Raw and camera parameters?

Here is a link to 4 test shots.

2323 was shot in raw with WB set for Tungston
2324 was raw WB set to flash ( flash off)
Processed to jpeg with settings as shot.

Whatever WB affects, tags or the image, the WB set on the cam does get applied (AS SHOT)to the image if you don't change it When you convert to jpeg.

2326 was shot raw with parameters set to the far (-) side
processed to jpeg with AUTO parameters off in PSE3

2327 was shot raw with parameters set to the far (+) side
processed to jpeg with AUTO parameters off in PSE3

I don't see any diffference in these pic's. Doesn't look like parameters are applied in any way.

It looks to me that the book is right on WB but wrong on parameters unless there is something I am missing.

By the way I have almost comvinced myself to shoot raw I kinda like the extra control even if it does take more time!!

Tonight our club is shooting christmas lights outside at a 4 acre display. Yep I think I am gonna shoot raw for this one

Thanks for all the input, I am sure others will benefit form this as well as I have.

Yes, you are correct there. If you set the WB to "As Shot", whatever WB you used when you took the picture is what's set for the image that's converted from RAW. But that is done after the fact when you are doing your conversion from RAW to an image you can view on the screen. The WB processing is not done to the image in the RAW file itself but to the image that's derived from the raw image during raw conversion. If two WB test pictures are taken with the same parameters except for the WB being set at opposite ends of the WB adjustment spectrum, both converted images will look exactly alike if you set the WB to the same setting during post processing.

Actually, we can take this a step farther. If you use EVU, FVU or DPP, when you use the default "As Shot" setting for the converion, even the sharpness, contrast and saturation of the converted image will look just like it would in a JPEG file (if RAW+JPEG is selected).

The raw workflow book i've just started reading supports this.

Some things are debateable and some things just is cause they is!

Just for the record, Photoshop RAW converter does not go by what is stored in the file for the most part. It does take white balance into effect as long as you have the As Shot selection selected. Sharpening, Saturation, Shadows, etc. can all be modified and set as your camera default. Just be sure not to mess with exposure or WB or any of those variable adjustments before saving as camera default. Once I found the correct settings for my taste, PS RAW does a great job.

This topic is one of those that never seems to die... some topics are brought up over and over again and get the old response; "do a search." This one comes up again and again, but it always generates conversation. I find that fascinating. RAW is such a mystical concept I guess. ....and I think Canon likes it that way. Canon could easily explain this issue away, and to my knowledge they haven't done so. RAW explainations from Canon never seem to be quite as comprehensive as we'd like. ....just my observations.

Now, a question that I asked probably close to a year ago....I will ask again:
Knowing what we know about Camera RAW, how many of you set your parameters to Adobe RBG and how many select custom parameters. I'm curious.... I'm one of those photographers who switches back & forth between jpg & raw, because I think each have their place in my work. So, this issue of parameters is very interesting to me.

Personally, I find it more beneficial to leave my camera set on Adobe RGB and never mess with setting up other parameters. This way:

1. every file comes into PS as an aRGB file not an sRGB file whether its RAW or jpg.
2. most files require similar sat., contrast, sharpening whether they are raw or not
3. I believe less degradation of the file occurs when processed in PS than in camera.

These 3 reasons lead me to believe that always shooting in Adobe RGB (jpg or raw) is the way to go for anyone who does post processing as opposed to those who pop their card right into a printer at WalMart or something.

Opinions?

...from the PSCS Manual, p.67:

in reference to working with RAW files in PSCS, "A digital camera records the white balance at the time of exposure as a metadata entry. This is read by the Photoshop Camera Raw plugin and set as the initial setting when opening an image in the Camera Raw dialog box."

As already stated above, a Raw image can only be viewed if you give the image viewer instructions on how to interpret it. The Raw file has data attached to it that tells the image viewer how it was shot in the camera so you can view it. This does not alter the Raw data. You can tell the Raw converter to ignore those instructions and pick a whole new set of instructions on how to view the file as to WB, saturation, sharpness, etc. This is not in any way changing the Raw data. Raw is Raw except for a small unquantified amount of sharpening in camera. Canon will not disclose how much.

Jpegs on the other hand do have a permanent set of parameters that can not be discarded but only modified.

Just a side note that in 1D series there is no "base" sharpening at all with RAW. It applies only to consumer models.

Thanks for the clarification. I was thinking of my 10D. I wasn't aware that Canon treated the 1 series differently in this regard.
