hello,
in a study i would like to capture standardized photos of an object that is observed if it’s changing its color.
an example is the yellowing of a paper. to detect this, i need an apparature that guarantees same capturing conditions as light and "film-focus distance".
does someone have experiences with this problem?
second problem is how to determinate the colors correctly and, if necessary, change colors of the following photos digitally to the colors of the first photo.
here i’ve thought of using a test-picture in background that can give me a "mark" how my camera has changed natural colors. will it be possible to customize the color of the test-picture (beside the object) digitally and thus achieve the exact/same color of my object?
with many thanks in advance,
Jasper
P.S.:
am using Windows XP SP3
Pentium 4 3,0 GHz
2 GB RAM DDR2
Photoshop CS4
