever uncheck chromatic aberration correction, it will be to avoid decreasing the maximum burst for continuous shots. I just don't understand the point of having check boxes in those editing programs. It seems as long as you wouldn't touch any of the modifiers (sliders, etc.) it wouldn't affect any corrections already made in camera. So why bother unchecking the box for either correction?

You just confirmed what I just found.
