Did alittle test with in camera parameters

Hello everyone, ive always wondered this but never tested it.
Chock it up to late night bordom.

For the first shot, i set in the camera parameters to full saturation and full sharpness.
For the sencond shot the saturation and sharpness were both set to their normal positions.
The camera i performed this with was a EOS digital Rebel.

sharpness is difficult to tell when the image reduction is applied after the sharpening, but in terms of saturation, there is a visible difference.

what are your thoughts on the 2 pics. I cant say that with that subject, one version stands out more than the other.

Is that the Rebel XT?

Shooting Jpeg?

I don't have my XT anymore but I'm sure mine made much more difference when I tried playing with the parameters. I'll try it with my XTi/400D and see what that does.

Yes its an XT, yes shooting jpeg.
It does seem to not make a huge difference. Ill try again with a more contrasting shot and see if there is more of an obvious difference.

I can't really see a big difference in the pictures posted - maybe it's my screen, maybe it's my eyes - the look pretty much the same to me.
As I understand it, the camera does some sort of auto-adjust before saving jpeg images. Does these settings only apply to jpeg or do they also affect raw images?

Keheha, the parameters apply to both jpg and Raw but they are not permanent with Raw so you can change them in the Photo Pro.

In-camera settings do not get saved in a RAW image except as "sideline" information (my term). Many RAW conversion programs will use the information as "default" settings for the conversion process, but you can make whatever settings you want for the conversion.

With a JPG coming out of the camera with the various settings having modified the production of the image, there's really no way to "undo" the result of the settings - you need to further modify the actual image to make changes.

White balance is a really good example of this. When doing a RAW conversion, you can choose the white balance just as if you were doing it in the camera. The RAW image itself has no adjustments made to it. You can do the conversion process on a RAW image as many times as you care to with as many different settings as you like. You never affect the original RAW image in doing so. There is a companion file for a RAW image that is created in the process that "remembers" your RAW conversion settings, but the RAW image file itself is untouched. It's a lot like using a color negative. You can print it as many times with different filters and processes without affecting the negative itself.

The sharpness difference is readily apparent in the labels on the cans and bottles. I am glad to see that DP is available in So Cal. I have traveled to some areas and had to suffer without a DP fix while there.
