Some questions about D100..

[SNAG]

Hi there all!
I managed to use a D100 today, and I took some shots.
But some questions:

1) Colour rendition was totally bad.
From reading the EXIF info, I realised that "Color Representation" was unknown. Is this the color space? Which one should I adjust to, and how do I adjust this?

2) I realised that shots taken by the D100 are rather underexposed. Read that this was normal. Is this true?

thanks a lot for answering my questions!

HI Snag,

Regarding this question no.2, what I heard from a friend who uses D100 the reasons behind it was:
Since D100 is a professional D-SLR system, the owner is "expected" to be able to do post-processing for the shots taken. Therefore, slightly underexposed photos will make a good candidates for such (post-processing) purposes as you won't be able to get back the details from the overexposed photos where the details is lost permanently.

If the camera is a conventional SLR system, the loss of details for an overexposed photos taken using a film is not that "bad" as compares to digital.

Please correct me if I am wrong.

regards.

1) Check to make sure that it has the latest firmware upgrade (v2.0). Check it when you go through the LCD display info. Also, check your WB; I have never gotten a bad skin color provided my WB is correct. That is why I've got the Gretag Macbeth ColorChecker for shoot large number of pictures.

2) When using the 3D Matrix metering, it will lower the exposure by about 0.3ev. This is to prevent overexposure, which cannot be recovered as the sensor was not able to capture the image. I've done beach shots that have the histogram ending at the 3/4 point. Unexposure can be recovered easily.

1) Depending on color mode (I, II, III) either sRGB (I, III) or Adobe RGB(1998) (II)

2) That's a common observation, looks alright to me. Underexpose better than blown out, tho.

cheers

yah correct... the color modes make a difference...
id just work with srgb mode I or III

for indoor people pictures, id go for mode I
for vibrant velvia like shots, id go for mode III

try it out for yourself and see the difference....
also play with the contrast setting as it affects the exposure latitude...
