Interesting. Thanks for posting.

All these corrections are post capture, and so are pixel manipulations. They are not optical adjustments. So I fear greatly for resultant IQ. For example, from multiple software sharpening as in correction of AA filter, RAW presharpening, sharpening several times in PP as is usual - all of this will come to an ugly end!

My question is does it rewrite the CR2 file of convert it? I also noticed that little tidbit but when he says the .CR2 file will increase in size as a result of the DLO I wonder if it will really rewrite the raw file or if it will convert it to TIFF or some such.

I hope Lightroom is able to mimic this type of functionality. I do not want to run files through DPP and I don't want 3x the file size either. Will test both once I get my hands on it.

Why would RAW files be so ridiculously large with this feature enabled? And is Chuck referring to RAW files coming out of the camera, or re-written RAW files out of DPP? I am hoping it is the later. Would one enable DLO in the camera menu?

DLO, as I understand it, will be a function of DPP (hence it's working with all cameras from the 30D on up).

OK, that helps, and makes sense. My 40D with Canon glass could benefit it seems. But let's say I have a 10MB .CR2 file from my 40D and a 23MB .CR2 from my 5DIII. All I want to do is output a JPEG from (future) DPP from the RAW files I shoot in either camera. My original .CR2's should not change, right? But if I re-save that .CR2 file with DLO settings as a new .CR2 file, that resultant file would become humongous? Is this your understanding?

I was actually planning on emailing Canon to find out if it outputs a new CR2 or a Tiff file, it sounds like a new CR2 but I want to be sure.

I don't know what CW was referring to in the original post when he talked about that function and the Raw files being maybe tripled in size, but it would have to be an in-camera setting. DPP does not save processed .CR2 files in that sense.

I'd say we will have to wait and see as far as how these new processes will work with other cameras -- too little info in that comment to make an educated guess!

I think it is a new version of DPP that would. Either way, it sounds like a big PITA workflow.

Digital Lens Optimization is a function available in the new DPP release.

I guess we'll know in a week or so when someone gets their 5d3 and posts the new version of dpp online.

No, the original RAW file cannot change, it is the full set of data delivered from the camera. Any digital file will "benefit" from pixel manipulation, that's no mystery! And something else that's not a mystery is that when pixel manipulation adds data the file size increases! This will happen on conversion. Thus my gripe, that this kind of thing adds more and more software hoops for the RAW optical information to contort its way through. That does not seem like "progress" to me, at least not in a photographic sense. In a graphic illustration sense, maybe...

Your statement, "the original RAW file cannot change", should be, "the original RAW image data cannot change". DPP already changes CR2 files by inserting new editing instructions into the metadata alongside the instructions from the camera. This is something only DPP can do because the Canon designers know CR2 code, but DPP has always done it. You have the option today in the File menu of Save, which writes the metadata to the original, or Save As, which writes a copy CR2 with the new metadata. However, this adds only a few KB, so the statement that the DLO metadata will be huge is very strange. If the DLO data is in DPP (presumably, a profile for every supported lens/camera combination) why would the file need to contain anything more than a few lines of code saying, in effect, "Do DLO!" My money is on Westphal having made a mistake and meant to say the DPP itself will be bloated by the additional data.

We have just seen a similar occurrence in Lightroom with LR4 being three times the size of LR3 because of new features (book design and GPS).

Yes! That is precisely my meaning!

Thanks for making the clarification!
