Hi,

When running gdal_translate to get rid of the 3th band of a 3 band RGB geotiff image:

gdal_translate -b 1 -b 2 sourcefilename outputfilename

It got rid of the 3rd band but it made the first band gray and the second band undefined which caused the new geotiff to be gray.

How can I keep the color of the first 2 bands when getting rid of the 3rd band

John,

TIFF does not have a concept of per-band color interpretation so you
essentially need to pick RGB for a 3 band file or grayscale for a 1-2
band file.

There just isn't a proper way of expressing what you want in TIFF format.

Best regards,
