Your answer to this question, while technically accurate, is a bit misleading at best.
Shutter speed, aperture and ISO are the only settings that directly affect the actual image data stored in the RAW file. Exposure compensation will also affect it in that Exposure compensation causes the camera to adjust one or more of the above.
Settings such as white balance, contrast and sharpening are not used to alter the image data at capture-time, but instead are stored as meta-data in the RAW file. This information is used as the default editing/display settings, but since the "as-seen-by-the-sensor" image data is recorded regardless of these settings, they can be completely thrown out and/or readjusted at the time of editing.
To answer the original poster's question, these settings do affect the default display and printing of a RAW file, but not the underlying image data. As such, they can be completely readjusted at import time.

That is exactly what I meant. You just sum it up better. The part about reajusting is you can't always easily throw out the extra settings to get back to the original. If you want a file to apear on your computer as close to the way the raw file was recorded then it is best to shoot in Adobe RGB to begin with.

So I think the answer was something around what I said a day ago ... see, just listen to me and don't argue! ;-)

I'm pretty sure that no in camera sharpening is used when shooting raw. |

Part of what you said. I'm pretty sure that cameras like the 300D and the 10D use a small amount of automatic in camera sharpening even in Adobe RGB raw mode. In the 1D line there is none unless you set it yourself in set 1, 2, or 3.

There might be sharpening amounts stored along with the raw file, but the original raw file is unsharpened -- you can adjust that with the slider.

I think the confusion is introduced in the distinction between what settings cause permanent changes to underlying data, and which settings tweak the algorithms that are applied to that data.
If we change any of the exposure parameters (shutter, ISO, aperture, Exp. Comp) we are either changing the sensor's sensitivity to light, or the amount of light we allow to reach the sensor sites. This inherently causes a change in the readings that end up in the RAW file's sensor data.
All of the other paramters may affect the way an image is displayed depending on the RAW converter. There's some confusion in Nikon land due to custom curves. Nikon Capture applies those curves when they are embedded in the image as metadat, but many converters will not. In most of the tools I've worked with it's pretty trivial to zero most of the settings. For example, Bibble applies a default sharpening which I can drop to zero. I can also change the tone curves to give me the linear interpolation rather than the more eye pleasing tone curves we normally see. These changes are all just input parameters to algorithms that are applied in creating what appears on-screen.

And to add to cghubbell's post, when converting in Adobe Camera Raw, there is a drop-down selection for the conversion for "camera default." this does not necessarily zero all changes, but does cancel the data modificatons that are based on (non-default) settings in force at the time the photo was taken.

Where is this drop down?

Sorry to be pedantic... |
(To) effect is a verb as well, but the meaning of effect is completely different from the meaning of affect.

When the converter dialog opens, it's immediately under the histogram. the default value is "selected image" which loads the settings written at exposure. You can also choose "custom", "Camera Default" or "Last Conversion". The last option is useful if you want to quickly reuse the settings you (manually) made on the last shot, but don't want to batch process.

Is there a raw converter plug in for PS6?

Zeus,
Yes that's correct, but it's a relatively rare usage. Oddly enough, I used "affect" in an equally rare way in the poem "Stuck Life" which is posted on the long self portrait thread.

CS only. There was one for PS 7, but it was pulled by Adobe when CS came out. Bibble has one for 7, probably works in 6
Go to the Canonusa website and find the rebel software page and Download DPP 1.5 (Digital Photo Professional). It is called the 'updater' on their site but it will install the full program. great and fast way to edit CRW files.

Don't have time right now, gotta get ready for work. Is this a free program?
And does it work in Win 98se?

Bear,
I enjoyed the pomme, but in it there's no 'affect' (the word) I could find. Mind you, I often read what I imagine is there or isn't.
