firstly, I tried first method you said. Output was "READ_TIFF: D:\tmp\temp_opp\temp_exam.tiff: Cannot open
% Execution halted at: $MAIN$

Secondly, when I tried your second suggestion. Description of output (info, variable, index) were all undefined. And 'result' type is LONG and value is 0.

I tried to extract tiff images from different softwares again and again. It is so strange all tiff images cannot be read in IDL.
