Hi,<br><br>I suppose there is some command prompt command to do that easy and fast (Greg?).<br><br>For more complex solution you can download and install <a href="http://deluminaelab.com/en/raddisplay_download.html">RadDisplay</a> program. RadDisplay works on Windows and Linux.<br>
When you open pic image in the program, create False Color image and then press "Stats" button. In the dialog you 'll have various image statistics and average luminance too.<br><br><br>Hope this helps,<br>Marija<br>

Hi All,<br>
<br>
Can anybody help me with a simple problem?<br>
How do you evaluate the average value of a radiance (*.pic or *.hdr)<br>
image?<br>
Many thanks,<br>
