I have been reading the thread from that user who is about to be jacked out of a #2 ribbon because the NEF file was modified by his/her picture perfect software.
If planets collide and fate should bestow upon me a ribbon some day in the distant future, I'd sure like to know I'm not going to encounter the same misfortune.
I use Adobe Camera Raw for all my NEF processing. My understanding is that it leaves the file totally unmodified and remembers settings in another way (because it DOES remember the raw settings such a exposure, brightness, WB, etc).
Can anyone with more understanding of this stuff tell me if I will be OK using ACR for my processing? |

| Just edit a working copy of the file and not the one directly from the camera and there shouldnt be any issues. |

Not always pratical.
ACR uses (or has the ability to use) sidecar files for all modifications. So does Bibble, and C1. You want to make sure you're using those sidecar files.
Do yourself a favor and test things out first. Make a test shot, do something, then check the exif on your original to see if the datestamps stay aligned.

My 'Dreams' entry recently was required to be validated. I had made two separate develops of the original RAW file using C 1. The validation was OK, so one would have to surmise that C 1 does not modify the RAW file (pretty much as one would expect). I'm using the Mac version, which seems to write lots of very large 'temporary' files everywhere, so that's probably where all the changes are stored. I'm not using a D70, but I thought I'd contribute while I'm waiting for my dinner.

| I checked RawShooter Essentials, and that doesn't modify the original .nef(raw) file either. Whew! :) |

May not be practical but might be necessary.
What's the big deal about making a copy before you start to do anything to a file, and using that copy as the starting point for all your editing for your challenge entries?
Why are so may people asking about ways to get around this when it is so easy to do?

I don't think anyone's trying to get around anything, just checking whether the software used for the RAW conversion actually changes the EXIF. Why make an extra copy if you don't have to.
Sure, if you shoot enough to fill a CD or DVD each time you shoot or you have plenty of extra disk space then it doesn't really matter.

"Always practical"...
You have what...at most 4 photo challenge submissions at a given time. There is NO REASON you can't maintain the originals of 4 photos. Or just copy them back to the CF card |

You may open ANY raw file in ANY editing application as long as you save the result to a different file, leaving your source file intact. That sounds like common sense to me...

There will never be an answer that will fit all the various photo handling programs. Even if a program does not change EXIF data, some of them record that it has been opened and what program opened it. With this added, technically, it is no longer the original file.
"Why make an extra copy if you don't have to." ???
Simply so that you can feel secure in the fact that you can provide an original if requsted.

From my experience with NEF and ACR is that you CANNOT even save over that RAW file anyway. I have my Prefs set to use a sidecar file too, so that any Camera RAW adjustments are put to that, and not somewhere else on my hard drive. But pretty damn sure that it doesn't put anything in that file as it is.

| If you filecopy the NEF files from the memory then the files will be safe. IF you import either through essentials or picture perfect and wipe the memory card from the D70 after import you are hosed... |
