Color ? Greyscale pic file transformation

Hi David,

this will give you a black and white scale, with black = 0 and white =
maximum (-s option):

$ falsecolor -ip image.hdr -r 'v' -g 'v' -b 'v' > image_fc.hdr

Is this what you want?

Cheers

Axel

I want to ask for your help
with dealing with pic files. Usually the results of Radiance
simulation of illuminance levels gives a spread of lines and values
by using colors or colored contours lines graphic representations.
I want to ask if there is
anyway to transform the results from a color based presentations, to
Black and White presentations? Transforming the usual color result
into greyscale presentation do not give the responding scale of grey
values - for example ? red is usually the color used for high
values, where once greyscaled, it gets a grey which is a middle hue
in relation to the others.

I will be very happy for an
advice for how to make a fit in between a color scale of values and a
grey scale of values for a pic result ?

Thank you very much!!
David
