You do realise that photos are usually in sRGB colour space and POV expects 
linear colour values?  By simply pasting the numbers into POV the colours in 
the resulting image are going to be washed out and probably of the incorrect 
hue...

Better to do a simple inverse gamma correction inside POV (the 2.2 here 
roughly approximates the sRGB -> linear conversion):

rgb <pow(128/255,2.2),pow(96/255,2.2),pow(250/255,2.2)>

That way the colours in your POV output image should match much better what 
you picked in the first place.
