Some news about the future version of DPP and the 5D Mark III

A further thought that occurs to me is that DLO, like any other lens correction tool or perspective correction (warp) tool is only going to move pixels around - shove some over, pull some out, increase the contrast across a detail's edge. It may interpolate, resample and create new pixels, but it won't double the pixel dimensions. Doubling resolution by resampling would raise a ton of justified protests. There are only three factors that determine the size of a RAW file (or any image file): number of pixels, bit depth and compression. It is very unlikely that DLO will change any of these factors in either a CR2 or a tif/jpg. It must be a mistake or misunderstanding.

If the tool is recording those pixel moves you mention above as instruction steps and embedding those steps in the image data to be repeated upon future reads of the data with compatible tools, then indeed the file size could grow....a lot.

But as far as we know there aren't any other compatible tools, only DPP, and if the profile is in DPP it doesn't need to be embedded. It is almost inconceivable that Canon would open the profile code so that Adobe or other third party converters can utilize it.

When I do a complex edit to a RAW image in LR it adds only about 25 KB to the size of the catalog. Granted QSL databases are extremely compressed, but even if I save it out to an xmp file it is only about 50 KB. Westphal is talking about adding as much as 50 MB, a thousand times more.

May be the process is applied to the raw data itself and rather than modifying the original raw data, the resulted raw data is saved in the .CR2 file as a second set of raw data...???

That's my guess. If it saves a second set of raw data, that's actually good news. It means it'd be trivial to take that corrected set into other software IE lightroom lol.

May be but that means that you have first to create this second set in DPP then switch to LR...

or you culd just do it all in dpp...but it'd be preferable to at least have more options than to have less right?

It's not that simple. What Yves is suggesting is that a new corrected image will be written into the CR2, sitting alongside of the original. How would LR know which one to use? And for that matter, why not overwrite the original? But if DPP will do that it doesn't explain the huge size. Something doesn't make sense, but I guess we will just have to wait.

Yeah, i'm sure it wouldn't know right off the bat, but it could be programmed in I'm sure...I dunno, we'll see how it operates. might just be a flag . I'd also like to know what lenses are supported, eh!

The manual is out. Perhaps an answer lies within?

Interestingly, the 5D3 manual covers lens corrections, peripheral light fall-off and CA correction during either automatic jpg generation or controlled RAW conversion, but makes no mention of DLO or of any change in CR2 size. So apparently DLO will be done in DPP only.

Somebody said DLO is Canon's reaction to the D800E, so maybe this is a late development that they didn't have time to put into the firmware. Or maybe they just didn't think it would be a good idea to clog up your memory card with those 80 MB files.

People are startin' to get 'em so we shuld know today i think...yay

If that's the case, wouldn't that mean the new version of DPP should be available for download or be uploaded soon? Anybody see it on one of their sites?

In the past it was about two weeks to a month from the time the cameras hit the stores until Canon officially posted the new DPP, but sometimes there were people that made it available before that, especially one guy in Japan who I think was either a Canon employee sneaking it out or connected to a photo shop where he had access to the disc

It sometimes takes a little bit for it to be posted. Week or two. If it's not on the Canon USA site check China or EU. =p
